    OpenAIRE

    Perri, Richard.

    1999-01-01

    During the mid 90s, data and voice began to merge, propelled by advances in compression technology. The ubiquity of routed Internet Protocol (IP) networks, and the desire to trim telephony costs are the major driving forces of the deployment of Voice over IP (VoIP). One advantage of VoIP technologies is that they leverage existing network resources and dramatically reduce, or major eliminate telephone costs. If there is an existing Wide Area Network (WAN) then VoIP could be employed over the ...

  2. Voice and Video Telephony Services in Smartphone

    Directory of Open Access Journals (Sweden)

    2006-01-01

    Full Text Available Multimedia telephony is a delay-sensitive application. Packet losses, relatively less critical than delay, are allowed up to a certain threshold. They represent the QoS constraints that have to be respected to guarantee the operation of the telephony service and user satisfaction. In this work we introduce a new smartphone architecture characterized by two process levels called application processor (AP and mobile termination (MT, respectively. Here, they communicate through a serial channel. Moreover, we focus our attention on two very important UMTS services: voice and video telephony. Through a simulation study the impact of voice and video telephony is evaluated on the structure considered using the protocols known at this moment to realize voice and video telephony

  4. A Stepwise Approach to Developing Languages for SIP Telephony Service Creation

    DEFF Research Database (Denmark)

    Palix, Nicolas; Consel, Charles; Reveillere, Laurent

    2007-01-01

    Developing a SIP-based telephony service requires a programmer to have expertise in telephony rules and constraints, the SIP protocol, distributed systems, and a SIP API, which is often large and complex. These requirements make the development of telephony software an overwhelming challenge...... a scripting language dedicated to the development of telephony services. This approach enables critical properties of services to be guaranteed and captures expertise on the operational behavior of a service. We have applied this approach to developing the Session Processing Language (SPL) dedicated to SIP...

  5. Speech Perception Benefits of Internet Versus Conventional Telephony for Hearing-Impaired Individuals

    Science.gov (United States)

    Dubach, Patrick; Pfiffner, Flurin; Kompis, Martin; Caversaccio, Marco

    2012-01-01

    Background Telephone communication is a challenge for many hearing-impaired individuals. One important technical reason for this difficulty is the restricted frequency range (0.3–3.4 kHz) of conventional landline telephones. Internet telephony (voice over Internet protocol [VoIP]) is transmitted with a larger frequency range (0.1–8 kHz) and therefore includes more frequencies relevant to speech perception. According to a recently published, laboratory-based study, the theoretical advantage of ideal VoIP conditions over conventional telephone quality has translated into improved speech perception by hearing-impaired individuals. However, the speech perception benefits of nonideal VoIP network conditions, which may occur in daily life, have not been explored. VoIP use cannot be recommended to hearing-impaired individuals before its potential under more realistic conditions has been examined. Objective To compare realistic VoIP network conditions, under which digital data packets may be lost, with ideal conventional telephone quality with respect to their impact on speech perception by hearing-impaired individuals. Methods We assessed speech perception using standardized test material presented under simulated VoIP conditions with increasing digital data packet loss (from 0% to 20%) and compared with simulated ideal conventional telephone quality. We monaurally tested 10 adult users of cochlear implants, 10 adult users of hearing aids, and 10 normal-hearing adults in the free sound field, both in quiet and with background noise. Results Across all participant groups, mean speech perception scores using VoIP with 0%, 5%, and 10% packet loss were 15.2% (range 0%–53%), 10.6% (4%–46%), and 8.8% (7%–33%) higher, respectively, than with ideal conventional telephone quality. Speech perception did not differ between VoIP with 20% packet loss and conventional telephone quality. The maximum benefits were observed under ideal VoIP conditions without packet loss and

    CERN Document Server

    Pohančeník, Martin; Segeč, Pavel

    The purpose of this diploma thesis was to design and implement a system that would provide an interface of CERN’s telephony network for Voice over IP services (SIP-based services specifically). This system thus serves as an entry point for calls originating from outside of CERN’s telephony network and enables users of these services to call CERN’s fixed and mobile phone numbers. The theoretical part of the thesis talks in detail about the project specification and describes the goals that were trying to be achieved. It also describes the topic of VoIP telephony and current trends, alongside with analysis of the current telephone network of CERN. The practical part is targeted to explain the design of the solution and deployment of the system at CERN. The final part of the thesis shows testing scenarios and results and states several extension capabilities.

  8. Security of IP Telephony in Ecuador: Online Analysis

    Directory of Open Access Journals (Sweden)

    2016-06-01

    Full Text Available Telephony is a global service and thus telephone networks have been a coveted target for criminals. Now that voice can be transported over IP and that multiple services are integrated in a convergent model through Internet, there are more incentives to attack and more attackers. Moreover, the development of open source telephone applications has encouraged the massive use of IP telephony, but not an increased awareness about embedded security risks. Due to the current and intensive adoption of IP telephony systems in Ecuador, we conducted an exploration based on public information to obtain statistics about telephone systems connected to Internet in Ecuador. Additionally, using a deliberately vulnerable IP telephony system, we collected more data to do a preliminary analysis of threats to such systems. We found that hundreds of telephone systems were publicly available on the Internet and using outdated versions of Asterisk-based applications. We also found thousands of malicious interactions on the IP telephony system we deployed on the Internet.

    1999-11-01

    The recent interest in IP telephony has led to a tremendous increase of standardization activities in the area. The three main standards bodies in the area of IP telephony are the International Telecommunication Union's (ITU-T) Study Group (SG) 16, the Internet Engineering Task Force (IETF) and the European Telecommunication Standards Institute's (ETSI) TIPHON project. In addition, forums such as the International Multimedia Teleconferencing Consortium (IMTC), the Intelligent Network Forum (INF), the International Softswitch Consortium (ISC), the Electronic Computer Telephony Forum (ECTF), and the MIT's Internet Telephony Consortium (ITC) are looking into various other aspects that aim at the growth of this industry. This paper describes the main tasks (completed and in progress) undertaken by these organizations. In describing such work, an overview of the underlying technology is also provided.

    CERN Multimedia

    CERN. Geneva

    2015-01-01

    The heart of CERN’s telephony infrastructure consists of the Alcatel IP-PBX that links CERN’s fixed line phones, Lync softphones and CERN’s GSM subscribers to low-cost local and international telephony services. The PABX infrastructure also supports the emergency “red telephones” in the LHC tunnel and provides vital services for the Fire and Rescue Service and the CERN Control Centre. Although still reliable, the Alcatel hardware is increasingly costly to maintain and looking increasingly outmoded in a market where open source solutions are increasingly dominant. After presenting an overview of the Alcatel PABX and the services it provides, including innovative solutions such as the Closed User Group for our mobile telephony services, we present a possible architecture for a software based system designed to meet tomorrow’s communication needs and describe how the introduction of open-source call routers based on the SIP protocol and Session Border Controllers (SBC) could foster the introduction...

    Full Text Available OBJECTIVE: To analyze speech reading through Internet video calls by profoundly hearing-impaired individuals and cochlear implant (CI users. METHODS: Speech reading skills of 14 deaf adults and 21 CI users were assessed using the Hochmair Schulz Moser (HSM sentence test. We presented video simulations using different video resolutions (1280 × 720, 640 × 480, 320 × 240, 160 × 120 px, frame rates (30, 20, 10, 7, 5 frames per second (fps, speech velocities (three different speakers, webcameras (Logitech Pro9000, C600 and C500 and image/sound delays (0-500 ms. All video simulations were presented with and without sound and in two screen sizes. Additionally, scores for live Skype™ video connection and live face-to-face communication were assessed. RESULTS: Higher frame rate (>7 fps, higher camera resolution (>640 × 480 px and shorter picture/sound delay (<100 ms were associated with increased speech perception scores. Scores were strongly dependent on the speaker but were not influenced by physical properties of the camera optics or the full screen mode. There is a significant median gain of +8.5%pts (p = 0.009 in speech perception for all 21 CI-users if visual cues are additionally shown. CI users with poor open set speech perception scores (n = 11 showed the greatest benefit under combined audio-visual presentation (median speech perception +11.8%pts, p = 0.032. CONCLUSION: Webcameras have the potential to improve telecommunication of hearing-impaired individuals.

    Full Text Available A research and development (R&D approach has been applied to video telephony (VT in northern Finland since 1994 by broad consortia. The focus has been on the considerable involvement of ergonomics within the engineering and implementation of VT. This multidisciplinary participatory ergonomic R&D approach (PERDA is described briefly, in general and through two cases. The user-centeredness should be discernible in this sociotechnical systemic entity. A consortium—comprising mainly manufacturers, individual and organizational users of technological products, and R&D organizations—serves as a natural context for product development. VT has been considered to have much potential for enhancing (multimedia interaction and effective multimodal communication, thereby facilitating many activities of everyday life and work. An assessment of the VT system, called HomeHelper, involved older citizens, as clients or customers, and the staff of social, health, and other services.

    There is an ongoing debate about the possibility of adverse health effects related to radiofrequency (RF) radiation exposure from mobile phones and their associated base stations. Of particular public concern in this context are children. In its report the Independent Expert Group on Mobile Phones (IEGMP) recommended that the widespread use of mobile phones by children should be discouraged citing that children may be more vulnerable because of their developing nervous system, their greater absorption of energy in the tissue of the head and a longer lifetime of exposure. However, more recently the Health Council of the Netherlands disagreed with the IEGMP and concluded that there is no convincing scientific data to restrict children from using mobile phones. The World Health Organization states that none of there centre views have found that exposure to the RF fields form mobile phones or their base stations causes any adverse health consequence. However there has been limited scientific research specifically focussed on children. Future research will be required to address the issue of mobile telephony and children.

  3. Digital telephony and network integration

    CERN Document Server

    Keiser, Bernhard E

    1995-01-01

    What is "digital telephony"? To the authors, the term digital telephony denotes the technology used to provide a completely digital telecommunication system from end-to-end. This implies the use of digital technology from one end instru­ ment through transmission facilities and switching centers to another end instru­ ment. Digital telephony has become possible only because of the recent and on­ going surge of semiconductor developments, allowing microminiaturization and high reliability along with reduced costs. This book deals with both the future and the present. Thus, the first chapter is entitled, "A Network in Transition." As baselines, Chapters 2 and 11 provide the reader with the present status of teler-hone technology in terms of voice digiti­ zation as well as switching principles. The book is an outgrowth of the authors' consulting and teaching experience in the field since the early 1980s. The book has been written to provide both the engineering student and the practicing engineer a working k...

    Science.gov (United States)

    Huang, B. Q.; Kechadi, M.-T.; Buckley, B.

    Although churn prediction has been an area of research in the voice branch of telecommunications services, more focused studies on the huge growth area of Broadband Internet services are limited. Therefore, this paper presents a new set of features for broadband Internet customer churn prediction, based on Henley segments, the broadband usage, dial types, the spend of dial-up, line-information, bill and payment information, account information. Then the four prediction techniques (Logistic Regressions, Decision Trees, Multilayer Perceptron Neural Networks and Support Vector Machines) are applied in customer churn, based on the new features. Finally, the evaluation of new features and a comparative analysis of the predictors are made for broadband customer churn prediction. The experimental results show that the new features with these four modelling techniques are efficient for customer churn prediction in the broadband service field.

  8. QoS Predictability of Internet Services

    Science.gov (United States)

    Bilski, Tomasz

    The paper presents problems of QoS (Quality of Service) predictability of network services (mainly in WAN environment). In the first part we present general remarks on QoS predictability problem, mentioning some research projects and available resources. The main part of the paper deals with QoS predictability in long-term as well as short-term viewpoints. We will try to answer a question: is it possible to predict network QoS/performance level with a use of statistical data from the past? The term quality of service has many meanings ranging from the user's qualitative perception of the service to a set of quantitative connection parameters (RTT (Round Trip Time), throughput, loss packet rate) necessary to achieve particular service quality. In the paper we will mostly use the second meaning of the term based on RFC 2386 [1]. Analyzed, statistical data on Internet performance are taken from the IEPM (Internet End-to-end Performance Measurement) database.

  6. Current experiences with internet telepathology and possible evolution in the next generation of Internet services.

    Science.gov (United States)

    Della Mea, V; Beltrami, C A

    2000-01-01

    The last five years experience has definitely demonstrated the possible applications of the Internet for telepathology. They may be listed as follows: (a) teleconsultation via multimedia e-mail; (b) teleconsultation via web-based tools; (c) distant education by means of World Wide Web; (d) virtual microscope management through Web and Java interfaces; (e) real-time consultations through Internet-based videoconferencing. Such applications have led to the recognition of some important limits of the Internet, when dealing with telemedicine: (i) no guarantees on the quality of service (QoS); (ii) inadequate security and privacy; (iii) for some countries, low bandwidth and thus low responsiveness for real-time applications. Currently, there are several innovations in the world of the Internet. Different initiatives have been aimed at an amelioration of the Internet protocols, in order to have quality of service, multimedia support, security and other advanced services, together with greater bandwidth. The forthcoming Internet improvements, although induced by electronic commerce, video on demand, and other commercial needs, are of real interest also for telemedicine, because they solve the limits currently slowing down the use of Internet. When such new services will be available, telepathology applications may switch from research to daily practice in a fast way.

  8. Phonion: Practical Protection of Metadata in Telephony Networks

    Directory of Open Access Journals (Sweden)

    Heuser Stephan

    2017-01-01

    Full Text Available The majority of people across the globe rely on telephony networks as their primary means of communication. As such, many of the most sensitive personal, corporate and government related communications pass through these systems every day. Unsurprisingly, such connections are subject to a wide range of attacks. Of increasing concern is the use of metadata contained in Call Detail Records (CDRs, which contain source, destination, start time and duration of a call. This information is potentially dangerous as the very act of two parties communicating can reveal significant details about their relationship and put them in the focus of targeted observation or surveillance, which is highly critical especially for journalists and activists. To address this problem, we develop the Phonion architecture to frustrate such attacks by separating call setup functions from call delivery. Specifically, Phonion allows users to preemptively establish call circuits across multiple providers and technologies before dialing into the circuit and does not require constant Internet connectivity. Since no single carrier can determine the ultimate destination of the call, it provides unlinkability for its users and helps them to avoid passive surveillance. We define and discuss a range of adversary classes and analyze why current obfuscation technologies fail to protect users against such metadata attacks. In our extensive evaluation we further analyze advanced anonymity technologies (e.g., VoIP over Tor, which do not preserve our functional requirements for high voice quality in the absence of constant broadband Internet connectivity and compatibility with landline and feature phones. Phonion is the first practical system to provide guarantees of unlinkable communication against a range of practical adversaries in telephony systems.

  14. Comparison of H.323 and SIP for IP telephony signaling

    Science.gov (United States)

    Dalgic, Ismail; Fang, Hanlin

    1999-11-01

    Two standards currently compete for the dominance of IP telephony signaling: the H.323 protocol suite by ITU-T, and the Session Initiation Protocol (SIP) by IETF. Both of these signaling protocols provide mechanisms for call establishment and teardown, call control and supplementary services, and capability exchange. We investigate and compare these two protocols in terms of Functionality, Quality of Service (QoS), Scalability, Flexibility, Interoperability, and Ease of Implementation. For fairness of comparison, we consider similar scenarios for both protocols. In particular, we focus on scenarios that involve a gatekeeper for H.323, and a Proxy/Redirect server for SIP. The reason is that medium-to-large IP Telephony systems are not manageable without a gatekeeper or proxy server. We consider all three versions of H.323. In terms of functionality and services that can be supported, H.323 version 2 and SIP are very similar. However, supplementary services in H.323 are more rigorously defined, and therefore fewer interoperability issues are expected among its implementations. Furthermore, H.323 has taken more steps to ensure compatibility among its different versions, and to interoperate with PSTN. The two protocols are comparable in their QoS support [similar call setup delays, no support for resource reservation or class of service (CoS) setting], but H.323 version 3 will allow signaling of the requested CoS. SIP's primary advantages are (1) flexibility to add new features, and (2) relative ease of implementation and debugging. Finally, we note that H.323 and SIP are improving themselves by learning from each other, and the differences between them are diminishing with each new version.

    2018-01-01

    Full Text Available Introduction: The article is devoted to the use of various means and technologies of the Internet on technology lessons. As the authors of the article show, recently a lot of sites, applicable for joint work, so-called Web 2.0 tools have been developed and put into operation. Many of them can facilitate the work of teachers, make the material more visible, more quickly monitor the performance of homework, etc. The authors are sure that such services as google-tables and google-presentations can reduce the organizational time in the lesson, which is so expensive for practical classes, will make it possible to disassemble more new material, increase the efficiency and speed of the practical work.Materials and methods: The article examines different methods of organizing a lesson using Internet services: when studying a new topic, when working on a project, with differentiated work in a lesson, etc.The results of the research: The article describes the Internet services that the technology teachers can use in their professional activities: a graphical service for creating the layout and interior of the house Planoplan, services that allow you to create schemes for embroidery and share the already created schemes with other embroiderers (igolki.net, x.fanreal.ru, crosti.ru and othersDiscussion and conclusion: The article discusses the complexity of the use of virtual services in the study of the subject of Technology, namely the fact that the student needs to learn the manual operations used for centuries that were not worked out on one generation of students with virtually no changes in the methodology. In addition, there are practically no services developed specifically for the method of teaching the subject of Technology. Internet technologies have firmly taken their positions in the life of modern society. Teachers should use all the tools that can attract the attention of a new generation to teach them their subject.

  12. Telephony Over IP: A QoS Measurement-Based End to End Control Algorithm

    Directory of Open Access Journals (Sweden)

    Luigi Alcuri

    2004-12-01

    Full Text Available This paper presents a method for admitting voice calls in Telephony over IP (ToIP scenarios. This method, called QoS-Weighted CAC, aims to guarantee Quality of Service to telephony applications. We use a measurement-based call admission control algorithm, which detects network congested links through a feedback on overall link utilization. This feedback is based on the measures of packet delivery latencies related to voice over IP connections at the edges of the transport network. In this way we introduce a close loop control method, which is able to auto-adapt the quality margin on the basis of network load and specific service level requirements. Moreover we evaluate the difference in performance achieved by different Queue management configurations to guarantee Quality of Service to telephony applications, in which our goal was to evaluate the weight of edge router queue configuration in complex and real-like telephony over IP scenario. We want to compare many well-know queue scheduling algorithms, such as SFQ, WRR, RR, WIRR, and Priority. This comparison aims to locate queue schedulers in a more general control scheme context where different elements such as DiffServ marking and Admission control algorithms contribute to the overall Quality of Service required by real-time voice conversations. By means of software simulations we want to compare this solution with other call admission methods already described in scientific literature in order to locate this proposed method in a more general control scheme context. On the basis of the results we try to evidence the possible advantages of this QoS-Weighted solution in comparison with other similar CAC solutions ( in particular Measured Sum, Bandwidth Equivalent with Hoeffding Bounds, and Simple Measure CAC, on the planes of complexity, stability, management, tune-ability to service level requirements, and compatibility with actual network implementation.

    2016-10-01

    To ensure that end-users and consumers have access to comprehensive, comparable and user-friendly information regarding the Internet access service quality, it is necessary to implement and regularly renew a set of legislative regulatory acts and to provide monitoring of the quality of Internet access services regarding the current European Regulatory Framework. The actual situation regarding the quality of service monitoring solutions in different European countries depends on national regulatory initiatives and public awareness. The service monitoring solutions are implemented using different measurement methodologies and tools. The paper investigates the practical implementations for developing a harmonising approach to quality monitoring in order to obtain objective information on the quality of Internet access services on mobile networks.

  16. Troublesome telephony: how users and non-users shaped the development of early British exchange telephony

    Directory of Open Access Journals (Sweden)

    Dr Michael Kay

    2015-05-01

    Full Text Available When exchange telephony was first marketed to the British public by the early telephone companies in the late nineteenth century it was as an intuitive technology requiring no specialist knowledge or training. This has gone unquestioned in subsequent telephone historiography but, as this article demonstrates, telephone instruments and systems were not always unproblematic or easy to use. Whilst other scholars have discussed important factors in the development and uptake of telephony, such as business economics and intellectual property, this article focuses on usage, and argues that difficulties in using telephone instruments and systems also influenced key changes in the operations of early British exchange systems. To understand these responses and developments it is necessary to look at the opinions and complaints of both users and non-users of telephone exchange systems. In investigating non-users as well as users, this article is influenced by the work of Sally Wyatt in Oudshoorn and Pinch's (2003 edited volume regarding users and non-users of technologies. Recovering the reactions of such people is possible through extensive use of letters received by the telephone companies or published in the periodical press, and opinions voiced at select committee meetings investigating the state of the country's telephone system. In recovering the difficulties early users and non-users faced when confronted with exchange telephone systems this article emphasises the importance of problematising the historical uptake of new technologies, and highlights how, in the case of early British telephony in particular, these problems can reveal specific facts both about historical telephone use-experience and about how exchange telephony spread around the country.

    Yenyuen, Yee; Yeow, P. H. P.

    The study is the first research in Malaysia that investigates user acceptance of Internet banking service (IBS) based on Unified Theory of Acceptance and Use of Technology model (Venkatesh, Morris, Davis and Davis, 2003). Two hundred and eighty questionnaires were distributed and collected from two major cities, Kuala Lumpur and Melaka. Descriptive statistics was used to analyse the data. The results show that Malaysians have intentions of using IBS (mean rating of close to 4.00). Moreover, Malaysians recognize the benefits of IBS by giving a high mean rating (close to 4.00) to performance expectancy. However, they give relative low mean ratings (close to 3.00) on other indicators of Behavioural Intention to Use IBS such as effort expectancy, social influence, facilitating conditions and perceived credibility. Recommendations were given to promote a safe, efficient and conducive environment for user adoption of Internet banking.

  19. Evaluating Common Privacy Vulnerabilities in Internet Service Providers

    Science.gov (United States)

    Kotzanikolaou, Panayiotis; Maniatis, Sotirios; Nikolouzou, Eugenia; Stathopoulos, Vassilios

    Privacy in electronic communications receives increased attention in both research and industry forums, stemming from both the users' needs and from legal and regulatory requirements in national or international context. Privacy in internet-based communications heavily relies on the level of security of the Internet Service Providers (ISPs), as well as on the security awareness of the end users. This paper discusses the role of the ISP in the privacy of the communications. Based on real security audits performed in national-wide ISPs, we illustrate privacy-specific threats and vulnerabilities that many providers fail to address when implementing their security policies. We subsequently provide and discuss specific security measures that the ISPs can implement, in order to fine-tune their security policies in the context of privacy protection.

  2. Improving Service Management in the Internet of Things

    Science.gov (United States)

    Sammarco, Chiara; Iera, Antonio

    2012-01-01

    In the Internet of Things (IoT) research arena, many efforts are devoted to adapt the existing IP standards to emerging IoT nodes. This is the direction followed by three Internet Engineering Task Force (IETF) Working Groups, which paved the way for research on IP-based constrained networks. Through a simplification of the whole TCP/IP stack, resource constrained nodes become direct interlocutors of application level entities in every point of the network. In this paper we analyze some side effects of this solution, when in the presence of large amounts of data to transmit. In particular, we conduct a performance analysis of the Constrained Application Protocol (CoAP), a widely accepted web transfer protocol for the Internet of Things, and propose a service management enhancement that improves the exploitation of the network and node resources. This is specifically thought for constrained nodes in the abovementioned conditions and proves to be able to significantly improve the node energetic performance when in the presence of large resource representations (hence, large data transmissions).

    2016-05-01

    Full Text Available Employees who abuse Internet privileges have become a major concern among today's employers. Employees misuse Internet at the workplace due to the overcrowded schedule, pressures at work, etc. Internet for private purposes is also used as a release or escape from work, escape from the reality of the workplace or due to poor organizational climate; it can be used as an efficient use of time at work but it can also be excessively used when the employees are not monitored. The survey results show that there is a correlation between Internet addiction and misuse of the Internet in the workplace. Electronic monitoring has a strong impact on the abuse of the Internet. More electronic monitoring will decrease the abuse of the internet services in the workplace and vice versa. Organizational climate, relations in the working organization, the Internet policy and demographic factors do not affect the abuse of Internet services in the workplace.

    Internet of Things (IoT) is the next wave of industry revolution that will initiate many services, such as personal health care and green energy monitoring, which people may subscribe for their convenience. Recommending IoT services to the users based on objects they own will become very crucial for the success of IoT. In this work, we introduce the concept of service recommender systems in IoT by a formal model. As a first attempt in this direction, we have proposed a hyper-graph model for IoT recommender system in which each hyper-edge connects users, objects, and services. Next, we studied the usefulness of traditional recommendation schemes and their hybrid approaches on IoT service recommendation (IoTSRS) based on existing well known metrics. The preliminary results show that existing approaches perform reasonably well but further extension is required for IoTSRS. Several challenges were discussed to point out the direction of future development in IoTSR.

    Full Text Available Telecommunication networks have long ago entered the Critical Infrastructure domain. Apart from the public telephony network, there is a parallel private telephony network, consisting of Private Branch Exchanges (PBXs that serve the communication needs of private or public entities. Their penetration in the market is substantial. As a result, thousands of PBX installations are present in every country serving many times more users in vital infrastructures (including health, safety, security, economy, energy. Therefore, attacking PBXs can have critical effects that disrupt society and can clearly be used in warlike situations. PBXs are an integral part of the critical infrastructure, along with the public telephony network. The contribution of this work focuses on the theoretical and practical capabilities of a malware able to target PBXs. Such an occurrence would have devastating effects on the communication confidentiality, integrity and availability.

This paper proposes that the suitable alternative solution of grid power is the stand-alone PV/wind hybrid energy system with diesel generator as a backup for cellular mobile telephony base station site in isolated areas. It is expected that the newly developed and installed system would provide very good opportunities for mobile telephony base station in near future. In addition, protecting the environment and combating climate change are two of the most pressing challenges facing humankind. As energy prices soar, network operators are increasingly scrutinizing their environmental and social responsibilities. This system will be more cost effective and environmental friendly over the conventional diesel generator. Approximately 70-80% fuel cost over conventional diesel generator and the emission of CO 2 and other harmful gasses in environments were reduced. (author)

    CERN Document Server

    Lewcio, Błażej

    2014-01-01

    This book shows how networking research and quality engineering can be combined to successfully manage the transmission quality when speech and video telephony is delivered in heterogeneous wireless networks. Nomadic use of services requires intelligent management of ongoing transmission, and to make the best of available resources many fundamental trade-offs must be considered. Network coverage versus throughput and reliability of a connection is one key aspect, efficiency versus robustness of signal compression is another. However, to successfully manage services, user-perceived Quality of Experience (QoE) in heterogeneous networks must be known, and the perception of quality changes must be understood.  These issues are addressed in this book, in particular focusing on the perception of quality changes due to switching between diverse networks, speech and video codecs, and encoding bit rates during active calls.

    As the "Internet of Things" is expected to grow rapidly in the following years, the need to develop and deploy efficient and scalable Discovery Services in this context is very important for its success. Thus, the ability to evaluate and compare the performance of different Discovery Services architectures is vital if we want to allege that a given design is better at meeting requirements of a specific application. The purpose of this chapter is to provide a paradigm for the evaluation of different Discovery Services for the Internet of Things in terms of efficiency, scalability and performance through the use of simulations. The methodology presented uses the application of Discovery Services to a supply chain with the Service Lookup Service Discovery Service using OMNeT++, an open source network simulation suite. Then, we delve into the simulation design and the details of our findings.

  3. Risks of carcinogenesis from electromagnetic radiation of mobile telephony devices.

    Science.gov (United States)

    Yakymenko, I; Sidorik, E

    2010-07-01

    Intensive implementation of mobile telephony technology in everyday human life during last two decades has given a possibility for epidemiological estimation of long-term effects of chronic exposure of human organism to low-intensive microwave (MW) radiation. Latest epidemiological data reveal a significant increase in risk of development of some types of tumors in chronic (over 10 years) users of mobile phone. It was detected a significant increase in incidence of brain tumors (glioma, acoustic neuroma, meningioma), parotid gland tumor, seminoma in long-term users of mobile phone, especially in cases of ipsilateral use (case-control odds ratios from 1.3 up to 6.1). Two epidemiological studies have indicated a significant increase of cancer incidence in people living close to the mobile telephony base station as compared with the population from distant area. These data raise a question of adequacy of modern safety limits of electromagnetic radiation (EMR) exposure for humans. For today the limits were based solely on the conception of thermal mechanism of biological effects of RF/MW radiation. Meantime the latest experimental data indicate the significant metabolic changes in living cell under the low-intensive (non-thermal) EMR exposure. Among reproducible biological effects of low-intensive MWs are reactive oxygen species overproduction, heat shock proteins expression, DNA damages, apoptosis. The lack of generally accepted mechanism of biological effects of low-intensive non-ionizing radiation doesn't permit to disregard the obvious epidemiological and experimental data of its biological activity. Practical steps must be done for reasonable limitation of excessive EMR exposure, along with the implementation of new safety limits of mobile telephony devices radiation, and new technological decisions, which would take out the source of radiation from human brain.

    In this paper we present a mechanism to provide Quality of Service (QoS) guarantees to different multimedia applications that share link bandwidth in IP-based differential services domain. In this mechanism weights are associated with each and to individual users according to their priorities. In order to evaluate the performance of our scheme we conducted simulations. The test data used portray different multimedia applications i.e. MPEG-2, IP telephony. The simulation results obtained show the effectiveness of our scheme for multimedia applications by allocating link share to each multimedia application and minimising end-to-end transmission delay 9Y bringing them in line with the recommended standard acceptable transmission delay for multimedia applications. This paper also presents extension to our proposed Relative Bandwidth Sharing (RES) scheme for differential services. We have identified and highlighted the role of border routers and core routers in differential services domain. Exploring features of Internet Protocol IPv6 in our architecture. (author)

    The National Institute of Standards and Technology (NIST) is expanding into a new frontier in the delivery of measurement services. The Internet will be employed to provide industry with electronic traceability to national standards. This is a radical departure from the traditional modes of traceability and presents many new challenges. The traditional mail-based calibration service relies on sending artifacts to the user, who then mails them back to NIST for evaluation. The new service will deliver calibration results to the industry customer on-demand, in real-time, at a lower cost. The calibration results can be incorporated rapidly into the production process to ensure the highest quality manufacturing. The service would provide the US radiation processing industry with a direct link to the NIST calibration facilities and its expertise, and provide an interactive feedback process between industrial processing and the national measurement standard. Moreover, an Internet calibration system should contribute to the removal of measurement-related trade barriers

    While Australians are searching the internet for third molar (TM) information, the usefulness of online sources may be questioned due to quality variation. This study explored: (i) internet use, online information-seeking behaviour among TM patients attending public dental services; and (ii) whether patients' TM knowledge scores are associated with the level of internet use and eHealth Literacy Scale (eHEALS) scores. Baseline survey data from the 'Engaging Patients in Decision-Making' study were used. Variables included: sociodemographics, internet access status, online information-seeking behaviour, eHEALS, the Control Preferences Scale (CPS) and TM knowledge. Participants (N = 165) were mainly female (73.8%), aged 19-25 years (42.4%) and had 'secondary school or less' education (58.4%). A majority (N = 79, 52.7%) had sought online dental information which was associated with active decisional control preference (odds ratio = 3.1, P = 0.034) and higher educational attainment (odds ratio = 2.7, P = 0.040). TM knowledge scores were not associated with either the level of internet use (F (2,152) = 2.1, P = 0.094, χ 2 = 0.0310) or the eHEALS scores (r = 0.147, P = 0.335). 'The internet-prepared patient' phenomena exists among public TM patients and was explained by preference for involvement in decision-making. However, internet use was not associated with better TM knowledge. Providing TM patients with internet guidance may be an opportunity to improve TM knowledge. © 2017 Australian Dental Association.

    2003-01-01

    PURPOSE The increasing use of the Internet to obtain genetics information and to order medical services without a prescription, combined with a rise in direct-to-consumer marketing for genetic testing, suggests the potential for the Internet to be used to sell genetic services. METHODS A systematic World Wide Web search was conducted in May 2002 to assess the availability of genetic services sold directly to consumers on the Internet. RESULTS Out of 105 sites that offered genetic services directly, most offered non-health-related services, including parentage confirmation testing (83%), identity testing (56%), and DNA banking (24%); however, health-related genetic tests were offered through 14 sites (13%). The health-related genetic tests available ranged from standard tests, such as hemochromatosis and cystic fibrosis, to more unconventional tests related to nutrition, behavior, and aging. Of these 14 sites, 5 described risks associated with the genetic services and 6 described the availability of counseling. CONCLUSIONS The availability of direct sales of health-related genetic tests creates the potential for inadequate pretest decision making, misunderstanding test results, and access to tests of questionable clinical value.

    Full Text Available The growing popularity of RFID (Radio Frequency Identification systems cannot be overlooked due to their wide range of application areas. However, some RFID applications face security and privacy threats due to the exposure of tags over wider distances. There are security methods but these can lack security and scalability when authenticating RF tags in MORIS (Multi Organizational RFID System. RFID systems operating within a single domain have only security and privacy issues due to the security method on tags, but in a multi-organizational system there are even more security and privacy issues in the system architecture rather than just in the security method on tag side. In this paper, we have designed a broker service to EPC (Electronic Product Code system architecture for secure and confidential data management of the RFID data events. Secure and confidential authentication broker service is an extension to the EPC network architecture for a MORIS. The central authentication broker service ensures to avoid illicit access to the confidential RFID tag\\'s data such as EPC code, whilst managing a large-scale authentication data to ensure secure and deterministic response to the authentic entities of the system.

    The Internet of Things (IoT) makes it possible for us to sense the physical world and locate objects in it using the enabling technologies associated with IoT. Compared with traditional information systems, IoT enabling technologies can help acquire real-time data necessary for managing enterprise business process. An IoT system should have an ability beyond integrating enabling technologies and traditional information systems that are only used to access environmental data. This paper begins with a literature review of IoT-related issues and a discussion of the difference between traditional information service and IoT service. Three principles for IoT service design from the perceptive of service classification, coordination and compatibility are proposed. The paper also proposes a utility model for resource allocation in order to improve IoT service performance, and an application involving a cold chain visibility platform is given to illustrate our research.

    Full Text Available Current trends towards the Future Internet are envisaging the conception of novel services endowed with context-aware and autonomic capabilities to improve end users’ quality of life. The Internet of Things paradigm is expected to contribute towards this ambitious vision by proposing models and mechanisms enabling the creation of networks of “smart things” on a large scale. It is widely recognized that efficient mechanisms for discovering available resources and capabilities are required to realize such vision. The contribution of this work consists in a novel discovery service for the Internet of Things. The proposed solution adopts a peer-to-peer approach for guaranteeing scalability, robustness, and easy maintenance of the overall system. While most existing peer-to-peer discovery services proposed for the IoT support solely exact match queries on a single attribute (i.e., the object identifier, our solution can handle multiattribute and range queries. We defined a layered approach by distinguishing three main aspects: multiattribute indexing, range query support, peer-to-peer routing. We chose to adopt an over-DHT indexing scheme to guarantee ease of design and implementation principles. We report on the implementation of a Proof of Concept in a dangerous goods monitoring scenario, and, finally, we discuss test results for structural properties and query performance evaluation.

    2016-07-01

    Full Text Available The Internet of Things (IoT opens up tremendous opportunities to provide location-based applications. However, despite the services around a user being physically adjacent, common IoT platforms use a centralized structure, like a cloud-computing architecture, which transfers large amounts of data to a central server. This raises problems, such as traffic concentration, long service latency, and high communication cost. In this paper, we propose a physical distance-based asynchronous messaging platform that specializes in processing personalized data and location-based messages. The proposed system disperses traffic using a location-based message-delivery protocol, and has high stability.

    The increase within the energy and effect consumption in Norway, parallel with a small development of new power production has resulted in an increased focus on the end user flexibility. An efficient utilisation of the end user flexibility assumes that the market mechanisms are adapted/developed so that the user has economical incentives for reducing the consumption in periods with energy and effect shortage. Furthermore the technological solutions within the information and communication technology (ICT) open new possibilities for acquiring energy and effect reducing potentials at the end users. The Internet is an universal communication channel which opens new possibilities for communication between the power market and the end users. The unique properties of the internet particularly the easy access and low costs for upgrading and maintenance, makes a considerable potential for the use of new products and services which will increase the flexibility in the use of energy and effect. The report presents a survey of existing products and services which are offered on the Internet in the power sector. The report emphasises particularly on a comparison of these solutions regarding purpose, functionality, user friendliness and limitations of these products. The appendix includes a glossary of works and expressions which is related to the ICT.

    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.

  5. Removing Ambiguities of IP Telephony Traffic Using Protocol Scrubbers

    Bazara I. A. Barry

    2012-10-01

    Full Text Available Network intrusion detection systems (NIDSs face the serious challenge of attacks such as insertion and evasion attacks that are caused by ambiguous network traffic. Such ambiguity comes as a result of the nature of network traffic which includes protocol implementation variations and errors alongside legitimate network traffic. Moreover, attackers can intentionally introduce further ambiguities in the traffic. Consequently, NIDSs need to be aware of these ambiguities when detection is performed and make sure to differentiate between true attacks and protocol implementation variations or errors; otherwise, detection accuracy can be affected negatively. In this paper we present the design and implementation of tools that are called protocol scrubbers whose main functionality is to remove ambiguities from network traffic before it is presented to the NIDS. The proposed protocol scrubbers are designed for session initiation and data transfer protocols in IP telephony systems. They guarantee that the traffic presented to NIDSs is unambiguous by eliminating ambiguous behaviors of protocols using well-designed protocol state machines, and walking through packet headers of protocols to make sure packets will be interpreted in the desired way by the NIDS. The experimental results shown in this paper demonstrate the good quality and applicability of the introduced scrubbers.

    Various types of monitoring mechanism allow us to detect and monitor behavior of attackers in VoIP networks. Analysis of detected malicious traffic is crucial for further investigation and hardening the network. This analysis is typically based on statistical methods and the article brings a solution based on neural network. The proposed algorithm is used as a classifier of attacks in a distributed monitoring network of independent honeypot probes. Information about attacks on these honeypots is collected on a centralized server and then classified. This classification is based on different mechanisms. One of them is based on the multilayer perceptron neural network. The article describes inner structure of used neural network and also information about implementation of this network. The learning set for this neural network is based on real attack data collected from IP telephony honeypot called Dionaea. We prepare the learning set from real attack data after collecting, cleaning and aggregation of this information. After proper learning is the neural network capable to classify 6 types of most commonly used VoIP attacks. Using neural network classifier brings more accurate attack classification in a distributed system of honeypots. With this approach is possible to detect malicious behavior in a different part of networks, which are logically or geographically divided and use the information from one network to harden security in other networks. Centralized server for distributed set of nodes serves not only as a collector and classifier of attack data, but also as a mechanism for generating a precaution steps against attacks.

  7. Mobile telephony and the precautionary principle - a phoney debate?

    Anderson, V.

    2001-01-01

    This paper explores potential adverse consequences of applying the precautionary principle (PP) to low-level radiofrequency (RF) transmissions from mobile phones and base stations. An oft-cited criticism of the PP is that it is poorly and inconsistently defined. In its best and most inclusive form, as defined in a recent communication from the European Commission, the PP includes elements of proportionality, non-discrimination, consistency, cost/benefit analysis and ongoing scientific review. In its worst form the PP can introduce arbitrary and onerous regulatory measures without regard to new community risks and costs that may be generated, e.g.: 1. Denying or delaying public access to the social, economic and public safety benefits of mobile telephony; 2. Redirection of limited community resources away from more important public safety issues; 3. Protracted legal argument (and costs) over the vague definitions inherent in the PP; 4. Undermining of the integrity of the scientific method in determining the true level of any health risk from direct exposure to low level EME; 5. Inappropriate occupational and public risk behaviors based on an exaggerated concern of EME as implied by the PP. There is little published data to quantify these risks, though a strong prima facie case exists for a cautious approach to the PP. A considered decision on the PP that protects the public interest will require quantitative analysis of the risks generated by the PP described above.

  8. 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.

    In the Internet of Things a code resolution service provides a discovery mechanism for a requester to obtain the information resources associated with a particular product code immediately. In large scale application scenarios a code resolution service faces some serious issues involving heterogeneity, big data and data ownership. A code resolution service network is required to address these issues. Firstly, a list of requirements for the network architecture and code resolution services is proposed. Secondly, in order to eliminate code resolution conflicts and code resolution overloads, a code structure is presented to create a uniform namespace for code resolution records. Thirdly, we propose a loosely coupled distributed network consisting of heterogeneous, independent; collaborating code resolution services and a SkipNet based code resolution service named SkipNet-OCRS, which not only inherits DHT’s advantages, but also supports administrative control and autonomy. For the external behaviors of SkipNet-OCRS, a novel external behavior mode named QRRA mode is proposed to enhance security and reduce requester complexity. For the internal behaviors of SkipNet-OCRS, an improved query algorithm is proposed to increase query efficiency. It is analyzed that integrating SkipNet-OCRS into our resolution service network can meet our proposed requirements. Finally, simulation experiments verify the excellent performance of SkipNet-OCRS.

  12. Time-Aware Service Ranking Prediction in the Internet of Things Environment.

    2017-04-27

    With the rapid development of the Internet of things (IoT), building IoT systems with high quality of service (QoS) has become an urgent requirement in both academia and industry. During the procedures of building IoT systems, QoS-aware service selection is an important concern, which requires the ranking of a set of functionally similar services according to their QoS values. In reality, however, it is quite expensive and even impractical to evaluate all geographically-dispersed IoT services at a single client to obtain such a ranking. Nevertheless, distributed measurement and ranking aggregation have to deal with the high dynamics of QoS values and the inconsistency of partial rankings. To address these challenges, we propose a time-aware service ranking prediction approach named TSRPred for obtaining the global ranking from the collection of partial rankings. Specifically, a pairwise comparison model is constructed to describe the relationships between different services, where the partial rankings are obtained by time series forecasting on QoS values. The comparisons of IoT services are formulated by random walks, and thus, the global ranking can be obtained by sorting the steady-state probabilities of the underlying Markov chain. Finally, the efficacy of TSRPred is validated by simulation experiments based on large-scale real-world datasets.

    Full Text Available With the rapid development of the Internet of things (IoT, building IoT systems with high quality of service (QoS has become an urgent requirement in both academia and industry. During the procedures of building IoT systems, QoS-aware service selection is an important concern, which requires the ranking of a set of functionally similar services according to their QoS values. In reality, however, it is quite expensive and even impractical to evaluate all geographically-dispersed IoT services at a single client to obtain such a ranking. Nevertheless, distributed measurement and ranking aggregation have to deal with the high dynamics of QoS values and the inconsistency of partial rankings. To address these challenges, we propose a time-aware service ranking prediction approach named TSRPred for obtaining the global ranking from the collection of partial rankings. Specifically, a pairwise comparison model is constructed to describe the relationships between different services, where the partial rankings are obtained by time series forecasting on QoS values. The comparisons of IoT services are formulated by random walks, and thus, the global ranking can be obtained by sorting the steady-state probabilities of the underlying Markov chain.

    Services based on the Internet of Things (IoT) technologies have emerged in various business environments. To enhance health service quality and maximize benefits, this study applied an IoT technology based on NFC and iBeacon as an omni-channel service for patient care in hospitals. Application of the IoT technology based on NFC and iBeacon was conducted in a general hospital during August 2015 through June 2016, and the development and evaluation results were aligned to an action research framework. The five phases in the action research included diagnosing, planning action, taking action, evaluating action, and specifying learning phases. During the first two phases, problems of functional operations in a hospital were diagnosed and eight service models were designed by using iBeacon and NFC to solve the problems. Service models were applied to the hospital by installing beacons, wearable beacons, beacon scanners, and NFC tags during the third phase. During the fourth and fifth phases, the roles and benefits of stakeholders participating in the service models were evaluated, and issues and knowledge of the whole application process were derived and summarized from technological, economic, social and legal perspectives, respectively. From an action research perspective, IoT-based healthcare services were developed and verified. IoT-based services enable the hospital to acquire lifelog data for precision medicine and ultimately be able to go one step closer to precision medical care. The derived service models could provide patients more enhanced healthcare services and improve the work efficiency and effectiveness of the hospital.

    To identify users' reasons to look for physician consultation on the internet instead of visiting a physician and to explore their general characteristics, motivation, and satisfaction with internet medical consultation service 'Your Questions.' Users of a free internet medical consultation service 'Your Questions' (www.plivazdravlje.hr) were invited to participate in a web-based survey designed to explore their general characteristics (age, sex, etc), reasons for using the service, the nature of their health problem or question, and their satisfaction with the service. Respondents were divided into two groups: users who consulted an internet physician only (Group I) and users who used internet consulting before or after visiting a physician (Group II). The response rate was 38% (1036/2747), with 79% female respondents. A fifth of the respondents (21%) consulted an internet physician only (Group I). Multivariate analysis revealed that the respondents in Group I were younger (median 24 vs 28 years in Group II), more interested into questions about pregnancy (odds ratio [OR], 1.984; 95% confidence interval [CI], 1.203-3.272), more often embarrassed to talk to a physician in person (OR, 1.828; 95% CI, 1.119-2.989), and more motivated to protect their privacy (OR, 1.727; 95% CI, 1.252-2.380). They also had greater satisfaction with the service (77% vs 60%, Pinternet-based medical consultation services were younger age, need for privacy protection, avoidance of embarrassment at the physician's office, and having a question related to pregnancy. This reveals the internet medical consultation service as a useful health promotion supplement that is particularly applicable for the population of young adults.

    The aim of our study was to investigate Internet and eHealth usage, with respect to eHealth literacy, by cancer patients and their relatives. Using a standardized questionnaire we asked patients who attended lectures on complementary medicine in 2016. We received 142 questionnaires. The frequency of general Internet usage was directly associated with younger age and better Internet connection. Younger participants were not only more confident in allocating health-related Internet information into reliable or unreliable facts, but also more confident and capable of gaining medical knowledge through eHealth services. A regular use of eHealth services facilitated the decision-making process. Reading ability was associated with a better understanding regarding eHealth offers. In a modern health care system, emphasis should be on skills contributing to eHealth literacy among patients to improve their ability to profit from eHealth offers and improve health care.

    Huang, Chih-Yuan; Wu, Cheng-Hung

    2016-01-01

    The Internet of Things (IoT) is an infrastructure that interconnects uniquely-identifiable devices using the Internet. By interconnecting everyday appliances, various monitoring, and physical mashup applications can be constructed to improve human’s daily life. In general, IoT devices provide two main capabilities: sensing and tasking capabilities. While the sensing capability is similar to the World-Wide Sensor Web, this research focuses on the tasking capability. However, currently, IoT devices created by different manufacturers follow different proprietary protocols and are locked in many closed ecosystems. This heterogeneity issue impedes the interconnection between IoT devices and damages the potential of the IoT. To address this issue, this research aims at proposing an interoperable solution called tasking capability description that allows users to control different IoT devices using a uniform web service interface. This paper demonstrates the contribution of the proposed solution by interconnecting different IoT devices for different applications. In addition, the proposed solution is integrated with the OGC SensorThings API standard, which is a Web service standard defined for the IoT sensing capability. Consequently, the Extended SensorThings API can realize both IoT sensing and tasking capabilities in an integrated and interoperable manner. PMID:27589759

    Full Text Available The development of the Internet of Things (IoT is closely related to a considerable increase in the number and variety of devices connected to the Internet. Sensors have become a regular component of our environment, as well as smart phones and other devices that continuously collect data about our lives even without our intervention. With such connected devices, a broad range of applications has been developed and deployed, including those dealing with massive volumes of data. In this paper, we introduce a Distributed Data Service (DDS to collect and process data for IoT environments. One central goal of this DDS is to enable multiple and distinct IoT middleware systems to share common data services from a loosely-coupled provider. In this context, we propose a new specification of functionalities for a DDS and the conception of the corresponding techniques for collecting, filtering and storing data conveniently and efficiently in this environment. Another contribution is a data aggregation component that is proposed to support efficient real-time data querying. To validate its data collecting and querying functionalities and performance, the proposed DDS is evaluated in two case studies regarding a simulated smart home system, the first case devoted to evaluating data collection and aggregation when the DDS is interacting with the UIoT middleware, and the second aimed at comparing the DDS data collection with this same functionality implemented within the Kaa middleware.

    2001-12-01

    Universities across the nation are transforming their teaching and research efforts through increased use of a rapidly expanding menu of environmental data. With funding from the Division of Atmospheric Sciences (ATM ) of the National Science Foundation (NSF), the Unidata Program is playing a central role in this transformation by enabling universities to employ innovative computing and networking technologies to acquire such data sets in real-time and use them routinely in their classrooms and research labs. Working with the Unidata Program Center (UPC), the Unidata community, comprising over 140 departments, has built a national Internet Data Distribution (IDD ) system. The IDD allows users to "subscribe" to certain sets of data products; IDD servers then deliver the requested data to their local servers as soon as they are available from the source. With the initial national implementation in 1994, the IDD may have been the original example of Internet "push" technology. It now provides the reliability, flexibility, and efficiency required by participating institutions. As the underlying Internet technology evolves, we anticipate dramatic increases in the volume of data delivered. We plan to augment the system to better serve disciplines outside the atmospheric sciences and to incorporate anticipated new networking technologies to minimize the impact of the IDD on the underlying network. Unidata has recently undertaken a new initiative called THREDDS (THematic Real-time Environmental Distributed Data Services) under a grant from the NSF Division of Undergraduate Education NSDL (National Science, Math, Engineering, Technology Education Digital Library). The goal of THREDDs is to make it possible for students, educators and researchers to publish, contribute, find, and interact with data relating to the Earth system in a convenient, effective, and integrated fashion. Just as the World Wide Web and digital-library technologies have simplified the process of

    Full Text Available Introduction: Internet-based guided self-help and face-to-face CBT have shown to be effective in the treatment of depression, but both approaches might not be an available treatment option for all patients. A treatment which blends internet-based guided self-help with video-based psychotherapy might reduce potential disadvantages of both approaches, while maintaining major advantages such as being location-independent. Additionally, it could provide a stronger focus on patient empowerment and lower resource use compared to traditional face-to-face treatment. Aim: The aim of this study is to evaluate patient's experiences with blended internet- and video-based CBT (blended iCBT treatment and to derive suggestions for the improvement of such services. Methods: Semi-structured interviews were conducted with 15 participants of the blended iCBT treatment as part of the European MasterMind trial. Participants included adults suffering from Major Depressive Disorder. The interview guide assessed patient's experiences regarding the four treatment components program, 1. face-to-face diagnostic interviews, 2. video-based synchronous therapy sessions (VTS, 3. online self-help treatment modules (OTM as well as 4. behaviour diaries and symptom monitoring. Interviews were analyzed using the framework method and outcomes regarding connections within and between participants and categories were generated by counting the statements within relevant themes. Results: Overall, patients indicated to have been satisfied with all components of the treatment, highlighting the option to independently work from home in their own pace. While the OTMs allowed for a deeper reflection of the content, the VTS with the therapist were mentioned to provide the personal character of the service. The working alliance with the therapist was experienced as fostering the individual fit of the treatment. Patients reported a high self-perceived treatment effectiveness. Negative effects

    Full Text Available In the last years, we have witnessed the introduction of the Internet of Things (IoT as an integral part of the Internet with billions of interconnected and addressable everyday objects. On one hand, these objects generate a massive volume of data that can be exploited to gain useful insights into our day-to-day needs. On the other hand, context-aware recommender systems (CARSs are intelligent systems that assist users to make service consumption choices that satisfy their preferences based on their contextual situations. However, one of the key challenges facing the development and deployment of CARSs is the lack of functionality for providing dynamic and reliable context information required by the recommendation decision process. Thus, data obtained from IoT objects and other sources can be exploited to build CARSs that satisfy users’ preferences, improve quality of experience, and boost recommendation accuracy. This article describes various components of a conceptual IoT-based framework for context-aware personalized recommendations. The framework addresses the weakness whereby CARSs rely on static and limited contexts from user’s mobile phone by providing additional components for reliable and dynamic context information, using IoT context sources. The core of the framework consists of a context classification and reasoning management and a dynamic user profile model, incorporating trust to improve the accuracy of context-aware personalized recommendations. Experimental evaluations show that incorporating context and trust into personalized recommendation process can improve accuracy.

    Full Text Available The Internet of Things (IoT has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT term.

    Concerns about security on Internet of Things (IoT) cover data privacy and integrity, access control, and availability. IoT abuse in distributed denial of service attacks is a major issue, as typical IoT devices' limited computing, communications, and power resources are prioritized in implementing functionality rather than security features. Incidents involving attacks have been reported, but without clear characterization and evaluation of threats and impacts. The main purpose of this work is to methodically assess the possible impacts of a specific class-amplified reflection distributed denial of service attacks (AR-DDoS)-against IoT. The novel approach used to empirically examine the threat represented by running the attack over a controlled environment, with IoT devices, considered the perspective of an attacker. The methodology used in tests includes that perspective, and actively prospects vulnerabilities in computer systems. This methodology defines standardized procedures for tool-independent vulnerability assessment based on strategy, and the decision flows during execution of penetration tests (pentests). After validation in different scenarios, the methodology was applied in amplified reflection distributed denial of service (AR-DDoS) attack threat assessment. Results show that, according to attack intensity, AR-DDoS saturates reflector infrastructure. Therefore, concerns about AR-DDoS are founded, but expected impact on abused IoT infrastructure and devices will be possibly as hard as on final victims.

    In 1998 the Swedish noncommercial public health service Infomedica opened an Ask the Doctor service on its Internet portal. At no charge, anyone with Internet access can use this service to ask questions about personal health-related and disease-related matters. To study why individuals choose to consult previously-unknown doctors on the Internet. Between November 1, 2001, and January 31, 2002 a Web survey of the 3622 Ask the Doctor service users, 1036 men (29%) and 2586 (71%) women, was conducted. We excluded 186 queries from users. The results are based on quantitative and qualitative analysis of the answers to the question "Why did you choose to ask a question at Infomedica's 'Ask the Doctor' service?" 1223 surveys were completed (response rate 36 %). Of the participants in the survey 322 (26%) were male and 901 (74%) female. As major reasons for choosing to consult previously-unknown doctors on the Internet participants indicated: convenience (52%), anonymity (36%), "doctors too busy" (21%), difficult to find time to visit a doctor (16%), difficulty to get an appointment (13%), feeling uncomfortable when seeing a doctor (9%), and not being able to afford a doctors' visit (3%). Further motives elicited through a qualitative analysis of free-text answers were: seeking a second opinion, discontent with previous doctors and a wish for a primary evaluation of a medical problem, asking embarrassing or sensitive questions, seeking information on behalf of relatives, preferring written communication, and (from responses by expatriates, travelers, and others) living far away from regular health care. We found that that an Internet based Ask the Doctor service is primarily consulted because it is convenient, but it may also be of value for individuals with needs that regular health care services have not been able to meet.

    International health organizations and officials are bracing for a pandemic. Although the 2003 severe acute respiratory syndrome (SARS) outbreak in Toronto did not reach such a level, it created a unique opportunity to identify the optimal use of the Internet to promote communication with the public and to preserve health services during an epidemic. The aim of the study was to explore patients' attitudes regarding the health services that might be provided through the Internet to supplement those traditionally available in the event of a future mass emergency situation. We conducted "mask-to-mask" surveys of patients at three major teaching hospitals in Toronto during the second outbreak of SARS. Patients were surveyed at the hospital entrances and selected clinics. Descriptive statistics and logistic regression models were used for the analysis. In total, 1019 of 1130 patients responded to the survey (90% overall response rate). With respect to Internet use, 70% (711/1019) used the Internet by themselves and 57% (578/1019) with the help of a friend or family member. Of the Internet users, 68% (485/711) had already searched the World Wide Web for health information, and 75% (533/711) were interested in communicating with health professionals using the Internet as part of their ongoing care. Internet users expressed interest in using the Web for the following reasons: to learn about their health condition through patient education materials (84%), to obtain information about the status of their clinic appointments (83%), to send feedback to the hospital about how to improve its services (77%), to access screening tools to help determine if they were potentially affected by the infectious agent responsible for the outbreak (77%), to renew prescriptions (75%), to consult with their health professional about nonurgent matters (75%), and to access laboratory test results (75%). Regression results showed that younger age, higher education, and English as a first

    The goal of this investigation was to estimate the 1999 energy consumption of set-top boxes and telephony products in the U.S. residential sector. Results of this study will be used to identify new energy conservation opportunities and to align programs with those opportunities. We conducted a bottom-up analysis for set-top boxes and telephony products using our own power measurements and stock and usage estimates from secondary sources. The most common set-top boxes in U.S. homes in 1999 were analog cable boxes, digital cable boxes, wireless receivers, and game consoles. According to these measurements, analog cable boxes and wireless receivers draw between 10 and 15 watts, while digital cable boxes draw between 20 and 25 watts in both the Active and Standby modes. Video games used less than 2 watts in Standby mode, and about 8 watts when Active. We estimate that set-top boxes accounted for 0.7% of residential electricity use in 1999. Our investigation of telephony products included answering machines, cordless phones, cordless phone answering machine combination units, and mobile phone chargers. Answering machines, cordless phones, and combination units use between 2 and 3 watts in both the Active and Standby modes. Mobile phone chargers use about 1 watt in standby. We estimate that these telephony products account for 0.5% of U.S. residential electricity consumption. Together, set-tops and telephony constituted 1.2% of U.S. residential electricity consumption in 1999. Standby power use accounted for about 60% of this energy use. The combined total energy use of the products investigated for this study and those researched previously for this series of reports account for about 6.6% of residential electricity use in the U.S

    The Connexion by BoeingSM (CbB) global network will provide broadband information services to aircraft passengers and crews. Through this Ku-band (14 GHz (uplink) and 11/12 GHz (downlink)) satellite-based system, aircraft passengers and crew will no longer be limited to pre-packaged services, but instead will be able to access the full range of broadband services from their seats using their laptop, PDA or the on-board IFE console.The kind of services offered to passengers are based on the internet/intranet access via their own laptops and PDA (using Ethernet wired cable, or wireless 802.11b access), while those offered to the crew can range between various crew application (such as weather updates and travel information) and aircraft health monitoring.The CbB system is divided into four basic layers of infrastructure:(1) an airborne segment, i.e. the Aircraft Earth Station (AES) consisting of proprietary high gain antenna, transceivers and other on-board subsystems providing a nominal return link data rate of 1 Mbps and a forward link data rates up to 20 Mbps;(2) a space segment consisting of leased satellite transponders on existing in-orbit Geostationary satellites;(3) a ground segment consisting of one or more leased satellite land earth stations (LESs) and redundant interconnection facilities; and;(4) a network operations centre (NOC) segment.During 2003, trials with Lufthansa (DLH) and British Airways (BA) have proved very successful. This has resulted in the recent signing of an agreement with Lufthansa which calls for the Connexion by BoeingSM service to be installed on Lufthansa's fleet of approximately 80 long-haul aircraft, including Boeing 747-400 and Airbus A330 and A340 aircraft, beginning in early 2004. BA is expected to follow soon. In addition to the successful recent service demonstrations, both Japan Airlines (JAL) and Scandinavian Airlines System (SAS) have announced their intent to install the revolutionary service on their long-range aircraft.

    2015-01-01

    Previous studies on problematic Internet use have focused almost exclusively on the fact that presence of negative functioning, such as social anxiety, depressive symptoms, or loneliness, represents a risk factor for unhealthy use of the web. For this reason the aim of the present study was to investigate the association between psychological well-being dimensions and problematic use of Internet communicative services. In the current study 495 undergraduate students were recruited. The Italian adaptations of the Psychological Well-being Scales and the Generalized Problematic Internet Use Scale 2 (GPIUS2) were used to assess psychological well-being dimensions and generalized problematic Internet use, respectively. Psychological well-being dimensions explained a significant portion of variance for the GPIUS2 total score levels, after controlling for sex, age, and occupational status. The levels of Autonomy, Environmental Mastery, and Positive Relations with Others acted as significant negative predictors of the tendency to use the web for regulating negative feelings, compulsive use of the web, and the negative outcomes that can arise as a result. The overall findings of the present study provide preliminary evidence that low psychological well-being is associated with problematic use of Internet communicative services.

  17. Dynamic Spectrum Access for Internet of Things Service in Cognitive Radio-Enabled LPWANs.

    2017-12-05

    In this paper, we focus on a dynamic spectrum access strategy for Internet of Things (IoT) applications in two types of radio systems: cellular networks and cognitive radio-enabled low power wide area networks (CR-LPWANs). The spectrum channel contention between the licensed cellular networks and the unlicensed CR-LPWANs, which work with them, only takes place within the cellular radio spectrum range. Our aim is to maximize the spectrum capacity for the unlicensed users while ensuring that it never interferes with the licensed network. Therefore, in this paper we propose a dynamic spectrum access strategy for CR-LPWANs operating in both licensed and unlicensed bands. The simulation and the numerical analysis by using a matrix geometric approach for the strategy are presented. Finally, we obtain the blocking probability of the licensed users, the mean dwell time of the unlicensed user, and the total carried traffic and combined service quality for the licensed and unlicensed users. The results show that the proposed strategy can maximize the spectrum capacity for the unlicensed users using IoT applications as well as keep the service quality of the licensed users independent of them.

    This workshop was convened to explore what is currently being done in the area of data dissemination via the Internet and to examine ways that future activities in this area within the U.S. nuclear data programs can be better coordinated. Overview talks on the current status, from both the national and international perspectives, were provided. Following these, there were presentations on specific activities in the area of Internet data dissemination which are taking place at seven different institutions. Institutions represented at this meeting were asked to provide written summaries of their programs before the meeting. The talks included actual demonstrations of the electronic methodologies which are under development at these laboratories, and they highlighted the richness and creativity of these programs. This information proved to be very useful in the ensuing general discussions. The main issues that were addressed at this meeting were: (i) how to adapt to rapid evolution of data management and dissemination technologies, (ii) how to provide outside users with some sense of unity in the U.S. nuclear data program and to develop consistent, user-friendly ways to access data without discouraging individual initiatives and the richness which comes from diversity, (iii) how to maintain quality control over the information and services provided, (iv) how to progress in a era of very restrictive budgets, (v) how to effectively merge the nuclear structure and nuclear reaction data dissemination activities while at the same time recognizing and respecting their inherent differences, (vi) how to organize the stewardship of nuclear data and the processes of nuclear data dissemination in an efficient, technically advanced and yet cost effective manner, and (vii) how the data processing tasks should be allocated between server and client computers

    Full Text Available Purpose: With the rapid progress of Internet of Things technology, the information service of IoT has got unprecedented development, and plays an increasingly important role in real life. For the increasing demand of information service, the pricing of information service becomes more important. This paper aims to analyze the strategic options and payoff function between information provider and intermediaries based on Stackelberg game. Firstly, we describe information service delivery method based on the Internet of Things specific function. Secondly, we calculate the consumer demand for the information service. Finally, we explain two kinds of strategic options by the game theory, and then discuss the optimal pricing method of information services based on profit maximization.Design/methodology/approach: To achieve this objective, Considering the consumer perceived value of Internet of Things Service changing, we establish a Stackelberg model in which the supplier is the leader followed by the middleman. Then, we compare the advantages of using individual pricing with that of bundling pricing.Findings: The results show that whether information providers adopt bundling pricing strategy or individual pricing strategy depends on the cost of perception equipment, if information providers want to adopt individual pricing strategy, the variation of consumers’ perception value of information services must meet certain conditions.Research limitations/implications: the providers make price for the information service, in addition to continuously improve the quality of information service, it also devotes resources to tapping and understanding market information, such as the sensor device price, the variation of perception value of information services and so on, so as to create competitive advantage. This paper is just a preliminary model, it does not take into account the effect of mixed bundling.Originality/value: In this research, a new model for

    Full Text Available Public authorities and national healthcare service providers across the European Union and beyond are increasingly under pressure to deliver better services with diminishing resources. Users, quite rightly, demand a high standard of service and increasingly also convenience focused on the needs of the users rather than how the services are organised to deliver them. Users, on the whole, also prefer to be supported in their homes, and be free to move as much as possible. While users without impairments and generally well provided for, there are increasingly also users who have special needs, including the aged and those with a range of physical and mental disabilities who are unable to make effective use of such services from their homes due to the lack of proactive and accessible services. The idea we promote in the chapter is to provide better support to users with disabilities and impairments from the comfort of their home by means of providing them with a set of scalable services which can be either offered for free or purchased through some central form of a marketplace repository.

    In Japan over the past few years, more attention has been focused on unnoticed solitary death in the context of an aging society and the trend toward nuclear family. A number of institutions and companies have implemented a prevention measure with digital terrestrial broadcasting telecare services for the elderly: Hokkaido University; TV-Asahi Corporation; Hitachi, Ltd; Iwamizawa City; Hokkaido Television Broadcasting Co, Ltd; and Hamanasu Information Co, Ltd. Although this system is provided free of charge as a demonstration test, determining the appropriate price for the service is required for its sustainable operation. The aim of this study was to quantify individual willingness to pay (WTP) so as to test the tenability of digital terrestrial broadcasting service for elderly telecare. We used the contingent valuation method (CVM) to estimate the WTP for this service among 305 citizens (valid response rate 76.0%) living in Japan. A questionnaire survey was conducted for people aged 18 to 100 years according to Japanese age distribution from September 2016. To elicit WTP, we adopted a double-bound dichotomous choice method to ask the respondents whether they agree or disagree with the price we offered. The median WTP for this service's monthly fee is estimated to be 431 JPY (approximately US $3.7). The finding suggests that gender (0.66, P=.01), health consciousness (1.08, P=.01), willingness to use (2.38, PWTP. We conclude that reliable WTP was elicited by CVM based on an Internet survey. Calculated median WTP for digital terrestrial broadcasting service for elderly telecare was 431 JPY (approximately US $3.7). In the analysis of factors that affect WTP, constant factors, log-bid, health consciousness, gender, see others less than one time for week, and willingness to use made positive effect to probability of acceptance. In comparison of WTP in different groups, age groups showed that WTP of the elderly group was higher than WTP of the middle age group and

    2016-03-11

    The Internet of Things (IoT) is becoming increasingly important in several fields of industrial applications and personal applications, such as medical e-health, smart cities, etc. The research into protocols and security aspects related to this area is continuously advancing in making these networks more reliable and secure, taking into account these aspects by design. Bootstrapping is a procedure by which a user obtains key material and configuration information, among other parameters, to operate as an authenticated party in a security domain. Until now solutions have focused on re-using security protocols that were not developed for IoT constraints. For this reason, in this work we propose a design and implementation of a lightweight bootstrapping service for IoT networks that leverages one of the application protocols used in IoT : Constrained Application Protocol (CoAP). Additionally, in order to provide flexibility, scalability, support for large scale deployment, accountability and identity federation, our design uses technologies such as the Extensible Authentication Protocol (EAP) and Authentication Authorization and Accounting (AAA). We have named this service CoAP-EAP. First, we review the state of the art in the field of bootstrapping and specifically for IoT. Second, we detail the bootstrapping service: the architecture with entities and interfaces and the flow operation. Third, we obtain performance measurements of CoAP-EAP (bootstrapping time, memory footprint, message processing time, message length and energy consumption) and compare them with PANATIKI. The most significant and constrained representative of the bootstrapping solutions related with CoAP-EAP. As we will show, our solution provides significant improvements, mainly due to an important reduction of the message length.

Additionally, in order to provide flexibility, scalability, support for large scale deployment, accountability and identity federation, our design uses technologies such as the Extensible Authentication Protocol (EAP and Authentication Authorization and Accounting (AAA. We have named this service CoAP-EAP. First, we review the state of the art in the field of bootstrapping and specifically for IoT. Second, we detail the bootstrapping service: the architecture with entities and interfaces and the flow operation. Third, we obtain performance measurements of CoAP-EAP (bootstrapping time, memory footprint, message processing time, message length and energy consumption and compare them with PANATIKI. The most significant and constrained representative of the bootstrapping solutions related with CoAP-EAP. As we will show, our solution provides significant improvements, mainly due to an important reduction of the message length.

    Since the introduction of mobile telephony the exposure of the population to radiofrequency electromagnetic fields (in the frequency range 30 kHz to 300 GHz) has risen considerably. Due not least to inconclusive results from a wide range of research activities this new technology has triggered an extremely controversial discussion on the health risks associated with radiofrequency electromagnetic fields. In late 1999 already some 25% of the population, and in the year 2000 around 50% of all households used a mobile phone. In 2002 more than 71% of the German population in the age range from 14 to 64 years owned a mobile phone. The need for further research on the health effects of such exposure is substantiated by the public concern over this issue, its widespread presence since the introduction of mobile telephony and the inconsistency of results obtained so far

    Despite caring for large numbers of older adults, prehospital emergency medical services (EMS) providers receive minimal geriatrics-specific training while obtaining their certification. Studies have shown that they desire further training to improve their comfort level and knowledge in caring for older adults, but continuing education programs to address these needs must account for each EMS provider's specific needs, consider each provider's learning styles, and provide an engaging, interactive experience. A novel, Internet-based, video podcast-based geriatric continuing education program was developed and implemented for EMS providers, and their perceived value of the program was evaluated. They found this resource to be highly valuable and were strongly supportive of the modality and the specific training provided. Some reported technical challenges and the inability to engage in a discussion to clarify topics as barriers. It was felt that both of these barriers could be addressed through programmatic and technological revisions. This study demonstrates the proof of concept of video podcast training to address deficiencies in EMS education regarding the care of older adults, although further work is needed to demonstrate the educational effect of video podcasts on the knowledge and skills of trainees. © 2012, Copyright the Authors Journal compilation © 2012, The American Geriatrics Society.

  10. Green Data Gathering under Delay Differentiated Services Constraint for Internet of Things

    Full Text Available Energy-efficient data gathering techniques play a crucial role in promoting the development of smart portable devices as well as smart sensor devices based Internet of Things (IoT. For data gathering, different applications require different delay constraints; therefore, a delay Differentiated Services based Data Routing (DSDR scheme is creatively proposed to improve the delay differentiated services constraint that is missed from previous data gathering studies. The DSDR scheme has three advantages: first, DSDR greatly reduces transmission delay by establishing energy-efficient routing paths (E2RPs. Multiple E2RPs are established in different locations of the network to forward data, and the duty cycles of nodes on E2RPs are increased to 1, so the data is forwarded by E2RPs without the existence of sleeping delay, which greatly reduces transmission latency. Secondly, DSDR intelligently chooses transmission method according to data urgency: the direct-forwarding strategy is adopted for delay-sensitive data to ensure minimum end-to-end delay, while wait-forwarding method is adopted for delay-tolerant data to perform data fusion for reducing energy consumption. Finally, DSDR make full use of the residual energy and improve the effective energy utilization. The E2RPs are built in the region with adequate residual energy and they are periodically rotated to equalize the energy consumption of the network. A comprehensive performance analysis demonstrates that the DSDR scheme has obvious advantages in improving network performance compared to previous studies: it reduces transmission latency of delay-sensitive data by 44.31%, reduces transmission latency of delay-tolerant data by 25.65%, and improves network energy utilization by 30.61%, while also guaranteeing the network lifetime is not lower than previous studies.

    Full Text Available One of the pillars of the technological revolution that began in the seventies was the development of the Internet. This network has evolved in such a way that it now forms a complex structure that radically changed the social and economic dynamics at the end of century XX. Nowadays, new technologies allow anything from communication and information exchange to the realization of complex financial transactions, all from anywhere in the world and almost instantaneously. In spite of the widespread use of the Internet, there are still territories and inhabitants, mostly emplaced in remote rural areas, who live outside of this technological revolution. By contrast, urban areas enjoy a privileged position in the dissemination of the information society by concentrating most of the telecommunications infrastructure and monopolize the most qualified people. But there are many disparities in terms of diffusion of new technologies and these will transfer, in turn, to the enterprise sector which is the subject of this research. The differences in the use of new technologies and more specifically the use of advanced services on the Internet are related to the sector where the population is employed and its level of training. One of the advanced services offered by the Network is teleworking. Nowadays there are companies that offer their employees the opportunity to develop their professional activities outside their headquarters, using their homes as an alternative or call centers enabled with computers and Internet access. The purpose of this research is the study of the consumption of Internet advanced services by companies in the metropolitan area of Madrid, analyzing the spread of telework in more detail,a potential offered by new technologies and which may modify the current pattern of mobility in the main urban areas because it is from here where big companies are guiding the global economy.

    A common measure to save energy in buildings is the adjustment of the operating time of the building service facilities to the busy time of the building (i.e. lowering period). For lack of better resources, the general lowering periods in irregularly occupied buildings often are reduced to a minimum or the adjustment of the operating time is completely missing. In order to adjust the operating time optimally to the actual busy time, an internet-based booking system has been developed, which allows users to register a room assignment online. This booking system is linked with the building service facilities. This ensure the optimal setting of the lowering periods and therefore allows saving energy. The technical implementation resulted from a programmable logic controller (PLC) that can be accessed via a web browser. Temperature offset boxes have been added as interface between the PLC and the existing facilities in order that the system is applicable in existing buildings too. The booking system has been installed in two test objects and has also been successfully tested with the responsible staff (caretaker, real estate management). The booking system may be contemplated online: http://www.hetag.ch. (author)

    This paper describes our conceptual framework of closed-loop lifecycle information sharing for product-service in the Internet of Things (IoT). The framework is based on the ontology model of product-service and a type of IoT message standard, Open Messaging Interface (O-MI) and Open Data Format (O-DF), which ensures data communication. (1) BACKGROUND: Based on an existing product lifecycle management (PLM) methodology, we enhanced the ontology model for the purpose of integrating efficiently the product-service ontology model that was newly developed; (2) METHODS: The IoT message transfer layer is vertically integrated into a semantic knowledge framework inside which a Semantic Info-Node Agent (SINA) uses the message format as a common protocol of product-service lifecycle data transfer; (3) RESULTS: The product-service ontology model facilitates information retrieval and knowledge extraction during the product lifecycle, while making more information available for the sake of service business creation. The vertical integration of IoT message transfer, encompassing all semantic layers, helps achieve a more flexible and modular approach to knowledge sharing in an IoT environment; (4) Contribution: A semantic data annotation applied to IoT can contribute to enhancing collected data types, which entails a richer knowledge extraction. The ontology-based PLM model enables as well the horizontal integration of heterogeneous PLM data while breaking traditional vertical information silos; (5) CONCLUSION: The framework was applied to a fictive case study with an electric car service for the purpose of demonstration. For the purpose of demonstrating the feasibility of the approach, the semantic model is implemented in Sesame APIs, which play the role of an Internet-connected Resource Description Framework (RDF) database.

    Full Text Available This study aims at analyzing the variables of use and contact of users regarding to products and services of mobile phone technology. Technological innovation stands in the enterprise, enabling growth and creation of new products and services. In the theoretical framework, we used the technology readiness model, from users beliefs and feelings represented by four dimensions: optimism, innovativeness, discomfort and insecurity. It also highlights the technology acceptance model and presents two important constructs as perceived usefulness and ease of use. In short, the factors that support the technology readiness model could be preceding the technology acceptance model. To conduct this study, a field survey of students at the Federal University of Uberlândia / Campus FACIP was carried out. Results indicate optimism as the main factor to accept new mobile technology, due to the fact that the mobile devices provide benefits to people's lives and prompt them a positive attitude toward mobile technology. The perception of the user to purchase a mobile device is directly related to its usefulness and ease of handling of the technology.

    Full Text Available The world is facing a global financial and economic crisis, the deepest and the widest spread since the Great Depression of 1930. Individuals, companies and governments alike are forced to take active measures to counteract the severe consequences of the crisis, if they want to emerge stronger from this difficult period. There are strong beliefs among policy makers around the world, European Union included, that the Information and Communication Technologies are a very important pillar in the recovery from the crisis. This paper aims at evaluating the e-banking services, internet enabled conferencing solutions and electronic public services as categories of ICT enabled services that represent powerful and practical solutions, especially in time of crisis, with significant advantages at individual, company and government level.

It is well perceived that information and communication technologies have great impacts on modern society - they are changing how and where we work, shop, and in general terms how we live our lives. In this study, we use a survey instrument to examine the association between experience level with Internet and e-shopping and consumers’ frequency of online purchasing, while considering sex as a passive influencer. We study these relationships in a multinomial logistic regression model that is aimed at online retailers to help them improve their understanding of their consumers’ characteristics and propensity to buy through Internet retailing. Tracking the online journey of consumers will help enhance the attractiveness of this new retailing medium to current and potential customers.

    Ensuring rapid access to high quality sexual health services is a key public health objective, both in the United Kingdom and internationally. Internet-based testing services for sexually transmitted infections (STIs) are considered to be a promising way to achieve this goal. This study will evaluate a nascent online STI testing and results service in South East London, delivered alongside standard face-to-face STI testing services. The aim of this study is to establish whether an online testing and results services can (1) increase diagnoses of STIs and (2) increase uptake of STI testing, when delivered alongside standard face-to-face STI testing services. This is a single-blind randomized controlled trial. We will recruit 3000 participants who meet the following eligibility criteria: 16-30 years of age, resident in the London boroughs of Lambeth and Southwark, having at least one sexual partner in the last 12 months, having access to the Internet and willing to take an STI test. People unable to provide informed consent and unable to read and understand English (the websites will be in English) will be excluded. Baseline data will be collected at enrolment. This includes participant contact details, demographic data (date of birth, gender, ethnicity, and sexual orientation), and sexual health behaviors (last STI test, service used at last STI test and number of sexual partners in the last 12 months). Once enrolled, participants will be randomly allocated either (1) to an online STI testing and results service (Sexual Health 24) offering postal self-administered STI kits for chlamydia, gonorrhoea, syphilis, and HIV; results via text message (short message service, SMS), except positive results for HIV, which will be delivered by phone; and direct referrals to local clinics for treatment or (2) to a conventional sexual health information website with signposting to local clinic-based sexual health services. Participants will be free to use any other interventions

    The transition to a largely Internet and Web-based environment for dissemination of health information has changed the health information landscape and the framework for evaluation of such activities. A multidimensional evaluative approach is needed. This paper discusses one important dimension of Web evaluation-usage data. In particular, we discuss the collection and analysis of external data on website usage in order to develop a better understanding of the health information (and related US government information) market space, and to estimate the market share or relative levels of usage for National Library of Medicine (NLM) and National Institutes of Health (NIH) websites compared to other health information providers. The primary method presented is Internet audience measurement based on Web usage by external panels of users and assembled by private vendors-in this case, comScore. A secondary method discussed is Web usage based on Web log software data. The principle metrics for both methods are unique visitors and total pages downloaded per month. NLM websites (primarily MedlinePlus and PubMed) account for 55% to 80% of total NIH website usage depending on the metric used. In turn, NIH.gov top-level domain usage (inclusive of NLM) ranks second only behind WebMD in the US domestic home health information market and ranks first on a global basis. NIH.gov consistently ranks among the top three or four US government top-level domains based on global Web usage. On a site-specific basis, the top health information websites in terms of global usage appear to be WebMD, MSN Health, PubMed, Yahoo! Health, AOL Health, and MedlinePlus. Based on MedlinePlus Web log data and external Internet audience measurement data, the three most heavily used cancer-centric websites appear to be www.cancer.gov (National Cancer Institute), www.cancer.org (American Cancer Society), and www.breastcancer.org (non-profit organization). Internet audience measurement has proven useful to NLM

    Cloud computing is the new enabling technology that offers centralised computing, flexible data storage and scalable services. In the manufacturing context, it is possible to utilise the Cloud technology to integrate and provide industrial resources and capabilities in terms of Cloud services. In this paper, a function block-based integration mechanism is developed to connect various types of production resources. A Cloud-based architecture is also deployed to offer a service pool which maintains these resources as production services. The proposed system provides a flexible and integrated information environment for the Cloud-based production system. As a specific type of manufacturing, Waste Electrical and Electronic Equipment (WEEE) remanufacturing experiences difficulties in system integration, information exchange and resource management. In this research, WEEE is selected as the example of Internet of Things to demonstrate how the obstacles and bottlenecks are overcome with the help of Cloud-based informatics approach. In the case studies, the WEEE recycle/recovery capabilities are also integrated and deployed as flexible Cloud services. Supporting mechanisms and technologies are presented and evaluated towards the end of the paper.

    Full Text Available Abstract Background The application of Willingness To Pay (WTP measurement with Contingent Valuation Method (CVM to medical services is gradually increasing. Knowing what influences WTP is an important matter because validity of CVM in medical services remains controversial. The objective of this survey is to measure WTP for the treatment of typical acute illnesses and to analyze the factors affecting WTP. Methods A questionnaire survey was conducted over the Internet, in which 795 men and women between 40 and 59 years old responded to questions about WTP for medical expenses in three hypothetical scenarios: common cold (CC, retinal detachment (RD and myocardiac infarction (MI. Results Mean WTP was $29.9 for CC, $2,233 for RD, and $8,976 for MI. WTP for RD and MI was lower in the low-income group. While WTP for CC did not vary with income, WTP was higher in groups whose current subjective fitness levels were low. Conclusion Although WTP measurements are criticized frequently for their validity and reliability, they are still useful for determining the economic value of medical services. Based on the results of this study, it is deemed necessary to enhance safety nets for low-income earners in regards to serious illnesses that incur high medical expenses. Further, it is recommended that the rate of co-payments be set relatively high with respect to mild illnesses for which alternative services are available.

This article presents a discourse analysis of 101 responses to 98 questions that were posted on 14 different Internet-based mental health services in Norway and Sweden. We aimed to examine and describe the dominant understandings and favored recommendations in the services’ answers, and we reflected upon the social consequences of those answers. The services generally understood life struggles as an abnormal state of mind, life rhythms, or self-reinforcing loops. Internet-based mental health services primarily counsel service users to seek help, talk to health care professionals face-to-face, and discuss their life struggles openly and honestly. They also urge service users to take better care of themselves and socialize with other people. However, such answers might enhance the individualization of life problems, masking social origin and construction. Consequently, the services are challenged to include social explanations in their answers and strengthen their responsibility to amplify peoples’ messages at a societal level. Potentially, such answers could strengthen democratic structures and put pressure on social equity.Keywords: depression, e-mental health, health psychology, Internet, public health

    The term “internet sexuality” (or OSA, online sexual activities) refers to sexual-related content and activities observable on the internet (cf. Adams, Oye, & Parker, 2003; Cooper, McLoughlin, & Campbell, 2000; Leiblum & Döring, 2002). It designates a variety of sexual phenomena (e.g., pornography, sex education, sexual contacts) related to a wide spectrum of online services and applications (e.g., websites, online chat rooms, peer-to-peer networks). If an even broader range of computer networks - such as the Usenet or bulletin board systems - is included in this extensional definition, one speaks of “online sexuality” or “cybersexuality.”

    Despite the growing evidence of the benefits of physical activity (PA) in individuals with rheumatoid arthritis (RA), the majority is not physically active enough. An innovative strategy is to engage lead users in the development of PA interventions provided over the internet. The aim was to explore lead users' ideas and prioritization of core features in a future internet service targeting adoption and maintenance of healthy PA in people with RA. Six focus group interviews were performed with a purposively selected sample of 26 individuals with RA. Data were analyzed with qualitative content analysis and quantification of participants' prioritization of most important content. Six categories were identified as core features for a future internet service: up-to-date and evidence-based information and instructions, self-regulation tools, social interaction, personalized set-up, attractive design and content, and access to the internet service. The categories represented four themes, or core aspects, important to consider in the design of the future service: (1) content, (2) customized options, (3) user interface and (4) access and implementation. This is, to the best of our knowledge, the first study involving people with RA in the development of an internet service to support the adoption and maintenance of PA.Participants helped identifying core features and aspects important to consider and further explore during the next phase of development. We hypothesize that involvement of lead users will make transfer from theory to service more adequate and user-friendly and therefore will be an effective mean to facilitate PA behavior change.

    Full Text Available Recently, with multimedia services such as IPTV, video conferencing has emerged as a main traffic source. When UDP coexists with TCP, it induces not only congestion collapse but also an unfairness problem. In this paper, a new Active Queue Management algorithm, called Traffic Sensitive Active Queue Management (TSAQM, is proposed for providing multimedia services in routers. The TSAQM is comprised of Dynamic Weight Allocate Scheme (DWAS and Service Guarantee Scheme (SGS. The purpose of DWAS is to fairly allocate resources with high end-user utility, and the SGS is to determine the satisfactory threshold (TH and threshold region (TR. Besides, a multiqueue design for different priority traffic, and threshold TH and threshold region TR is proposed to achieve the different QoS requirements. Several objectives of this proposed scheme include achieving high end user utility for video services, considering the multicast as well as unicast proprieties to meet interclass fairness, and achieving the QoS requirement by adaptively adjusting the thresholds based on the traffic situations. Performance comparisons with the GRED-I are in terms of packet dropping rate and throughput to highlight the better behavior of the proposed schemes due to taking into account the fairness and different weights for video layers.

To investigate the perspectives of young people who self-injure regarding online services, with the aim of informing online service delivery. A mixed-methods exploratory analysis regarding the perspectives of a subsample of young people who reported a history of self-injury and responded to questions regarding preferences for future online help-seeking (N = 457). The sample was identified as part of a larger study (N = 1,463) exploring self-injury and help-seeking. Seven themes emerged in relation to preferences for future online help-seeking: information, guidance, reduced isolation, online culture, facilitation of help-seeking, access, and privacy. Direct contact with a professional via instant messaging was the most highly endorsed form of online support. Young people expressed clear preferences regarding online services for self-injury, supporting the importance of consumer consultation in development of online services.

    Current generation wireless sensor routing algorithms and protocols have been designed based on a myopic routing approach, where the motes are assumed to have the same sensing and communication capabilities. Myopic routing is not a natural fit for the IoT, as it may lead to energy imbalance and subsequent short-lived sensor networks, routing the sensor readings over the most service-intensive sensor nodes, while leaving the least active nodes idle. This paper revisits the issue of energy efficiency in sensor networks to propose a clustering model where sensor devices' service delivery is mapped into an energy awareness model, used to design a clustering algorithm that finds service-aware clustering (SAC) configurations in IoT settings. The performance evaluation reveals the relative energy efficiency of the proposed SAC algorithm compared to related routing algorithms in terms of energy consumption, the sensor nodes' life span and its traffic engineering efficiency in terms of throughput and delay. These include the well-known low energy adaptive clustering hierarchy (LEACH) and LEACH-centralized (LEACH-C) algorithms, as well as the most recent algorithms, such as DECSA and MOCRN.

    Background In Japan over the past few years, more attention has been focused on unnoticed solitary death in the context of an aging society and the trend toward nuclear family. A number of institutions and companies have implemented a prevention measure with digital terrestrial broadcasting telecare services for the elderly: Hokkaido University; TV-Asahi Corporation; Hitachi, Ltd; Iwamizawa City; Hokkaido Television Broadcasting Co, Ltd; and Hamanasu Information Co, Ltd. Although this system is provided free of charge as a demonstration test, determining the appropriate price for the service is required for its sustainable operation. Objective The aim of this study was to quantify individual willingness to pay (WTP) so as to test the tenability of digital terrestrial broadcasting service for elderly telecare. Methods We used the contingent valuation method (CVM) to estimate the WTP for this service among 305 citizens (valid response rate 76.0%) living in Japan. A questionnaire survey was conducted for people aged 18 to 100 years according to Japanese age distribution from September 2016. To elicit WTP, we adopted a double-bound dichotomous choice method to ask the respondents whether they agree or disagree with the price we offered. Results The median WTP for this service’s monthly fee is estimated to be 431 JPY (approximately US $3.7). The finding suggests that gender (0.66, P=.01), health consciousness (1.08, P=.01), willingness to use (2.38, PCalculated median WTP for digital terrestrial broadcasting service for elderly telecare was 431 JPY (approximately US $3.7). In the analysis of factors that affect WTP, constant factors, log-bid, health consciousness, gender, see others less than one time for week, and willingness to use made positive effect to probability of acceptance. In comparison of WTP in different groups, age groups showed that WTP of the elderly group was higher than WTP of the middle age group and younger age group. However, WTP surveys need to

    The National Infrastructure Simulations and Analysis Center (NISAC) has developed a nationwide model of the Internet to study the potential impact of the loss of physical facilities on the network and on other infrastructures that depend on the Internet for services. The model looks at the Internet from the perspective of Internet Service Providers (ISPs) and their connectivity and can be used to determine how the network connectivity could be modified to assist in mitigating an event. In addition the model could be used to explore how portions of the network could be made more resilient to disruptive events.

    Objective: To introduce the development strategy of " Internet Plus" AIDS prevention services and its implementation results from 2010 to 2015 in Guangzhou, China. Methods: A gay men's health column was created for an active website aimed at men who have sex with men(MSM), in collaboration with local community organizations and the Guangzhou CDC. We designed intervention tools(including scenario-based applications and HIV risk self-assessment systems)and an online HIV testing service platform, integrated with applied psychology and behavioral theory as well as the " Internet Plus" concept, to intervene in HIV infection risk factors among MSM. Data of clients who accessed the " Internet Plus" AIDS services from 2010 to 2015 were used to evaluate service operation. Six-year consecutive surveys, conducted between April and July of each service year, were collected using a national AIDS sentinel surveillance questionnaire. For each year of surveillance, information on HIV prevalence, HIV interventions received during the past year, unprotected anal intercourse in the past 6 months, and HIV testing in the past year were compared using the chi-squared(χ 2 )test, to roughly reflect the effect of"Internet Plus" AIDS prevention services. Results: As of 31 December 2015, a total of 34 395 MSM had received " Internet Plus" services and HIV testing. The number of MSM tested increased from 2 338 in 2010 to 8 054 in 2015. From 2010 to 2015, newly identified HIV cases in each year were 59, 166, 312, 283, 291, and 270, which accounted for 25.0%, 32.8%, 38.8%, 35.1%, 30.5%, and 23.2% of MSM HIV cases of Guangzhou, respectively. Sentinel surveillance data showed that during the study period, 3 047 MSM were investigated, with 405, 400, 401, 633, 608, and 600 each year, respectively. The proportion of participants who had received any HIV intervention during the past year was 74.3%(301), 70.8%(283), 83.3%(334), 85.0%(538), 69.1%(420), and 83.8%(503)each year, respectively(trend χ 2

    Full Text Available Recently, many video applications like video telephony, video conferencing, Video-on-Demand (VoD, and so forth have produced heterogeneous consumers in the Internet. In such a scenario, media servers play vital role when a large number of concurrent requests are sent by heterogeneous users. Moreover, the server and distributed client systems participating in the Internet communication have to provide suitable resources to heterogeneous users to meet their requirements satisfactorily. The challenges in providing suitable resources are to analyze the user service pattern, bandwidth and buffer availability, nature of applications used, and Quality of Service (QoS requirements for the heterogeneous users. Therefore, it is necessary to provide suitable techniques to handle these challenges. In this paper, we propose a framework for peer-to-peer- (P2P- based VoD service in order to provide effective video streaming. It consists of four functional modules, namely, Quality Preserving Multivariate Video Model (QPMVM for efficient server management, tracker for efficient peer management, heuristic-based content distribution, and light weight incentivized sharing mechanism. The first two of these modules are confined to a single entity of the framework while the other two are distributed across entities. Experimental results show that the proposed framework avoids overloading the server, increases the number of clients served, and does not compromise on QoS, irrespective of the fact that the expected framework is slightly reduced.

    Remote and rural regions in Canada are faced with unique challenges in the delivery of primary health services. The purpose of this study was to understand how patients and healthcare professionals in northern British Columbia might make use of the Internet to manage cardiovascular diseases. The study used a qualitative methodology. Eighteen health professionals and 6 patients were recruited for a semi-structured interview that explored their experience in managing patients with cardiovascular disease and their opinions and preferences about the use of the Internet in chronic disease management. Key findings from the data suggest that a) use of the Internet helps to maintain continuity of care while a patient moves through various stages of care, b) the Internet may possibly be used as an educational tool in chronic disease self-management, c) there is a need for policy development to support Internet-based consultation processes, and d) while health providers endorse the notion of electronic advancement in their practice, the need for secure and stable electronic systems is essential.

    Full Text Available Studies on gender and telephony tend to be quantitative and depict the purposes for which women and men use mobile telephones and landlines. Qualitative studies on the topic predominantly rely on face-to-face interviews to examine how telephone use genders space. We suggest these traditional methods of data collection leave unexamined the emotional and social relationships that emerge and are enabled by telephone use, which at times reconfigure and gender social spaces. In this article we present a collaborative autoethnographic inquiry based on our own telephone lives. We introduce a reflexive visual and textual methodological design, specifically diary notes, memory work, and photography, developed from our lives as researcher and researched. We examine an important theme in our findings, the physical placement of the telephone and the phone holder's awareness of the physicality of the telephone, which illustrates the importance of our methodological choices. We show how the placement of the phone by the users both genders space and creates emotional spaces.

    Over the past decade, the increasing availability of the World Wide Web has held out the possibility that the efficiency of scientific measurements could be enhanced in cases where experiments were being conducted at distant facilities. Examples of early successes have included X-ray diffraction (XRD) experimental measurements of protein crystal structures at synchrotrons and access to scanning electron microscopy (SEM) and NMR facilities by users from institutions that do not possess such advanced capabilities. Experimental control, visual contact, and receipt of results has used some form of X forwarding and/or VNC (virtual network computing) software that transfers the screen image of a server at the experimental site to that of the users' home site. A more recent development is a web services platform called Science Studio that provides teams of scientists with secure links to experiments at one or more advanced research facilities. The software provides a widely distributed team with a set of controls and screens to operate, observe, and record essential parts of the experiment. As well, Science Studio provides high speed network access to computing resources to process the large data sets that are often involved in complex experiments. The simple web browser and the rapid transfer of experimental data to a processing site allow efficient use of the facility and assist decision making during the acquisition of the experimental results. The software provides users with a comprehensive overview and record of all parts of the experimental process. A prototype network is described involving X-ray beamlines at two different synchrotrons and an SEM facility. An online parallel processing facility has been developed that analyzes the data in near-real time using stream processing. Science Studio and can be expanded to include many other analytical applications, providing teams of users with rapid access to processed results along with the means for detailed

    The Internet and emergent telecommunications infrastructures are transforming the future of health care management. The costs of health care delivery systems, products, and services continue to rise everywhere, but performance of health care delivery is associated with institutional and ideological considerations as well as availability of financial and technological resources. to identify the effects of ideological differences on health care market infrastructures including the Internet and telecommunications technologies by a comparative case analysis of two large health care organizations: the British National Health Service and the California-based Kaiser Permanente health maintenance organization. A qualitative comparative analysis focusing on the British National Health Service and the Kaiser Permanente health maintenance organization to show how system infrastructures vary according to market dynamics dominated by health care institutions ("push") or by consumer demand ("pull"). System control mechanisms may be technologically embedded, institutional, or behavioral. The analysis suggests that telecommunications technologies and the Internet may contribute significantly to health care system performance in a context of ideological diversity. The study offers evidence to validate alternative models of health care governance: the national constitution model, and the enterprise business contract model. This evidence also suggests important questions for health care policy makers as well as researchers in telecommunications, organizational theory, and health care management.

    Abstract Background Korean Neuropsychiatric Association changed the Korean term for schizophrenia from ‘split-mind disorder’ to ‘attunement disorder’ in 2012, to dispel the stigma associated with name, and to promote early detection and treatment. Information on the internet affects the public awareness and attitude toward schizophrenia. The main purpose of this study was to investigate the correlation between renaming schizophrenia and the pattern of mental health services utilization by big data analysis of internet (newspaper articles and internet searches) in Korea. Methods From January 2016 to September 2017, newspaper articles on “attunement disorder” and “split-mind disorder” available on the internet were classified as related with negative images like crime and helpful or positive in dispelling the stigma. The relationship between the number of anti-stigma newspaper articles and newspaper articles of schizophrenia containing both positive and negative images was examined. In addition, using Naver, a major internet search engine in Korea, we investigated the total number of internet searches of both old and new name of schizophrenia by gender differences. Finally, the frequency of the visits of mental health services of patients with schizophrenia was measured using the Korean Healthcare Bigdata Hub (http://opendata.hira.or.kr/home.do#none) for 14 months and the correlation between the frequency of the visits and the above big data was examined. The data were analyzed using the SPSS/WIN 24.0. Pearson correlation coefficients were used to analyze correlations. Results The amounts of newspaper articles containing anti-stigma of schizophrenia were correlated with the amounts of newspaper articles containing negative images like crime of the new name (attunement disorder) of schizophrenia (r=0.528, p0.05) in next month was larger than the correlation of “split-mind disorder” searches with mental health services utilization (r = 0.082, p>0

    2012-03-01

    The relationship between health information seeking, patient engagement and health literacy is not well understood. This is especially true in medically underserved populations, which are often viewed as having limited access to health information. To improve communication between an urban health centre and the community it serves, a team of library and information science researchers undertook an assessment of patients' level and methods of access to and use of the Internet. Data were collected in 53 face-to-face anonymous interviews with patients at the centre. Interviews were tape-recorded for referential accuracy, and data were analysed to identify patterns of access and use. Seventy-two percentage of study participants reported having access to the Internet through either computers or cell phones. Barriers to Internet access were predominantly lack of equipment or training rather than lack of interest. Only 21% of those with Internet access reported using the Internet to look for health information. The findings suggest that lack of access to the Internet in itself is not the primary barrier to seeking health information in this population and that the digital divide exists not at the level of information access but rather at the level of information use. © 2011 The authors.

    The present study developed and tested a model that explains how people who believe that others have unrealistically high standards and exert pressure on them to be perfect (that is, people high in socially prescribed perfectionism) develop a problematic use of internet communicative services (GPIU). Following the perfectionism social disconnection model and previous evidence about the role that the online environment might play in the development of problematic internet use, low reported social support and the fear of negative evaluations in face to face interactions were hypothesized to mediate the association between socially prescribed perfectionism and GPIU. A sample of 465 undergraduate students was recruited (240 F; mean age 21.91+2.23years), and the hypotheses were tested through structural equation modeling separately for men and women. Among men, the association between SPP and GPIU was fully mediated by the fear of being negatively evaluated and the perception of low social support. For women, we found a partially mediated model in which SPP affected GPIU indirectly through the fear of negative evaluations. The presence of a direct effect of SPP on GPIU was also found. Moreover, perceived social support was not found to be a significant mediator among women. The findings suggest that problematic use of internet communicative services might be, at least in part, a defensive response to extreme social evaluation pressures. Copyright © 2014 Elsevier Ltd.

    Cloud computing is changing the ways software is developed and managed in enterprises, which is changing the way of doing business in that dynamically scalable and virtualized resources are regarded as services over the Internet. Traditional manufacturing systems such as supply chain management (SCM), customer relationship management (CRM), and enterprise resource planning (ERP) are often developed case by case. However, effective collaboration between different systems, platforms, programming languages, and interfaces has been suggested by researchers.

    Full Text Available In the current moment that we are living now, the use of Big Data is taken a strength and a very important relevance. The biggest companies of social sector and service sector are using Big Data technologies that allow to store and treat all the information that they have of users and, in a second way, the incorporation of the knowledge of the treatment of this information in the life of the users, in the way of improve the services offered and go to the next step in the relationship of customer/company. In telecare, with the IP technology in Telecare Unit, the communication between the unit and control centre will be done using internet instead of telephony cable. The companies will start to use these technologies to store all the information that the unit will send to the control center. With all this information, the companies will be able to discover patterns of user’s behavior, detect some illnesses like, for example, alzheimer. The most important action that the companies will be able to have is to have more information related to the situation of all devices and sensors installed in user’s home when the emergency alarm is raised.

    In the present study, the TUNEL (Terminal deoxynucleotide transferase dUTP Nick End Labeling) assay '' a well known technique widely used for detecting fragmented DNA in various types of cells'' was used to detect cell death (DNA fragmentation) in a biological model, the early and mid stages of oogenesis of the insect Drosophila melanogaster. The flies were exposed in vivo to either GSM 900-MHz (Global System for Mobile telecommunications) or DCS 1800-MHz (Digital Cellular System) radiation from a common digital mobile phone, for few minutes per day during the first 6 days of their adult life. The exposure conditions were similar to those to which a mobile phone user is exposed, and were determined according to previous studies of ours [D.J. Panagopoulos, A. Karabarbounis, L.H.

    2001-07-01

    Recently, the field of IP Telephony has been experienced considerable evolution through the specification of new protocols and introduction of products implementing these protocols. We visualize IP Telephony evolving to soon offer multiservices encompassing not only voice, but also data, video and multimedia. While the progress has focused on refining protocols and architectures, very little attention has been given to business models for offering these services. This paper introduces the concept of a Service Zone, which from a service provider/network operator perspective fits within the operator's administrative domain, but is viewed as an independent zone with its own management and services, requiring minimal integration with the core network services. Besides its own management, the Enhanced Services Zone may also provide provisioning and maintenance features needed to provide the customer services and availability that subscribers expect from a telephony service providers. The platform must provide reliable service over time, be scalable to meet increased capacity demands, and be upgradeable to incorporate advanced services and features as they become available. Signaling flows are illustrated using SIP and H.323.

    In-home health care services based on the Internet-of-Things are promising to resolve the challenges caused by the ageing of population. But the existing research is rather scattered and shows lack of interoperability. In this article, a business-technology co-design methodology is proposed for cross-boundary integration of in-home health care devices and services. In this framework, three key elements of a solution (business model, device and service integration architecture and information system integration architecture) are organically integrated and aligned. In particular, a cooperative Health-IoT ecosystem is formulated, and information systems of all stakeholders are integrated in a cooperative health cloud as well as extended to patients' home through the in-home health care station (IHHS). Design principles of the IHHS includes the reuse of 3C platform, certification of the Health Extension, interoperability and extendibility, convenient and trusted software distribution, standardised and secured electrical health care record handling, effective service composition and efficient data fusion. These principles are applied to the design of an IHHS solution called iMedBox. Detailed device and service integration architecture and hardware and software architecture are presented and verified by an implemented prototype. The quantitative performance analysis and field trials have confirmed the feasibility of the proposed design methodology and solution.

    Full Text Available Abstract Background The aim was to evaluate the effect of a 12-month individualized health coaching intervention by telephony on clinical outcomes. Methods An open-label cluster-randomized parallel groups trial. Pre- and post-intervention anthropometric and blood pressure measurements by trained nurses, laboratory measures from electronic medical records (EMR. A total of 2594 patients filling inclusion criteria (age 45 years or older, with type 2 diabetes, coronary artery disease or congestive heart failure, and unmet treatment goals were identified from EMRs, and 1535 patients (59% gave consent and were randomized into intervention or control arm. Final analysis included 1221 (80% participants with data on primary end-points both at entry and at end. Primary outcomes were systolic and diastolic blood pressure, serum total and LDL cholesterol concentration, waist circumference for all patients, glycated hemoglobin (HbA1c for diabetics and NYHA class in patients with congestive heart failure. The target effect was defined as a 10-percentage point increase in the proportion of patients reaching the treatment goal in the intervention arm. Results The proportion of patients with diastolic blood pressure initially above the target level decreasing to 85 mmHg or lower was 48% in the intervention arm and 37% in the control arm (difference 10.8%, 95% confidence interval 1.5–19.7%. No significant differences emerged between the arms in the other primary end-points. However, the target levels of systolic blood pressure and waist circumference were reached non-significantly more frequently in the intervention arm. Conclusions Individualized health coaching by telephony, as implemented in the trial was unable to achieve majority of the disease management clinical measures. To provide substantial benefits, interventions may need to be more intensive, target specific sub-groups, and/or to be fully integrated into local health care. Trial registration

    2015-08-01

    Full Text Available Internet of Vehicles (IoV is a leading technology of the present era. It has gained huge attention with respect to its implementation in wide variety of domains ranging from traffic safety to infotainment applications. However, IoV can also be extended to healthcare domain, where the patients can be provided healthcare services on-the-fly. We extend this novel concept in this paper and refer it as “Healthcare services on-the-fly”. The concept of game theory has been used among the vehicles to access the healthcare services while traveling. The vehicles act as players in the game and tend to form and split coalitions to access these services. Learning automata (LA act as the players for interaction with the environment and take appropriate actions based on reward and penalty. Apart from this, Virtual Machine (VM scheduling algorithm for efficient utilization of resources at cloud level has also been formulated. A stochastic reward net (SRN-based model is used to represent the coalition formation and splitting with respect to availability of resources at cloud level. The performance of the proposed scheme is evaluated using various performance evaluation metrics. The results obtained prove the effectiveness of the proposed scheme in comparison to the best, first, and random fit schemes.

    Full Text Available Taxi plays a crucial role in the transportation system because of the characteristic that can be hailed conveniently. Most of the taxi drivers obtain passengers by hunting on the road or waiting in a fixed taxi queuing point; however these methods have poor performance, high vacancy rate, and several critical problems such as air pollution and foul up traffic. This study proposed a taxi carrying management system by using location based services and zone queuing techniques on Internet of things. The proposed system allows drivers to both hunt on the road and wait in a queuing zone. A queuing table is used in the control center and neighbor tables are used in RSUs for zone queuing establishment. Joining and leaving mechanisms are developed for zone queuing management. To enhance service efficiency and quality, we present a scheme to prevent the ping-pong effect which is based on the location based services, a hunting rate calculation scheme, and a path planning service for taxi drivers according to the history carrying record. PRISM is used to simulate the proposed system, and the results indicated that our scheme outperforms the waiting and hunting models in terms of number of customers, vacancy rate, and profit.

    Circuit Emulation Service(CES)aims to enable packet switched networks to provide guaranteed services with comparable qualities of circuit switched networks.Our paper addresses the key issue of QoS of CES flows over Internet.Enlightened by the time division idea popularly used in circuit switched networks,we propose a time division based control mechanism to provide guaranteed QoS for the constant-rate CES flows.The control mechanism is able to estimate the arrival times of the coming packets in CES flows,and reserve the time slots for them.ACCOrdingly.it enables the packets to consume the reserved time slots of their own,so the CES flows are guaranteed to be processed.Refreshing Bloom Filter(RBF),an efficient data representation structure,is proposed to support the time division control mechanism.It consists of multiple bloom filters,and can efficiently record the arrival time slots of millions of packets.The proposed control system model could be a practical tool to support Circuit Emulation Services over Intemet.

    2012-01-01

    Internet addiction is defined as uncontrolled and harmful use of Internet, which manifests in three forms: gaming, various sexual activities and excessive use of emails, chats or SMS messaging. Several studies have found that abuse of alcohol and other substances, depression and other health problems are associated with Internet addiction. In boys and men depression may be more a consequence of the addiction than a cause for it. ADHD seems to be a significant background factor for developing the condition. Because it is almost impossible to lead a life without Internet and computers nowadays, it is unrealistic to aim towards full abstinence. Treatment has generally followed the guidelines adapted for pathological gambling.

    Lehr, William H.; Pupillo, Lorenzo Maria

    The Internet is now widely regarded as essential infrastructure for our global economy and society. It is in our homes and businesses. We use it to communicate and socialize, for research, and as a platform for E-commerce. In the late 1990s, much was predicted about what the Internet has become at present; but now, we have actual experience living with the Internet as a critical component of our everyday lives. Although the Internet has already had profound effects, there is much we have yet to realize. The present volume represents a third installment in a collaborative effort to highlight the all-encompassing, multidisciplinary implications of the Internet for public policy. The first installment was conceived in 1998, when we initiated plans to organize an international conference among academic, industry, and government officials to discuss the growing policy agenda posed by the Internet. The conference was hosted by the European Commission in Brussels in 1999 and brought together a diverse mix of perspectives on what the pressing policy issues would be confronting the Internet. All of the concerns identified remain with us today, including how to address the Digital Divide, how to modify intellectual property laws to accommodate the new realities of the Internet, what to do about Internet governance and name-space management, and how to evolve broadcast and telecommunications regulatory frameworks for a converged world.

    Background Telecommunication is limited or even impossible for more than one-thirds of all cochlear implant (CI) users. Objective We sought therefore to study the impact of voice quality on speech perception with voice over Internet protocol (VoIP) under real and adverse network conditions. Methods Telephone speech perception was assessed in 19 CI users (15-69 years, average 42 years), using the German HSM (Hochmair-Schulz-Moser) sentence test comparing Skype and conventional telephone (public switched telephone networks, PSTN) transmission using a personal computer (PC) and a digital enhanced cordless telecommunications (DECT) telephone dual device. Five different Internet transmission quality modes and four accessories (PC speakers, headphones, 3.5 mm jack audio cable, and induction loop) were compared. As a secondary outcome, the subjective perceived voice quality was assessed using the mean opinion score (MOS). Results Speech telephone perception was significantly better (median 91.6%, P 15%) were not superior to conventional telephony. In addition, there were no significant differences between the tested accessories (P>.05) using a PC. Coupling a Skype DECT phone device with an audio cable to the CI, however, resulted in higher speech perception (median 65%) and subjective MOS scores (3.2) than using PSTN (median 7.5%, P<.001). Conclusions Skype calls significantly improve speech perception for CI users compared with conventional telephony under real network conditions. Listening accessories do not further improve listening experience. Current Skype DECT telephone devices do not fully offer technical advantages in voice quality. PMID:28438727

    Delays in testing HIV-exposed infants and obtaining results in resource-limited settings contribute to delays for initiating antiretroviral therapy (ART) in infants. To overcome this challenge, Rwanda expanded its national mobile and Internet-based HIV/AIDS informatics system, called TRACnet, to include HIV polymerase chain reaction (PCR) results in 2010. This study was performed to evaluate the impact of TRACnet technology on the time to delivery of test results and the subsequent initiation of ART in HIV-infected infants. A retrospective cohort study was conducted on 380 infants who initiated ART in 190 health facilities in Rwanda from March 2010 to June 2013. Program data collected by the TRACnet system were extracted and analyzed. Since the introduction of TRACnet for processing PCR results, the time to receive results has significantly decreased from a median of 144 days [interquartile range (IQR): 121-197 days] to 23 days (IQR: 17-43 days). The number of days between PCR sampling and health facility receipt of results decreased substantially from a median of 90 days (IQR: 83-158 days) to 5 days (IQR: 2-8 days). After receiving PCR results at a health facility, it takes a median of 44 days (IQR: 32-77 days) before ART initiation. Result turnaround time was significantly associated with time to initiating ART (P technology for communication of HIV PCR results, coupled with well-trained and skilled personnel, can reduce delays in communicating results to providers. Such reductions may improve timely ART initiation in resource-limited settings.

  4. Strategy and the Internet.

    Science.gov (United States)

    Porter, M E

    2001-03-01

    Many of the pioneers of Internet business, both dot-coms and established companies, have competed in ways that violate nearly every precept of good strategy. Rather than focus on profits, they have chased customers indiscriminately through discounting, channel incentives, and advertising. Rather than concentrate on delivering value that earns an attractive price from customers, they have pursued indirect revenues such as advertising and click-through fees. Rather than make trade-offs, they have rushed to offer every conceivable product or service. It did not have to be this way--and it does not have to be in the future. When it comes to reinforcing a distinctive strategy, Michael Porter argues, the Internet provides a better technological platform than previous generations of IT. Gaining competitive advantage does not require a radically new approach to business; it requires building on the proven principles of effective strategy. Porter argues that, contrary to recent thought, the Internet is not disruptive to most existing industries and established companies. It rarely nullifies important sources of competitive advantage in an industry; it often makes them even more valuable. And as all companies embrace Internet technology, the Internet itself will be neutralized as a source of advantage. Robust competitive advantages will arise instead from traditional strengths such as unique products, proprietary content, and distinctive physical activities. Internet technology may be able to fortify those advantages, but it is unlikely to supplant them. Porter debunks such Internet myths as first-mover advantage, the power of virtual companies, and the multiplying rewards of network effects. He disentangles the distorted signals from the marketplace, explains why the Internet complements rather than cannibalizes existing ways of doing business, and outlines strategic imperatives for dot-coms and traditional companies.

A self-administered survey, hosted on a dedicated website, was used as a data collection method and 1005 responses were received. It was found that the period of Internet usage significantly influenced the decision to purchase via the Internet. Another finding was that the period of Internet usage significantly influenced whether those shopping on the Internet searched for, or considered searching for, product and service information online prior to purchasing from non-Internet-based sellers.

  6. Internet printing

    The Internet is rapidly changing the traditional means of creation, distribution and retrieval of information. Today, information publishers leverage the capabilities provided by Internet technologies to rapidly communicate information to a much wider audience in unique customized ways. As a result, the volume of published content has been astronomically increasing. This, in addition to the ease of distribution afforded by the Internet has resulted in more and more documents being printed. This paper introduces several axes along which Internet printing may be examined and addresses some of the technological challenges that lay ahead. Some of these axes include: (1) submission--the use of the Internet protocols for selecting printers and submitting documents for print, (2) administration--the management and monitoring of printing engines and other print resources via Web pages, and (3) formats--printing document formats whose spectrum now includes HTML documents with simple text, layout-enhanced documents with Style Sheets, documents that contain audio, graphics and other active objects as well as the existing desktop and PDL formats. The format axis of the Internet Printing becomes even more exciting when one considers that the Web documents are inherently compound and the traversal into the various pieces may uncover various formats. The paper also examines some imaging specific issues that are paramount to Internet Printing. These include formats and structures for representing raster documents and images, compression, fonts rendering and color spaces.

    2007-07-01

    The Internet provides inexpensive, interesting and comfortable recreation, but sometimes users get hooked. Thus, the computer-internet addiction concept has been proposed as an explanation for uncontrollable and damaging use. Symptoms of addiction could be compared to other addictive behaviors such as pathological gambling, kleptomania, trichotillomania, sex addiction and pyromania. Although criteria to diagnose this addiction have been proposed, methods of assessing excessive computer-internet use are limited. Early diagnosis could help the patient that suffers from this addiction before developing additional psychiatric diagnoses. A review of the proposed etiologies in the literature is summarized, together with recommendations for physicians and mental health officials.

  14. Rethinking Lean Service

    Science.gov (United States)

    Seddon, John; O'Donovan, Brendan; Zokaei, Keivan

    Ever since Levitt's influential Harvard Business Review article 'Production-Line Approach to Service' was published in 1972, it has been common for services to be treated like production lines in both the academic literature and more widely in management practice. The belief that achieving economies of scale will reduce unit costs is a common feature of management decision-making. As technological advancement has produced ever more sophisticated IT and telephony, it has become increasingly easier for firms to standardise and off-shore services. The development of the 'lean' literature has only helped to emphasise the same underlying management assumptions: by managing cost and workers' activity, organisational performance is expected to improve. This chapter argues that through misinterpretation of the core paradigm 'lean' has become subsumed into the 'business as usual' of conventional service management. As a result, 'lean' has become synonymous with 'process efficiency' and the opportunity for significant performance improvement - as exemplified by Toyota - has been missed.

    Introduction The presentation of health institutions in the internet is highly variable concerning marketing features and medical information. We aimed to investigate the structure and the kind of information provided on the Web sites of all departments of pediatric surgery in Germany. Furthermore, we aimed to identify the degree to which these Web sites comply with internet marketing recommendations for generating business. Method The Web sites of all pediatric surgery units referred to as departments on the official Web site of the German Society of Pediatric Surgery (GSPS) were assessed. The search engine Google was used by entering the terms "pediatric surgery" and the name of the city. Besides general data eight content characteristics focusing on ranking, accessibility, use of social media, multilingual sites, navigation options, selected images, contact details, and medical information were evaluated according to published recommendations. Results A total of 85 departments of pediatric surgery were included. On Google search results 44 (52%) ranked number one and 34 (40%) of the department's homepages were accessible directly through the homepage link of the GSPS. A link to own digital and/or social media was offered on 11 (13%) homepages. Nine sites were multilingual. The most common navigation bar item was clinical services on 74 (87%) homepages. Overall, 76 (89%) departments presented their doctors and 17 (20%) presented other staff members with images of doctors on 53 (62%) and contact data access from the homepage on 68 (80%) Web sites. On 25 (29%) Web sites information on the medical conditions treated were presented, on 17 (20%) details of treating concepts, and on 4 (5%) numbers of patients with specific conditions treated in the own department per year. Conclusion We conclude that numerous of the investigated online presentations do not comply with recommended criteria for offering professional information for patients and for promoting

    The internet has recently grown from a fringe cultural phenomenon to a significant site of cultural production and transformation. Internet Culture maps this new domain of language, politics and identity, locating it within the histories of communication and the public sphere. Internet Culture offers a critical interrogation of the sustaining myths of the virtual world and of the implications of the current mass migration onto the electronic frontier. Among the topics discussed in Internet Culture are the virtual spaces and places created by the citizens of the Net and their claims to the hotly contested notion of "virtual community"; the virtual bodies that occupy such spaces; and the desires that animate these bodies. The contributors also examine the communication medium behind theworlds of the Net, analyzing the rhetorical conventions governing online discussion, literary antecedents,and potential pedagogical applications.

    Full Text Available The aim of this paper is to determine, based on theoretical and empirical research, whether and to what extent the application of the social responsibility concept in e-commerce and marketing affects the satisfaction and loyalty of customers opting for on-line purchase. The main task is to use the case of global on-line buying and selling of tourist services to test the null hypothesis on the existence of a statistically significant correlation between the concept of social responsibility and customer's satisfaction and loyalty. Empirical research was conducted on a sample of 409 respondents from selected countries: Serbia, Turkey, Egypt, Italy and Spain. Contingency coefficient and Pearson's correlation coefficient were used for the interpretation of the results and determination of the degree of correlation between these variables. The research results indicated a significant statistical correlation between the concept of social responsibility and customer's satisfaction and loyalty. These results served as a basis for proposed measures necessary for defining the model of social corporate social responsibility in e-commerce, which will be generally binding for all online advertisers. Suggestions for future research are provided in the paper.

    Internet peer support groups for depression are becoming popular and could be affected by an increasing number of social network services (SNSs). However, little is known about participant characteristics, social relationships in SNSs, and the reasons for usage. In addition, the effects of SNS participation on people with depression are rather unknown. The aim was to explore the potential benefits and harms of an SNS for depression based on a concurrent triangulation design of mixed methods strategy, including qualitative content analysis and social network analysis. A cross-sectional Internet survey of participants, which involved the collection of SNS log files and a questionnaire, was conducted in an SNS for people with self-reported depressive tendencies in Japan in 2007. Quantitative data, which included user demographics, depressive state, and assessment of the SNS (positive vs not positive), were statistically analyzed. Descriptive contents of responses to open-ended questions concerning advantages and disadvantages of SNS participation were analyzed using the inductive approach of qualitative content analysis. Contents were organized into codes, concepts, categories, and a storyline based on the grounded theory approach. Social relationships, derived from data of "friends," were analyzed using social network analysis, in which network measures and the extent of interpersonal association were calculated based on the social network theory. Each analysis and integration of results were performed through a concurrent triangulation design of mixed methods strategy. There were 105 participants. Median age was 36 years, and 51% (36/71) were male. There were 37 valid respondents; their number of friends and frequency of accessing the SNS were significantly higher than for invalid/nonrespondents (P = .008 and P = .003). Among respondents, 90% (28/31) were mildly, moderately, or severely depressed. Assessment of the SNS was performed by determining the access

    Internet technologies have made a rapid progress, bringing convenience to daily life. On the other hand, internet use disorder and internet addiction (IA) have become reportedly serious health and social problems. In 2013, internet gaming disorder criteria have been proposed in the section of Conditions for Further Study of DSM-5. Existing epidemiological studies by questionnaire methods have reported that the prevalence of IA ranges between 2.8% and 9.9% among youths in Japan. Attention deficit hyperactivity disorder (ADHD), sleeping disorders, depression, obsessive compulsive disorder, and phobic anxiety disorder are extremely common comorbid mental disorders with IA. Some psychotherapies (e.g., cognitive behavioral therapy, motivational interviewing) and medical treatments (e.g., antidepressant drugs, methylphenidate) for comorbid mental disorders as well as rehabilitation (e.g., treatment camp) are effective for IA remission. However, some serious cases of IA may be difficult to treat, and prevention is very important. In future, the prevention, rehabilitations and treatments for IA will be more required in Japan.

    Background Internet peer support groups for depression are becoming popular and could be affected by an increasing number of social network services (SNSs). However, little is known about participant characteristics, social relationships in SNSs, and the reasons for usage. In addition, the effects of SNS participation on people with depression are rather unknown. Objective The aim was to explore the potential benefits and harms of an SNS for depression based on a concurrent triangulation design of mixed methods strategy, including qualitative content analysis and social network analysis. Methods A cross-sectional Internet survey of participants, which involved the collection of SNS log files and a questionnaire, was conducted in an SNS for people with self-reported depressive tendencies in Japan in 2007. Quantitative data, which included user demographics, depressive state, and assessment of the SNS (positive vs not positive), were statistically analyzed. Descriptive contents of responses to open-ended questions concerning advantages and disadvantages of SNS participation were analyzed using the inductive approach of qualitative content analysis. Contents were organized into codes, concepts, categories, and a storyline based on the grounded theory approach. Social relationships, derived from data of “friends,” were analyzed using social network analysis, in which network measures and the extent of interpersonal association were calculated based on the social network theory. Each analysis and integration of results were performed through a concurrent triangulation design of mixed methods strategy. Results There were 105 participants. Median age was 36 years, and 51% (36/71) were male. There were 37 valid respondents; their number of friends and frequency of accessing the SNS were significantly higher than for invalid/nonrespondents (P = .008 and P = .003). Among respondents, 90% (28/31) were mildly, moderately, or severely depressed. Assessment of the SNS was

    Full Text Available Electronic banking services such as internet banking offer bank clients substantial benefits over traditional banking channels. Although internet banking has been around for many years, increasing the use of the service by bank clients remains a priority for many managers of internet banking services. To address this managerial concern, the study investigates the factors that contribute to the enhanced use of internet banking by bank clients. Based on a literature review, internet-banking factors that could influence bank clients’ actual use of internet banking were identified. Data were collected from 1 156 users of internet banking. The results of the study showed that two factors influence internet banking usage, namely internet banking facilitating conditions and internet banking risk beliefs. The more favourable internet banking facilitating conditions are perceived to be, the more likely bank clients are to increase their use of internet banking. On the other hand, the greater the perceived risks associated with internet banking, the less the chances are that clients will do their banking through the internet. On the basis of these results, recommendations are provided to enhance the use of internet banking.

    Modern society has presented an epic technology development in recent years, driven strongly by communications networks: from micro environments such as personal area networks passing by cell phone to the global Internet network. The communications established in real-time are increasingly, a necessary input. However, the growing demand for communications services and in particularly mobile phone, has meant that the environment is altered by the large number of signals generated by electromagnetic fields that transmit high volumes of energy, which saturate the electromagnetic spectrum, these waves of energy called no ionizing energy. The World Health Organization, through the International Energy Agency Nonionizing (ICNIRP for its acronym in English), has conducted in recent years researches on the effects of the health of people exposed to nonionizing energy; also, have existed proposals regulating these exposure levels. Nonionizing electromagnetic fields are investigated, focusing on transmitting equipment for mobile phone systems in Costa Rica and electromagnetic safety criteria of exposure, both occupational as of general public. The electromagnetism basic concepts and parameters related with nonionizing radiations research are referenced, among them can be mentioned the relationship between the electric field E, the magnetic field H and the power density S. Other concepts such as near-field region, far-field region, exposure zones and specified absorption rate SAR, are also defined. A mathematical fundament is presented showing the relationships between the concepts explained.

By virtue of nearly complete electronic mediation, it is possible in principle to observe the time and ``spatial'' evolution of nearly all choices and interactions. This cyber-space therefore provides a view into a number of traditional research questions (from many academic disciplines) and creates its own new phenomena accessible for study. Despite its largely self-organized and dynamic nature, a number of robust quantitative regularities are found in the aggregate statistics of interesting and useful quantities. These regularities can be understood with the help of models that draw on ideas from statistical physics as well as other fields such as economics, psychology and decision theory. This thesis develops models that can account for regularities found in the statistics of Internet congestion and user surfing patterns and discusses some practical consequences. practical consequences.

    Full Text Available Este artigo analisa como a regulação do Serviço Móvel Pessoal (SMP, implementada pela Anatel em 2001, alterou a estrutura do mercado e as estratégias das operadoras do setor de telefonia móvel no Brasil, entre 2002 e 2007. Foi realizada uma pesquisa qualitativa e um estudo de caso múltiplo acerca das maiores operadoras do setor: Vivo, Tim, Claro e Oi. Diante da análise setorial e da influência de fatores externos sobre a estrutura do mercado, adotou-se o referencial teórico clássico de estratégia competitiva a fim de se entender as estratégias das operadoras. Adotou-se também um referencial mais específico do setor de telecomunicações, com destaque para trabalhos que discutem a convergência entre as telefonias fixa e móvel. Entre as conclusões do trabalho estão os efeitos de caráter deliberado das mudanças na regulação sobre as estratégias empresariais do setor, entre elas a adoção generalizada de estratégias de custo até o lançamento de serviços inovadores no mercado nacional, caracterizados pela integração entre as operadoras de telefonias fixa e móvel, promovendo estratégias de diferenciação, claramente representadas pela formação de dois grupos estratégicos: um com serviços convergentes do tipo bundle e relações de quase integração vertical entre operadoras fixas e móveis e outro com serviços convergentes entre operações de telefonia fixa e móvel verticalmente integradas.This article analyzes how PMS (Personal Mobile Service regulation made by Anatel in Brazil in 2001 changed the market structure and the operators' strategies for the telephony sector between 2002 and 2007.

  12. Poultry Internet

    Cheok, Adrian David

    Poultry are one of the most badly treated animals in the modern world. It has been shown that they have high levels of both cognition and feelings, and as a result there has been a recent trend of promoting poultry welfare. There is also a tradition of keeping poultry as pets in some parts of the world. However, in modern cities and societies, it is often difficult to maintain contact with pets, particularly for office workers. We propose and describe a novel cybernetics system to use mobile and Internet technology to improve human-pet interaction. It can also be used for people who are allergic to touching animals and thus cannot stroke them directly. This interaction encompasses both visualization and tactile sensation of real objects.

    Caballero, Rafael; Argyle, R. W.

    Amateur astronomers can carry out scientific research in many different ways. Some activities require expensive telescopes, cameras, and often access to dark skies. But those who live in highly polluted areas, or do not have access to very specialized equipment, still have many possibilities; amongst which is using the online resources available from the internet. In this chapter we explore Aladin, Simbad, and VizieR, three resources created and maintained by the Centre de Données astronomiques de Strasbourg (CDS). Although these applications are intended for professional astronomers, they are also freely available for amateurs. They allow us to find and measure old neglected difficult pairs, discover new double stars, and in general have a better understanding of those tiny pairs of points of light that we love to observe, photograph and measure.

    Background User involvement in the development of health care services is important for the viability, usability, and effectiveness of services. This study reports on the second step of the co-design process. Objective The aim was to explore the significant challenges in advancing the co-design process during the requirements specification phase of a mobile Internet service for the self-management of physical activity (PA) in rheumatoid arthritis (RA). Methods A participatory action research design was used to involve lead users and stakeholders as co-designers. Lead users (n=5), a clinical physiotherapist (n=1), researchers (n=2) with knowledge in PA in RA and behavioral learning theories, an eHealth strategist (n=1), and an officer from the patient organization (n=1) collaborated in 4 workshops. Data-collection methods included video recordings and naturalistic observations. Results The inductive qualitative video-based analysis resulted in 1 overarching theme, merging perspectives, and 2 subthemes reflecting different aspects of merging: (1) finding a common starting point and (2) deciding on design solutions. Seven categories illustrated the specific challenges: reaching shared understanding of goals, clarifying and handling the complexity of participants’ roles, clarifying terminology related to system development, establishing the rationale for features, negotiating features, transforming ideas into concrete features, and participants’ alignment with the agreed goal and task. Conclusions Co-designing the system requirements of a mobile Internet service including multiple stakeholders was a complex and extensive collaborative decision-making process. Considering, valuing, counterbalancing, and integrating different perspectives into agreements and solutions (ie, the merging of participants’ perspectives) were crucial for moving the process forward and were considered the core challenges of co-design. Further research is needed to replicate the results

    Full Text Available Internet Banking developed due to increasing demand of online banking transactions. The biggest advantages of Internet Banking consist of complex banking solutions, 24 hours availability, quick and secure access to the back-end application through Internet. These advantages are due to the use of SOA (service-oriented architecture. SOA appeared as a necessity of companies to integrate big and independent portions of applications, in order to obtain an homogeneous functionality of the system. For the Internet Banking applications, SOA proved to be the optimal architectural solution, for a smoth integration between banking services from the front-end to the back-end.This paper intend to offer an insite analyse of the Internet Banking applications architecture integrated with other banking systems. A SOA oriented analyse will establish the scope of the integration architecture.

    Problematic Internet addiction or excessive Internet use is characterized by excessive or poorly controlled preoccupations, urges, or behaviors regarding computer use and Internet access that lead to impairment or distress. Currently, there is no recognition of internet addiction within the spectrum of addictive disorders and, therefore, no corresponding diagnosis. It has, however, been proposed for inclusion in the next version of the Diagnostic and Statistical Manual of Mental Disorder (DSM). To review the literature on Internet addiction over the topics of diagnosis, phenomenology, epidemiology, and treatment. Review of published literature between 2000-2009 in Medline and PubMed using the term "internet addiction. Surveys in the United States and Europe have indicated prevalence rate between 1.5% and 8.2%, although the diagnostic criteria and assessment questionnaires used for diagnosis vary between countries. Cross-sectional studies on samples of patients report high comorbidity of Internet addiction with psychiatric disorders, especially affective disorders (including depression), anxiety disorders (generalized anxiety disorder, social anxiety disorder), and attention deficit hyperactivity disorder (ADHD). Several factors are predictive of problematic Internet use, including personality traits, parenting and familial factors, alcohol use, and social anxiety. Although Internet-addicted individuals have difficulty suppressing their excessive online behaviors in real life, little is known about the patho-physiological and cognitive mechanisms responsible for Internet addiction. Due to the lack of methodologically adequate research, it is currently impossible to recommend any evidence-based treatment of Internet addiction.

The new Inter-University project is rapidly evolving into a powerful consortium. 181 universities, 60 American companies and a few dozen international institutions are collaborating to create the communications technologies of the future. Their main focus is to rid themselves of the terrible congestion that exemplifies the Internet and create a new fast multimedia connection between research institutions. They promise that all this will be done far from the intrusion of the private market, a market that, according to the four fathers of Internet 2, "stifles creativity".The foundations of Internet 2 are comprised of two main technological notions. The first is the Gigapop, which is a regional network's interconnection point to the new Internet 2 cutting edge services. Some types of Gigapops are being constructed so that Internet 2 members can connect solely to Internet 2 services, while other Gigapops are being constructed to connect non Internet 2 members to various other services, such as the old Internet (a.k.a. the commodity Internet or Internet 1.The second technological notion is QoS, which stands for Quality of Services and is a new method of sending information around more efficiently. The basis of QoS is to create priorities for the information sent. In this way crucial medical information will have priority when compared to chess game simulations.The implementation of these two notions, together with other innovative technologies, requires a vast amount of funding, which is partly private but mainly governmental.

    Directory of Open Access Journals (Sweden)

    Diane Poulin

    2012-06-01

    Full Text Available Building on the analogy of data packets within the Digital Internet, the Physical Internet is a concept that dramatically transforms how physical objects are designed, manufactured, and distributed. This approach is open, efficient, and sustainable beyond traditional proprietary logistical solutions, which are often plagued by inefficiencies. The Physical Internet redefines supply chain configurations, business models, and value-creation patterns. Firms are bound to be less dependent on operational scale and scope trade-offs because they will be in a position to offer novel hybrid products and services that would otherwise destroy value. Finally, logistical chains become flexible and reconfigurable in real time, thus becoming better in tune with firm strategic choices. This article focuses on the potential impact of the Physical Internet on business model innovation, both from the perspectives of Physical-Internet enabled and enabling business models.

From the aspect of demand, stigma or the community perception that the internet is not important makes the people don't have internet access. The barriers is predominantly lack of knowledge in internet usage. This factor also causes community internet broadband literacy at level 0. As solutions, the preparation and establishment of policies and regulations such as the QoS service, interconnection, infrastructure sharing can provide high-quality internet broadband internet at a cheaper price. Besides the distribution of valuable mobile device (smartphone should also be encouraged by the application of local content level for the production of the device. No less important is the increase of community lietracy in internet broadband through socialization or training, both formal and informal.

    The Internet may provide an alternative option for rural lung cancer patients who lack access to on-site cancer support; however, Internet access and use among rural patients is unknown. An anonymous waiting-room survey was administered to all outpatient cardiothoracic surgery patients over 3 mo. Survey questions included age, gender, and diagnosis, possession of a home computer and Internet service, estimated Internet use, and use of the Internet for health information. Patients with known or suspected lung cancer were asked to indicate their interest in on-site and Internet cancer support. There were 597 returned surveys (response rate 96%). The mean age was 64.6 y (SE 0.55), and 58% were men. Diagnoses included known or possible lung cancer (15.4%), lung disease (9.5%), heart disease (30.4%), other diagnoses (13.9%), and undetermined (30.6%). There were 343 patients (57.4%) with a home computer and 299 (50.1%) with home Internet service. Average Internet use was 8.5 h per wk (n = 298), and 225 patients used the Internet for health information. Of the 92 patients with lung cancer, 10 indicated interest in on-site support services while 37 expressed interest in Internet-based support. Based on survey results, a slight majority of rural patients have a home computer and Internet access. Internet use for health information appears relatively common. Overall interest for support services among lung cancer patients appears modest with a greater interest in Internet-based services compared with on-site support. Copyright 2010 Elsevier Inc.

    The Internet hospital, an innovative approach to providing health care, is rapidly developing in China because it has the potential to provide widely accessible outpatient service delivery via Internet technologies. To date, China's Internet hospitals have not been systematically investigated. The aim of this study was to describe the characteristics of China's Internet hospitals, and to assess their health service capacity. We searched Baidu, the popular Chinese search engine, to identify Internet hospitals, using search terms such as "Internet hospital," "web hospital," or "cloud hospital." All Internet hospitals in mainland China were eligible for inclusion if they were officially registered. Our search was carried out until March 31, 2017. We identified 68 Internet hospitals, of which 43 have been put into use and 25 were under construction. Of the 43 established Internet hospitals, 13 (30%) were in the hospital informatization stage, 24 (56%) were in the Web ward stage, and 6 (14%) were in full Internet hospital stage. Patients accessed outpatient service delivery via website (74%, 32/43), app (42%, 18/43), or offline medical consultation facility (37%, 16/43) from the Internet hospital. Furthermore, 25 (58%) of the Internet hospitals asked doctors to deliver health services at a specific Web clinic, whereas 18 (42%) did not. The consulting methods included video chat (60%, 26/43), telephone (19%, 8/43), and graphic message (28%, 12/43); 13 (30%) Internet hospitals cannot be consulted online any more. Only 6 Internet hospitals were included in the coverage of health insurance. The median number of doctors available online was zero (interquartile range [IQR] 0 to 5; max 16,492). The median consultation fee per time was ¥20 (approximately US $2.90, IQR ¥0 to ¥200). Internet hospitals provide convenient outpatient service delivery. However, many of the Internet hospitals are not yet mature and are faced with various issues such as online doctor scarcity and

  20. Data forwarding mechanism for supporting real-time services during relocations in UMTS systems

    To minimize the interruption during the handovers or relocations invoked by subscribers moving is a very critical factor to enhance the performance of the UMTS systems. We know that the 2G systems have been optimized to minimize the interruption of speech during handovers by two main technologies: one is the bi-casting for the DL traffic and the other is the fast radio resynchronization by the UE for the UL traffic. In the UMTS systems, we have also implemented lossless relocations for non real-time services with high reliability by data buffering in the source RNC and target RNC for the UE. However, the UMTS systems support four QoS classes traffic flow: conversational class, streaming class, interactive class and background class. The main distinguishing factor between these QoS classes is how delay sensitive the traffic is: Conversational and Streaming classes are mainly used to carry real-time traffic flows, like video telephony, interactive and background classes are mainly used by traditional Internet applications like WWW, E-mail and FTP. It"s essential to provide the solutions for supporting real-time services to meet the requirement for QoS in UMTS systems. Apparently, the Data buffering mechanism is not adapted to real-time services because of it"s delay may exceed the basic requirement for real-time services. Under this background, the paper discussed two data forwarding solutions for real-time services from the PS domain in the UMTS systems: packet duplication and Core Network bi-casting. The former mechanism does not require any new procedures, messages nor information elements. The later mechanism requires that the GGSN or SGSN is able to bi-cast the DL traffic to the target RNC according to the relocations involving two SGSNs or just involving one SGSN. It also implicitly shows that we need change procedures at the nodes SGSN, GGSN and RNC which are involved in the relocation procedure based on existing procedures that we have already designed if
