    Full Text Available The Long Term Evolution (LTE is a high data rates and fully All-IP network. It is developed to support well to multimedia services such as Video, VoIP, Gaming, etc. So that, the real-time services such as VoIP, video, etc. need to be optimized. Nevertheless, the deployment of such live stream services having many challenges. Scheduling and allocating radio resource are very important in LTE network, especially with multimedia services such as VoIP. When voice service transmitted over LTE network, it is affected by many network impairments where there are three main factors including packet loss, delay, and jitter. This study proposes a new scheduler which is based on VoIP priority mode,Wideband (WB E-model, QoS- and Channel-Aware (called WE-MQS-VoIP Priority scheduler for voice services in LTE downlink direction. The proposed scheduling scheme is built based on the WB E-model and Maximum Queue Size (MQS. In addition, we integrate the VoIP priority mode into our scheduling scheme. Since the proposed scheduler considers the VoIP priority mode and user perception, thus, it improves significantly the system performance. The results demonstrate that the proposed scheduler not only meets QoS demands of voice calls but also outperforms Modified Largest Weighted Delay First (M-LWDF in terms of delay, Packet Loss Rate (PLR for all number of user (NU and excepting NU equals 30, respectively. For Fairness Index (FI, cell throughput, and Spectral Efficiency (SE, the difference among the packet schedulers is not significant. The performance evaluation is compared in terms of Delay, PLR, Throughput, FI, and SE.

    2008-01-01

    Voice Service Providers (VSPs) participating in VoIP peering frequently want to withhold their identity and related privacy-sensitive information from other parties during the VoIP communication. A number of existing documents on VoIP privacy exist, but most of them focus on end user privacy. By summarizing and extending existing work, we present a unified privacy mechanism for both VoIP users and service providers. We also show a case study on how VSPs can use this mechanism for identity and topology hiding in VoIP peering.

    2007-08-01

    We propose a burst transmission method that guarantees the voice over Internet protocol (VoIP) service. The proposed method consists of three techniques: round-robin burst assembly with slotted scheduling, priority control with void filling, and hop-based preemption. Each technique is utilized so that the burst loss probability and the burst transmission delay satisfy VoIP quality of service (QoS). We evaluate by simulation the performance of the proposed method in NSFNET with 14 nodes. Numerical examples show that our proposed method is effective for guaranteeing the VoIP QoS while accommodating a large number of VoIP users.

However, most of the existing studies focused on a one-to-one communication model in a homogeneous network, instead of one-to-many broadcasting model among diverse embedded devices in a heterogeneous network. In this paper, we present the implementation of a VoIP broadcasting service on the open source—Linphone—in a heterogeneous network environment, including WiFi, 3G, and LAN networks. The proposed system featuring VoIP broadcasting over heterogeneous networks can be integrated with heterogeneous agile devices, such as embedded devices or mobile phones. VoIP broadcasting over heterogeneous networks can be integrated into modern smartphones or other embedded devices; thus when users run in a traditional AM/FM signal unreachable area, they still can receive the broadcast voice through the IP network. Also, comprehensive evaluations are conducted to verify the effectiveness of the proposed implementation.

  9. Influence of Security Mechanisms on the Quality of Service of VoIP

    Science.gov (United States)

    Backs, Peter; Pohlmann, Norbert

    While Voice over IP (VoIP) is advancing rapidly in the telecommunications market, the interest to protect the data transmitted by this new service is also rising. However, in contrast to other internet services such as email or HTTP, VoIP is real-time media, and therefore must meet a special requirement referred to as Quality-of-Service to provide a comfortable flow of speech. Speech quality is worsened when transmitted over the network due to delays in transmission or loss of packets. Often, voice quality is at a level that even prevents comprehensive dialog. Therefore, an administrator who is to setup a VoIP infrastructure might consider avoiding additional decreases in voice quality resulting from security mechanisms, and might leave internet telephony unprotected as a result. The inspiration for this paper is to illustrate that security mechanisms have negligible impact on speech quality and should in fact be encouraged.

  10. Fair Scheduling for Delay-Sensitive VoIP Traffic

    Ahmed, Shawish; Jiang, Xiaohong; Horiguchi, Susumu

    With the wide expansion of voice services over the IP networks (VoIP), the volume of this delay sensitive traffic is steadily growing. The current packet schedulers for IP networks meet the delay constraint of VoIP traffic by simply assigning its packets the highest priority. This technique is acceptable as long as the amount of VoIP traffic is relatively very small compared to other non-voice traffic. With the notable expansion of VoIP applications, however, the current packet schedulers will significantly sacrifice the fairness deserved by the non-voice traffic. In this paper, we extend the conventional Deficit Round-Robin (DRR) scheduler by including a packet classifier, a Token Bucket and a resource reservation scheme and propose an integrated packet scheduler architecture for the growing VoIP traffic. We demonstrate through both theoretical analysis and extensive simulation that the new architecture makes it possible for us to significantly improve the fairness to non-voice traffic while still meeting the tight delay requirement of VoIP applications.

    To decrease the transmission delay of uplink voice over IP (VoIP) services in IEEE 802.16e system, a novel strategy which includes a load-balance algorithm and an extended earliest deadline first (EEDF) scheduling algorithm is proposed. Subsequently, this paper analyzes the performance of the proposed strategy in terms of transmission delay of VoIP services, system capacity, throughput and compatibility with IEEE 802.16e standard. Finally, simulation experiments are carried out to verify the improvement of the proposed strategy. The simulation results match well with the theoretical analysis and show that the proposed strategy reduces the transmission delay of uplink VoIP services and improves the capacity and throughput. These improvements are remarkable especially when the load of system is heavy.

    The support of the voice over Internet Protocol (VoIP) services in next-generation wireless systems requires the coupling of mobility with quality of service. The mobile node can experience disruptions or even intermittent disconnections of an ongoing real-time session due to handovers....... The duration of such interruptions is called disruption time or handover delay and can heavily affect user satisfaction. Therefore, this delay needs to be minimized to provide good-quality VoIP services. In this paper, the focus is on the network layer mobility, specifically on dates for providing mobility...... in this paper. The results obtained using the adaptive timer technique show that for a 3% frame error rate and a 128-kb/s channel, the handoff delay is about 0.075 s (predictive) and 0.051 s (reactive) for FMIPv6. It is around 0.047 s [intra-mobile anchor point (MAP)] and 1.47 s (inter-MAP) for HMIPv6, around 1...

Gateways are the key component required to facilitate IP Telephony. A gateway is used to bridge the traditional circuit switched PSTN with the packet switched Internet. The paper covers software, hardware and protocol requirements followed by weighing the VoIP advantages such as low cost, portability, free and advanced features, bandwidth efficiency, call recording and monitoring against the VoIP disadvantages such as power dependency, quality of voice and service, security, and reliability. With ever increasing internet penetration and better broadband connectivity, VoIP is going to expand further with businesses already using VoIP standalone or in a hybrid format, although our focus and scope here remains VoIP. Mobile VoIP, an infant with less than 4% market share, has so far been focusing on increasing active subscriptions without a sustainable revenue model, but has the potential and is going to see tussle with static VoIP for space in days ahead.

    2012-04-01

    Full Text Available VoIP relies on packet switching, similar to the way that e-mails are sent over the Internet. The technology breaks down a voice call into bite-size information packets. Instead of keeping the switch open all the time, the information is sent and received as needed, allowing excess line capacity to be used to carry other data. When the voice data arrives at its destination, it's reassembled into a voice call. As voice over IP services grow in popularity, the potential for viruses, worms and other security threats aimed at the technology also will grow. The current paper's purpose is presenting several security solutions and applying them to integrated systems at an economical and social level.

    Full Text Available Nowadays, mobile ad hoc networks (MANETs have to support new applications including VoIP (voice over IP that impose stringent QoS (quality of service constraints and requirements. However, VoIP applications make a very inefficient use of the MANET resources. Our work represents a first step toward improving aspects at the network layer by addressing issues from the standpoint of adaptation, claiming that effective adaptation of routing parameters can enhance VoIP quality. The most important contribution is the adaptive OLSR-VA algorithm which provides an integrated environment where VoIP activity is constantly detected and routing parameters are adapted in order to meet the application requirements. To investigate the performance advantage achieved by such algorithm, a number of realistic simulations (MANET scenarios are performed under different conditions. The most important observation is that performance is satisfactory in terms of the perceived voice quality.

    Full Text Available Voice over IP (VoIP is commonly known as phone service over the Internet. Any service using public IP network requires certain extent of security. Demand for security in VOIP technology is increasing. VPN is one of the commonly used methods to secure VOIP traffic. In this paper we simulated behavior of a VOIP communication while running over a GRE VPN Tunnel using OPNET Modeler 17.5. During the simulation, such performance parameters as: choice of voice signaling protocol, voice Codec, parameters arising from network QoS (in this study, homogenous vs. heterogeneous network environment and type of VPN tunneling protocol, were examined. We evaluated performance of VOIP communications in homogenous and heterogeneous network environments, configured based on two different signaling protocols, namely H.323 and SIP. Also, G.711 and G.723 were configured and tested as the choice for voice Codecs. GRE was implemented as the tunneling protocol. Result analysis of this study indicated that GRE Tunnel didn't show a significant increase in such call quality of service (QoS performance factors as: end-to-end delay, call setup time, or a decrease in call MOS value. Even though in a non-ideal (heterogeneous network environment, call quality of service (QoS performance factors shoed poor results; however, there was no significant evidence to suggest that GRE Tunnel is the root cause for such poor results.

    In this paper, we analyze the extended real-time Polling Service (ertPS) algorithm in IEEE 802.16e systems, which is designed to support Voice-over-Internet-Protocol (VoIP) services with data packets of various sizes and silence suppression. The analysis uses a two-dimensional Markov Chain, where the grant size and the voice packet state are considered, and an approximation formula for the total throughput in the ertPS algorithm is derived. Next, to improve the performance of the ertPS algorithm, we propose an enhanced uplink resource allocation algorithm, called the e2rtPS algorithm, for VoIP services in IEEE 802.16e systems. The e2rtPS algorithm considers the queue status information and tries to alleviate the queue congestion as soon as possible by using remaining network resources. Numerical results are provided to show the accuracy of the approximation analysis for the ertPS algorithm and to verify the effectiveness of the e2rtPS algorithm.

    Full Text Available People have been utilizing Voice over Internet Protocol (VoIP in most of the conventional communication facilities which has been of assistance in the enormous attenuation of operating costs, as well as the promotion of next- generation communication services-based IP. As an intimidating upshot, cyber criminals have correspondingly started interjecting the environment and creating new challenges for the law enforcement system in any Country. This paper presents an idea of a framework for the forensic analysis of the VoIP traffic over the network. This forensic activity includes spotting and scrutinizing the network patterns of VoIP-SIP stream, which is used to initiate a session for the communication, and regenerate the content from VoIP-RTP stream, which is employed to convey the data. Proposed network forensic investigation framework also accentuates on developing an efficient packet restructuring algorithm for tracing the depraved users involved in a conversation. Network forensics is the basis of proposed work, and performs packet level surveillance of VoIP followed by reconstruction of original malicious content or network session between users for their prosecution in the court.

    Abstract Voice quality on VoIP communication is caused by many factors, one of which is the quality of the server. Choosing PC platform or server which is suitable is the main issue in developing VoIP network. A bad server performance or not equivalent with the most of users will degrade the sound quality or even not able to connect between users. Tthe test carried out to the performance of the wireless access point Linksys WRT54GL which is used as a VoIP server. The test was carried out to determine how many VoIP calls which are able to be serviced by a wireless access point as a VoIP server and how long the server needs to be able to process every signal of SIP and RTP packet. Based on the test result performed, the VoIP server on the wireless access point is able to serve VoIP communication well for a few calls number, so it is worth to be implemented on the use of small scale. The use of Native Bridging method in handling the media performed by the server can increase the number of calls that were able to be served about 3 to 7 times compared with other methods.     Keywords— VoIP, Asterisk, Acess Point, WRT54GL, OpenWRT, Performance

    The technology of transmitting voice over data networks has been available for over 10 years. Mass market VoIP services for consumers to make and receive standard telephone calls over broadband Internet networks have grown in the last 5 years. While operational costs are less with VoIP implementations as opposed to time division multiplexing (TDM) based voice switches, is it still advantageous to convert a mission control center s voice system to this newer technology? Marshall Space Flight Center (MSFC) Huntsville Operations Support Center (HOSC) has converted its mission voice services to a commercial product that utilizes VoIP technology. Results from this testing, design, and installation have shown unique considerations that must be addressed before user operations. There are many factors to consider for a control center voice design. Technology advantages and disadvantages were investigated as they refer to cost. There were integration concerns which could lead to complex failure scenarios but simpler integration for the mission infrastructure. MSFC HOSC will benefit from this voice conversion with less product replacement cost, less operations cost and a more integrated mission services environment.

    VoIP is a service that changes the analogue audio signal into a digital signal and then transfers the audio information to the users after configuring it as a packet; and it has an advantage of lower price than the existing voice call service and better extensibility. However, VoIP service has a system structure that, compared to the existing PSTN (Public Switched Telephone Network), has poor call quality and is vulnerable in the security aspect. To make up these problems, TLS service was introduced to enhance the security. In practical system, however, since QoS problem occurs, it is necessary to develop the VoIP security system that can satisfy QoS at the same time in the security aspect. In this paper, a user authentication VoIP system that can provide a service according to the security and the user through providing a differential service according to the approach of the users by adding AA server at the step of configuring the existing VoIP session is suggested. It was found that the proposed system of this study provides a quicker QoS than the TLS-added system at a similar level of security. Also, it is able to provide a variety of additional services by the different users.

    Full Text Available Voice over Internet Protocol (VoIP is a new communication technology that uses internet protocol in providing phone services. VoIP provides various forms of benefits such as low monthly fee and cheaper rate in terms of long distance and international calls. However, VoIP is accompanied with novel security threats. Criminals often take advantages of such security threats and commit illicit activities. These activities require digital forensic experts to acquire, analyses, reconstruct and provide digital evidence. Meanwhile, there are various methodologies and models proposed in detecting, analysing and providing digital evidence in VoIP forensic. However, at the time of writing this paper, there is no model formalized for the reconstruction of VoIP malicious attacks. Reconstruction of attack scenario is an important technique in exposing the unknown criminal acts. Hence, this paper will strive in addressing that gap. We propose a model for reconstructing VoIP malicious attacks. To achieve that, a formal logic approach called Secure Temporal Logic of Action(S-TLA+ was adopted in rebuilding the attack scenario. The expected result of this model is to generate additional related evidences and their consistency with the existing evidences can be determined by means of S-TLA+ model checker.

    Mazurczyk, Wojciech; Szczypiorski, Krzysztof

    2010-01-01

    Voice over IP (VoIP) is unquestionably the most popular real-time service in IP networks today. Recent studies have shown that it is also a suitable carrier for information hiding. Hidden communication may pose security concerns as it can lead to confidential information leakage. In VoIP, RTP (Real-time Transport Protocol) in particular, which provides the means for the successful transport of voice packets through IP networks, is suitable for steganographic purposes. It is characterised by a high packet rate compared to other protocols used in IP telephony, resulting in a potentially high steganographic bandwidth. The modification of an RTP packet stream provides many opportunities for hidden communication as the packets may be delayed, reordered or intentionally lost. In this paper, to enable the detection of steganographic exchanges in VoIP, we examined real RTP traffic traces to answer the questions, what do the "normal" delays in RTP packet streams look like? and, is it possible to detect the use of know...

    2011-11-01

    Full Text Available VoIP (voice over internet protocol is very popular communication technology of this century and has played tremendous role in communication system. It is preferred by all because it deploys many benefits it uses Internet protocol (IP networks to deliver multimedia information such as speech over a data network. VoIP system can be configured in these connection modes respectively; PC to PC, Telephony to Telephony and PC to Telephony. Echo is very annoying problem which occurs in VoIP and echo reduces the voice quality of VoIP. It is not possible to remove echo 100% from echoed signal because if echo is tried to be eliminated completely then the attempt may distort the main signal. That is why echo cannot be eliminated echo perfectly but the echo to a tolerable range. Clipping is not a good solution to suppress echo because part of speech may erroneously removed. Besides an NLP does not respond rapidly enough and also confuses the fading of the voice level at the end of a sentence with a residual echo. This paper has proposed echo cancellation in VoIP that has been tested and verified by MATLAB. The goal was to suppress echo without clipping and distorting the main signal. By the help of MATLAB program the echo is minimized to enduring level so that the received signal seems echo free. The percentage of suppressing echo varies with the amplitude of the main signal. With regarding the amplitude variation in received (echo free signal the proposed method performs better in finding the echo free signal than the other conventional system.

    Full Text Available The main goal of VoIP services is to provide a reliable and high-quality voice transmission over packet networks. In order to prove the quality of VoIP transmission, several approaches were designed. In our approach, we are concerned about on-line monitoring of RTP and RTCP traffic. Based on these data, we are able to compute main VoIP quality metrics including jitter, delay, packet loss, and finally R-factor and MOS values. This technique of VoIP quality measuring can be directly incorporated into IPFIX monitoring framework where an IPFIX probe analyses RTP/RTCP packets, computes VoIP quality metrics, and adds these metrics into extended IPFIX flow records. Then, these extended data are stored in a central IPFIX monitoring system called collector where can be used for monitoring purposes. This paper presents a functional implementation of IPFIX plugin for VoIP quality measurement and compares the results with results obtained by other tools.

    Guo, Fanglu; Chiueh, Tzi-cker

    2008-01-01

    An emerging killer application for enterprise wireless LANs (WLANs) is voice over IP (VoIP) telephony, which promises to greatly improve the reachability and mobility of enterprise telephony service at low cost. None of the commercial IEEE 802.11 WLAN-based VoIP products can support more than ten G.729-quality voice conversations over a single IEEE 802.11b channel on real-world WLANs, even though the physical transmission rate is more than two orders of magnitude higher than an individual VoIP connection's bandwidth requirement. There are two main reasons why these VoIP systems' effective throughput is significantly lower than expected: VoIP's stringent latency requirement and substantial per-WLAN-packet overhead. Time-Division Multiple Access (TDMA) is a well-known technique that provides per-connection QoS guarantee as well as improves the radio channel utilization efficiency. This paper compares the effective throughput of IEEE 802.11, IEEE 802.11e and a software-based TDMA (STDMA) protocol that is specifically designed to support WLAN-based VoIP applications, on the same commodity IEEE 802.11 WLAN hardware. Empirical measurements from a VOIP over WLAN testbed show that the numbers of G.729-quality voice conversations that IEEE 802.11, IEEE 802.11e and STDMA can support over a single IEEE 802.11b channel are 18, 22 and 50, respectively.

  3. Application Oriented Flow Routing Algorithm for VoIP Overlay Networks

    Science.gov (United States)

    Wipusitwarakun, Komwut; Chimmanee, Sanon

    Overlay networks which are dynamically created over underlying IP networks are becoming widely used for delivering multimedia contents since they can provide several additional user-definable services. Multiple overlay paths between a source-destination overlay node pair are designed to improve service robustness against failures and bandwidth fluctuation of the underlying networks. Multimedia traffic can be distributed over those multiple paths in order to maximize paths' utilization and to increase application throughputs. Most of flow-based routing algorithms consider only common metrics such as paths' bandwidth or delay, which may be effective for data applications but not for real-time applications such as Voice over IP (VoIP), in which different levels of such performance metrics may give the same level of the performance experienced by end users. This paper focuses on such VoIP overlay networks and proposes a novel alternative path based flow routing algorithm using an application-specific traffic metric, i.e. “VoIP Path Capacity (VPCap), ” to calculate the maximum number of QoS satisfied VoIP flows which may be distributed over each available overlay path at a moment. The simulation results proved that more QoS-satisfied VoIP sessions can be established over the same multiple overlay paths, comparing to traditional approaches.

    Full Text Available Voice over Internet Protocol (VoIP is becoming a reality in many organizations. The potential for mobility in voice over wi-fi networks will derive demand for the technology. Wireless VoIP is poised to rival VoIP as an alternative telephony tool. Internet has been used to transport data in the form of packet. In the past, Internet did not support any kind of sophisticated quality of service (QoS mechanism. Although the type of service (TOS field in the Internet protocol (IP header has been existing and has been allowing the differentiated treatment of packets, it was never really used on a large scale. The voice is sensitive to delay and jitter so bandwidth must be guaranteed while transporting it. With the extensive use of Internet for carrying voice, there is a need to add QoS functionality in it. QoS with reference to VoIP has been discussed in the paper. Limited bandwidth and network latency are the issues which need to be considered while using wireless LAN for packetized voice data. Efforts of standards like 802.11e which will take care of these issues, have also been explored. The impact of these technologies on distance education has also been explored in the paper.

For VoIP, it is very important to take into consideration the need to provide a high quality service according to well-defined standard transmission (jitter, end-to-end delay, MOS, and packet loss. However, wireless networks (IEEE 802.11 are based on radio which undergoes a number of technical constraints to achieve theoretical transmission rates; among these constraints the number of users of the networks, the distance between the client and the access, and the amount of data transmitted point are included. In this term, a study is made by simulating wireless network in OPNET Modeler with a fairly large number of VoIPs (15 users whose signaling is handled via a new node that was created specifically to manage the signaling tasks under SIP and H.323 in order to minimize the number of nodes in the network and avoid the congestion. In this paper, two scenarios are compared; the first contains a number of VoIP users with SIP and H.323 signaling handled by the new created device; the second scenario is similar to the first except that the distance between the stations is remarkably lower.

    In this paper, we circumscribe available steganographic techniques that can be used for creating covert channels for VoIP (Voice over Internet Protocol) streams. Apart from characterizing existing steganographic methods we provide new insights by presenting two new techniques. First one is network steganography solution and exploits free/unused fields of the RTCP (Real-Time Control Protocol) and RTP (Real-Time Transport Protocol) protocols. The second method provides hybrid storage-timing covert channel by utilizing delayed audio packets. The results of the experiment, that was performed, regardless of steganalysis, to estimate a total amount of data that can be covertly transferred in VoIP RTP stream during the typical call, are also included in this article.

    Full Text Available VoIP is a system that uses the Internet network to transmit voice packets from one place to another using IP protocols intermediaries. With VoIP technology can be much cheaper call charges, especially for communicating overseas because of voice and data using the same network ie the Internet network. VoIP is a service that is very susceptible to delay while the existing access network is currently providing a significant delay for VoIP. One alternative network that can be used to overcome these problems is to use WiMAX technology because WiMAX can provide speed data services up to 70 Mbps.From the research,  results of one way delay, jitter and packet loss still at the value recommended by ITU-T, which is the maximum value of one way delay measurement is 159.87 ms, for jitter 7.52 ms and for packet loss is 3.175%. The one way delay and packet loss from the measurement used to find the MOS score which is the value for quality of VoIP. MOS value range obtained from the calculation of 3.6 to 4.2, which means VoIP feasible to apply to the WiMAX network. The maximum value can reach 2.8 Mbps throughput to 0.575 Mbps for downlink and uplink. From the research also found that the SQI values that are above the standard value of the device will provide a high SNR value, and the higher SQI values then its RSSI value is also bigger.

    Full Text Available IP based voice transmission technology is a flexible, simpler and a cost effective implementation of voicetransmission. It provides a real convergence of various networks. This voice transmission technology doesnot support a quality that is equivalent to digitized voice, which is available in the existing PSTN networks.In addition to this, data network vulnerabilities affect the VOIP service causing a drop in the utilization ofvoice communication. In this paper, the quality of service for voice calls is ensured with the integration ofCAC mechanism with the bandwidth link utilization which makes an estimation of the demandedbandwidth. In terms of security, prevention of ARP cache poisoning attack is achieved by use of the signedMAC address response in local area networks. It makes the network confident that the admitted user is anauthorized user and also it verifies that only the authorized users’ information is exchanged over the localarea network. Also an approach that makes it difficult for the hacker’s to hack the data exchanged over thequality channel has been proposed.

    Bhanu, S Vijay; Balakrishnan, V

    2010-01-01

    Voice over Internet protocol (VoIP) is one of the most important applications for the IEEE 802.11 wireless local area networks (WLANs). For network planners who are deploying VoIP over WLANs, one of the important issues is the VoIP capacity. VoIP bandwidth consumption over a WAN is one of the most important factors to consider when building a VoIP infrastructure. Failure to account for VoIP bandwidth requirements will severely limit the reliability of a VoIP system and place a huge burden on the WAN infrastructure. Less bandwidth utilization is the key reasons for reduced number of channel accesses in VOIP. But in the QoS point of view the free bandwidth of atleast 1-5% will improve the voice quality. This proposal utilizes the maximum bandwidth by leaving 1-5% free bandwidth. A Bandwidth Data rate Moderation (BDM) algorithm has been proposed which correlates the data rate specified in IEEE802.11b with the free bandwidth. At each time BDM will calculate the bandwidth utilization before sending the packet to i...

    Full Text Available Real-time services such as VoIP are becoming popular and are major revenue earners for network service providers. These services no longer confined to the wired domain and extended over wireless networks. Although some of the existing wireless technologies can support some low-band width applications, the bandwidth demands of many multimedia applications exceed the capacity of these technologies. The WiMAX promises to be one of the wireless access technologies capable of supporting very high bandwidth applications. However, there are still many challenges that need to be addressed to provide a steady and good quality voice connection over the best-effort WiMAX network. In This paper, we evaluate the performance of different VoIP codecs over the WiMAX network. The network performance metrics such as MOS, packet end-to-end delay, jitter and packet delay variation have been used to evaluate the performance of VoIP codecs. The results showed that, the codec G.723 provides the best results among all discussed Codecs in all presented performance metrics; the lowest delay, the highest MOS and the highest Throughput.

    Full Text Available In this research, we propose an optimization method based-on E-Model for designing an efficient low speed VoIP network for Rural Next Generation Network (R-NGN. We are choosing 128 kbps and 256 kbps bandwidth as the typical community link to be used in the designing of R-NGN infrastructure. The method is based on selection of some VoIP network parameters such as voice coder, communication protocol, packet loss level, network utilization and resource allocation. We draw analytic approach for achieving rating value (R of E-model that represent level of quality of service. In this approach, we focus on delay and packet loss calculation to find the rating value. We state the rating value = 70 as minimum level of quality of service for each call, equivalent to 3.6 of Mean Opinion Score (MOS. In our experiments, either G.723.1 5.3 kbps or G.729 is chosen for maximizing the number of VoIP calls, it depends on link utilization and level of packet loss.

    The VoIP services provide fertile ground for criminal activity, thus identifying the transmitting computer devices from recorded VoIP call may help the forensic investigator to reveal useful information. It also proves the authenticity of the call recording submitted to the court as evidence. This paper extended the previous study on the use of recorded VoIP call for blind source computer device identification. Although initial results were promising but theoretical reasoning for this is yet to be found. The study suggested computing entropy of mel-frequency cepstrum coefficients (entropy-MFCC) from near-silent segments as an intrinsic feature set that captures the device response function due to the tolerances in the electronic components of individual computer devices. By applying the supervised learning techniques of naïve Bayesian, linear logistic regression, neural networks and support vector machines to the entropy-MFCC features, state-of-the-art identification accuracy of near 99.9% has been achieved on different sets of computer devices for both call recording and microphone recording scenarios. Furthermore, unsupervised learning techniques, including simple k-means, expectation-maximization and density-based spatial clustering of applications with noise (DBSCAN) provided promising results for call recording dataset by assigning the majority of instances to their correct clusters.

    2010-08-01

    Full Text Available The Voice over Internet Protocol (VoIP technology is cheaper and does not need new infrastructure because it has available in the global computer (IP network. Unfortunately, transition from PSTN to VoIP networks have emerged new problems in voice quality. Furthermore, the transmission of voice over IP networks can generate network congestion due to weak supervision of the traffic incoming packet, queuing and scheduling. This congestion affects the Quality of Service (QoS such as delay, packet drop and packet loss. Packet delay effects will affect the other QoS such as: unstable voice packet delivery, packet jitter, packet loss and echo. Priority Queuing (PQ algorithm is a popular technique used in the VoIP network to reduce delays. But, the method can result in repetition. This recursive leads to the next queue starved. To solving problems, there are three phases namely queuing, classifying and scheduling. It will be applied to the fuzzy inference system to classify the queuing incoming packet (voice, video and text. To justify the research of the improved PQ algorithm be compared against the algorithm existing.

    Soupionis, Yannis; Tountas, George; Gritzalis, Dimitris

    Voice over IP (VoIP) introduces new ways of communication, while utilizing existing data networks to provide inexpensive voice communications worldwide as a promising alternative to the traditional PSTN telephony. SPam over Internet Telephony (SPIT) is one potential source of future annoyance in VoIP. A common way to launch a SPIT attack is the use of an automated procedure (bot), which generates calls and produces audio advertisements. In this paper, our goal is to design appropriate CAPTCHA to fight such bots. We focus on and develop audio CAPTCHA, as the audio format is more suitable for VoIP environments and we implement it in a SIP-based VoIP environment. Furthermore, we suggest and evaluate the specific attributes that audio CAPTCHA should incorporate in order to be effective, and test it against an open source bot implementation.

    Voice communication over internet not be possible without a reliable data network, this was first available when distributed network topologies were used in conjunction with data packets. Early network used single centre node network in which a single workstation (Server) is responsible for the communication. This posed problems as if there was a fault with the centre node, (workstation) nothing would work. This problem was solved by the distributed system in which reliability increases by spreading the load between many nodes. The idea of packet switching & distributed network were combined, this combination were increased reliability, speed & responsible for voice communication over internet, Voice-over-IP (VoIP)These data packets travel through a packet-switched network such as the Internet and arrive at their destination where they are decompressed using a compatible Codec (audio coder/decoder) and converted back to analogue audio. This paper deals with the Simulink architecture for VoIP network.

    Full Text Available Purpose: This paper aims at defining the value creation mechanism and income distribution strategies of product-service integration in order to promote product-service integration of a firm.Design/methodology/approach: This paper conducts researches quantitatively on the coordination mechanism of product-service integration by using game theory, and uses the methods of Shapley value and Equal growth rate to further discuss income distribution strategies of product-service integration.Findings: Product-service integration increases the total income of a firm and the added value of the income decreases as the unit price demand variation coefficient of products and services increases, while decreases as the marginal cost of products increases, decreases as the marginal cost of services increases. Moreover, the findings suggest that both income distribution strategies of product-service integration based on Shapley value method and Equal growth rate method can make the product department and service department of a firm win-win and realize the pareto improvement. The choice of what kind of distribution strategy to coordinate the actions between departments depends on the department playing dominant role in the firm. Generally speaking, for a firm at the center of market, when the product department is the main contributor to firm income, the service department will choose the income distribution strategy of product-service integration based on Shapley value method; when the service department is the main contributor to firm income, the service department will choose the income distribution strategy of product-service integration based on Equal growth rate method.Research limitations/implications: This paper makes some strict assumptions such as complete information, risk neutral, linear cost function and so on and the discussion is limited to the simple relationship between product department and service department.Practical implications: Product-service

    Due to its large coverage area, low cost of deployment and high speed data rates, WiMAX is a promising technology for providing wireless last-mile connectivity. Physical and MAC layer of this technology refer to the IEEE 802.16e standard, which defines 5 different data delivery service classes that can be used in order to satisfy Quality of Service (QoS) requirements of different applications, such as VoIP, videoconference, FTP, Web, etc. The main aim of the paper is to examine a case of QoS deployment over a cellular WiMAX network. In particular, the paper compares the performance obtained using two different QoS configurations differing from the delivery service class used to transport VoIP traffic, i.e. UGS or ertPS. Results indicate that for delay-sensitive traffic that fluctuates beyond its nominal rate, having the possibility to give back some of its reserved bandwidth, ertPS has the advantage to permit the transmission of BE traffic.

Using the data from the Children's Treatment Network (CTN, we aimed to measure the degree of integration for the CTN agencies in York and Simcoe.  Theory and Methods: We quantified the integration by the agreement between perceived and expected levels of involvement and calculated four scores from different perspectives for each agency. We used the average score to measure the global network integration and examined the sensitivity of the global score.  Results: Most agencies' integration scores were less than 65%. As measured by the agreement between every other agency's perception and expectation, the overall integration of CTN in Simcoe and York was 44% (95% CI: 39% - 49% and 52% (95% CI: 48% - 56%, respectively. The sensitivity analysis showed that the global scores were robust.  Conclusion: Our method extends existing measures of integration and possesses a good extent of validity. We can also apply the method in monitoring improvement and linking integration with other outcomes.

  12. Integrating mental health services: the Finnish experience

    Ville Lehtinen

    2001-06-01

    Full Text Available The aim of this paper is to give a short description of the most important developments of mental health services in Finland during the 1990s, examine their influences on the organisation and provision of services, and describe shortly some national efforts to handle the new situation. The Finnish mental health service system experienced profound changes in the beginning of the 1990s. These included the integration of mental health services, being earlier under own separate administration, with other specialised health services, decentralisation of the financing of health services, and de-institutionalisation of the services. The same time Finland underwent the deepest economic recession in Western Europe, which resulted in cut-offs especially in the mental health budgets. Conducting extensive national research and development programmes in the field of mental health has been one typically Finnish way of supporting the mental health service development. The first of these national programmes was the Schizophrenia Project 1981–97, whose main aims were to decrease the incidence of new long-term patients and the prevalence of old long-stay patients by developing an integrated treatment model. The Suicide Prevention Project 1986–96 aimed at raising awareness of this special problem and decreasing by 20% the proportionally high suicide rate in Finland. The National Depression Programme 1994–98 focused at this clearly increasing public health concern by several research and development project targeted both to the general population and specifically to children, primary care and specialised services. The latest, still on-going Meaningful Life Programme 1998–2003 which main aim is, by multi-sectoral co-operation, to improve the quality of life for people suffering from or living with the threat of mental disorders. Furthermore, the government launched in 1999 a new Goal and Action Programme for Social Welfare and Health Care 2000–2003, in

    2012-09-01

    Full Text Available The Voice over Internet Protocol (VoIP is increasing in popularity as a cost effective and efficient means of making telephone calls via the Internet. However, VoIP may also be an attractive method of communication to criminals as their true identity may be hidden and voice and video communications are encrypted as they are deployed across the Internet. This produces in a new set of challenges for forensic analysts compared with traditional wire-tapping of the Public Switched Telephone Network (PSTN infrastructure, which is not applicable to VoIP. Therefore, other methods of recovering electronic evidence from VoIP are required.  This research investigates the analysis and recovery of digitised human, which persists in computer memory after a VoIP call.This paper proposes a proof of concept how remnants of digitised human speech from a VoIP call may be identified within a forensic memory capture based on how the human voice is detected via a microphone and encoded to a digital format using the sound card of your personal computer. This digital format is unencrypted whist processed in Random Access Memory (RAM before it is passed to the VoIP application for encryption and  transmission over the Internet. Similarly, an incoming encrypted VoIP call is decrypted by the VoIP application and passes through RAM unencrypted in order to be played via the speaker output.A series of controlled tests were undertaken whereby RAM captures were analysed for remnants of digital speech after a VoIP audio call with known conversation. The identification and analysis of digital speech from RAM attempts to construct an automatic process for the identification and subsequent reconstruction of the audio content of a VoIP call.

  14. DEEPENING SERVICES MARKET INTEGRATION - A CRITICAL ASSESSMENT

    2007-12-01

    Full Text Available The greatest asset of the European Union is undoubtedly its internal market. However, the internal market is not completed: it suffers from a giant hole with respect to many services. The present contribution addresses the status of services in the internal market and, in particular, the horizontal liberalisation (or, the lack of it of services outside the two large sectors which greatly deepened market integration (6 modes of transport and 3 financial services markets. Because a horizontal perspective on services in the EU is still little understood, it is briefly summarized what services really are and how their regulatory logic in the internal market can help to classify them. The (strong economic case for deepening services market integration is built on recent empirical economic analysis as well as simulation. This is followed by a discussion, with flowchart, of the Bolkestein draft directive, against the backdrop of the frustrating lack of, or at best, selective progress on services for decades. A survey of economic impact studies of the draft directive is provided, too, underpinning its importance even when the infamous origin principle is taken out. Some light is subsequently shed on the tumultuous politicisation of the services debate. Emphasis is laid on the socio-economic context (which, it is submitted, sharpened the discussion at times into polarisation and a series of other factors such as the diversity of the national regulatory frameworks of services and the labour employed, the complexity of the draft directive, the potentially radical nature of the origin principle (especially for those not aware of the case law of the ECJ, the dominant role of the EP and the opportunism of leading national politicians. Finally, directive 2006/123 –meanwhile in force – is explained and briefly assessed. Apart from the conspicuous manifestation of 'Angst' in drafting the directive, the (de merits are set out. The conclusion is that a badly

    Full Text Available Transmission of VoIP over packet switching networks is one of the rapidly emerging real-time Internet Protocol. The real-time application of the Voice over Internet Protocol (VoIP is growing rapidly for it is more flexible than the traditional Public Switched Telephone Networks systems (PSTN. Meanwhile, the VoIP deployment on Wireless Local Area Networks (WLANs, which is based on IEEE 802.11 standards, is increasing. Currently, many schedulers have been introduced such as Weighted Fair Queueing (WFQ, Strict Priority (SP General processor sharing (GPS, Deficit Round Robin (DRR, andContention-Aware Temporally fair Scheduling (CATS. Unfortunately, the current scheduling techniques have some drawbacks on real-time applications and therefore will not be able to handle the VoIP packetsin a proper way. The objective of this research is to propose a new scheduler system model for the VoIP application named Voice Priority Queue (VPQ scheduler. The scheduler system model is to ensureefficiency by producing a higher throughput and fairness for VoIP packets. In this paper, only the First Stage of the VPQ packet scheduler and its algorithm are presented. Simulation topologies for VoIP traffic were implemented and analyzed using the Network Simulator (NS-2. The results show that this method can achieve a better and more accurate VoIP quality throughput and fairness index.

    Full Text Available VoIP (Voice Over IP is becoming an alternative way of voice communications over the Internet. To better utilize voice call bandwidth, some standard compression algorithms are applied in VoIP systems. However, these algorithms affect the voice quality with high compression ratios. This paper presents a lossless data reduction technique to improve VoIP data transfer rate over the IP network. The proposed algorithm exploits the data redundancies in digitized VFs (Voice Frames generated by VoIP systems. Performance of proposed data reduction algorithm has been presented in terms of compression ratio. The proposed algorithm will help retain the voice quality along with the improvement in VoIP data transfer rates.

  2. Integrating occupational health services and occupational prevention services.

    Rudolph, L; Deitchman, S; Dervin, K

    2001-09-01

    Despite the human and monetary costs of occupational injury and illness, occupational health care has focused more on treatment than prevention, and prevention is not part of many clinical occupational health practices. This represents a failure of occupational health care to meet the health care needs of the working patients. MEDLINE searches were conducted for literature on occupational medical treatment and the prevention of occupational injury and illness were reviewed to for linkages between prevention and treatment. Policy discussions which identify examples of programs that integrated prevention and treatment were included. Although examples of the integration of clinical and preventive occupational health services exist, there are challenges and barriers to such integration. These include inaction by clinicians who do not recognize their potential role in prevention; the absence of a relationship between the clinician and an employer willing to participate in prevention; economic disincentives against prevention; and the absence of tools that evaluate clinicians on their performance in prevention. Research is needed to improve and promote clinical occupational health preventive services. Copyright 2001 Wiley-Liss, Inc.

    Home care is the fastest growing segment of the Canadian healthcare system, yet research on patient safety has been conducted predominantly in institutional settings. This is a case example of how Victorian Order of Nurses Canada, a national not-for-profit home and community care provider, embedded a nurse researcher to create an environment in which health services research flourished. This model strategically propelled important issues such as home care safety on to the national research and policy agendas and helped leverage change in multiple levels of the healthcare system. This is a call to action for building partnerships to have a researcher as an integral team member in organizations providing home care services. © 2015 The Canadian College of Health Leaders.

    Directory of Open Access Journals (Sweden)

    Gina Browne

    2004-05-01

    Full Text Available Purposes: This paper proposes both a model and a measure of human service integration through strategic alliances with autonomous services as one way to achieve comprehensive health and social services for target populations. Theory: Diverse theories of integrated service delivery and collaboration were combined reflecting integration along a continuum of care within a service sector, across service sectors and between public, not-for-profit and private sectors of financing services. Methods: A measure of human service integration is proposed and tested. The measure identifies the scope and depth of integration for each sector and service that make up a total service network. It captures in quantitative terms both intra and inter sectoral service integration. Results: Results are provided using the Human Service Measure in two networks of services involved in promoting Healthy Babies and Healthy Children known to have more and less integration. Conclusions: The instrument demonstrated discriminate validity with scores correctly distinguishing the two networks. The instrument does not correlate (r=0.13 with Weiss (2001 measure of partnership synergy confirming that it measures a distinct component of integration. Discussion: We recommend the combined use of the proposed measure and the Weiss (2001 measure to more completely capture the scope and depth of integration efforts as well as the nature of the functioning of a service program or network.

    To achieve information integration, process integration and application integration of enterprise, an enterprise integration platform (EIP) based on service-oriented architecture (SOA) is built. The enterprise integration model depending on encapsulating the business processes as well as the enterprise applications by the neutral and standard web services is presented. The problem how to discover the existed enterprise resources and share them was resolved depending on the mechanism of publishing and discovering the services. The EIP is integrated closely with product lifecycle management (PLM) system so that the process integration as well as orchestration of the business process services is implemented by encapsulating the workflow engine of PLM system. Not only process integration and application integration, but also information integration based on the bill of material (BOM) conversion driven by process are achieved. Finally, an interpretive, qualitative case study on EIP is conducted for this research.

    2015-08-01

    To enhance their business opportunities, organisations involved in many service industries are increasingly active in pursuit of both online provision of their business services (BSs) and collaborating with others. Collaborative Networks (CNs) in service industry sector, however, face many challenges related to sharing and integration of their collection of provided BSs and their corresponding software services. Therefore, the topic of service interoperability for which this article introduces a framework is gaining momentum in research for supporting CNs. It contributes to generation of formal machine readable specification for business processes, aimed at providing their unambiguous definitions, as needed for developing their equivalent software services. The framework provides a model and implementation architecture for discovery and composition of shared services, to support the semi-automated development of integrated value-added services. In support of service discovery, a main contribution of this research is the formal representation of services' behaviour and applying desired service behaviour specified by users for automated matchmaking with other existing services. Furthermore, to support service integration, mechanisms are developed for automated selection of the most suitable service(s) according to a number of service quality aspects. Two scenario cases are presented, which exemplify several specific features related to service discovery and service integration aspects.

  12. Preliminary Investigations of Challenges in Dynamic Integration of Heterogeneous Services

    2016-02-01

    Full Text Available The progress of technology prompted the proliferation of services. Services are distinct, loosely coupled units of functionalities that are self-contained. These services are however developed by various vendors without following appropriate standards. However, the need for interoperability and reusability prompts the need for service integration. Service integration is not a new arena but emphasis is mostly on homogeneous services. However, the challenge lies on the integration of heterogeneous services to enforce reusability and maximize Total Cost of Deployment (TCD and Total Cost of Ownership (TCO at organization level. The issue of service integration has become critical, due to the increase of these diverse services as they have different platforms, architecture and use different programming languages. The current methods of integrating heterogeneous services are manual integration methods. Therefore, the challenge with the current methods is time consumption, lack of flexibility, cost (TCO and TCD, total time to development, because the process is manual. In this paper, we explore the challenges regarding dynamic integration of heterogeneous services and identify key issues that need to be addressed, in order to develop a successful mechanism that will enable dynamic integration of heterogeneous services.

    The purpose of Enterprise Application Integration (EAI) is to enable the interoperability between two or more enterprise software systems. These systems, for example, can be an Enterprise Resource Planning (ERP) system, an Enterprise Asset Management (EAM) system or a Condition Monitoring system. Traditional EAI approach, based on point-to-point connection, is expensive, vendor specific with limited modules and restricted interoperability with other ERPs and applications. To overcome these drawbacks, the Web Service based EAI has emerged. It allows the integration without point to point linking and with less costs. Many approaches of Web service based EAI are combined with ORACLE, SAP, PeopleSoft, WebSphere, SIEBEL etc. as a system integration platform. The approach still has the restriction that only predefined clients can access the services. This means clients must know exactly the protocol for calling the services and if they don't have the access information they never can get the services. This is because these Web services are based on syntactic service description. In this paper, a semantic based EAI approach, that allows the uninformed clients to access the services, is introduced. The semantic EAI is designed with the Web services that have semantic service descriptions. The Semantic Web Services(SWS) are described in Web Ontology Language for Services(OWL-S), a semantic service ontology language, and advertised in Universal Description, Discovery and Integration (UDDI). Clients find desired services through the UDDI and get services from service providers through Web Service Description Language(WSDL)

    2000-01-01

    The convergence of telecommunications systems and the Internet causes a variety of concepts for service integration. The focus of the recent research studies and the work of several standardization bodies lies mostly on the interworking of services and the universal service access from end-user systems including both fixed and wireless terminals. All approaches are driven by the concept of providing several technologies to users by keeping the peculiarity of each service alive. But, developments should not only concentrate on media adaptation between VoIP and PSTN, but also consider the adaptation among completely different types of applications as for example E- mail, facsimile, or voice. Unified messaging, which is an already accepted service on the market, provides solutions for conversions of different application protocols into each other. The functionality of converting one medium into another is implemented here in so-called media gateways. This paper provides an overview of the current developments in...

  1. Empirical perspectives on services integration and aging: a review.

    Science.gov (United States)

    Lago, D; Zarit, S H

    1992-01-01

    This article combines a review of social service literature with interviews of key informants on the issue of integrating services for the elderly into human services across the life span. Empirical findings concerning the relative benefits and drawbacks of age-integrated vs. specialized service organizational structures are emphasized. Surprisingly few empirical studies were identified. Instead of empirically based reports, the literature is largely comprised of polemics, which essentially restate long-standing positions on the preferred handling of integration. A persistent difficulty in discussions of federal and state service integration objectives has been the wide differences in definitions of "integration." The lack of data demonstrating that older persons benefit in integrated service systems, along with substantial progress in development of specialized services for the aged, suggest that aging advocates should be cautious in embracing age-integrated service integration proposals. Research within management information systems oriented toward client outcomes is necessary to gain valid knowledge of the merits of various integrated service models.

    During the past decades the various disciplines in planetary sciences have developed to a very high international standard. But the collaboration between the different fields should be improved. To overcome the current fragmentation of the EU Planetary Science community and thereby to increase the scientific return of the related investment, the EU commission is funding via its Framework Program 7 the development of the "Europlanet Research Infrastructure -Europlanet RI". The Europlanet RI will consolidate the integration of the European Planetary Science community which started with Europlanet's FP6 project and will integrate major parts of the related distributed European infrastructure to be shared, fed and expanded by all planetary scientists. This infrastructure encompasses as diverse components as space exploration, ground-based observations, laboratory experiments and numerical modeling teams. Europlanet RI aims at bringing scientists from Europe and beyond together who are working in these fields, support the exchange of experts and ideas and make as many resources and data as possible available to the research community. A central part of Europlanet RI is the "Integrated and Distributed Information Service" or Europlanet-IDIS. The task of IDIS as central part of Europlanet is to provide an easy-to-use Web-based platform to locate teams and laboratories with special knowledge needed to support the own research activities, give access to the wealth of already available data, initiate new research activities needed to interpret accumulated data or to solve open questions, and to exploit synergies between space-based missions and capabilities of ground based observatories. It also offers to a wide range of teams and laboratories the possibility to share their data, advertise their capabilities and increase the scientific return by cooperation. IDIS is organized as an EU FP7 Support Activity, consisting of different access nodes which are connected by

    Full Text Available Abstract A revolutionary feature of emerging media services over the Internet is their ability to account for human perception during service delivery processes, which surely increases their popularity and incomes. In such a situation, it is necessary to understand the users' perception, what should obviously be done using standardized subjective experiences. However, it is also important to develop artificial quality assessors that enable to automatically quantify the perceived quality. This efficiently helps performing optimal network and service management at the core and edges of the delivery systems. In our article, we explore the behavior rating of new emerging artificial speech quality assessors of VoIP calls subject to moderately bursty packet loss processes. The examined Speech Quality Assessment (SQA algorithms are able to estimate speech quality of live VoIP calls at run-time using control information extracted from header content of received packets. They are especially designed to be sensitive to packet loss burstiness. The performance evaluation study is performed using a dedicated set-up software-based SQA framework. It offers a specialized packet killer and includes the implementation of four SQA algorithms. A speech quality database, which covers a wide range of bursty packet loss conditions, has been created and then thoroughly analyzed. Our main findings are the following: (1 all examined automatic bursty-loss aware speech quality assessors achieve a satisfactory correlation under upper (> 20% and lower (< 10% ranges of packet loss processes; (2 they exhibit a clear weakness to assess speech quality under a moderated packet loss process; (3 the accuracy of sequence-by-sequence basis of examined SQA algorithms should be addressed in detail for further precision.

    Full Text Available Background: The aim of health service integration is to provide a sustainable and integrated health system that better meets the needs of the end user. Yet definitions of health service integration, methods for integrating health services and expected outcomes are varied. This review was commissioned by Queensland Health, the government department responsible for health service delivery in Queensland, Australia, to inform efforts to integrate their mental health services. This review reports on the characteristics, reported outcomes, and design quality of studies included in systematic reviews of health service integration research. Method: The review was developed by systematically searching nine electronic databases to find peer-reviewed Australian and international systematic reviews with a focus on health service integration. Reviews were included if they were in the English language and published between 2000 and 2015. A standardised assessment tool was used to analyse the study design quality of included reviews. Data relating to the integration types, methods and reported outcomes of integration were synthesised. Results: Seventeen publications met the inclusion criteria. Eleven (65% reviews were published during the past five years, which may indicate a trend for increased awareness of the need for service integration. The majority of reviews were published by researchers in the UK (8/47%, USA (3/18%, and Australia (3/18%. Included reviews focused on a variety of integration types, including integrated care pathways, governance models, integration of interventions, collaborative/ integrated care models, and integration of different types of healthcare. Most (53% of reviews reported on the cost-effectiveness of service integration, e.g. positive results, no effect, or inconclusive. Only one of the reviews reported on the importance of consumer involvement. The overall design of 70% of the reviews was high, 18% medium, and 12% low

  10. A Novel AP for Improving the Performance of Wireless LANs Supporting VoIP

    Directory of Open Access Journals (Sweden)

    Thavisak Manodham

    2006-08-01

    Full Text Available Recently, wireless LANs based on the IEEE 802.11 standard have become popular and widely used, and Voice-over-IP (VoIP is one of the most promising technologies to be used in mobile devices over wireless networks. Up-to-date, new technologies have improved, providing a high data rate to support various kinds of realtime applications. However, besides the need for higher data rates, seamless handoff is another important issue to be addressed in order to continue supporting real-time services across wireless LANs. In this paper we introduce a novel Access Point (AP with two transceivers to improve network efficiency in terms of supporting seamless handoff and balancing the traffic load in a wireless network. In our proposed scheme, the novel AP will use the second transceiver to scan and find neighboring STAs in the transmission range and later send the result to its associate AP, which in turn compares and analyzes whether or not the STA should perform a handoff. The initial results from our simulations show the novel AP module is more effective than the conventional one in terms of providing a handoff process with low latency and support traffic load sharing with neighbor APs.

    Feldmann, Marius; Janeiro, Jordan; Nestler, Tobias; Hübsch, Gerald; Jugel, Uwe; Preussner, André; Schill, Alexander

    While the implementation of business logic and business processes based on service-oriented architectures is well-understood and covered by existing development approaches, integrated concepts that empower users to exploit the Internet of Services to create complex interactive applications are missing. In this paper, we present an integrated approach that fills this gap. Our approach builds upon service annotations that add meta-information related to user interface generation, service dependencies, and service composition to existing service descriptions. Services can be composed visually to complex interactive applications based on these annotations without the need to write any code. The application code is generated completely from the service composition description. Our approach is able to support heterogeneous target environments ranging from client/server architectures to mobile platforms.

    Full Text Available Business agility remains to be the keyword that drives the business into different directions and enabling a 360 degree shift in the business process. To achieve agility the organization should work on real time information and data. The need to have instant access to information appears to be ever shine requirement of all organizations or enterprise. Access to information does not come directly with a single query but a complex process termed Information integration. Information integration has been in existence for the past two decades and has been progressive up to now. The challenges and issues keep on persisting as information integration problem evolves by itself. This paper addresses the issues in the approaches, techniques and models pertaining to information integration and identifies the problem for a need for a complete model. As SOA is the architectural style that is changing the business patterns today, this paper proposes a service oriented model for information integration. The model mainly focuses on giving a complete structure for information integration that is adaptable to any environment and open in nature. Here information is converted into service and then the information services are integrated through service oriented integration to provide the integrated information also as service.

  2. Voice over Internet protocol for the orthodontic practice: a sensible switch from plain old telephone service.

    Mupparapu, Muralidhar

    2008-03-01

    Voice over Internet protocol (VoIP) is a revolutionary new technology that is causing a stir in the telecommunications industry and threatening the existence of traditional telephone service providers. Based on a simple method of converting analog audio signals into digital data before being transmitted over the Internet, VoIP has gained immense popularity among consumers. The technology is now regarded as an alternative to traditional telephone service for the orthodontic office. When the economics are considered, it is cost-effective, especially for a busy orthodontic practice where the call volumes both in and out are always high. VoIP has the potential to reduce costs, break the barriers between local vs long-distance calling, and make life easier for the office staff. However, deploying VoIP requires a cautious and thought-out process. Users should fully understand the risks and benefits before switching from the public switched telephone network. VoIP customers and service providers are vulnerable to many of the same impersonation-based attacks by those who attempt toll fraud, and identity and information theft. In this article, VoIP is introduced to orthodontic practitioners, who might be unfamiliar with this technology. Internet protocol based private branch exchange systems that are currently marketed as open-source technologies are also reviewed. Additionally, VoIP is compared with the traditional public switched telephone network technology and evaluated for its potential applications in an orthodontic office for both increased efficiency and cost savings.

    Kraetzer, Christian; Dittmann, Jana

    2007-02-01

    Steganography and steganalysis in VoIP applications are important research topics as speech data is an appropriate cover to hide messages or comprehensive documents. In our paper we introduce a Mel-cepstrum based analysis known from speaker and speech recognition to perform a detection of embedded hidden messages. In particular we combine known and established audio steganalysis features with the features derived from Melcepstrum based analysis for an investigation on the improvement of the detection performance. Our main focus considers the application environment of VoIP-steganography scenarios. The evaluation of the enhanced feature space is performed for classical steganographic as well as for watermarking algorithms. With this strategy we show how general forensic approaches can detect information hiding techniques in the field of hidden communication as well as for DRM applications. For the later the detection of the presence of a potential watermark in a specific feature space can lead to new attacks or to a better design of the watermarking pattern. Following that the usefulness of Mel-cepstrum domain based features for detection is discussed in detail.

    The purpose of this study is to estimate the benefits of ecosystem services for prioritization of land use conservation and to highlight the importance of ecosystem services by comparison between ecosystem service value and green GDP accounting. Based on land use pattern and benefit transfer method, this research estimated value of ecosystem services in Taiwan. Scientific information of land use and land cover change is accessed through multi-year satellite imagery moderate resolution imaging spectroradiometer (MODIS), and geographic information system (GIS) technology. Combined with benefit transfer method, this research estimated the ecosystem service valuation of forest, grassland, cropland, wetland, water, and urban for the period of 2000 to 2015 in Taiwan. It is found that forest made the greatest contribution and the significant increasing area of wetland has huge potential benefit for environmental conservation in Taiwan. We recommend placing maintaining wetland ecosystem in Taiwan with higher priority. This research also compared ecosystem service value with natural capital consumption which would essentially facilitate policy makers to understand the relationship between benefits gained from natural capital and the loss from human-made capital.

    André I. Wierdsma

    2009-09-01

    Full Text Available Background: Over recent years, the number of compulsory admissions in many countries has increased, probably as a result of the shift from inpatient to outpatient mental health care. This might be mitigated by formal or collaborative relationships between services. Methods: In a retrospective record linkage study, we compared two neighboring districts, varying in level of service integration. Two periods were combined: 1991–1993 and 2001–2003. We included patients aged 18–60, who had a first emergency compulsory admission (n=830. Their psychiatric history was assessed, and service-use after admission was monitored over a 12-month follow-up. Results: Over a 10-year period, compulsory admission rates increased by 47%. Difference in relative increase between the integrated and non-integrated services was 14%. Patient characteristics showed different profiles in the two districts. Length of stay was >10 days shorter in the integrated district, where the proportion of involuntary readmissions decreased more, and where aftercare was swift and provided to about 10% more patients than in the non-integrated district. Conclusions: Services outcomes showed better results where mental healthcare was more integrated. However, limited effects were found and other factors than integration of services may be more important in preventing compulsory admissions.

    The development of airborne network is conducive to resource sharing, flight management and interoperability in civilian and military aviation fields. To enhance the integrated ability of airborne network, the paper focuses on dynamic network management and service integration architecture for airborne network (DNMSIAN). Adaptive routing based on the mapping mechanism between connection identification and routing identification can provide diversified network access, and ensure the credibility and mobility of the aviation information exchange. Dynamic network management based on trustworthy cluster can ensure dynamic airborne network controllable and safe. Service integration based on semantic web and ontology can meet the customized and diversified needs for aviation information services. The DNMSIAN simulation platform demonstrates that our proposed methods can effectively perform dynamic network management and service integration.

  1. Bringing ecosystem services into integrated water resources management.

    Science.gov (United States)

    Liu, Shuang; Crossman, Neville D; Nolan, Martin; Ghirmay, Hiyoba

    2013-11-15

    In this paper we propose an ecosystem service framework to support integrated water resource management and apply it to the Murray-Darling Basin in Australia. Water resources in the Murray-Darling Basin have been over-allocated for irrigation use with the consequent degradation of freshwater ecosystems. In line with integrated water resource management principles, Australian Government reforms are reducing the amount of water diverted for irrigation to improve ecosystem health. However, limited understanding of the broader benefits and trade-offs associated with reducing irrigation diversions has hampered the planning process supporting this reform. Ecosystem services offer an integrative framework to identify the broader benefits associated with integrated water resource management in the Murray-Darling Basin, thereby providing support for the Government to reform decision-making. We conducted a multi-criteria decision analysis for ranking regional potentials to provide ecosystem services at river basin scale. We surveyed the wider public about their understanding of, and priorities for, managing ecosystem services and then integrated the results with spatially explicit indicators of ecosystem service provision. The preliminary results of this work identified the sub-catchments with the greatest potential synergies and trade-offs of ecosystem service provision under the integrated water resources management reform process. With future development, our framework could be used as a decision support tool by those grappling with the challenge of the sustainable allocation of water between irrigation and the environment.

  2. ON INTEGRATION AND ADAPTATION IN COMPLEX SERVICE SYSTEMS

    The services sector employs a large and growing proportion of workers in the industrialized nations,and it is increasingly dependent on information and communication technologies. While the interdependences, similarities and complementarities of manufacturing and services are significant, there are considerable differences between goods and services, including the shift in focus from mass production to mass customization (whereby a service is produced and delivered in response to a customer's stated or imputed needs). In general, services can be considered to be knowledge-intensive agents or components which work together as providers and consumers to create or co-produce value. Like manufacturing systems, an efficient service system must be an integrated system of systems, leading to greater connectivity and interdependence. Integration must occur over the physical, temporal, organizational and functional dimensions, and must include methods concerned with the component, the management, and the system. Moreover, an effective service system must also be an adaptable system, leading to greater value and responsiveness. Adaptation must occur over the dimensions of monitoring, feedback, cybernetics and learning, and must include methods concerned with space, time, and system. In sum, service systems are indeed complex, especially due to the uncertainties associated with the human-centered aspects of such systems. Moreover, the system complexities can only be dealt with methods that enhance system integration and adaptation. The paper concludes with several insights, including a plea to shift the current misplaced focus on developing a science or discipline for services to further developing a systems engineering approach to services, an approach based on the integration and adaptation of a host of sciences or disciplines (e.g., physics, mathematics, statistics, psychology, sociology, etc.). In fact, what is required is a services-related transdisciplinary - beyond a

    Virtual data integration provides a coherent interface for querying heterogeneous data sources (e.g., web services, proprietary systems) with minimum upfront effort. Still, this requires its users to learn the query language and to get acquainted with data organization, which may pose problems even to proficient users. We present a keyword search system, which proposes a ranked list of structured queries along with their explanations. It operates mainly on the metadata, such as the constraints on inputs accepted by services. It was developed as an integral part of the CMS data discovery service, and is currently available as open source.

    The security is crucial for any system nowadays, especially communications. One of the most successful protocols in the field of communication over IP networks is Session Initiation Protocol. It is an open-source project used by different kinds of applications, both open-source and proprietary. High penetration and text-based principle made SIP number one target in IP telephony infrastructure, so security of SIP server is essential. To keep up with hackers and to detect potential malicious attacks, security administrator needs to monitor and evaluate SIP traffic in the network. But monitoring and following evaluation could easily overwhelm the security administrator in networks, typically in networks with a number of SIP servers, users and logically or geographically separated networks. The proposed solution lies in automatic attack detection systems. The article covers detection of VoIP attacks through a distributed network of nodes. Then the gathered data analyze aggregation server with artificial neural network. Artificial neural network means multilayer perceptron network trained with a set of collected attacks. Attack data could also be preprocessed and verified with a self-organizing map. The source data is detected by distributed network of detection nodes. Each node contains a honeypot application and traffic monitoring mechanism. Aggregation of data from each node creates an input for neural networks. The automatic classification on a centralized server with low false positive detection reduce the cost of attack detection resources. The detection system uses modular design for easy deployment in final infrastructure. The centralized server collects and process detected traffic. It also maintains all detection nodes.

    2004-01-01

    Enterprise Application Integration (EAI) would be linking diverse systems and applications across the enterprise to enable the enterprise IT systems to adapt to the dynamic business environment and automate any business practices.Whereas, with traditional EAI solution, it is difficult to efficiently link the different proprietary applications and data sources, and difficult to enable the system to rapidly identify and respond to changes in the dynamic business environment. In order to solve these problems, this paper uses the Web Services technology for EAI. This paper discusses the traditional EAI technologies and the bottlenecks for applications integration, also elaborates the Web Services technology and the advantages suited for applications integration. Therefore, the model of EAI with Web Services (EAIWS) is proposed to efficiently implement the integration of diverse applications and systems within or between the enterprises. With EAIWS, this paper provides an example to show how the application system works. This paper also discusses the advantages of EAIWS.

    2016-08-01

    A large development of downstream services is expected to be stimulated starting from earth observations (EO) datasets acquired by Copernicus satellites. An important challenge connected with the availability of downstream services is the possibility for their integration in order to create innovative applications with added values for users of different categories level. At the moment, the world of geo-information (GI) is extremely heterogeneous in terms of standards and formats used, thus preventing a facilitated access and integration of downstream services. Indeed, different users and data providers have also different requirements in terms of communication protocols and technology advancement. In recent years, many important programs and initiatives have tried to address this issue even on trans-regional and international level (e.g. INSPIRE Directive, GEOSS, Eye on Earth and SEIS). However, a lack of interoperability between systems and services still exists. In order to facilitate the interaction between different downstream services, a new architectural approach (developed within the European project ENERGIC OD) is proposed in this paper. The brokering-oriented architecture introduces a new mediation layer (the Virtual Hub) which works as an intermediary to bridge the gaps linked to interoperability issues. This intermediation layer de-couples the server and the client allowing a facilitated access to multiple downstream services and also Open Data provided by national and local SDIs. In particular, in this paper an application is presented integrating four services on the topic of agriculture: (i) the service given by Space4Agri (providing services based on MODIS and Landsat data); (ii) Gicarus Lab (providing sample services based on Landsat datasets) and (iii) FRESHMON (providing sample services for water quality) and services from a several regional SDIs.

    Full Text Available Abstract Background Bioinformatics is commonly featured as a well assorted list of available web resources. Although diversity of services is positive in general, the proliferation of tools, their dispersion and heterogeneity complicate the integrated exploitation of such data processing capacity. Results To facilitate the construction of software clients and make integrated use of this variety of tools, we present a modular programmatic application interface (MAPI that provides the necessary functionality for uniform representation of Web Services metadata descriptors including their management and invocation protocols of the services which they represent. This document describes the main functionality of the framework and how it can be used to facilitate the deployment of new software under a unified structure of bioinformatics Web Services. A notable feature of MAPI is the modular organization of the functionality into different modules associated with specific tasks. This means that only the modules needed for the client have to be installed, and that the module functionality can be extended without the need for re-writing the software client. Conclusions The potential utility and versatility of the software library has been demonstrated by the implementation of several currently available clients that cover different aspects of integrated data processing, ranging from service discovery to service invocation with advanced features such as workflows composition and asynchronous services calls to multiple types of Web Services including those registered in repositories (e.g. GRID-based, SOAP, BioMOBY, R-bioconductor, and others.

    2007-12-01

    Full Text Available Introduction: Integration has been advanced as a strategy for the delivery of a number of human services that have traditionally been delivered by autonomous agencies with independent processes and funding sources. However, measurement of the dimensions of integration has been hampered by numerous factors, including a lack of definitional and conceptual clarity of integration, and the use of measurement tools with atheoretical foundations and limited psychometric testing. Theory/methods: Based on a review of integration measurement approaches, a comprehensive approach to the measure of multiple dimensions of integrated human service networks was conceptualized. The combination of concepts was derived from existing theoretical, policy, and measurement approaches in order to establish the content validity and comprehensiveness of the proposed measure. Results: The dimensions of human service integration measures are: (1 Observed (current and expected structural inputs, or the mix of agencies that comprise the network (e.g. extent, scope, depth, congruence within an agency, and reciprocity between agencies. (2 Functioning of the network both in terms of the quality of the network or partnership functioning and ingredients of the integration of the networks' working arrangements and range of human services provided. (3 Network outputs in terms of network capacity (e.g. what is accomplished, for how many and how quickly given the local demand measured from dual perspectives of the agency and the family. Conclusion: This newly developed measure unites multiple perspectives in a comprehensive approach to the measurement of integration of human service networks. Content validity has been established. Future work should focus on further refinement of this instrument through psychometric evaluation (e.g. construct validity in diverse networks and relating these measures of network integration to client and system outcomes.

    Full Text Available In recent years information integration became significant problem for both natural and legal persons in everyday operations. Huge amount of information are available, but insufficiently processed in order to have useful value. Choosing the right combination of tools and technologies for integration is prerequisite for requiring information from multiple heterogeneous sources and their qualitative and simple using after.In this paper, we have focused on information integration within companies which are parts of supply chain or network. This environment typically includes a various mix of sources, structured (such as relational or other databases, and unstructured (such as document repositories, spreadsheets, documents, web pages, emails and others. Effective information integration and sharing significantly enhances supply chain practices. Service oriented architecture (SOA is an architectural style for building software applications that use services available in a network such as the web. The use of SOA to achieve inter-enterprise supply network information integration has many advantages.

As the long-term evolution (LTE of universal terrestrial radio access network (UTRAN, evolved UTRAN (E-UTRAN is the first OFDMA-based packet radio network and thus selected in this paper as an application example. Our proposed physical downlink control channel (PDCCH resource allocation approach for E-UTRAN is composed of bidirectional power control, inner loop link adaptation (ILLA, and outer loop link adaptation (OLLA algorithms. Its effectiveness is validated through large-scale radio system level simulations, and simulation results confirm that VoIP capacity with dynamic scheduling can be further enhanced with this PDCCH resource allocation approach. Moreover, the VoIP performance requirements for international mobile telecommunications-advanced (IMT-Advanced radio interface technologies can be met with dynamic scheduling together with proposed PDCCH resource allocation. Besides E-UTRAN, this approach can be introduced to other OFDMA-based mobile communication systems for VoIP performance enhancement as well.

    In Tanzania, reproductive health and HIV services are coordinated by the Ministry of Health and Social Welfare in two separate units namely Reproductive and Child Health Section and the National AIDS Control Programme. The importance of integrating the two services that are vertically run is expected to improve access to and uptake of key essential services and extend coverage to underserved and vulnerable populations and thus minimizing missed opportunities. Experts around the world recognize the central role of Sexual and Reproductive Health (SRH) services in preventing HIV infection. Evidence suggests that improving access to contraception for women to prevent pregnancy is an important and cost-effective way to prevent HIV-positive births. Integrating SRH and HlV services therefore verifies its importance for improving maternal and child health as well as leading to prevention of HIV infection. The primary objective of this review was to gain an understanding of the current linkages between SRH and HIV within Tanzania's policies, programmes, systems and services. Policy documents, guidelines, national laws, and published reports on SRH and HIV were reviewed. The majority of the reviewed documents mentioned fundamentals of integration between SRH and HIV. Majority of policies and guidelines both in family planning (FP) and HIV documents mandate bi-directional linkages. This review suggests that there are linkages between the two services and can be operationalised together. However, policies and guidelines only specify services to be integrated without due consideration of resources and structural orientation for linked services.

The aim of the framework is to provide tracing of RFID tagged physical items among or within various libraries. Using SELIDA we are able to integrate typical library services—such as checking in or out items at different libraries with different Integrated Library Systems—without requiring substantial changes, code-wise, in their structural parts. To do so, we employ the Object Naming Service mechanism that allows us to retrieve and process information from the Electronic Product Code of an item and its associated services through the use of distributed mapping servers. We present two use case scenarios involving the Koha open source ILS and we briefly discuss the potential of this framework in supporting bibliographic Linked Data.

    2015-01-01

    AIM: To characterize the patients utilizing a gastroenterology behavioral medicine service and examine the effect of treatment on health care utilization. METHODS: Patients were referred by their gastroenterologists for psychological treatment during a 15 mo period. Patients seen for an intake with a psychologist completed the Brief Symptom Inventory (BSI) and a checklist of psychosocial concerns. A subset of patients with functional bowel disorders also completed a disease specific quality of life measure. Chart review was conducted to obtain information on type and frequency of sessions with the psychologist, the number of outpatient gastroenterology visits, and number of gastroenterology-related medical procedures during the 6 mo following psychological intake. RESULTS: Of 259 patients referred for treatment, 118 (46%) completed an intake with a psychologist. Diagnoses included: irritable bowel syndrome (42%), functional dyspepsia (20%), inflammatory bowel diseases (20%), esophageal symptoms (10%), and “other” (8%). Demographic variables and disease type did not differentiate between those who did and did not schedule an intake. Mean t-scores for the BSI global score index and the depression, anxiety, and somatization subscales fell below the cutoff for clinical significance (t = 63). Treatments were predominantly gut-directed hypnosis (48%) and cognitive behavioral therapy (44%). Average length of treatment was 4 sessions. Among functional gastrointestinal (GI) patients, those patients who initiated treatment received significantly fewer GI-related medical procedures during the 6 mo following the referral than patients who did not schedule an intake [t (197) = 2.69, P < 0.01]. CONCLUSION: Patients are receptive to psychological interventions for GI conditions and there is preliminary evidence that treatment can decrease health-care utilization among patients with functional GI conditions.

    Data are central to scientific research and practices. The advance of experiment methods and information retrieval technologies leads to explosive growth of scientific data and databases. However, due to the heterogeneous problems in data formats, structures and semantics, it is hard to integrate the diversified data that grow explosively and analyse them comprehensively. As more and more public databases are accessible through standard protocols like programmable interfaces and Web portals, Web-based data integration becomes a major trend to manage and synthesise data that are stored in distributed locations. Mashup, a Web 2.0 technique, presents a new way to compose content and software from multiple resources. The paper proposes a layered framework for integrating pharmacogenomics data in a service-oriented approach using the mashup technology. The framework separates the integration concerns from three perspectives including data, process and Web-based user interface. Each layer encapsulates the heterogeneous issues of one aspect. To facilitate the mapping and convergence of data, the ontology mechanism is introduced to provide consistent conceptual models across different databases and experiment platforms. To support user-interactive and iterative service orchestration, a context model is defined to capture information of users, tasks and services, which can be used for service selection and recommendation during a dynamic service composition process. A prototype system is implemented and cases studies are presented to illustrate the promising capabilities of the proposed approach.

    It is widely recognized that exchange, distribution, and integration of biological data are the keys to improve bioinformatics and genome biology in post-genomic era. However, the problem of exchanging and integrating biological data is not solved satisfactorily. The eXtensible Markup Language (XML) is rapidly spreading as an emerging standard for structuring documents to exchange and integrate data on the World Wide Web (WWW). Web service is the next generation of WWW and is founded upon the open standards of W3C (World Wide Web Consortium)and IETF (Internet Engineering Task Force). This paper presents XML and Web Services technologies and their use for an appropriate solution to the problem of bioinformatics data exchange and integration.

  10. Can Collaboration Provide Integrated Services for Prisoners in Norway?

    Directory of Open Access Journals (Sweden)

    Gunnar Vold Hansen

    2015-12-01

    Full Text Available In this article, my contention is that Norway's criminal justice policy is increasingly based on principles taken from positive criminology. This means that the correctional service places strong emphasis on establishing collaboration with the local authorities (the municipalities in order to offer convicted persons integrated services, both during and after serving their sentences. I also point out that positive criminology's principle of viewing convicted persons as unique individuals with individual problems and resources – problems to which there are rarely clear-cut solutions – means that these problems are perceived as 'wicked problems'. A recommended approach to 'wicked problems' is to establish collaboration between the different service providers involved. The article describes the experiences gained from a pilot project that entailed offering a training programme to convicted persons with substance abuse problems. One of the goals of the project was to link the programme to an offer of integrated services after the sentence had been served. The experiences described in semi-structured interviews with 16 convicted persons, seven correctional service employees and three local authority employees was that it was difficult to put in place such an integrated service package. On this basis, I discuss the reasons why it was so difficult to achieve the desired collaboration, and I outline some proposals for how these challenges can be resolved in future.

  3. Multidisciplinary management--an opportunity for service integration.

    Science.gov (United States)

    Cameron, M

    1997-01-01

    The management team of the future will enter an environment requiring facilitation, participation, clinical, and empowerment skills. Those individuals who possess a clinical orientation as well as business expertise will be sought to manage multidisciplinary units. The rapid changes in the health-care environment have forced organizations to restructure their operations. To achieve quality care, customer satisfaction, cost-effectiveness, and efficiency, service integration across the organization will be required. As we approach the 21st century, this standard will evolve until "all levels are managing patient care." Some of the restructuring trends occurring in the health-care industry have been collaboration service integration, management consolidation, and job elimination. The emphasis for the multidisciplinary manager of the future will include integrating the professional and clinical services, managing information, building community partnerships, promoting physician collaboration, and managing the change process. A model organization in the next century will move toward a people-oriented system with inclusion and empowerment initiatives. Service integration will affect all organizations, but the disciplines within the Clinical Support System will be the most affected. Future opportunities of leadership will exist for pathologists, nurses, or medical technologists as the professional silos of managers and clinicians continue to crumble.

    Taylor, Susan L; Leffers, Jeanne M

    The aim of the research is to review all qualitative research studies related to service-learning assessment in nursing education. Recent literature reviews have examined quantitative but not qualitative research studies on service-learning assessment in nursing education. An integrative review analyzed the results of published qualitative research of service-learning assessment. Articles included in this review were published in English in peer-reviewed journals from 1997 to 2014 and encompassed information on outcomes, assessment or evaluation, nursing education, and service-learning. Nine articles containing thematic analysis were included in the final review. Findings were synthesized into a higher order of analysis. Eight categories from that analysis were created: professional competency development, integration of knowledge for the professional nursing role, greater understanding of community strengths and needs, collaboration and teamwork, transformation and personal growth, civic engagement, emotions and adjustment, and culture awareness and competency. The integrative review will aid in the development of measurement categories for further nursing service-learning assessment work.

    In a global business context with continuous changes, the enterprises have to enhance their operational efficiency, to react more quickly, to ensure the flexibility of their business processes, and to build new collaboration pathways with external partners. To achieve this goal, they must use e-business methods, mechanisms and techniques while capitalizing on the potential of new information and communication technologies. In this context, we propose a standards, model and Web services-based approach for modeling and integrating agile enterprise business processes. The purpose is to benefit from Web services characteristics to enhance the processes design and realize their dynamic integration. The choice of focusing on Web services is essentially justified by their broad adoption by enterprises as well as their capability to warranty interoperability between both intra and inter-enterprises systems. Thereby, we propose in this chapter a metamodel for describing business processes, and discuss their dynamic in...

  8. A Service Portal for the Integrated SCaN Network

    Marx, Sarah R.

    2012-01-01

    The Space Communication and Navigation (SCaN) program office owns the assets and services provided by the Deep Space Network (DSN), Near Earth Network (NEN), and Space Network (SN). At present, these individual networks are operated by different NASA centers--JPL for DSN--and Goddard Space Flight Center (GSFC) for NEN and SN--with separate commitments offices for each center. In the near future, SCaN's program office would like to deploy an integrated service portal which would merge the two commitments offices with the goal of easing the task of user planning for space missions requiring services of two or more of these networks. Following interviews with subject matter experts in this field, use cases were created to include the services and functionality mission users would like to see in this new integrated service portal. These use cases provide a guideline for a mock-up of the design of the user interface for the portal. The benefit of this work will ease the time required and streamline/standardize the process for planning and scheduling SCAN's services for future space missions.

    2014-09-01

    The need to integrate TB/HIV control programmes has become critical due to the comorbidity regarding these diseases and the need to optimise the use of resources. In developing countries such as Ghana, where public health interventions depend on donor funds, the integration of the two programmes has become more urgent. This paper explores stakeholders' views on the integration of TB/HIV control programmes in Ghana within the remits of contingency theory. With 31 purposively selected informants from four regions, semi-structured interviews and observations were conducted between March and May 2012, and the data collected were analysed using the inductive approach. The results showed both support for and opposition to integration, as well as some of the avoidable challenges inherent in combining TB/HIV control. While those who supported integration based their arguments on clinical synergies and the need to promote the efficient use of resources, those who opposed integration cited the potential increase in workload, the clinical complications associated with joint management, the potential for a leadership crisis, and the "smaller the better" propositions to support their stance. Although a policy on TB/HIV integration exists, inadequate 'political will' from the top management of both programmes has trickled down to lower levels, which has stifled progress towards the comprehensive management of TB/HIV and particularly leading to weak data collection and management structures and unsatisfactory administration of co-trimoxazole for co-infected patients. It is our view that the leadership of both programmes show an increased commitment to protocols involving the integration of TB/HIV, followed by a commitment to addressing the 'fears' of frontline service providers to encourage confidence in the process of service integration.

    2014-03-29

    Based on practices in commercial organizations and public services, healthcare organizations are using service charters to inform patients about the quality of service they can expect and to increase patient-centeredness. In the Netherlands, an integrated regional stroke service involving five organizations has developed and implemented a single service charter. The purpose of this study is to determine the organizational enablers for the effective development and implementation of this service charter. We have conducted an exploratory qualitative study using Grounded Theory to determine the organizational enablers of charter development and implementation. Individual semi-structured interviews were held with all members of the steering committee and the taskforce responsible for the service charter. In these twelve interviews, participants were retrospectively asked for their opinions of the enablers. Interview transcripts have been analysed using Glaser's approach of substantive coding consisting of open and selective coding in order to develop a framework of these enablers. A tabula rasa approach was used without any preconceived frameworks used in the coding process. We have determined seven categories of enablers formed of a total of 27 properties. The categories address a broad spectrum of enablers dealing with the basic foundations for cooperation, the way to manage the project's organization and the way to implement the service charter. In addition to the enablers within each individual organization, enablers that reflect the whole chain seem to be important for the effective development and implementation of this service charter. Strategic alignment of goals within the chain, trust between organizations, willingness to cooperate and the extent of process integration are all important properties. This first exploratory study into the enablers of the effective development and implementation was based on a single case study in the Netherlands. This is the

    2009-10-01

    Full Text Available Voice data packets have to arrive at the destination in time, with a defined cadence and with low and constant delay in order to allow the real time voice reconstruction. From this point of view, transmitting voice over IP networks is the most sensitive category of applications, especially when wireless medium is involved. The paper discusses the possibilities of transmitting the maximum number of simultaneous voice streams over 802.11 wireless networks considering the main factors which impact with VoIP throughput, in a basic scenario. Starting from a proposed communication model, the number of simultaneous possible VoIP sessions is calculated, taking into consideration the contribution of the protocol overheads, the security overheads, the PHY level timings and the CODEC proprieties. Numerical results are generated and compared.

    Directory of Open Access Journals (Sweden)

    Elizabeth England

    2005-10-01

    Full Text Available Purpose: The purpose of this paper is to examine the effects of health care policy on the development of integrated mental health services in England. Data sources: Drawing largely from a narrative review of the literature on adult mental health services published between January 1997 and February 2003 undertaken by the authors, we discuss three case studies of integrated care within primary care, secondary care and across the primary/secondary interface for people with serious mental illness. Conclusion: We suggest that while the central thrust of a raft of recent Government policies in England has been towards integration of different parts of the health care system, policy waterfalls and implementation failures, the adoption of ideas before they have been thoroughly tried and tested, a lack of clarity over roles and responsibilities and poor communication have led to an integration rhetoric/reality gap in practice. This has particular implications for people with serious mental health problems. Discussion: We conclude with suggestions for strategies that may facilitate more integrated working.

  19. Integrating reproductive health services into family planning programs.

    Science.gov (United States)

    1995-06-01

    A recent Population Council publication, Reproductive Health Approach to Family Planning, discusses integration of reproductive health into family planning programs in a series of edited presentations that Council staff and colleagues gave at a 1994 meeting of the US Agency for International Development (USAID) cooperating agencies. The presentations reflect the Council's view that family planning programs ought to help individuals achieve their own reproductive goals in a healthful manner. The report discusses four areas of reproductive health: reproductive tract infections (RTIs), including sexually transmitted diseases; prevention and treatment of unsafe abortion; pregnancy, labor, and delivery care; and postpartum care. Christopher Elias (Senior Associate, Programs Division) argued that family planning programs ought to provide services that target RTIs, given that these illnesses afflict a significant proportion of reproductive-age women. The family planning community has an ethical responsibility to provide services to women who experience an unwanted pregnancy. They must have access to high-quality postabortion care, including family planning services. Professional midwives are ideally suited to serve as integrated reproductive health workers trained to combat the five major maternal killers: hemorrhage, sepsis, pregnancy-induced hypertension, obstructed labor, and unsafe abortion. This was demonstrated in a highly successful Life-Saving Skills for Midwives program undertaken in Ghana, Nigeria, and Uganda, and soon to start in Vietnam in conjunction with the Council's Safe Motherhood research program. Family planning services should be viewed as part of a comprehensive set of health services needed by postpartum women, which include appropriate contraception, maternal health checks, well-baby care, and information about breastfeeding, infant care, and nutrition. Family planning programs should incorporate breastfeeding counseling into their services. When

  20. The Design of VoIP Systems With High Perceptual Conversational Quality

    Benjamin W. Wah

    2009-04-01

    Full Text Available This paper describes our work on real-time two-party and multi-party VoIP (voice-over-IP systems that can achieve high perceptual conversational quality. It focuses on the fundamental understanding of conversational quality and its trade-offs among the design of speech codecs and strategies for network control, playout scheduling, and loss concealments. We have studied three key aspects that address the limitations of existing work and improve the perceptual quality of VoIP systems. Firstly, we have developed a statistical approach based on just-noticeable difference (JND to significantly reduce the large number of subjective tests, as well as a classification method to automatically learn and generalize the results to unseen conditions. Using network and conversational conditions measured at run time, the classifier learned helps adjust the control algorithms in achieving high perceptual conversational quality. Secondly, we have designed a cross-layer speech codec to interface with the loss-concealment and playout scheduling algorithms in the packet-stream layer in order to be more robust and effective against packet losses. Thirdly, we have developed a distributed algorithm for equalizing mutual silences and an overlay network for multi-party VoIP systems. The approach leads to multi-party conversations with high listening only speech quality and balanced mutual silences.

  1. An Optimization Technique for Improved VoIP Performance over Wireless LAN

    Directory of Open Access Journals (Sweden)

    Tamal Chakraborty

    2012-03-01

    Full Text Available The performance of wireless LANs is greatly affected by pathloss, RF interference and other sources of signal attenuation, in addition to network congestion. The primary factors involved in effective real-time communication, namely delay and loss, must be within certain controlled limits in such a scenario. In this paper, we analyze the various factors driving IEEE 802.11b access points through extensive simulations and thereafter develop an optimization technique to configure the parameters of the access points. We simulate our test bed scenario and apply the developed algorithm. We then implement the configured parameters in our SIP enabled test bed to provide optimum Voice over IP (VoIP performance. Thereafter, we further analyze and optimize the parameters of the communicating nodes being realized through Xlite soft phones that enhance VoIP performance to a much better extent both for voice and video calls. Test bed results confirm an improvement from 22% packet loss to 3% considering both AP and node configurations together. Finally, we propose optimization algorithm for proper selection of threshold parameters in active queue management system. Results verify significant performance improvement in VoIP under congested scenarios. Simulation and measured results have also been included.

  3. Mainstreaming Natural Capital into Decisions: Integrated Valuation of Ecosystem Services

    Directory of Open Access Journals (Sweden)

    Arnas Palaima

    2013-08-01

    Full Text Available The purpose of the article is to review current paradigms in ecosystem services valuation, existing gaps and current trends in addressing those gaps. Natural capital, often defined as the stock of natural ecosystems that yields a flow of valuable ecosystem goods or services into the future, is often undervalued or not valued at all by governments, business and society, which leads to environmental degradation and loss of biodiversity. One of the major reasons of such undervaluation is the lack of practical, realistic quantitative methods/models that would establish ecosystem services value and its change due to human development. A promising, recently developed ecosystem services modeling system is InVEST: “Integrated Valuation of Ecosystem Services and Trade-Offs.” InVEST is a set of Geographic Information Systems (GIS models that predict the provision and value of ecosystem services and habitat provision given land use/land cover maps and related biophysical, economic, and institutional data for the study region. InVEST, if further developed and applied in a systematic way, could facilitate mainstreaming the natural capital into decisions at all levels and provide a strong foundation for local natural resources managers to improve and optimize their environmental management strategies.

    1997-12-01

    Increasingly, the public and private sectors are turning to "service integration" efforts to reduce, if not eliminate, barriers to needed care created by categorical programs. In 1991, the Robert Wood Johnson Foundation established a new national demonstration project, called the Child Health Initiative, intended to test the feasibility of developing mechanisms at the community level to coordinate the delivery of health services and to pay for those services through a flexible pool of previously categorical funds. This article presents the findings of an independent evaluation of the Child Health Initiative. The evaluation utilized a combination of qualitative methods to assess and describe the experiences of the communities as they developed and implemented integrated health services. It used a repeated measures design involving two site visits and interim telephone interviews, as well as review of documents. Overall, the demonstration project achieved mixed success. Both care coordination and the production of community health report cards were found to be achievable within the relatively short life of the foundation grant. However, many sites experienced significant delays in the production of report cards and implementing care coordination plans because the sites largely did not benefit from the successful models already in existence. Little clear progress was made in implementing the decategorization component of the project. Sites experienced difficulties due to lack of previous experience with this new undertaking, the inability to secure active cooperation from local, state, and federal agencies, the relatively short duration of the project, and other factors. A number of lessons were learned from this project that may be useful in future decategorization experiments, including (1) a clear understanding of the concept and its applications among all parties is essential, (2) high-level political commitments to the effort are needed between all levels of

    Full Text Available This paper describes the state of the art of a simplified model for integration of services in mega events. The project context, which was financed by the National Research Council – CNPq, is divided into six major areas or functional groups: Urban Mobility, Tourism, Airports, Security, Energy and Telecommunications. The proposal is described in layers, as an infrastructure model of integration and services evaluation, describing its main layers and interaction processes. The proposal described in this paper is restricted to the telecommunication subproject, however, in the modeling of the scenario for the study case, it was necessary to considerate requirements and variables that are common to all subprojects. In the specification process of these requirements, we noticed important processes that interact with some sectors in the city of São Paulo, however, in the mean time, we noticed some failures regarding the integration and collaboration performed by administrators elements of stadiums as main focus in the mega event and part of our case study. Currently, the proposal is in its first version as open software for the evaluation of the services quality and the mega event infrastructure through the use of performance indicators.

    The traditional organizational boundaries between healthcare, social work, police and other non-profit organizations are fading and being replaced by new relational patterns among a variety of disciplines. Professionals work from their own history, role, values and relationships. It is often unclear who is responsible for what because this new network structure requires rules and procedures to be re-interpreted and re-negotiated. A new moral climate needs to be developed, particularly in the early stages of integrated services. Who should do what, with whom and why? Departing from a relational and hermeneutic perspective, this article shows that professionals in integrated service networks embark upon a moral learning process when starting to work together for the client's benefit. In this context, instrumental ways of thinking about responsibilities are actually counterproductive. Instead, professionals need to find out who they are in relation to other professionals, what core values they share and what responsibilities derive from these aspects. This article demonstrates moral learning by examining the case of an integrated social service network. The network's development and implementation were supported by responsive evaluation, enriched by insights of care ethics and hermeneutic ethics.

    Giving the patient full control over his medical data electronically remains one of the most discussed topics in healthcare today. The INFOPAT project in the Rhine-Neckar region focuses on a personal cross-enterprise electronic health record (PEHR) in which the patient plays a major role. Thus, he should be provided with the possibility of granting access to his medical data which could be realized using a consent creator service. This paper presents a user interface concept for such a service as well as aspects for the technical implementation. In addition, a pattern for integrating the service into an existing IHE based infrastructure is shown. These concepts could be further adapted for improving patient empowerment in health care projects.

    One of the current major challenges in scientific modeling and simulation, in particular in the infrastructure-analysis community, is the development of techniques for efficiently and automatically coupling disparate tools that exist in separate locations on different platforms, implemented in a variety of languages and designed to be standalone. Recent advances in web-based platforms for integrating systems such as SOA provide an opportunity to address these challenges in a systematic fashion. This paper describes Hydra, an integrating architecture for infrastructure modeling and simulation that defines geography-based schemas that, when used to wrap existing tools as web services, allow for seamless plug-and-play composability. Existing users of these tools can enhance the value of their analysis by assessing how the simulations of one tool impact the behavior of another tool and can automate existing ad hoc processes and work flows for integrating tools together.

  10. Integrated services to the home and small business over a service-independent HFC network

    1995-11-01

    This paper proposes three different approaches to providing integrated digital services to small businesses and residential customers over modern hybrid fiber and coaxial (HFC) access networks. The target delivery system is one that is flexible and forms a multiservice, service- independent platform capable of providing a wide range of services (voice, video, data, and multimedia). The merits and limitations of the three approaches are explored. In the first approach, the common facilities of an HFC access network may be shared by the frequency partitioning of the coaxial plant's radio frequency spectrum. video, data, and telephony services each use different portions of this spectrum -- a service-dependent network. In the second approach, asynchronous transfer mode (ATM) transmission is used as the information delivery vehicle all the way to the home or small business, creating a more flexible delivery system. The ATM-based architecture is expected to support any service or service mix -- a service-independent network. In the third approach, a common transport protocol composed of both asynchronous and synchronous transfer modes (ATM/STM) is used. Such an approach could (1) provide a common interface between home/small business premises equipment and both the circuit and ATM switching networks; (2) meet a wide range of delay and throughput requirements; and (3) allow for many network migration scenarios.

    The UK Government is formally committed to reducing carbon emissions and protecting and improving natural capital and the environment. However, actually delivering on these objectives requires an integrated approach to addressing two parallel challenges: de-carbonising future energy system pathways; and safeguarding natural capital to ensure the continued flow of ecosystem services. Although both emphasise benefiting from natural resources, efforts to connect natural capital and energy systems research have been limited, meaning opportunities to improve management of natural resources and meet society's energy needs could be missed. The ecosystem services paradigm provides a consistent conceptual framework that applies in multiple disciplines across the natural and economic sciences, and facilitates collaboration between them. At the forefront of the field, integrated ecosystem service - economy models have guided public- and private-sector decision making at all levels. Models vary in sophistication from simple spreadsheet tools to complex software packages integrating biophysical, GIS and economic models and draw upon many fields, including ecology, hydrology, geography, systems theory, economics and the social sciences. They also differ in their ability to value changes in natural capital and ecosystem services at various spatial and temporal scales. Despite these differences, current models share a common feature: their treatment of energy systems is superficial at best. In contrast, energy systems research has no widely adopted, unifying conceptual framework that organises thinking about key system components and interactions. Instead, the literature is organised around modelling approaches, including life cycle analyses, econometric investigations, linear programming and computable general equilibrium models. However, some consistencies do emerge. First, often contain a linear set of steps, from exploration to resource supply, fuel processing, conversion

    Susannah H Mayhew

    Full Text Available The body of knowledge on evaluating complex interventions for integrated healthcare lacks both common definitions of 'integrated service delivery' and standard measures of impact. Using multiple data sources in combination with statistical modelling the aim of this study is to develop a measure of HIV-reproductive health (HIV-RH service integration that can be used to assess the degree of service integration, and the degree to which integration may have health benefits to clients, or reduce service costs.Data were drawn from the Integra Initiative's client flow (8,263 clients in Swaziland and 25,539 in Kenya and costing tools implemented between 2008-2012 in 40 clinics providing RH services in Kenya and Swaziland. We used latent variable measurement models to derive dimensions of HIV-RH integration using these data, which quantified the extent and type of integration between HIV and RH services in Kenya and Swaziland. The modelling produced two clear and uncorrelated dimensions of integration at facility level leading to the development of two sub-indexes: a Structural Integration Index (integrated physical and human resource infrastructure and a Functional Integration Index (integrated delivery of services to clients. The findings highlight the importance of multi-dimensional assessments of integration, suggesting that structural integration is not sufficient to achieve the integrated delivery of care to clients--i.e. "functional integration".These Indexes are an important methodological contribution for evaluating complex multi-service interventions. They help address the need to broaden traditional evaluations of integrated HIV-RH care through the incorporation of a functional integration measure, to avoid misleading conclusions on its 'impact' on health outcomes. This is particularly important for decision-makers seeking to promote integration in resource constrained environments.

  16. Seamless Integration of RESTful Services into the Web of Data

    2012-01-01

    Full Text Available We live in an era of ever-increasing abundance of data. To cope with the information overload we suffer from every single day, more sophisticated methods are required to access, manipulate, and analyze these humongous amounts of data. By embracing the heterogeneity, which is unavoidable at such a scale, and accepting the fact that the data quality and meaning are fuzzy, more adaptable, flexible, and extensible systems can be built. RESTful services combined with Semantic Web technologies could prove to be a viable path to achieve that. Their combination allows data integration on an unprecedented scale and solves some of the problems Web developers are continuously struggling with. This paper introduces a novel approach to create machine-readable descriptions for RESTful services as a first step towards this ambitious goal. It also shows how these descriptions along with an algorithm to translate SPARQL queries to HTTP requests can be used to integrate RESTful services into a global read-write Web of Data.

  17. Interconnected operations services in a vertically integrated utility

    Energy Technology Data Exchange (ETDEWEB)

    Hoffman, S.P. [ComEd, Lombard, IL (United States)

    1999-11-01

    The North American electric industry has historically been composed of regulated Vertically Integrated Utilities (VIU). Vertical integration means that the same company owns generation, transmission, and distribution facilities. Regulated utilities were ensured cost recovery for all justifiable expenses. The entire industry is in the process of deregulation. The industry-wide trend is to competitive generation, while transmission and distribution remain regulated. Many variations, in both timing and structure, exist in states that have enacted deregulation and retail choice legislation. Some have combined retail choice with an ISO and power exchange; others have opted for retail choice without either. In the past, Interconnected Operations Services (IOS) were obtained by informal means within the same company. Generation is now being actively bought and sold as companies align their strategic direction with different sectors of the emerging electric industry. In the future, these IOS will have to be obtained by formal arrangements. The formal arrangements will need to encompass parameters including service definitions, compensation, performance measurement, and performance incentives. These formal arrangements are presently taking different forms in the industry depending on the stage of deregulation in each area, and on the particular agreements made by each Control Area. This paper describes how VIUs obtained and dispatched the IOS needed for reliability, and what challenges will be faced with respect to these services.

    2008-01-01

    Full Text Available The first part of this paper analyses the regulatory framework for international trade in financial services within the auspices of the World Trade Organization (WTO, with special attention paid to the open issues including the scope of prudential measures and capital mobility limitations. The process of the international integration of the South Eastern Europe (SEE countries is mainly dictated by their goal of EU integration. With regard to the services' sectors, a major liberalization step on the way is WTO accession. Of the countries in the region only Serbia, Bosnia and Herzegovina and Montenegro are still not WTO members and in order to become members significant liberalization commitments will be demanded of them. For this reason the second part of the paper deals with concrete financial liberalization commitments undertaken by the original WTO members in SEE and the newly WTO acceded SEE member countries. The last part of the paper provides a quantitative analysis of these commitments by means of the measurement of liberalization indices in the banking sectors in SEE countries. This is to provide a general idea of the scope of liberalization that may be required from a SEE country in order to achieve WTO membership on the road to EU integration.

  20. IRLT: Integrating Reputation and Local Trust for Trustworthy Service Recommendation in Service-Oriented Social Networks.

    Directory of Open Access Journals (Sweden)

    Zhiquan Liu

    Full Text Available With the prevalence of Social Networks (SNs and services, plenty of trust models for Trustworthy Service Recommendation (TSR in Service-oriented SNs (S-SNs have been proposed. The reputation-based schemes usually do not contain user preferences and are vulnerable to unfair rating attacks. Meanwhile, the local trust-based schemes generally have low reliability or even fail to work when the trust path is too long or does not exist. Thus it is beneficial to integrate them for TSR in S-SNs. This work improves the state-of-the-art Combining Global and Local Trust (CGLT scheme and proposes a novel Integrating Reputation and Local Trust (IRLT model which mainly includes four modules, namely Service Recommendation Interface (SRI module, Local Trust-based Trust Evaluation (LTTE module, Reputation-based Trust Evaluation (RTE module and Aggregation Trust Evaluation (ATE module. Besides, a synthetic S-SN based on the famous Advogato dataset is deployed and the well-known Discount Cumulative Gain (DCG metric is employed to measure the service recommendation performance of our IRLT model with comparing to that of the excellent CGLT model. The results illustrate that our IRLT model is slightly superior to the CGLT model in honest environment and significantly outperforms the CGLT model in terms of the robustness against unfair rating attacks.

  1. [Community integrated services for persons with mental illness].

    2007-10-01

    Anti-psychotic medications have changed the lives and treatment of persons with mental illness for the better since the social isolation of the 1950s and earlier. Community support programs break down barriers surrounding mental patients, but the stigma and negative attitudes about mental illness continue to block the development of community-based services. Individuals struggling to overcome a mental health issue find themselves facing a constant series of rejections and exclusions. Now that the Mental Health Law and Physically and Mentally Disabled Citizens Protection Act have been amended by The Legislative Yuan, the government will need to review the design of the Mental Health Care Network Project and to promote and facilitate friendly supportive communities for the mentally ill. All of us have to face these challenges to find a new balance between the civil rights of the public and the mentally ill. This paper examines issues concerning the gap between the development of the mental health system and the needs of patients and their families in the last two decades. The system often falls short of meeting needs. To meet the mental health needs of the people and make effective use of resources, changes must be made in the way services are designed, organized and delivered. The process of reforming mental health services, moreover, must not take money away from other services. Instead, changes must be made by reallocating funds. Following the revised Mental Health Law, the government should begin now to develop implementation planning guidelines to establish a comprehensive and integrated mental health services system, especially for the 80?% of patients with mild or moderate mental health problems who live in the community. We will monitor the process carefully, and ensure that patients and their families get the services they need, and help them remain in their communities as far as possible.

    ABSTRACT This paper describes the development process of the Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM – National Survey on Access, Use and Promotion of Rational Use of Medicines) based on an integrated approach to pharmaceutical services, science, technology and innovation. It starts by contextualizing health and development in Brazil and features elements of the National Policy for Science, Technology and Innovation in Health in Brazil and the National Policy for Pharmaceutical Services. On presenting pharmaceutical policy guidelines, it stresses the lack of nationwide data. This survey, commissioned by the Brazilian Ministry of Health, has two components: household survey and evaluation of pharmaceutical services in primary care. The findings point to perspectives that represent, besides the enhancement of public policy for pharmaceutical services and public health, results of government action aimed at developing the economic and industrial health care complex to improve the health conditions of the Brazilian population.

    In the wake of the 1994 International Conference on Population and Development in Cairo, considerable activity has occurred both in national policymaking for reproductive health and in research on the implementation of the Cairo Program of Action. This report considers how effectively a key component of the Cairo agenda--integration of the management of sexually transmitted infections, including human immunodeficiency virus, with maternal and child health-family planning services--has been implemented. Quantitative and qualitative data are used to illuminate the difficulties faced by implementers of reproductive health programs in Ghana, Kenya, South Africa, and Zambia. In these countries, clear evidence is found of a critical need to reexamine the continuing focus on family planning services and the nature of the processes by which managers implement reproductive health policies. Implications of findings for policy and program direction are discussed.

    The 38640 core Cray XT4"Franklin" system at the National Energy Research Scientific Computing Center (NERSC) is a massively parallel resource available to Department of Energy researchers that also provides on-demand grid computing to the Open Science Grid. The integration of grid services on Franklin presented various challenges, including fundamental differences between the interactive and compute nodes, a stripped down compute-node operating system without dynamic library support, a shared-root environment and idiosyncratic application launching. Inour work, we describe how we resolved these challenges on a running, general-purpose production system to provide on-demand compute, storage, accounting and monitoring services through generic grid interfaces that mask the underlying system-specific details for the end user.

  7. Integrated Cloud-Based Services for Medical Workflow Systems

    2016-12-01

    Full Text Available Recent years have witnessed significant progress of workflow systems in different business areas. However, in the medical domain, the workflow systems are comparatively scarcely researched. In the medical domain, the workflows are as important as in other areas. In fact, the flow of information in the healthcare industry is even more critical than it is in other industries. Workflow can provide a new way of looking at how processes and procedures are completed in particular medical systems, and it can help improve the decision-making in these systems. Despite potential capabilities of workflow systems, medical systems still often perceive critical challenges in maintaining patient medical information that results in the difficulties in accessing patient data by different systems. In this paper, a new cloud-based service-oriented architecture is proposed. This architecture will support a medical workflow system integrated with cloud services aligned with medical standards to improve the healthcare system.

    2015-12-01

    The pace and scale of environmental change is undermining the conditions for human health. Yet the environment and human health remain poorly integrated within research, policy and practice. The ecosystem services (ES) approach provides a way of promoting integration via the frameworks used to represent relationships between environment and society in simple visual forms. To assess this potential, we undertook a scoping review of ES frameworks and assessed how each represented seven key dimensions, including ecosystem and human health. Of the 84 ES frameworks identified, the majority did not include human health (62%) or include feedback mechanisms between ecosystems and human health (75%). While ecosystem drivers of human health are included in some ES frameworks, more comprehensive frameworks are required to drive forward research and policy on environmental change and human health.

    Full Text Available If businesses want to benefit from the power of the Internet, web siteshave to evolve. It is often no longer beneficial for them to only provide staticinformation. It is necessary for these web sites to find ways that allow them tointeract with other websites, operating systems, and applications. With Webservices it is finally possible to create functions that can easily be accessed over theInternet by both internal and external parties. In other words, with Web services it ispossible to integrate different value chains from different organizations with ease.On the other hand, workflows provide tools and mechanisms for managing theinteraction between people, systems, applications and business functions. Thecombination of these two technologies offers a very powerful solution forbusinesses integration.

    2012-01-01

    This is a study of organizational change strategies employed in seven county human service agencies to improve the coordination of services through the structural integration of previously free standing organizations or the development of voluntary interagency collaborative service delivery systems. The central question involves the identification of organizational change tactics which contributed to the success of the organizational change initiatives. The literature on organizational change is reviewed, with particular attention to a framework developed by Fernandez and Rainey based on their extensive review and synthesis of the research on successful change strategies in the public and business sectors. Qualitative and quantitative data were gathered from over 250 individuals and from agency documents. Findings are compared with the success factors identified by Fernandez and Rainey, and refinements to their propositions are suggested. More precise methods for measuring successful and unsuccessful change initiatives are suggested. Implications for practice and research are presented.

    2009-01-01

    The healthcare industry is facing several challenges such as the reduction of costs and quality improvement of the provided services. Engineering studies could be very useful in supporting organizational and management processes. Healthcare service efficiency depends on a strong collaboration between clinical and engineering experts, especially when it comes to analyzing the system and its constraints in detail and subsequently, when it comes to deciding on the reengineering of some key activities. The purpose of this paper is to propose a case study showing how a mix of representation tools allow a manager of a radiology department to solve some human and technological resource re-organizational issues, which have to be faced due to the introduction of a new technology and a new portfolio of services. In order to simulate the activities within the radiology department and examine the relationship between human and technological resources, different visual diagrammatic language (VDL) techniques have been implemented to get knowledge about the heterogeneous factors related to the healthcare service delivery. In particular, flow charts, IDEFO diagrams and Petri nets have been integrated each other with success as a modelisation tools. The simulation study performed through the application of the aforementioned VDL techniques suggests the opportunity of re-organizing the nurse activities within the radiology department. The re-organization of a healthcare service and in particular of a radiology department by means of joint flow charts, IDEF0 diagrams and Petri nets is a poorly investigated topic in literature. This paper demonstrates how flow charts and IDEF0 can help people working within the department to understand the weak points of their organization and constitute an efficient base of knowledge for the implementation of a Petri net aimed at improving the departmental performance.

    2007-12-01

    Full Text Available Abstract Background Comparative data are an important resource for management of integrated care. In 2001, the English Department of Health created 34 cancer networks, broadly serving populations of half to three million people, to coordinate cancer services across providers. We have investigated how national and regional routine data are used by the cancer network management teams. Methods Telephone interviews using a standardised semi-structured questionnaire were conducted with 68 participants in 29 cancer network teams. Replies were analysed both quantitatively and qualitatively. Results While most network teams had a formal information strategy, data were used ad hoc more than regularly, and were not thought to be as influential in network decision making as other sources of information. Data collection was more prominent in information strategies than data use. Perceptions of data usefulness were mixed and there were worries over data quality, relevance, and potential misuse. Participants were receptive to the idea of a new limited dataset collating comparative data from currently available routine data sources. Few network structural factors were associated with data use, perceptions of current data, or receptivity to a new dataset. Conclusion Comparative data are underused for managing integrated cancer services in England. Managers would welcome more comparative data, but also desired data to be relevant, quality assured and contextualised, and for the teams to be better resourced for data use.

  14. Paper on Proposed System for Placing Free Call over Wi-Fi Network Using Voip and SIP

    Full Text Available The Wi-Fi, also known as 802.11b, has become the preferred technology for wireless local area networking in both business and home environments. Even though it was designed primarily for private applications, Wi-Fi is also being deployed in public places to create so-called hotspots, where Wi-Fi-capable users can obtain internet access. This new domain of application could be the major future market opportunity for Wi-Fi, but in order to take advantage of it, several key challenges, both technical and business-related, must be overcome. Today the most cost effective use of Wi-Fi is calling over network. We have various facilities today such as Skype, T-Mobile, T-pad, Jaxtr for communicating over network but some restriction are placed on such system like Skype support only pc to pc calling for cellular and landline call this free service become paid. T mobile also follows the same problem. Hence to overcome such issue we are developing a system which allows free calling over Wi-Fi network using VoIP service. Our system allows peer to peer calling and an additional feature of group calling. For supporting group calling feature we are using SIP (Session Initiation Protocol. This technology will help us to find a way for free calling and thus ultimately helps to private organization for reducing bills over communication. In this paper, the system will be implemented as well as the performance will be tested by doing actual implementation of this system.

    移动微波存取全球互通(WiMAX)网络使用了5种调度机制来保证服务质量,其中的3种被设计用于实时性业务.但是,这3种调度机制都缺乏公平性.在资源不足的时候,通过丢弃新用户的请求来保证旧用户的服务质量(QoS).为此,针对WiMAX中的因特网语音(VoIP)服务提出了一种基于优先权的新调度机制.该机制中,不同用户的业务请求将被赋予不同的优先权.新旧用户同时请求资源时,新用户的请求拥有更高的优先权;资源分配中心再根据优先权的高低为用户分配资源,从而在最大限度上保证了资源分配的公平性.仿真结果显示,新调度机制可以将网络中的因特网语音服务的连接数和总吞吐量分别提高15%和11%左右.%Five scheduling mechanisms have been proposed to ensure Quality of Service (QoS) in WiMAX network.Three of them are designed for real-time applications. However, fairness has not been considered while assigning resources in these scheduling mechanisms. In order to guarantee the existing services, new service requests will be rejected when lacking network resources. For resolving this problem, a new scheduling mechanism was proposed for Voice over Internet Protocol (VoIP) service, in which a Priority Decision Maker (PDM) was implanted. When new services and the existing services requested resources simultaneously, higher priority would be assigned to new service requests; and resource allocation would be achieved based on different level priorities by a resource distribution center for guaranteeing fairness. Detailed performance analysis was performed. The simulation results show the proposed scheduling mechanism could significantly increase number of VoIP connections and total throughput, about 15% and 11% respectively.

    Full Text Available Participation in mental health care poses many challenges for mental health service users and service providers. Consideration of these issues for improving the integration of service user participation in mental health care can help to inform integrated care within health care systems, broadly. This paper argues for practicing greater empathy and teaching it, stigma reduction, changing what we measure, valuing the intrinsic aspects of care more, employing more people with lived experience within mental health services, raising the visibility of service users as leaders and our teachers within services and redefining integrated care from the service user perspective.

  17. REST-MapReduce: An Integrated Interface but Differentiated Service

    2014-01-01

    Full Text Available With the fast deployment of cloud computing, MapReduce architectures are becoming the major technologies for mobile cloud computing. The concept of MapReduce was first introduced as a novel programming model and implementation for a large set of computing devices. In this research, we propose a novel concept of REST-MapReduce, enabling users to use only the REST interface without using the MapReduce architecture. This approach provides a higher level of abstraction by integration of the two types of access interface, REST API and MapReduce. The motivation of this research stems from the slower response time for accessing simple RDBMS on Hadoop than direct access to RDMBS. This is because there is overhead to job scheduling, initiating, starting, tracking, and management during MapReduce-based parallel execution. Therefore, we provide a good performance for REST Open API service and for MapReduce, respectively. This is very useful for constructing REST Open API services on Hadoop hosting services, for example, Amazon AWS (Macdonald, 2005 or IBM Smart Cloud. For evaluating performance of our REST-MapReduce framework, we conducted experiments with Jersey REST web server and Hadoop. Experimental result shows that our approach outperforms conventional approaches.

    1994-08-01

    The demand for integrated services local area networks is increasing at a rapid pace with the advent of many new and exciting applications: office and factory automation, distributed computing, and multimedia communications. To support these new applications, it is imperative to integrate traffic with diverse statistical characteristics and differing delay requirements on the same network. An attractive approach for integrating traffic has been adopted in two token passing local area network standards, the IEEE 802.4 token bus standard and FDDI. The idea is to control the transmissions of each station based on a distributed timing algorithm, so as to achieve the following goals: (1) to limit the token cycles so that time-critical traffic can be accommodated, and (2) to allocate pre-specified bandwidths to different stations when the network is overloaded. We have investigated the analysis and design of this protocol. In this paper, we generalize the transmission control algorithm used previously. The major advantages of the generalization over the original protocol are: (1) it provides a much expanded design space, (2) it guarantees convergent behavior, and (3) it gives meaningful insights into the dynamics of the basic control algorithm.

    The number of people over 65 years old throughout most stable and prosperous countries in the world is increasing. Availability of their care in their own homes is imperative because of the economic reasons and their choices where to live (World Health Organization, Definition of an older or elderly person. http://www.who.int/healthinfo/survey/ageingdefnolder/en/ ; EQUIP-European Framework for Qualifications in Home Care Services for Older People, http://www.equip-project.com ; Salonen, 2009). "Recent advancement in wireless communications and electronics has enabled the development of low-cost sensor networks. The sensor networks can be utilized in various application areas." (Akyildiz, et al. 2002) These two statements show that there is a great promise in wireless technology and utilizing it in assisted living might be very beneficial to the elderly people. In this paper, we propose software architecture called Location Windows Service (LWS) which integrates the Radio Frequency Identification (RFID) technology and the web service to build an assisted living system for elderly people at home. This architecture monitors the location of elderly people without interfering in their daily activities. Location information messages that are generated as the elderly move from room to room indicate that the elderly person is fit and healthy and going about their normal life. The communication must be timely enough to follow elderly people as they move from room to room without missing a location. Unacknowledged publishing, subscription filtering and short location change messages are also included in this software model to reduce the network traffic in large homes. We propose some defense schemes being applied to the network environment of the assisted living system to prevent any external attacks.

    Full Text Available This paper reports on the design and implementation of a multi-phase interactive process among a set of scientists, policy makers, land managers, and community representatives, so as to facilitate communication, mutual understanding, and participative decision making. This was part of the Ecosystem Services Project in Australia. The project sought to broaden public understanding about the natural ecosystems in Australia. The study reported here pertains to one of the project sites--the Goulburn Broken catchment, a highly productive agricultural watershed in the south-east of Australia. The paper demonstrates how, starting from a condition of diversity of ideas and interests among the participants, systematic dialogue and mutual learning could be generated, leading to identification of options for more sustainable land management practices. The concept of “ecosystem services” was used as an integrative tool across disciplines and community perspectives. The concept of scenarios was used to encourage future-focussed thinking among the participants. The idea of “stakeholder jury” was used to promote deliberation. A process of multi-criteria evaluation was used to facilitate convergence of viewpoints, through informed trade-offs and compromises. This experience led to the development of a process for integration research, which helped in harmonising across diverse understandings and values in a transparent and structured manner.

  11. A Scalable Architecture for VoIP Conferencing

    2003-10-01

    Full Text Available Real-Time services are traditionally supported on circuit switched network. However, there is a need to port these services on packet switched network. Architecture for audio conferencing application over the Internet in the light of ITU-T H.323 recommendations is considered. In a conference, considering packets only from a set of selected clients can reduce speech quality degradation because mixing packets from all clients can lead to lack of speech clarity. A distributed algorithm and architecture for selecting clients for mixing is suggested here based on a new quantifier of the voice activity called "Loudness Number" (LN. The proposed system distributes the computation load and reduces the load on client terminals. The highlights of this architecture are scalability, bandwidth saving and speech quality enhancement. Client selection for playing out tries to mimic a physical conference where the most vocal participants attract more attention. The contributions of the paper are expected to aid H.323 recommendations implementations for Multipoint Processors (MP. A working prototype based on the proposed architecture is already functional.

    Full Text Available Performing Bioinformatic´s experiments involve an intensive access to distributed services and information resources through Internet. Although existing tools facilitate the implementation of workflow-oriented applications, they lack of capabilities to integrate services beyond low-scale applications, particularly integrating services with heterogeneous interaction patterns and in a larger scale. This is particularly required to enable a large-scale distributed processing of biological data generated by massive sequencing technologies. On the other hand, such integration mechanisms are provided by middleware products like Enterprise Service Buses (ESB, which enable to integrate distributed systems following a Service Oriented Architecture. This paper proposes an integration platform, based on enterprise middleware, to integrate Bioinformatics services. It presents a multi-level reference architecture and focuses on ESB-based mechanisms to provide asynchronous communications, event-based interactions and data transformation capabilities. The paper presents a formal specification of the platform using the Event-B model.

  18. User-Perceived Quality Assessment for VoIP Applications

    CERN Document Server

    Beuran, R; CERN. Geneva

    2004-01-01

    We designed and implemented a system that permits the measurement of network Quality of Service (QoS) parameters. This system allows us to objectively evaluate the requirements of network applications for delivering user-acceptable quality. To do this we compute accurately the network QoS parameters: one-way delay, jitter, packet loss and throughput. The measurement system makes use of a global clock to synchronise the time measurements in different points of the network. To study the behaviour of real network applications specific metrics must be defined in order to assess the user-perceived quality (UPQ) for each application. Since we measure simultaneously network QoS and application UPQ, we are able to correlate them. Determining application requirements has two main uses: (i) to predict the expected UPQ for an application running over a given network (based on the corresponding measured QoS parameters) and understand the causes of application failure; (ii) to design/configure networks that provide the ne...

    Planetary exploration missions produce a wealth of geospatial data, largely from imaging experiments. Data discovery and access can rely on Terrestrial geospatial standards [1], or Virtual Observatory (VO) approach of EuroPlanet-RI H2020 VESPA [2]. Integrating the two is the aim of VESPA Surface Task. VO-GIS interoperability facilitates discovery, display, access and use of geospatial data. In combination with non-surface imaging datasets, it has a potential for interdisciplinary science. We provide geospatial data through VO (Virtual Observatory) TAP (Table Access Protocol) on a dedicated server. Our service runs GAVO DaCHS (Data Center Helper Suite) and is registered with the IVOA (International Virtual Observatory Alliance). Currently exposed tables are: (a) usgs_wms - VO/GIS access to USGS-served WMS (Web Map Service) [3]; (b) crism - CRISM data on [4], with a JavaScript viewer where a spectrum selected on a preview can be visualized in a browser or broadcasted to VO tools; (c) mars_craters - Mars Crater Catalog [5]. Footprint polygons in crism and mars_craters can be sent to the VO viewing tool Aladin. Support from the latter for complex polygons will allow for improved, GIS-like search and data access capabilities. The exposure of additional planetary OGC services is planned. Current work involves the development of a Desktop GIS (QGIS) plugin to enable VO-access and expanding the range of datasets suitable for surface mapping and analysis. All of our developments are Open Source and our code and tools are available on the VESPA GitHub organization page and repositories therein [6]. References[1] Hare et al. (2015) LPSC XLVI, #2476.

    2007-01-01

    This article describes a study by co-integration test and Granger causality test on the relationships between China's services trades and employment using the data of services trade from the WTO website and the employment data from China Statistic Yearbook for the years from 1982 to 2003. Co-integration test showed that 1% increase in export value and import value of services created respectively 0.205% and 0.068 7% more job opportunities in the service sector. Both export and import of services impacted positively on employment in service industry, and export did more than import. However, in the short run, the impacts of services export and import on employment in service industry were both very small, though positive; and the impacts of employment in service industry on both export and import of services were very big, but not stable. Granger causality test indicated that employment in service industry was a Granger cause of services export. The findings highlight the importance of facilitating services import and reducing import barriers, and suggest that the competitiveness of China's labor-intensive services trade can be exploited to boost services export and help employment in service sector, and that the structure of services trade should be optimized by shifting from labor-intensive to knowledge-and technology-intensive services thus to enhance China's competitiveness of services export.

    Full Text Available Jaringan intranet Universitas Udayana telah menghubungkan ketiga lokasi kampus, yaitu Kampus Bukit, Kampus Sudirman, dan Kampus Nias.  Lokasi kampus yang terpisah-pisah dan kampus Bukit yang memiliki area yang cukup luas memerlukan prasarana teleponi yang memadai.  Selama ini, komunikasi teleponi masih memanfaatkan provider seperti PT Telkom, walaupun komunikasi telepon hanya untuk komunikasi antar fakultas atau antar fakultas dengan rektorat di area kampus bukit.  Demikian juga untuk komunikasi telepon antar lokasi kampus yang berbeda. Walaupun beberapa fakultas dan juga gedung Rektorat memiliki perangkat PABX namun keberadaan kebanyakan hanya melayani komunikasi dalam satu gedung saja.  Pemanfaatan intranet kampus UNUD baru dimanfaatkan untuk akses Internet, akses Sistem Informasi dan untuk videoconference. Dengan beban trafik yang ada, jaringan intranet masih memungkinkan untuk dibebani dengan trafik yang lebih tinggi. Dengan demikian, untuk mengoptimalkan pemanfaatan bandwith,  diupayakan dengan mengembangakan sistem teleponi berbasis VoIP yang memanfaatkan infrastruktur yang ada. Tujuan yang ingin dicapai adalah menyediakan fasilitas telepon internal kampus yang tidak berbayar. Melalui teknologi VoIP ini,  komunikasi dapat dilakukan dengan beberapa cara baik menggunakan telepon analog maupun softphone yang dapat diinstall di masing-masing PC atau laptop. Hal ini nanti tentu akan memberikan efisiensi waktu bagi civitas karena mudah dihubungi dan secara langsung akan berdampak pada efisiensi biaya telekomunikasi di kampus. Infrastruktur yang dikembangkan menggunakan protokol SIP memanfaatkan Free Software Linux Fedora sebagai Operating System, Asterisk dan Ondo sebagai aplikasi server.  Di sisi pemakai, perangkat telepon dapat menggunakan dua model, pertama menggunakan softphone  yang ditujukan untuk personal dengan memanfaatkan nomor induk pegawai (NIP atau nomor induk mahasiswa (NIM sebagai nomor telepon. Model telepon ini aksesnya

    Non-communicable diseases (NCD) are a growing cause of morbidity in low-income countries including in people living with human immunodeficiency virus (HIV). Integration of NCD and HIV services can build upon experience with chronic care models from HIV programmes. We describe models of NCD and HIV integration, challenges and lessons learned. A literature review of published articles on integrated NCD and HIV programs in low-income countries and key informant interviews were conducted with leaders of identified integrated NCD and HIV programs. Information was synthesised to identify models of NCD and HIV service delivery integration. Three models of integration were identified as follows: NCD services integrated into centres originally providing HIV care; HIV care integrated into primary health care (PHC) already offering NCD services; and simultaneous introduction of integrated HIV and NCD services. Major challenges identified included NCD supply chain, human resources, referral systems, patient education, stigma, patient records and monitoring and evaluation. The range of HIV and NCD services varied widely within and across models. Regardless of model of integration, leveraging experience from HIV care models and adapting existing systems and tools is a feasible method to provide efficient care and treatment for the growing numbers of patients with NCDs. Operational research should be conducted to further study how successful models of HIV and NCD integration can be expanded in scope and scaled-up by managers and policymakers seeking to address all the chronic care needs of their patients. © 2017 John Wiley & Sons Ltd.

    An increasing number of manufacturers is responsible for the complete lifecycle of their products and they must create efficient and effective circular flow economic systems. The quality of these material and product cycles depend on the logistical processes and the development of logistic concepts, which have to suffer economic and ecological aims. The complexity of the different circular economic systems need the co-operation of the different participants in order to integrate the different core abilities. The aim of this contribution is to describe the possibilities of the service providers in combining services and transports of supply and waste disposal. As well as to represent their advantages, disadvantages and possible barriers. It was possible to refer to conclusions of the research project "Konfiguration von kooperativen Kreislaufwirtschaftssystemen unter besonderer Ber'cksichtigung von Logistikdienstleistern" within the scope of the Research Center of Logistics at the University of Bremen (FoLo). The research work was carried out in a closed collaboration of the following institutes and enterprises: University of Bremen, the Institute of Shipping Economics and Logistics (ISL) and the BLG International Logistics GmbH & Co.

  12. Frequency-Domain Adaptive Algorithm for Network Echo Cancellation in VoIP

    Directory of Open Access Journals (Sweden)

    Patrick A. Naylor

    2008-05-01

    Full Text Available We propose a new low complexity, low delay, and fast converging frequency-domain adaptive algorithm for network echo cancellation in VoIP exploiting MMax and sparse partial (SP tap-selection criteria in the frequency domain. We incorporate these tap-selection techniques into the multidelay filtering (MDF algorithm in order to mitigate the delay inherent in frequency-domain algorithms. We illustrate two such approaches and discuss their tradeoff between convergence performance and computational complexity. Simulation results show an improvement in convergence rate for the proposed algorithm over MDF and significantly reduced complexity. The proposed algorithm achieves a convergence performance close to that of the recently proposed, but substantially more complex improved proportionate MDF (IPMDF algorithm.

    The geographic information service is enabled by the advancements in general Web service technology and the focused efforts of the OGC in defining XML-based Web GIS service. Based on these models, this paper addresses the issue of services chaining,the process of combining or pipelining results from several interoperable GIS Web Services to create a customized solution. This paper presents a mediated chaining architecture in which a specific service takes responsibility for performing the process that describes a service chain. We designed the Spatial Information Process Language (SIPL) for dynamic modeling and describing the service chain, also a prototype of the Spatial Information Process Execution Engine (SIPEE) is implemented for executing processes written in SIPL. Discussion of measures to improve the functionality and performance of such system will be included.

    Solar energy collected using photovoltaic (PV) technology is a clean and renewable energy source that offers multiple benefits to the electric utility industry and its customers, such as cost predictability, reduced emissions, and loss reduction by distributed installations. Renewable energy goals established in North Carolina Senate Bill 3 (SB3), in combination with the state tax credit and decreases in the cost of energy from PV panels, have resulted in rapid solar power penetration within the Carolinas services areas of Duke Energy. Continued decreases in PV prices are expected to lead to greater PV penetration rates than currently required in SB3. Despite the potential benefits, significant penetration of PV energy is of concern to the utility industry because of its impact on operating reliability and integration cost to customers, and equally important, how any additional costs may be allocated to different customer groups. Some of these impacts might become limiting factors for PV energy, especially growing distributed generation installed at customer sites. Recognizing the importance of renewable energy developments for a sustainable energy future and economic growth, Duke Energy has commissioned this study to simulate the effects of high-PV penetration rates and to initiate the process of quantifying the impacts. The objective of the study is to inform resource plans, guide operation improvements, and drive infrastructure investments for a steady and smooth transition to a new energy mix that provides optimal values to customers. The study team consists of experts from Pacific Northwest National Laboratory (PNNL), Power Costs, Inc. (PCI), Clean Power Research (CPR), Alstom Grid, and Duke Energy. PNNL, PCI, and CPR performed the study on generation impacts; Duke Energy modeled the transmission cases; and distribution simulations were conducted by Alstom Grid. PNNL analyzed the results from each work stream and produced the report.

  20. Integrated services plus drug treatment as a system alternative to crime control and parole.

    Science.gov (United States)

    Danzer, Graham

    2012-01-01

    Integrated services have the potential to facilitate recovery in drug offenders as well as reduce criminal recidivism. This is significant given that prison overcrowding has led many drug offenders to be released from custody into society via the "reentry movement." Offenders incarcerated for many years often return to society with medical, mental health, behavioral, and drug abuse issues. These issues have been found in similar populations, including those with severe mental illness and the homeless, for which integrated services has shown to have a significant impact on improving functioning. Thus the argument of this article is that because integrated services have shown to be effective with somewhat similar populations, integrated services can be effective in treating paroled drug offenders. These benefits are expected to be to a greater degree than that achieved by current system policy regarding paroled drug offenders being supervised by parole officers rather than case managers facilitating integrated services.

    IEEE 802.11e provides the mechanism to distinguish the priority for different service flows,compared to other services it improves the priority of real-time services such as VoW(Voice over Internet Protocol) in WLAN(Wireless Local Area Network),so that its QoS requirement will be satisfied to some extents,because of not providing the different priority betwcen Move Host(MH) and Access Point(AP) in WLAN,the unbalance between uplink and downlink service flow on AP is induced,and then it leads to bottleneck, further more restricts the VoIP capacity. To solve this problem,a new strategy based on the analysis of the capacity of VoIP in WLAN is proposed to improve the switch in capacity of AP's channel. It usees the length of AP's queue to estimate whether the network is congested or not,and then modifies the Arbitration Inter-Frame Space(AIFS) of the service flows dynamically,modulates the priority of AP dynamically according to web congestion condition,to weaken the restriction of VoIP capacity caused by bottleneck of AP. The results of simulation show that the proposed scheme can increase VoIP capacity efficiently.%IEEE 802.11e提供了对不同的业务流进行优先级区分的机制,提高了无线局域网(WLAN)内VoIP等实时业务相对于其他业务流的优先性,从而在一定程度上保障其QoS要求,但并没有对WLAN中移动节点(MH)和接入节点(AP)进行优先级的区分,导致AP处上下行业务流量的不平衡,并造成瓶颈效应,限制了VoIP容量.针对这一问题,在对WLAN中VoIP进行容量分析的基础上,提出一种改进AP信道接入能力的策略.通过对AP中队列长度的检测来判断网络拥塞程度,从而动态调整AP的仲裁帧间间隔(AIFS),以达到根据网络拥塞状况来动态调整AP的优先级,弱化AP的瓶颈效应对VoIP容量制约的目的.仿真结果表明,所提出的改进方案能够有效地提高WLAN中的VoIP容量.

    Okabe, Tatsuya; Matsumoto, Keinosuke; Mori, Naoki

    While abundant information can be referred to the Internet Cloud, it is becoming difficult for a user to acquire desired information pertinently. Therefore, it is necessary to support an unfamiliar user to IT to offer the information suitable for user's preference. This research proposes a service integration supporting system equipped with recommendation function based on a user's preference. The research regards bookmarks on Web browser and tags given to Web services as information showing a user's preference, and a user profile is created using them. A service integration model is built and the proposed system recommends some appropriate example of integrated services. As compared with conventional supporting systems, the proposed system requires less amount of work for creation or execution of service integration.

    Full Text Available The surge of donor funds to fight HIV&AIDS epidemic inadvertently resulted in the setup of laboratories as parallel structures to rapidly respond to the identified need. However these parallel structures are a threat to the existing fragile laboratory systems. Laboratory service integration is critical to remedy this situation. This paper describes an approach to quantitatively measure and track integration of HIV-related laboratory services into the mainstream laboratory services and highlight some key intervention steps taken, to enhance service integration.A quantitative before-and-after study conducted in 122 Family Health International (FHI360 supported health facilities across Nigeria. A minimum service package was identified including management structure; trainings; equipment utilization and maintenance; information, commodity and quality management for laboratory integration. A check list was used to assess facilities at baseline and 3 months follow-up. Level of integration was assessed on an ordinal scale (0 = no integration, 1 = partial integration, 2 = full integration for each service package. A composite score grading expressed as a percentage of total obtainable score of 14 was defined and used to classify facilities (≤ 80% FULL, 25% to 79% PARTIAL and <25% NO integration. Weaknesses were noted and addressed.We analyzed 9 (7.4% primary, 104 (85.2% secondary and 9 (7.4% tertiary level facilities. There were statistically significant differences in integration levels between baseline and 3 months follow-up period (p<0.01.

    The surge of donor funds to fight HIV&AIDS epidemic inadvertently resulted in the setup of laboratories as parallel structures to rapidly respond to the identified need. However these parallel structures are a threat to the existing fragile laboratory systems. Laboratory service integration is critical to remedy this situation. This paper describes an approach to quantitatively measure and track integration of HIV-related laboratory services into the mainstream laboratory services and highlight some key intervention steps taken, to enhance service integration. A quantitative before-and-after study conducted in 122 Family Health International (FHI360) supported health facilities across Nigeria. A minimum service package was identified including management structure; trainings; equipment utilization and maintenance; information, commodity and quality management for laboratory integration. A check list was used to assess facilities at baseline and 3 months follow-up. Level of integration was assessed on an ordinal scale (0 = no integration, 1 = partial integration, 2 = full integration) for each service package. A composite score grading expressed as a percentage of total obtainable score of 14 was defined and used to classify facilities (≤ 80% FULL, 25% to 79% PARTIAL and <25% NO integration). Weaknesses were noted and addressed. We analyzed 9 (7.4%) primary, 104 (85.2%) secondary and 9 (7.4%) tertiary level facilities. There were statistically significant differences in integration levels between baseline and 3 months follow-up period (p<0.01). Baseline median total integration score was 4 (IQR 3 to 5) compared to 7 (IQR 4 to 9) at 3 months follow-up (p = 0.000). Partial and fully integrated laboratory systems were 64 (52.5%) and 0 (0.0%) at baseline, compared to 100 (82.0%) and 3 (2.4%) respectively at 3 months follow-up (p = 0.000). This project showcases our novel approach to measure the status of each laboratory on the integration continuum.

    Full Text Available Research on service-learning has focused mainly on student outcomes. However, this study addresses the transformative change that three faculty members from different disciplines experienced during a semester-long fellowship on servicelearning as a pedagogical method. Through their personal reflections, the authors show how service-learning and the scholarship of teaching were intertwined as they engaged in course redesign. This experience went beyond creating an academic service-learning course to transforming the teachers into reflective practitioners actively engaged in systematically improving their teaching practice.

    It is considered that ATM is not suitable for traditional narrowband services such as voice because of large adapting delay. In this paper,we present an ATM-based broadband switching system, which is capable of supporting narrowband services. A composite cell adapting method is adopted in this system to reduce adapting delay and guarantee QoS (Quality of Service). In the realized system, several key parameters have been measured. The results prove that it can guarantee perfect QoS and relative high bandwidth efficiency.

    Sun, Zhaohao; Sun, Junqing; Meredith, Grant

    Customer decision making (CDM) is an indispensable factor for web services. This article examines CDM in web services with a novel P6 model, which consists of the 6 Ps: privacy, perception, propensity, preference, personalization and promised experience. This model integrates the existing 6 P elements of marketing mix as the system environment of CDM in web services. The new integrated P6 model deals with the inner world of the customer and incorporates what the customer think during the DM process. The proposed approach will facilitate the research and development of web services and decision support systems.

    NASA Goddard has been investing in technology demonstrations of a beacon service, now called Next Generation Broadcast Services (NGBS). NGBS is a global, space-based, communications and navigation service for users of Global Navigation Satellite Systems (GNSS) and the Tracking and Data Relay Satellite System (TDRSS). NGBS will provide an S-band beacon messaging source and radio navigation available to users at orbital altitudes 1400 km and below, increasing the autonomy and resiliency of onboard communication and navigation. NGBS will deliver both one-way radiometric (Doppler and pseudorange) and fast forward data transport services to users. Portions of the overall forward data volume will be allocated for fixed message types while the remaining data volume will be left for user forward command data. The NGBS signal will reside within the 2106.43 MHz spectrum currently allocated for the Space Networks multiple access forward (MAF) service and a live service demonstration is currently being planned via the 2nd and 3rd generation TDRS satellites.

    Given the imperative to scale up integrated tuberculosis (TB) and HIV services in settings where both are of major public health importance, we aimed to synthesise knowledge concerning implementation of TB/HIV service integration. Systematic review of studies describing a strategy to facilitate TB and HIV service integration, searching 15 bibliographic databases including Medline, Embase and the Cochrane library; and relevant conference abstracts. Sixty-three of 1936 peer-reviewed articles and 70 of 170 abstracts met our inclusion criteria. We identified five models: entry via TB service, with referral for HIV testing and care; entry via TB service, on-site HIV testing, and referral for HIV care; entry via HIV service with referral for TB screening and treatment; entry via HIV service, on-site TB screening, and referral for TB diagnosis and treatment; and TB and HIV services provided at a single facility. Referral-based models are most easily implemented, but referral failure is a key risk. Closer integration requires more staff training and additional infrastructure (e.g. private space for HIV counselling; integrated records). Infection control is a major concern. More integrated models hold potential efficiencies from both provider and user perspective. Most papers report 'outcomes' (e.g. proportion of TB patients tested for HIV); few report downstream 'impacts' such as outcomes of TB treatment or antiretroviral therapy. Very few studies address the perspectives of service users or staff, or costs or cost-effectiveness. While scaling up integrated services, robust comparisons of the impacts of different models are needed using standardised outcome measures. © 2012 Blackwell Publishing Ltd.

    To examine various models of integrated and/or one stop shop (OSS) sexual health services (including general practice, mainstream specialist services, and designated young people's services) and explore their relative strengths and weaknesses. Literature review and interviews with key informants involved in developing the National Strategy for Sexual Health and HIV (n = 11). The paper focuses on five broad perspectives (logistics, public health, users, staff, and cost). Contraceptive and genitourinary medicine issues are closely related. However, there is no agreement about what is meant by having "integrated" services, about which services should be integrated, or where integration should happen. There are concerns that OSSs will result in over-centralisation, to the disadvantage of stand alone and satellite services. OSS models are potentially more user focused, but the stigma that surrounds sexual health services may create an access barrier. From staff perspectives, the advantages are greater career opportunities and increased responsibility, while the disadvantages are concern that OSSs will result in loss of expertise and professional status. Cost effectiveness data are contradictory. Although there is a policy commitment to look at how integrated services can be better developed, more evidence is required on the impact and appropriateness of this approach.

    Cashman, Suzanne B; Seifer, Sarena D

    2008-09-01

    In 2003, the Institute of Medicine (IOM) described public health as "an essential part of the training of citizens," a body of knowledge needed to achieve a public health literate citizenry. To achieve that end, the IOM recommended that "all undergraduates should have access to education in public health." Service-learning, a type of experiential learning, is an effective and appropriate vehicle for teaching public health and developing public health literacy. While relatively new to public health, service-learning has its historical roots in undergraduate education and has been shown to enhance students' understanding of course relevance, change student and faculty attitudes, encourage support for community initiatives, and increase student and faculty volunteerism. Grounded in collaborative relationships, service-learning grows from authentic partnerships between communities and educational institutions. Through emphasizing reciprocal learning and reflective practice, service-learning helps students develop skills needed to be effective in working with communities and ultimately achieve social change. With public health's enduring focus on social justice, introducing undergraduate students to public health through the vehicle of service-learning as part of introductory public health core courses or public health electives will help ensure that our young people are able to contribute to developing healthy communities, thus achieving the IOM's vision.

    2012-05-01

    This article presents a hybrid wireless network integration scheme in cloud services-based enterprise information systems (EISs). With the emerging hybrid wireless networks and cloud computing technologies, it is necessary to develop a scheme that can seamlessly integrate these new technologies into existing EISs. By combining the hybrid wireless networks and computing in EIS, a new framework is proposed, which includes frontend layer, middle layer and backend layers connected to IP EISs. Based on a collaborative architecture, cloud services management framework and process diagram are presented. As a key feature, the proposed approach integrates access control functionalities within the hybrid framework that provide users with filtered views on available cloud services based on cloud service access requirements and user security credentials. In future work, we will implement the proposed framework over SwanMesh platform by integrating the UPnP standard into an enterprise information system.

    In environments like factories, buildings, and homes automation services tend to often change during their lifetime. Changes are concerned to business rules, process optimization, cost reduction, and so on. It is important to provide a smooth and straightforward way to deal with these changes so that could be handled in a faster and low cost manner. Some prominent solutions use the flexibility of Wireless Sensor Networks and the meaningful description of Semantic Web Services to provide service integration. In this work, we give an overview of current solutions for machinery integration that combine both technologies as well as a discussion about some perspectives and open issues when applying Wireless Sensor Networks and Semantic Web Services for automation services integration.

    Nowadays, the IP Multimedia Subsystem (IMS) is a promising research field. Many ongoing works related to the security and the performances of its employment are presented to the research community. Although, the security and data privacy aspects are very important in the IMS global objectives, they observe little attention so far. Secure access to multimedia services is based on SIP and HTTP digest on top of IMS architecture. The standard deploys AKA-MD5 for the terminal authentication. The third Generation Partnership Project (3GPP) provided Generic Bootstrapping Architecture (GBA) to authenticate the subscriber before accessing multimedia services over HTTP. In this paper, we propose a new IMS Service Authentication scheme using Identity Based cryptography (IBC). This new scheme will lead to better performances when there are simultaneous authentication requests using Identity-based Batch Verification. We analyzed the security of our new protocol and we presented a performance evaluation of its cryptographi...

    This paper proposes a cross-layer dual adaptive coded modulation architecture using turbo codes for mobile multimedia communication, which adapts to both the varying channel characteristics and the QoS of various multimedia services simultaneously to increase the average system throughput substantially. A pragmatic channeladaptive turbo coded modulation scheme, which comes within 2.5 Db of the Shannon limit, is optimally designed,and then a QoS-adaptive scheme is superimposed to build the dual adaptive architecture. Simulation results show that the novel dual adaption reduces the gap from the fading channel capacity to 2 Db when assuming different services occur in equal probability and the service duration follows exponential distribution.

    Patients affected by progressive long-term neurological conditions might benefit from specialist palliative care involvement. However, little is known on how neurology and specialist palliative care services interact. This study aimed to map the current level of connections and integration between these services. The mapping exercise was conducted in eight centres with neurology and palliative care services in the United Kingdom. The data were provided by the respective neurology and specialist palliative care teams. Questions focused on: i) catchment and population served; ii) service provision and staffing; iii) integration and relationships. Centres varied in size of catchment areas (39-5,840 square miles) and population served (142,000-3,500,000). Neurology and specialist palliative care were often not co-terminus. Service provisions for neurology and specialist palliative care were also varied. For example, neurology services varied in the number and type of provided clinics and palliative care services in the settings they work in. Integration was most developed in Motor Neuron Disease (MND), e.g., joint meetings were often held, followed by Parkinsonism (made up of Parkinson's Disease (PD), Multiple-System Atrophy (MSA) and Progressive Supranuclear Palsy (PSP), with integration being more developed for MSA and PSP) and least in Multiple Sclerosis (MS), e.g., most sites had no formal links. The number of neurology patients per annum receiving specialist palliative care reflected these differences in integration (range: 9-88 MND, 3-25 Parkinsonism, and 0-5 MS). This mapping exercise showed heterogeneity in service provision and integration between neurology and specialist palliative care services, which varied not only between sites but also between diseases. This highlights the need and opportunities for improved models of integration, which should be rigorously tested for effectiveness.

    2016-04-01

    Universal health coverage (UHC) is at the heart of the new 2030 Agenda for Sustainable Development. Health service integration is seen by World Health Organization as an essential requirement to achieve UHC. However, to date the debate on service integration has focused on perceived benefits rather than empirical impact. We conducted a global review in a systematic manner searching for empirical outcomes of service integration experiments in UHC countries and those on the path to UHC. Sixty-seven articles and reports were found. We grouped results into a unique integration typology with six categories - medical staff from different disciplines; patients and medical staff; care package for one medical condition; care package for two or more medical conditions; specialist stand-alone services with GP services; community locations. We showed that it is possible to integrate services in different human development contexts delivering positive outcomes for patients and clinicians without incurring additional costs. However, the improved outcomes shown were incremental rather than radical and suggest that integration is likely to enhance already well established systems rather than fundamentally changing the outcomes of care.

    2016-05-01

    The prevalence of violence against women worldwide raises the question of the desirability and feasibility of integrating interpersonal violence (IPV) services within abortion care. By examining present services and context in an Inner London borough in the UK, this situation analysis explored the hypothesis that an established, integrated, health-based service (comprising raised awareness, staff training in routine IPV enquiry and referral to a community-based in-reach IPV service) would be transferable into abortion services. Four sources of qualitative data investigated views on integrating services: key stakeholder in-depth interviews including with providers of abortion and IPV services and commissioners and IPV survivors with past abortion service use (3 user, 15 provider); qualitative analysis of the open-ended part of a survey of current abortion service users with and without experience of IPV; feedback from an interactive workshop and data from field observations. While there was consensus among all informants that women experiencing IPV and seeking abortion have unidentified, unaddressed needs, how any intervention might be organised to address these needs was contested; thus questions remain about whether, when and how to raise the topic of IPV and what to offer. Two major anxieties surfaced: a practical concern in terms of interrupting a streamlined abortion service that suits the majority of staff and patients, and a conceptual concern about risk of stigmatising abortion seekers as 'victims in crisis'. Thus, our findings indicate: when integrating IPV interventions into abortion services, local context, the integrity of separate pathways, and women's safety and agency must be considered, especially when abortion rights are under attack. Novel approaches are required and should be researched. Copyright © 2016 Elsevier Inc. All rights reserved.

    Full Text Available The Internet of Things (IoT allows machines and devices in the world to connect with each other and generate a huge amount of data, which has a great potential to provide useful knowledge across service domains. Combining the context of IoT with semantic technologies, we can build integrated semantic systems to support semantic interoperability. In this paper, we propose an integrated semantic service platform (ISSP to support ontological models in various IoT-based service domains of a smart city. In particular, we address three main problems for providing integrated semantic services together with IoT systems: semantic discovery, dynamic semantic representation, and semantic data repository for IoT resources. To show the feasibility of the ISSP, we develop a prototype service for a smart office using the ISSP, which can provide a preset, personalized office environment by interpreting user text input via a smartphone. We also discuss a scenario to show how the ISSP-based method would help build a smart city, where services in each service domain can discover and exploit IoT resources that are wanted across domains. We expect that our method could eventually contribute to providing people in a smart city with more integrated, comprehensive services based on semantic interoperability.

Combining the context of IoT with semantic technologies, we can build integrated semantic systems to support semantic interoperability. In this paper, we propose an integrated semantic service platform (ISSP) to support ontological models in various IoT-based service domains of a smart city. In particular, we address three main problems for providing integrated semantic services together with IoT systems: semantic discovery, dynamic semantic representation, and semantic data repository for IoT resources. To show the feasibility of the ISSP, we develop a prototype service for a smart office using the ISSP, which can provide a preset, personalized office environment by interpreting user text input via a smartphone. We also discuss a scenario to show how the ISSP-based method would help build a smart city, where services in each service domain can discover and exploit IoT resources that are wanted across domains. We expect that our method could eventually contribute to providing people in a smart city with more integrated, comprehensive services based on semantic interoperability.

    The continuity of care for people with neurological conditions in a remote northwest Queensland town as services are currently only available intermittently. Mixed methods design using questionnaires and staff review of the program and processes. Intermittent community rehabilitation service for clients with neurological conditions has been offered in Mount Isa and is supported by a similar fulltime service in Townsville. Both services use a unique client-centred, student-assisted, interprofessional model of care. Understanding participant experiences by obtaining feedback from clients, students and allied health professionals (AHPs) regarding their experiences of using telehealth in this setting. Previous clients of the North West Community Rehabilitation service were offered a review assessment using telehealth by an interprofessional team. Using telehealth enabled the client, remote AHP and students in Mount Isa to be connected to expert assistance in Townsville. The findings suggest that telehealth was useful in a community rehabilitation setting to provide review services for clients. This improved continuity of care for these clients because without this telehealth assessment, the clients would have had to wait up to 12 months for the next service period in Mount Isa or travel to a major urban centre to access a similar service. Feedback from clients, students and AHPs was positive; however, some challenges were identified. Recommendations for future service delivery using telehealth are outlined in the paper. © 2015 National Rural Health Alliance Inc.

  12. Does service integration improve the sexual and reproductive healthcare of women living with HIV?

    Science.gov (United States)

    Wielding, S; Flynn, B

    2016-10-01

    The sexual and reproductive health (SRH) care needs of a cohort of HIV-positive women were studied pre- and post-integration of genitourinary medicine (GUM) and SRH services. Pre-integration, 24.9% of women at risk of pregnancy were using an effective method of contraception, with a non-significant improvement post-integration to 39.3%. Pre-integration, 47.6% of pregnancies were unplanned, whilst 50% were still unplanned post-integration. Cervical cytology uptake within the previous 12 months improved significantly. It appears that the integration of services alone does not improve all aspects of the SRH of women living with HIV and additional novel strategies should be explored.

    Science.gov (United States)

    García-Valls, Marisol; Touahria, Imad Eddine

    2017-06-08

    Medical and eHealth systems are progressively realized in the context of standardized architectures that support safety and ease the integration of the heterogeneous (and often proprietary) medical devices and sensors. The Integrated Clinical Environment (ICE) architecture appeared recently with the goal of becoming a common framework for defining the structure of the medical applications as concerns the safe integration of medical devices and sensors. ICE is simply a high level architecture that defines the functional blocks that should be part of a medical system to support interoperability. As a result, the underlying communication backbone is broadly undefined as concerns the enabling software technology (including the middleware) and associated algorithms that meet the ICE requirements of the flexible integration of medical devices and services. Supporting the on line composition of services in a medical system is also not part of ICE; however, supporting this behavior would enable flexible orchestration of functions (e.g., addition and/or removal of services and medical equipment) on the fly. iLandis one of the few software technologies that supports on line service composition and reconfiguration, ensuring time-bounded transitions across different service orchestrations; it supports the design, deployment and on line reconfiguration of applications, which this paper applies to service-based eHealth domains. This paper designs the integration between ICE architecture and iLand middleware to enhance the capabilities of ICE with on line service composition and the time-bounded reconfiguration of medical systems based on distributed services. A prototype implementation of a service-based eHealth system for the remote monitoring of patients is described; it validates the enhanced capacity of ICE to support dynamic reconfiguration of the application services. Results show that the temporal cost of the on line reconfiguration of the eHealth application is bounded

    This paper addresses the optimization of structural health monitoring(SHM) before its implementation on the basis of its Value of Information (VoI). The approach for the quantification of the value of SHM builds upon a service life cost assessment and generic structural performance model...... in the framework of the Bayesian pre-posterior decision theory as the difference between the expected service-life costs considering an optimal structural integrity management and the service life costs utilizing an optimal SHM system and structural integrity management. With an example the application...... of the approach is shown and the value of the monitoring period optimized SHM information is determined....

  17. Steam generator tubes integrity: In-service-inspection

    Energy Technology Data Exchange (ETDEWEB)

    Comby, R.J. [EDF/GDL, Saint Denis (France)

    1997-02-01

    The author`s approach to tube integrity is in terms of looking for flaws in tubes. The basis for this approach is that no simple rules can be fixed to adopt a universal inspection methodology because of various concepts related to experience, leak acceptance, leak before break approach, etc. Flaw specific management is probably the most reliable approach as a compromise between safety, availability and economic issues. In that case, NDE capabilities have to be in accordance with information required by structural integrity demonstration. The author discusses the types of probes which can be used to search for flaws in addition to the types of flaws which are being sought, with examples of specific analysis experiences. The author also discusses the issue of a reporting level as it relates to avoiding false calls, classifying faults, and allowing for automation in analysis.

  20. The Linked Response: Lessons Emerging from Integration of HIV and Reproductive Health Services in Cambodia

    Directory of Open Access Journals (Sweden)

    Joanna White

    2013-01-01

    Full Text Available A qualitative assessment was made of service provider and user perceptions of the quality of integrated reproductive health services established through a pilot intervention in Cambodia. The intervention aimed to promote pregnant women's HIV testing and general utilization of reproductive health facilities as well as improve the follow-up of HIV-positive women and exposed infants through strengthened referral and operational linkages amongst health facilities/services and community-based support interventions for PLHIV. The study was conducted in one operational district where the intervention was piloted and for comparative purposes in a district where integrated services had yet to be implemented. Service providers in the pilot district reported improved collaboration and coordination of services, more effective referral, and the positive impact of improved proximity of HIV testing through integrated local level facilities. Community-based support teams for PLHIV embraced their expanded role, were valued by families receiving their assistance, and were understood to have had an important role in referral, PMTCT follow-up and countering PLHIV stigmatization; findings which underscore the potential role of community support in integrated service provision. Challenges identified included stigmatization of PLHIV by health staff at district hospital level and a lack of confidence amongst non-specialized health staff when managing deliveries by HIV-positive women, partly due to fear of HIV transmission.

  1. Integrating refugee and host health services in West Nile districts, Uganda.

    Science.gov (United States)

    Orach, Christopher Garimoi; De Brouwere, Vincent

    2006-01-01

    Refugees are a common feature in Africa and Uganda is no exception. However, Uganda does not have the resources to provide health care to all its own citizens, let alone to refugees. Refugee health services are therefore usually set up and provided separately by international organizations such as the United Nations High Commissioner for Refugees (UNHCR). However, such services often end up being the only available or reliable services in a particular location for both host and refugee populations. Yet the host populations are often denied access to these services because, in theory, other services are being provided by their government. The case study in the West Nile region of Uganda describes how host and refugee services were integrated in an attempt to address the concerns of inequity of access to care for host populations, when reasonably good health services were available to nearby refugee populations. The paper identifies and discusses the challenges encountered and those remaining.

    2014-01-01

    Sharing and integrating Remote Sensing (RS) and Geographic Information System/Science (GIS) models are critical for developing practical application systems. Facilitating model sharing and model integration is a problem for model publishers and model users, respectively. To address this problem, a framework based on a Web service for sharing and integrating RS and GIS models is proposed in this paper. The fundamental idea of the framework is to publish heterogeneous RS and GIS models into standard Web services for sharing and interoperation and then to integrate the RS and GIS models using Web services. For the former, a "black box" and a visual method are employed to facilitate the publishing of the models as Web services. For the latter, model integration based on the geospatial workflow and semantic supported marching method is introduced. Under this framework, model sharing and integration is applied for developing the Pearl River Delta water environment monitoring system. The results show that the framework can facilitate model sharing and model integration for model publishers and model users.

    Full Text Available The learning management platforms (LMS as Dot LRN (.LRN have been widely disseminated and used as a teaching tool. However, despite its great potential, most of these platforms do not allow easy integration of common services on the Web. Integration of external resources in LMS is critical to extend the quantity and quality of educational services LMS. This article presents a set of criteria and architectural guidelines for the integration of Web resources for e-learning in the LRN platform. To this end, three steps are performed: first; the possible integration technologies to be used are described, second; the Web resources that provide educational services and can be integrated into LMS platforms are analyzed, finally; some architectural aspects of the relevant platform are identified for integration. The main contributions of this paper are: a characterization of Web resources and educational services available today on the Web; and the definition of criteria and guidelines for the integration of Web resources to .LRN.

    Integrating voluntary HIV counselling and testing (VCT) with family planning and other reproductive health services may be one effective strategy for expanding VCT service delivery in resource poor settings. Using 30,257 VCT client records with linked facility characteristics from Ethiopian non-governmental, non-profit, reproductive health clinics, we constructed multi-level logistic regression models to examine associations between HIV and family planning service integration modality and three outcomes: VCT client composition, client-initiated HIV testing and client HIV status. Associations between facility HIV and family planning integration level and the likelihood of VCT clients being atypical family planning client-types, versus older (at least 25 years old), ever-married women were assessed. Relative to facilities co-locating services in the same compound, those offering family planning and HIV services in the same rooms were 2-13 times more likely to serve atypical family planning client-types than older, ever-married women. Facilities where counsellors jointly offered HIV and family planning services and served many repeat family planning clients were significantly less likely to serve single clients relative to older, married women. Younger, single men and older, married women were most likely to self-initiate HIV testing (78.2 and 80.6% respectively), while the highest HIV prevalence was seen among older, married men and women (20.5 and 34.2% respectively). Compared with facilities offering co-located services, those integrating services at room- and counsellor-levels were 1.9-7.2 times more likely to serve clients initiating HIV testing. These health facilities attract both standard material and child health (MCH) clients, who are at high risk for HIV in these data, and young, single people to VCT. This analysis suggests that client types may be differentially attracted to these facilities depending on service integration modality and other facility

    Rural labor service economy is a method turning rural surplus human resources to economic resources,to realize increase of social wealth. Developing the rural labor service economy has profound influence on promoting transfer and employment of rural surplus labor,and speeding up industrialization and urbanization. Rural labor service economy is a huge and complex systematic project for promoting urban and rural integrated development and increasing farmers’ income. This paper firstly analyzed importance and urgency of accelerating the development of rural labor service economy. From the perspective of urban and rural integration,it came up with pertinent recommendations,including establishing security mechanism and improving rural labor security mechanism,creating preferential conditions and encouraging farmers to return to hometown,exploring potential and promoting nearby labor transfer to promote rapid economic development,improving public employment service system,and cultivating and developing labor market. It is expected to provide certain references.

    Davis, G L; Boulger, J G; Hovland, J C; Hoven, N T

    2007-07-01

    Mental health care shortages in rural areas have resulted in the majority of services being offered through primary medical care settings. The authors argue that a paradigm shift must occur so that those in need of mental health care have reasonable, timely access to these services. Changes proposed include integrating mental health services into primary medical care settings, moving away from the traditional view of mental health care services (one therapist, one hour, and one client), and increasing the consultative role of psychologists and other mental health care providers in primary medical care. Characteristics of mental health providers that facilitate effective integration into primary medical care are presented. The results of a needs assessment survey and an example of a telemental health project are described. This project involved brief consultations with patients and their physicians from a shared care model using a broadband internet telecommunications link between a rural clinic and mental health service providers in an urban area.

    Seamless data-model integration is usually difficult due to the heterogeneity of the entities (i.e., data and model). These heterogeneities arise from different usages of variable names, units, tempo-spatial property, file formant and programming language. Semantic web technology provides an opportunity to lower the interoperability barrier of data-model integration by enriching the semantics of each entity. In this study, we show an example of seamlessly coupling Model-as-a-Service (MaaS) and Data-as-a-Service (DaaS) by using the micro-services developed in the Geo-Semantic project supported by NSF Earthcube program. The goal of the Geo-Semantic poject is to develop a set of micro-services, which are rooted in the semantic web technology, to couple the heterogeneous data and model. The considered MaaS and DaaS in this application are the web service models developed by adopting the Basic Model Interfaces and Clowder (an online data repository), respectively. Through the Geo-Semantic micro-services, we are able to enrich the semantics of data in Clowder by using the Semantic Annotation Service, find the data file required for the input of the model by using the Knowledge Discovery Service, and transform the data file into the required format for the model's input by using the Resource Alignment Service. The entire orchestration is performed in Experimental Modeling Environment for Linking and Interoperability - Web Application, a web application for integrating the BMI-enabled web service TopoFlow components and Clowder-supported data from Intensely Managed Landscapes Critical Zone Observatory (IMLCZO). We demonstrate that it is possible to efficiently achieve seamless data-model integration by using the Geo-Semantic architecture, therefore potentially saving scientists huge amounts of time in data preparation for models.

  11. A systematic review of integrated working between care homes and health care services

    Science.gov (United States)

    2011-01-01

    Background In the UK there are almost three times as many beds in care homes as in National Health Service (NHS) hospitals. Care homes rely on primary health care for access to medical care and specialist services. Repeated policy documents and government reviews register concern about how health care works with independent providers, and the need to increase the equity, continuity and quality of medical care for care homes. Despite multiple initiatives, it is not known if some approaches to service delivery are more effective in promoting integrated working between the NHS and care homes. This study aims to evaluate the different integrated approaches to health care services supporting older people in care homes, and identify barriers and facilitators to integrated working. Methods A systematic review was conducted using Medline (PubMed), CINAHL, BNI, EMBASE, PsycInfo, DH Data, Kings Fund, Web of Science (WoS incl. SCI, SSCI, HCI) and the Cochrane Library incl. DARE. Studies were included if they evaluated the effectiveness of integrated working between primary health care professionals and care homes, or identified barriers and facilitators to integrated working. Studies were quality assessed; data was extracted on health, service use, cost and process related outcomes. A modified narrative synthesis approach was used to compare and contrast integration using the principles of framework analysis. Results Seventeen studies were included; 10 quantitative studies, two process evaluations, one mixed methods study and four qualitative. The majority were carried out in nursing homes. They were characterised by heterogeneity of topic, interventions, methodology and outcomes. Most quantitative studies reported limited effects of the intervention; there was insufficient information to evaluate cost. Facilitators to integrated working included care home managers' support and protected time for staff training. Studies with the potential for integrated working were longer in

    Georeferenced datasets are currently actively used for modeling, interpretation and forecasting of climatic and ecosystem changes on different spatial and temporal scales. Due to inherent heterogeneity of environmental datasets as well as their huge size (up to tens terabytes for a single dataset) a special software supporting studies in the climate and environmental change areas is required. An approach for integrated analysis of georefernced climatological data sets based on combination of web and GIS technologies in the framework of spatial data infrastructure paradigm is presented. According to this approach a dedicated data-processing web system for integrated analysis of heterogeneous georeferenced climatological and meteorological data is being developed. It is based on Open Geospatial Consortium (OGC) standards and involves many modern solutions such as object-oriented programming model, modular composition, and JavaScript libraries based on GeoExt library, ExtJS Framework and OpenLayers software.

    Full Text Available Abstract Background The complexity and inter-related nature of biological data poses a difficult challenge for data and tool integration. There has been a proliferation of interoperability standards and projects over the past decade, none of which has been widely adopted by the bioinformatics community. Recent attempts have focused on the use of semantics to assist integration, and Semantic Web technologies are being welcomed by this community. Description SADI - Semantic Automated Discovery and Integration - is a lightweight set of fully standards-compliant Semantic Web service design patterns that simplify the publication of services of the type commonly found in bioinformatics and other scientific domains. Using Semantic Web technologies at every level of the Web services "stack", SADI services consume and produce instances of OWL Classes following a small number of very straightforward best-practices. In addition, we provide codebases that support these best-practices, and plug-in tools to popular developer and client software that dramatically simplify deployment of services by providers, and the discovery and utilization of those services by their consumers. Conclusions SADI Services are fully compliant with, and utilize only foundational Web standards; are simple to create and maintain for service providers; and can be discovered and utilized in a very intuitive way by biologist end-users. In addition, the SADI design patterns significantly improve the ability of software to automatically discover appropriate services based on user-needs, and automatically chain these into complex analytical workflows. We show that, when resources are exposed through SADI, data compliant with a given ontological model can be automatically gathered, or generated, from these distributed, non-coordinating resources - a behaviour we have not observed in any other Semantic system. Finally, we show that, using SADI, data dynamically generated from Web services

    Full Text Available Curriculum integration is one of the main factors in the teachers’ decision-making process when deciding to use games in formal educational contexts. Based on this observation, we aim to introduce pre-service teachers to Game Based Learning (GBL and Serious Games (SG integration in the curriculum. The teaching experience aims to facilitate different approaches to GBL and SG integration in the curriculum, including three types of GBL activities. Firstly, the use of Serious Games (SG, designed for educational purposes from the start; secondly, the game creation as a learning activity through game authoring platforms; thirdly, the use of repurposed entertainment games, which, despite not having being intentionally designed for educational purposes, could be diverted for meeting the curriculum objectives of primary education. A group of 51 pre-service teachers participated in the teaching experience during which they selected a GBL activity among the three types of GBL and SG integration in the curriculum. Most of the teachers succeed to identify SG created for educational purposes, and we observed 6 entertainment games repurposed for educational objectives, none of the pre-service teachers decided to integrate a game creation activity in the curriculum. We analyze the results of the teaching pre-service experience and the opportunities to introduce GBL and SG in pre-service teachers’ education.

    Full Text Available Objective: To examine the level of service integration within Maryland hospitals and service differentiation across the hospital system or network and its affect on heart failure patient clinical and economic outcomes. Data sources/Study setting: Maryland Health Services Cost Review Commission Inpatient Data for 1997 and 1998 were used for secondary data analysis. Study design: Retrospective cross sectional. Independent variables were the level of service integration and differentiation created from the 1998 American Hospital Association Annual Survey based on the work of Bazzoli et al. [1]. The primary dependent variables were readmission, in-hospital mortality, length of stay and costs. Data collection/Extraction methods: Patients discharged from Maryland hospitals with a diagnosis that grouped to DRG 127 (heart failure were extracted. Multivariate linear and logistic models clustered by hospital were used to analyse results at the patient level. Principal findings: A higher likelihood of readmission was found as the level of Community Differentiation increased. Although costs were higher as Total Differentiation increased in 1998, these results were not validated by 1997 data. No significant relationship was found between integration of services and outcomes. Conclusions: Similar outcomes were achieved regardless of the level of service integration or differentiation. Community hospitals produce similar patient outcomes at the same cost for this diagnosis.

    Integrating service in a post-licensure registered nurse to bachelor of science in nursing (RN to BSN) program provides licensed registered nurse (RN) students the opportunity to learn, develop, and experience different cultures while serving the community and populations in need (McKinnon & Fitzpatrick, 2012). Service to the community, integrated with academic learning can be applied in a wide variety of settings, including schools, universities, and community faith-based organizations. Academic service-learning (ASL) can involve a group of students, a classroom, or an entire school. In the RN to BSN program, the authors use a student-directed service learning approach that integrates service-learning throughout the curriculum. RN students are introduced to service-learning at program orientation prior to the start of classes and receive reinforcement and active engagement throughout the curriculum. The students and volunteer agencies receive and give benefits from the services provided and the life lessons gained through mentorship, education, and hands-on experiences.

    Currently there are two approaches to provide Quality of Service (QoS) in the next generation Internet: An early one is the Integrated Services (IntServ) with the goal of allowing end-to-end QoS to be provided to applications; the other one is the Differentiated Services (DiffServ) architecture providing QoS in the backbone. In this context, a DiffServ network may be viewed as a network element in the total end-to-end path. The objective of this paper is to investigate the possibility of providing end-to-end QoS when IntServ runs over DiffServ backbone in the next generation Internet. Our results show that the QoS requirements of IntServ applications can be successfully achieved when IntServ traffic is mapped to the DiffServ domain in next generation Internet.

    The aim of palliative medicine is to provide multidisciplinary comprehensive care in advanced illness. Patient and family utilization of various product service lines offered by the Harry R Horvitz Center for Palliative Medicine at the Cleveland Clinic Foundation was studied. Newly referred patients were followed up prospectively until 85% had either died or been lost to follow-up. Demographic, clinical, and referral data were recorded; subsequent product service line utilization was updated daily. The total study period was 171 days, and 238 patients entered. Acute care inpatient unit, outpatient clinic visits, and 24-hour phone contacts were the most frequently used product service lines. Patients had a median of 3 contacts (range, 1 to 27) with individual service lines. Multiple palliative medicine product service lines were utilized often, with repeated use of the individual service lines. A comprehensive integrated palliative medicine program is necessary to fully meet the complex needs of those with advanced disease.

    Malaria and other communicable diseases remain major threats in developing countries. In Cambodia, village malaria workers (VMWs) have been providing malaria control services in remote villages to cope with the disease threats. In 2009, the VMW project integrated child health services into the original malaria control services. However, little has been studied about the utilization of VMWs' child health services. This study aimed to identify determinants of caregivers' VMW service utilization for childhood illness and caregivers' knowledge of malaria management. A cross-sectional study was conducted in 36 VMW villages of Kampot and Kampong Thom provinces in July-September 2012. An equal number of VMW villages with malaria control services only (M) and those with malaria control plus child health services (M+C) were selected from each province. Using structured questionnaires, 800 caregivers of children under five and 36 VMWs, one of the two VMWs who was providing VMW services in each study village were interviewed. Among the caregivers, 23% in M villages and 52% in M+C villages utilized VMW services for childhood illnesses. Determinants of caregivers' utilization of VMWs in M villages included their VMWs' length of experience (AOR = 11.80, 95% confidence interval [CI] = 4.46-31.19) and VMWs' service quality (AOR = 2.04, CI = 1.01-4.11). In M+C villages, VMWs' length of experience (AOR = 2.44, CI = 1.52-3.94) and caregivers' wealth index (AOR = 0.35, CI = 0.18-0.68) were associated with VMW service utilization. Meanwhile, better service quality of VMWs (AOR = 3.21, CI = 1.34-7.66) and caregivers' literacy (AOR = 9.91, CI = 4.66-21.05) were positively associated with caregivers' knowledge of malaria management. VMWs' service quality and length of experience are important determinants of caregivers' utilization of VMWs' child health services and their knowledge of malaria management. Caregivers are seeking VMWs' support for childhood illnesses even if they are

    The impact of integrated reproductive health and HIV services on HIV testing and counseling (HTC) uptake was assessed among 882 Kenyan family planning clients using a nonrandomized cohort design within six intervention and six "comparison" facilities. The effect of integration on HTC goals (two tests over two years) was assessed using conditional logistic regression to test four "integration" exposures: a training and reorganization intervention; receipt of reproductive health and HIV services at recruitment; a functional measure of facility integration at recruitment; and a woman's cumulative exposure to functionally integrated care across different facilities over time. While recent receipt of HTC increased rapidly at intervention facilities, achievement of HTC goals was higher at comparison facilities. Only high cumulative exposure to integrated care over two years had a significant effect on HTC goals after adjustment (aOR 2.94, 95%CI 1.73-4.98), and programs should therefore make efforts to roll out integrated services to ensure repeated contact over time. © 2017 The Population Council, Inc.

    The species interaction and their biological traits (BT) determine the function of benthic communities and, hence, the delivery of ecosystem services. Therefore, disturbance of benthic communities by trawling may compromise ecosystem service delivery, including fisheries' catches. In this work, we explore 1) the impact of trawling activities on benthic functional components (after the BTA approach) and 2) how trawling impact may affect the ecosystem services delivered by benthic communities. To this aim, we assessed the provision of ecosystem services by adopting the concept of Ecosystem Service Providers (ESP), i.e. ecological units that perform ecosystem functions that will ultimately deliver ecosystem services. We studied thirteen sites subjected to different levels of fishing effort in the Mediterranean. From a range of environmental variables included in the study, we found ESPs to be mainly affected by fishing effort and grain size. Our results suggested that habitat type has significant effects on the distribution of ESPs and this natural variability influences ESP response to trawling at a specific site. In order to summarize the complex relationships between human uses, ecosystem components and the demand for ecosystem services in trawling grounds, we adapted a DPSIR (Drivers-Pressures-State Change-Impact-Response) framework to the study area, emphasizing the role of society as Drivers of change and actors demanding management Responses. This integrative framework aims to inform managers about the interactions between all the elements involved in the management of trawling grounds, highlighting the need for an integrated approach in order to ensure ecosystem service provision.

    To describe the initiation of a community pharmacy medication management service within a statewide integrated care management program. One hundred twenty-three community and community health center pharmacies in 58 counties of North Carolina. Independent and community health center pharmacies offering medication management as part of an integrated care management program to Medicaid, Medicare, dually eligible Medicare-Medicaid, and NC Health Choice beneficiaries in North Carolina. Community pharmacies joined an enhanced service network created by Community Care of North Carolina to provide medication management services as part of an integrated care management program. During the first 3 months of the program, 41% of pharmacies consistently documented the medication management services. Interviews were conducted with pharmacists from the inconsistent pharmacies to drive program improvements. Pharmacists at 73 community and community health center pharmacies were interviewed. The majority of pharmacists reported that challenges in "initiating services" and "documenting" were due to increased intensity of service and documentation compared with Medicare Part D medication therapy management requirements. Program changes to improve participation included revision of documentation requirements, authorization of technicians to transcribe pharmacists' interventions, additional documentation templates, workflow consultations, and feedback on documentation quality. Community pharmacies are capable of providing medication management integrated with care management. Some pharmacies have more difficulty initiating new services in the current workflow landscape. To facilitate implementation, it is important to minimize administrative burden and provide mechanisms for direct feedback. Pharmacy owners, managers, and leaders in pharmacy policy can use these findings to aid implementation of new services in community pharmacies. Copyright © 2016 American Pharmacists Association

    This paper seeks to address whether integrated structures are associated with more integrated forms of service. Northern Ireland has one of the most structurally integrated and comprehensive models of health and personal social services in Europe. Social and health services are jointly administered and this arrangement should, in theory, promote collaborative working and interdisciplinary arrangements. The study employed a cross-sectional survey of consultants in old age psychiatry in England and Northern Ireland. Potential respondents were sourced from the UK Royal College of Psychiatrists membership list and locally collected information. A self-administered postal questionnaire. Along with general service arrangements, the domains measured reflect core policy issues for older people's services. Under particular scrutiny in this study were the degree of integration of health and social service provision, as well as inter-professional team working. The integrated health and social care services in Northern Ireland do appear to provide more integrated patterns of working, primarily in managerial arrangements and in the location of staff. There was no evidence of the impact of integration on practice in areas such as: assessment, referral and medical screening. The factors found to be associated with greater integration of health and social care in the prediction model fell into three categories: provision of specialist services; provision of outreach activities; and shared policies by which the whole team worked. Health and personal social services in Northern Ireland have a distinct advantage over their counterparts in comparable areas of England. The results indicate that integrated structures in old age psychiatry services are associated more with integrated management systems and less with integrated practice-related activities. Further research is required on the effectiveness and cost effectiveness of integrating services in general. It is important that

  20. Graph-Based Semantic Web Service Composition for Healthcare Data Integration

    Science.gov (United States)

    2017-01-01

    Within the numerous and heterogeneous web services offered through different sources, automatic web services composition is the most convenient method for building complex business processes that permit invocation of multiple existing atomic services. The current solutions in functional web services composition lack autonomous queries of semantic matches within the parameters of web services, which are necessary in the composition of large-scale related services. In this paper, we propose a graph-based Semantic Web Services composition system consisting of two subsystems: management time and run time. The management-time subsystem is responsible for dependency graph preparation in which a dependency graph of related services is generated automatically according to the proposed semantic matchmaking rules. The run-time subsystem is responsible for discovering the potential web services and nonredundant web services composition of a user's query using a graph-based searching algorithm. The proposed approach was applied to healthcare data integration in different health organizations and was evaluated according to two aspects: execution time measurement and correctness measurement.

    Full Text Available The Next Generation Networks (NGN aims to integrate for IP-based telecominfrastructures and provide most advance & high speed emerging value added services.NGN capable to provide higher innovative services, these services will able to integratecommunication and Web service into a single platform. IP Multimedia Subsystem, aNGN leading technology, enables a variety of NGN-compliant communications servicesto interoperate while being accessed through different kinds of access networks,preferably broadband. IMS–NGN services essential by both consumer and corporateusers are by now used to access services, even communications services through the weband web-based communities and social networks, It is key for success of IMS-basedservices to be provided with efficient web access, so users can benefit from those newservices by using web-based applications and user interfaces, not only NGN-IMS UserEquipments and SIP protocol. Many Service are under planning which provided onlyunder convergence of IMS & Web 2.0. Convergence between Web 2.0 and NGN-IMScreates and serves new invented innovative, entertainment and information appealing aswell as user centric services and applications. These services merge features from WWWand Communication worlds. On the one hand, interactivity, ubiquity, social orientation,user participation and content generation, etc. are relevant characteristics coming fromWeb 2.0 services. Parallel IMS enables services including multimedia telephony, mediasharing (video-audio, instant messaging with presence and context, online directory,etc. all of them applicable to mobile, fixed or convergent telecom networks. With thispaper, this paper brings out the benefits of adopting web 2.0 technologies for telecomservices. As the services are today mainly driven by the user's needs, and proposed theconcept of unique customizable service interface.

    2008-05-01

    Early Support (ES) is the flagship government programme aimed at improving multi-agency working with, and supporting enhanced outcomes for, children with a disability 0-3 years and their families. This paper draws on results from the recently completed Department for Education and Skills commissioned national evaluation of ES involving 46 pathfinder projects throughout England. Data were collected by survey at two points in time (9 months apart), by focus groups with service providers and parents, and through secondary data analyses, including exploratory economic evaluation. This paper outlines some of the key findings pertaining to the relationship between integrated children's services and the impact of ES. As such, we address three concerns: what the evidence from ES can tell us about the relationships between universal and targeted provision within integrated children's service structures, the relationship between specific short-term initiatives and their longer-term sustainability within integrated children's services structures and the potential costs and benefits of ES looking forward to its implementation on a national basis within an integrated children's services environment. Although focused primarily on children with a disability in the early years, implications will be drawn for the implementation of Lead Professional Guidance and the Common Assessment Framework more generically.

    Full Text Available Introduction: Family centres in Sweden are integrated services that reach all prospective parents and parents with children up to their sixth year, because of the co-location of the health service with the social service and the open pre-school. The personnel on the multi-professional site work together to meet the needs of the target group. The article explores a program theory focused on the open pre-schools at family centres. Method: A multi-case design is used and the sample consists of open pre-schools at six family centres. The hypothesis is based on previous research and evaluation data. It guides the data collection which is collected and analysed stepwise. Both parents and personnel are interviewed individually and in groups at each centre. Findings: The hypothesis was expanded to a program theory. The compliance of the professionals was the most significant element that explained why the open access service facilitated positive parenting. The professionals act in a compliant manner to meet the needs of the children and parents as well as in creating good conditions for social networking and learning amongst the parents. Conclusion: The compliance of the professionals in this program theory of open pre-schools at family centres can be a standard in integrated and open access services, whereas the organisation form can vary. The best way of increasing the number of integrative services is to support and encourage professionals that prefer to work in a compliant manner.

    Rapid changes in information processing technology have made the problems of administrative and technical planning and integration difficult. Vendor-inspired terms such as “office of the future” have created confusion rather than clarification. However, the term “information resource management” (IRM) that has evolved in the private sector has potential merit. From the idea of IRM, the authors have developed the planning concept of Integrated Medical Information Services (IMIS) as a common ad...

  8. 'Trust and teamwork matter': community health workers' experiences in integrated service delivery in India.

    Mishra, Arima

    2014-01-01

    A comprehensive and integrated approach to strengthen primary health care has been the major thrust of the National Rural Health Mission (NRHM) that was launched in 2005 to revamp India's rural public health system. Though the logic of horizontal and integrated health care to strengthen health systems has long been acknowledged at policy level, empirical evidence on how such integration operates is rare. Based on recent (2011-2012) ethnographic fieldwork in Odisha, India, this article discusses community health workers' experiences in integrated service delivery through village-level outreach sessions within the NRHM. It shows that for health workers, the notion of integration goes well beyond a technical lens of mixing different health services. Crucially, they perceive 'teamwork' and 'building trust with the community' (beyond trust in health services) to be critical components of their practice. However, the comprehensive NRHM primary health care ideology - which the health workers espouse - is in constant tension with the exigencies of narrow indicators of health system performance. Our ethnography shows how monitoring mechanisms, the institutionalised privileging of statistical evidence over field-based knowledge and the highly hierarchical health bureaucratic structure that rests on top-down communications mitigate efforts towards sustainable health system integration.

    1. INTRODUCTION Early warning systems are long living and evolving: New sensor-systems and -types may be developed and deployed, sensors will be replaced or redeployed on other locations and the functionality of analyzing software will be improved. To ensure a continuous operability of those systems their architecture must be evolution-enabled. From a computer science point of view an evolution-enabled architecture must fulfill following criteria: • Encapsulation of and functionality on data in standardized services. Access to proprietary sensor data is only possible via these services. • Loose coupling of system constituents which easily can be achieved by implementing standardized interfaces. • Location transparency of services what means that services can be provided everywhere. • Separation of concerns that means breaking a system into distinct features which overlap in functionality as little as possible. A Service Oriented Architecture (SOA) as e. g. realized in the German Indonesian Tsunami Early Warning System (GITEWS) and the advantages of functional integration on the basis of services described below adopt these criteria best. 2. SENSOR INTEGRATION Integration of data from (distributed) data sources is just a standard task in computer science. From few well known solution patterns, taking into account performance and security requirements of early warning systems only functional integration should be considered. Precondition for this is that systems are realized compliant to SOA patterns. Functionality is realized in form of dedicated components communicating via a service infrastructure. These components provide their functionality in form of services via standardized and published interfaces which could be used to access data maintained in - and functionality provided by dedicated components. Functional integration replaces the tight coupling at data level by a dependency on loosely coupled services. If the interfaces of the service providing

    Rakich, J S; Darr, K; Longest, B B

    1993-01-01

    The health services paradigm with respect to quality has shifted to that of conformance to requirements (the absence of defects) and fitness for use (meeting customer expectations and needs). This article presents an integrated model of continuous quality improvement (CQI) (often referred to as total quality management) and productivity improvement for health services organizations. It incorporates input-output theory and focuses on the CQI challenge--"How can we be certain that we do the right things right the first time, every time?" The twin pillars of CQI are presented. Achievement of both will result in productivity improvement and enhancement of the health services organization's competitive position.

  13. Integrating Into the Global Economy Through Services. The Case of Romania

    2014-04-01

    Full Text Available Services represent a most important and dynamic frontier of international trade and investment. The steady expansion of trade in services and its relative resilience in the recent crisis, coupled with its key role in global production networks and its increasing potential in attracting investment provides new opportunities for countries to grow their economies and integrate into the global economy. Drawing on insights from current literature and relying on balance of payments and trade in value-added statistics, this paper examines the main developments shaping Romania’s services trade over the post-crisis years. Its aim is to assess whether the country is grabbing the new opportunities arising from services globalization. It finds that following the dramatic crisis-induced decline in the value and performance of Romania’s services trade, the outlook is now radically improving as evidenced by the strongly rebounding services flows and net exports. Nonetheless, the country’s integration into the global economy through services flows continues to remain below its potential.

    Chin-Te Jung

    2013-01-01

    Full Text Available The lack of integration and communication of various geographic information services (GI services has resulted in many duplication collection of earth observation data, and challenges of semantic interoperability. This paper proposes an ontology-based multi-agents platform, called MAKOCI (multi-agent knowledge oriented cyberinfrastructure, which acts as GI service one stop to manage, publish, share, and discover GI services semantically. By ontologies, formal meanings of concepts are defined to annotate and discover GI services on a conceptual level for semantic interoperability. With the assistance of multi-agents, the processes in MAKOCI can be divided into various modules and be communicated based on the same semantics in ontologies. A prototype was implemented to test MAKOCI. Finally, we conclude the advantages and disadvantages of MAKOCI and point out several future works.

    Service users have lacked substantial influence, access, and participation in social work education in Norway and Sweden. In this article the author presents comparative analyses of two participatory projects that have developed and implemented practices that integrate service users into academic social work education and empower service users. The Norwegian HUSK project and the Social Work as Mobilization and Entrepreneurship course, also known as the "Mobilization course," at Lund University in Sweden demonstrate collaboration between research, social work education, and service users. The conclusions focus on the importance of the empowering processes by including recognition and dialogue, co-learning in practice, and the use of neutral venues to ensure effective user participation. The inclusion of service users in social work education can improve both practice and education.

  18. Ecosystem Services at the Landscape Scale: the Need for Integrative Approaches

    2010-01-01

    Full Text Available During the symposium “Ecosystem Services at the Landscape Scale” from the EU-IALE conference 2009, several challenges for future research on approaches to use the concept of ecosystem services at the landscape scale were identified, focussing on the need for integration. Three main research directions were discussed, (i the definition of the potentials and limitations of the ecosystem service approach for landscape analysis, (ii the identification of suitable methods and tools to apply the ecosystem service approach at the landscape scale and (iii the demand of incorporating ecosystem and landscape services in decision making and management. This paper briefly addresses and discusses some of these topics and puts them into a broader perspective. From this viewpoint it becomes obvious that many high-quality sectoral studies are carried out, e.g. concentrating on specific services or specific linkages within the “ecosystem service cascade” which describes the relation between biophysical characteristics of the landscape, their functions, services, benefits and values for society. In order to provide useful information for decision makers, ecosystem services studies should be supplemented by investigations of the whole systems of interactions between ecological processes and societal valuations.

    Low back pain (LBP) is a common, costly, and debilitating condition that creates a heavy socioeconomic burden on the global health care systems. In Western Medicine (WM), the treatment goals are to relieve pain, reduce disability, and enhance rehabilitation. In Traditional Chinese Medicine (TCM), acupuncture is frequently used to rebalance the vital energy "Qi". Whilst numerous literatures are available from WM and TCM in the management of LBP, the value of an integrative WMTCM therapy remains unknown. This article aims to introduce an integrative WM-TCM service model for LBP, which is now available at the Hong Kong Institute of Integrative Medicine, the Chinese University of Hong Kong.

    We report the results of a social validity assessment that was administered to special education service providers (N = 44) to document the acceptability and effectiveness ratings of several treatment integrity training methods. The participants judged performance feedback as the most likely method to improve their treatment integrity, followed by avoidance (negative reinforcement) of supervision meetings, online training, and financial incentive. Performance feedback was also rank-ordered as most effective among the four training methods. We discuss the merits of social validity assessment in designing programs for enhancing treatment integrity among practitioners within educational and clinical settings.

    2015-12-01

    Serviced-oriented computing provides an opportunity to couple web service models using semantic web technology. Through this approach, models that are exposed as web services can be conserved in their own local environment, thus making it easy for modelers to maintain and update the models. In integrated modeling, the serviced-oriented loose-coupling approach requires (1) a set of models as web services, (2) the model metadata describing the external features of a model (e.g., variable name, unit, computational grid, etc.) and (3) a model integration framework. We present the architecture of coupling web service models that are self-describing by utilizing a smart modeling framework. We expose models that are encapsulated with CSDMS (Community Surface Dynamics Modeling System) Basic Model Interfaces (BMI) as web services. The BMI-enabled models are self-describing by uncovering models' metadata through BMI functions. After a BMI-enabled model is serviced, a client can initialize, execute and retrieve the meta-information of the model by calling its BMI functions over the web. Furthermore, a revised version of EMELI (Peckham, 2015), an Experimental Modeling Environment for Linking and Interoperability, is chosen as the framework for coupling BMI-enabled web service models. EMELI allows users to combine a set of component models into a complex model by standardizing model interface using BMI as well as providing a set of utilities smoothing the integration process (e.g., temporal interpolation). We modify the original EMELI so that the revised modeling framework is able to initialize, execute and find the dependencies of the BMI-enabled web service models. By using the revised EMELI, an example will be presented on integrating a set of topoflow model components that are BMI-enabled and exposed as web services. Reference: Peckham, S.D.

  4. How to Integrate HIV and Sexual and Reproductive Health Services in Namibia, the Epako Clinic Case Study

    Directory of Open Access Journals (Sweden)

    Tomas Zapata

    2017-07-01

    Full Text Available Introduction: During the past two decades, HIV and Sexual and Reproductive Health services in Namibia have been provided in silos, with high fragmentation. As a consequence of this, quality and efficiency of services in Primary Health Care has been compromised.  Methods: We conducted an operational research (observational pre-post study in a public health facility in Namibia. A health facility assessment was conducted before and after the integration of health services. A person-centred integrated model was implemented to integrate all health services provided at the health facility in addition to HIV and Sexual and Reproductive Health services. Comprehensive services are provided by each health worker to the same patients over time (longitudinality, on a daily basis (accessibility and with a good external referral system (coordination. Prevalence rates of time flows and productivity were done.  Results: Integrated services improved accessibility, stigma and quality of antenatal care services by improving the provider-patient communication, reducing the time that patients stay in the clinic in 16% and reducing the waiting times in 14%. In addition, nurse productivity improved 85% and the expected time in the health facility was reduced 24% without compromising the uptake of TB, HIV, outpatient, antenatal care or first visit family planning services. Given the success on many indicators resulting from integration of services, the goal of this paper was to describe “how” health services have been integrated, the “process” followed and presenting some “results” from the integrated clinic.  Conclusions: Our study shows that HIV and SRH services can be effectively integrated by following the person-centred integrated model. Based on the Namibian experience on “how” to integrate health services and the “process” to achieve it, other African countries can replicate the model to move away from the silo approach and contribute to

    This integrative literature review aimed at identifying the characteristics and describing how teaching-service integration is expressed in studies on Pró-Saúde (Charitable institution for social and hospital assistance) published in Brazil in the period 2007-2012. For the search, the term National Professional Health Education Reorientation Program was entered in the following databases: Virtual Health Library (BVS), Google Scholar and the Bank of Theses of the Coordination for the Improvement of Higher Education Personnel (CAPES). Forty-one publications were selected with the following inclusion criteria: scientific papers; theses and dissertations; studies in English, Portuguese or Spanish. The critical review of studies was performed through a comprehensive reading of the texts. Outcomes are presented in two categories: Dialogue and partnership as tools for teaching-service integration and Movements of change in teaching-service through Pró-Saúde. Studies have shown that changes in professional education and practice are possible and necessary, especially when supported by strategies that encourage active participation of subjects and confirm teaching-service integration as opportunity for dialogue, promoted by this inducing policy.

    2012-12-01

    The paper presents a methodology that follows a top-down approach based on a Model-Driven Architecture for integrating and coordinating healthcare services through cross-organizational processes to enable organizations providing high quality healthcare services and continuous process improvements. The methodology provides a modeling language that enables organizations conceptualizing an integration agreement, and identifying and designing cross-organizational process models. These models are used for the automatic generation of: the private view of processes each organization should perform to fulfill its role in cross-organizational processes, and Colored Petri Net specifications to implement these processes. A multi-agent system platform provides agents able to interpret Colored Petri-Nets to enable the communication between the Healthcare Information Systems for executing the cross-organizational processes. Clinical documents are defined using the HL7 Clinical Document Architecture. This methodology guarantees that important requirements for healthcare services integration and coordination are fulfilled: interoperability between heterogeneous Healthcare Information Systems; ability to cope with changes in cross-organizational processes; guarantee of alignment between the integrated healthcare service solution defined at the organizational level and the solution defined at technological level; and the distributed execution of cross-organizational processes keeping the organizations autonomy.

    2007-10-01

    Full Text Available Purpose: The article summarises the process and the results of the first, integrated inspection of managed care services for people with learning disabilities in Scotland. The multi-agency model used was developed to be congruent with the existing performance inspection models, used by single agency inspection. The inspection activities and main outcomes are described, and suggestions are made for improvements. Context of case: In 2006 an inspection model was devised to assess the quality of health, social services and education services for people with learning disabilities in one geographical area of Scotland, as a precursor to a programme of inspections nationally. The first joint, integrated inspection of all services for people with learning disabilities in Scotland took place in June 2006, and the report was published in March 2007. This was the first multi-agency inspection of its kind in the UK, and the first to involve carers and people with learning disabilities on the inspection team. Data sources: A number of data sources were used to check existing practice against agreed Quality Outcome indicators. Primary sources of data were social work records, health records, education records, staff surveys, carer surveys, interviews with staff, family carers and people with learning disabilities, and self evaluations completed by the services being inspected. Eleven different domains, each with sub-indicators were investigated. Case description: This paper summarises the process of an integrated, multi-agency inspection, how the inspection activities were conducted and the main findings of this inspection. Practical improvements to the process are suggested, and these may be of use to other services and inspectorates. Conclusions and discussion: The integrated inspection was a qualified success. Most major objectives were achieved. The sharing of data amongst inspection agencies, establishing the level of commitment to integrated inspection

    Full Text Available Today the ability to seamlessly exchange information between internal business processes, customers, and partners is vital for success. The organizations employ a variety of disparate applications that store and exchange data in dissimilar ways and therefore cannot "talk" to one another productively. Web services have evolved as a practical, cost-effective, deployment environment to realize dynamic and interoperable data integration between critical applications over operating system, platform, and language barriers that were previously impossible. This paper describes a service-oriented approach for the integration of a Web Portal and ERP application. We present a system architecture based on Web Service oriented framework in which both the applications are loosely connected through software components.

    The Integrated Management of Newborn and Childhood Illness strategy equips health workers with essential knowledge and skills to effectively manage sick children with common neonatal and childhood diseases. Since in-service training is very demanding to achieve the desired coverage of training of health workers, pre-service training is taken as a solution. At the time of the survey, most public and some private health professionals' training institutions were conducting pre-service training. However, several concerns have been expressed on the training. Therefore, this survey was conducted to assess the status of pre-service Integrated Management of New-born and Childhood Illness training. A cross sectional survey on health professional training institutes/schools to evaluate pre-service Integrated Management of Newborn and Childhood Illness training was conducted in November 2007. Data was collected using pre-tested questionnaires, focused group interviews with teachers and students, observation of students while managing sick children using Integrated Management of Newborn and Childhood Illness guidelines, and reviews of pediatric course outlines and other teaching/learning materials. Data was entered in computer and analyzed using SPSS for Windows version 12.0.1. Twenty nine health professionals' training institutions (34 academic programs) which have started pre-service training were included in the survey. Of the 34 programs 22 were diploma nursing, 6 Bachelor of Sciences nursing, 4 health officer and the remaining two medicine. Thirty (88.2%) programs have integrated it in their curriculum. All academic programs had at least one fulltime staff for Integrated Management of Newborn and Childhood Illness classroom instruction. Twenty nine (85.3%) programs had staff trained in case management skills. All the 34 academic programs taught health workers skills, 28(82.3%) used mixed approach.

    As nuclear power utilities strive to stream-line their organizations, while improving outage and refurbishment project performance, the necessity for effective relationships and interaction between utility and service-providers becomes paramount. Successful integration of Service-Provider into the Utility's environment is achievable and has been demonstrated. Early and extensive engagement in front-end planning, single-point-of-continuity, and the use of integrated execution teams, are some of the critical elements for ensuring success. The paper discusses Task-Leadership Integration at the three levels of; utility executive level 'need-statement'; a 'why is this important' discussion; and as a 'thoughtful tutorial' on its features and practice.

  11. Information Integration Platform for Patient-Centric Healthcare Services: Design, Prototype and Dependability Aspects

    Directory of Open Access Journals (Sweden)

    2014-03-01

    Full Text Available Technology innovations have pushed today’s healthcare sector to an unprecedented new level. Various portable and wearable medical and fitness devices are being sold in the consumer market to provide the self-empowerment of a healthier lifestyle to society. Many vendors provide additional cloud-based services for devices they manufacture, enabling the users to visualize, store and share the gathered information through the Internet. However, most of these services are integrated with the devices in a closed “silo” manner, where the devices can only be used with the provided services. To tackle this issue, an information integration platform (IIP has been developed to support communications between devices and Internet-based services in an event-driven fashion by adopting service-oriented architecture (SOA principles and a publish/subscribe messaging pattern. It follows the “Internet of Things” (IoT idea of connecting everyday objects to various networks and to enable the dissemination of the gathered information to the global information space through the Internet. A patient-centric healthcare service environment is chosen as the target scenario for the deployment of the platform, as this is a domain where IoT can have a direct positive impact on quality of life enhancement. This paper describes the developed platform, with emphasis on dependability aspects, including availability, scalability and security.

    Full Text Available Abstract Background Use of complementary medicine is common, consumer driven and usually outpatient focused. We wished to determine interest among the medical staff at a North Carolina academic medical center in integrating diverse therapies and services into comprehensive care. Methods We conducted a cross sectional on-line survey of physicians, nurse practitioners and physician assistants at a tertiary care medical center in 2006. The survey contained questions on referrals and recommendations in the past year and interest in therapies or services if they were to be provided at the medical center in the future. Results Responses were received from 173 clinicians in 26 different departments, programs and centers. There was strong interest in offering several specific therapies: therapeutic exercise (77%, expert consultation about herbs and dietary supplements (69%, and massage (66%; there was even stronger interest in offering comprehensive treatment programs such as multidisciplinary pain management (84%, comprehensive nutritional assessment and advice (84%, obesity/healthy lifestyle promotion (80%, fit for life (exercise and lifestyle program, 76%, diabetes healthy lifestyle promotion (73%; and comprehensive psychological services for stress management, including hypnosis and biofeedback (73%. Conclusion There is strong interest among medical staff at an academic health center in comprehensive, integrated services for pain, obesity, and diabetes and in specific services in fitness, nutrition and stress management. Future studies will need to assess the cost-effectiveness of such services, as well as their financial sustainability and impact on patient satisfaction, health and quality of life.

    Full Text Available Family intervention literature on adolescent parenting describes the pathways between outcomes for adolescent mothers and their children and the contexts of the pregnancy itself (e.g., poverty, low or no prenatal care, lower educational attainment. The aim of these descriptions is often to inform intervention designs that promote adaptive functioning for the child, the mother, and the dyad. Mental health services are an important component of many of these interventions; these services may be delivered by a clinician within the organization providing the intervention, or the organization may connect mothers with external mental health services in their communities. Using in-house clinicians rather than external providers may be beneficial by decreasing the high attrition rates common to this population. Although this service delivery approach is theoretically appealing, it has not been subject to rigorous empirical evaluation. In the current randomized study, we examine outcomes for teenage mothers based on two service delivery methods: Integrated Mental Health Services (IMHS and the Standard of Care (SoC which outsources clients’ mental health needs through community referrals. Information about the effectiveness of service delivery strategies can help program providers make decisions about how best to allocate limited funds to provide effective services.

    2007-12-01

    Full Text Available Introduction: One aspect of clinical integration involves case managers' tools and particularly the individualized service plan. Methods: We examined individualized service plan content and use in the PRISMA experiment. We analyzed 50 charts, and conducted and recorded interviews regarding individualized service plan use with all the case managers concerned (n=13. Results: Delays between starting case management and writing the individualized service plan were long and varied (0–596 days, mean: 117 days. During the interviews, the individualized service plan was described as the ‘last step’ once the active planning phase was over. The reasons for formulating plans were mainly administrative. From a clinical viewpoint, individualized service plans were used as memoranda and not to describe services (842 interventions not mentioned in the plans or needs (694 active problems not mentioned. Case managers felt uncomfortable with the individualized planning task and expected a tool more adapted to their needs. Conclusion: Although a majority of the case managers' charts contained an individualized service plan, implementation of this tool seems tenuous. Because of the discrepancy between the potential usefulness expected by case managers and their actual use, a working committee was created to develop proposals for modifying the instrument.

    Full Text Available The IP multimedia subsystem (IMS is a service control overlay standardized by the 3GPP. The IMS is based on session initiation protocol (SIP to establish, modify, and terminate the sessions. It provides a clean separation between services, signaling, and media with the potential to enable control and management of services over multiple transport technologies. In the scope of fixed-mobile convergence, this paper is dedicated to presenting a review of how cable networks can be integrated into IMS technology to achieve 3G-cable horizontal convergence. Cable networks, as one of the major fixed broadband access technologies with PacketCable architecture, are able to provide broadband internet access and VoIP in addition to cable TV. In this article, we review the evolution in PacketCable architecture to take up IMS. In this way, we consider the standardization and research activities to address this integration. We review some important challenges such as SIP protocol compatibility, defining unique user profile, required enhancement in authentication process, QoS and charging system.

    The simultaneous burdens of communicable and chronic non-communicable diseases cause significant morbidity and mortality in middle-income countries. The poor are at particular risk, with lower access to health care and higher rates of avoidable mortality. Integrating health-related services with microfinance has been shown to improve health knowledge, behaviors, and access to appropriate health care. However, limited evidence is available on effects of fully integrating clinical health service delivery alongside microfinance services through large scale and sustained long-term programs. Using a conceptual model of health services access, we examine supply- and demand-side factors in a microfinance client population receiving integrated services. We conduct a case study using data from 2010 to 2012 of the design of a universal screening program and primary care services provided in conjunction with microfinance loans by Pro Mujer, a women's development organization in Latin America. The program operates in Argentina, Bolivia, Mexico, Nicaragua, and Peru. We analyze descriptive reports and administrative data for measures related to improving access to primary health services and management of chronic diseases. We find provision of preventive care is substantial, with an average of 13% of Pro Mujer clients being screened for cervical cancer each year, 21% receiving breast exams, 16% having a blood glucose measurement, 39% receiving a blood pressure measurement, and 46% having their body mass index calculated. This population, with more than half of those screened being overweight or obese and 9% of those screened having elevated glucose measures, has major risk factors for diabetes, high blood pressure, and cardiovascular disease without intervention. The components of the Pro Mujer health program address four dimensions of healthcare access: geographic accessibility, availability, affordability, and acceptability. Significant progress has been made to meet basic

  18. Integrating HIV & AIDS education in pre-service mathematics education for social justice

    2011-01-01

    Full Text Available Since 1999, many South African education policy documents have mandated integration of HIV & AIDS education in learning areas/disciplines. Policy document research has shown that although South African politicians and managers have produced volumes of eloquent and compelling legislation regarding provision for HIV & AIDS education, little of this is translated into action. The impact of HIV & AIDS permeates the social, economic and political arenas in South Africa. Integration of HIV & AIDS education across disciplines can serve as a strategy to further the ideals of social justice. This paper focuses on how integration in the teaching and learning of Mathematics Education provides opportunities to take action for social justice. The inquiry explores the following question: How can the myth that there is 'nothing we can do' about HIV & AIDS, which is linked to social justice issues, be addressed through integration of HIV & AIDS education in Mathematics pre-service teacher education? Drawing on self-study, the work of a Mathematics teacher educator who worked with pre-service teachers to integrate HIV & AIDS education at a higher education institution is described. By considering integration of HIV & AIDS education in Mathematics Education and taking action it is possible to develop strategies which directly relate to social justice.

    2010-07-01

    Web services have become widely used in bioinformatics analysis, but there exist incompatibilities in interfaces and data types, which prevent users from making full use of a combination of these services. Therefore, we have developed the TogoWS service to provide an integrated interface with advanced features. In the TogoWS REST (REpresentative State Transfer) API (application programming interface), we introduce a unified access method for major database resources through intuitive URIs that can be used to search, retrieve, parse and convert the database entries. The TogoWS SOAP API resolves compatibility issues found on the server and client-side SOAP implementations. The TogoWS service is freely available at: http://togows.dbcls.jp/.

  20. Modeling and Detecting Feature Interactions among Integrated Services of Home Network Systems

    Science.gov (United States)

    Igaki, Hiroshi; Nakamura, Masahide

    This paper presents a framework for formalizing and detecting feature interactions (FIs) in the emerging smart home domain. We first establish a model of home network system (HNS), where every networked appliance (or the HNS environment) is characterized as an object consisting of properties and methods. Then, every HNS service is defined as a sequence of method invocations of the appliances. Within the model, we next formalize two kinds of FIs: (a) appliance interactions and (b) environment interactions. An appliance interaction occurs when two method invocations conflict on the same appliance, whereas an environment interaction arises when two method invocations conflict indirectly via the environment. Finally, we propose offline and online methods that detect FIs before service deployment and during execution, respectively. Through a case study with seven practical services, it is shown that the proposed framework is generic enough to capture feature interactions in HNS integrated services. We also discuss several FI resolution schemes within the proposed framework.
