Abstract:

BackgroundTelecommunications plays a critical enabling role in disaster response, both for the local population and for responses of external origin. However, it is common for telecommunications capacity to be reduced or disabled by the disaster or emergency. Meanwhile, the disaster stimulates demand for any remaining capacity, often resulting in total loss of telecommunications capability during the acute phase of a disaster and its response.Discussion and ObservationsThe Serval Project is addressing this through the implementation of a mesh mobile telephony system that is compatible with some existing mobile telephone handsets, and can be integrated into many more models without changing handset hardware designs or cost. This technology allows mobile telephones to directly communicate with one another, and allows telephone calls to be made without infrastructure beyond the telephones themselves. Our Distributed Numbering Architecture allows the telephones to use their existing telephone numbers, so that communications can continue immediately and without impediment when needed. The telephones self-organise, and relay calls for distant telephones, thus forming their own resilient telecommunications infrastructure that is able to remain operative during all phases of a disaster and its response, thus addressing an important vulnerability of the existing infrastructure-oriented approach to telecommunications. We see applications that include supporting communities in maintaining communication in order that medical and public health effects of emergencies can be responded to more effectively and potentially providing ready access to communications for distributed teams of emergency health and humanitarian workers in disasters. Our goal in creating this technology and removing all barriers to adoption is to facilitate its ubiquitous inclusion in new mobile telephones, so that we can leverage the mass production of consumer electronics to create a resilient telecommunications capacity that can be deployed anywhere without supporting infrastructure. This would enable the creation of, for example, networks consisting solely of used telephones.

Abstract:

Along with the development of the era, analog telephones have been replaced by IP Phones whose communication range can be wider and more flexible. Therefore, analog telephones are almost forgotten because of the limited communication range. With the addition of ITG (Internet Telephony Gateway) then analog telephones can communicate in VoIP networks. This research will discuss the analysis of voice quality in the communication process between telephone sets via ITG in a VoIP network based on the shape of the input and output, the amplitude response to frequency changes and the delay. Data retrieval is done by using a transmission test set as a substitute for human voice and knowing the amplitude value generated every time there is a change in frequency and an oscilloscope as a tool to determine the shape of the input and output waves as well as the delay. The results of this study indicate that delay generated by communication between analog telephones is <1 ms. When viewed from the form of the information signal generated from communication between telephone sets, that is, the shape of the input and output information signals are both sines, so it can be said that the information signal has not decreased in quality. The amplitude response resulting from frequency changes in communication between analog telephones is, the greater the value of the communication frequency.

Abstract:

ObjectiveTo record how breast screening centres in England deliver all biopsy results (cancer/non-cancer) from the breast assessment visit.DesignOnline survey of 63 of 79 breast screening centres in England from all regions (East Midlands, East of England, London, North East Yorkshire & Humber, North West, South East, South West, West Midlands). The survey contained quantitative measures of frequency for telephoning biopsy results (routinely, occasionally or never) and optional qualitative free-text responses. Surveys were completed by a staff member from each centre.ResultsThere were no regional trends in the use of telephone results services, (X² (14, n=63)=11.55, p=0.64), Centres who telephoned results routinely did not deliver results sooner than centres who deliver results in-person (X² (16, n=63)=12.76, p=0.69).When delivering cancer results, 76.2% of centres never telephone results and 23.8% of centres occasionally telephone results. No centres reported delivering cancer results routinely by telephone. Qualitative content analysis suggests that cancer results are only telephoned at the patient request and under exceptional circumstances.When delivering non-cancer results, 12.7% of centres never telephoned results, 38.1% occasionally telephoned results and 49.2% routinely telephoned results. Qualitative content analysis revealed different processes for delivering telephone results, including patient choice and scheduling an in-person results appointment for all women attending breast assessment, then ringing non-cancer results unexpectedly ahead of this prebooked appointment.ConclusionsIn the National Health Service Breast Screening Programme, breast assessment results that are cancer are routinely delivered in-person. However, non-cancer breast assessment results are often routinely delivered by telephone, despite breast screening policy recommendations. More research is needed to understand the impact of telephoning results on women attending breast assessment, particularly women who receive a non-cancer result. Future research should also consider how women themselves might prefer to receive their results.

Abstract:

Within a mere hundred years from the appearance of the first telephone in Zagreb in 1881 until the establishment of the first electronic telephone exchange in 1981, telephony in Zagreb went through several formative periods to assert itself. Zagreb was transformed from a provincial town in the Austrian-Hungarian Monarchy to the economic and cultural centre of Croatia. In that period, due to technological development, many changes took place that influenced the accessibility and price of the most popular telecommunications technology in the 20th century. At first a status symbol reserved for the wealthiest citizens, telephone gradually became accessible to all inhabitants of the city. In the decades after World War II, the new telephone infrastructure was constructed under the unfavourable conditions of technological underdevelopment, scarcity of professionals, and meagre financial resources. Nevertheless, despite all the aggravating circumstances, telephony managed to become an inevitable part of Zagreb’s everyday life. Modern telecommunications rest on these very steps that fixed telephony took in its development, and are therefore an indicator of the technological as well as cultural development of Zagreb.

Abstract:

This article examines the telephone’s entangled history within contemporary infrastructural systems of ‘big data’, identity and, ultimately, surveillance. It explores the use of telephone numbers, keypads and wires to offer new perspective on the imbrication of telephonic information, interface and infrastructure within contemporary surveillance regimes. The article explores telephone exchanges as arbiters of cultural identities, keypads as the foundation of digital transactions and wireline networks as enacting the transformation of citizens and consumers into digital subjects ripe for commodification and surveillance. Ultimately, this article argues that telephone history – specifically the histories of telephone numbers and keypads as well as infrastructure and policy in the United States – continues to inform contemporary practices of social and economic exchange as they relate to consumer identity, as well as to current discourses about surveillance and privacy in a digital age. This article is based on a paper presented at the Media in Transition symposium (Utrecht, June 28, 2018), in the Industries and Infrastructures panel organised by Judith Keilbach.

Abstract:

As people age, they face motor, sensory, and cognitive decline that may compromise their performance of activities of daily living and instrumental activities of daily living. Telephone use is an important instrumental activity of daily living for older adults, but many have difficulty in making and receiving calls. Today, there are many features that can be added to the telephone that can help compensate for impairments, but often these features are not used. To better understand the problems of older adults in using their telephones, we surveyed 609 older adults living in the community who had chronic health conditions. Interviews were conducted face-to-face, by telephone, or by mail. The most common reasons for not using more telephone special features were cost, lack of perceived need, and lack of knowledge of the features. Occupational therapists who work with older adults must understand the importance of telephones in their lives and offer them information and assistance in finding telephones with features that match their special needs. The findings of this study suggest that a significant number of older adults with chronic health conditions are unaware of low-cost, feature-laden telephones that could make their communications easier or, for some, possible.

Abstract:

The 25th of October 1985, France numbering telephone plan was transformed from seventy telephone zones to two in just one night. The computerisation of France was highly promoted but the Telephone network was quickly running out of numbers. We analyse this overnight event as an infrastructural event and the biggest update in telephone history. It market a crucial step in the direction of network as a service, turning telephones into terminal while network fade in the background. By doing so, we insist on the historical specificity of what was a technocratic event, an innovation process with a highly closed script.

Abstract:

ASEAN-China Free Trade Area (ACFTA) is an agreement with ASEAN countries with China to establish a free trade area. Telephones are the main commodity in China which is included in the largest import category in ASEAN, where the value of imports of cellphones from China is higher than other countries, China dominates the import of cellphones in ASEAN with 55% o ea (ACFTA) on telephone imports from ASEAN countries in China. This study uses annual data from 2006 to 2020f total imports from other countries. This study aims to analyze the influence of the ASEAN-China Free Trade Ar. The methods used in this research are descriptive analysis and gravity model. Quantitatively, it shows that the production of telephones in each ASEAN country has not met the demand for telephones, so imports are carried out. The estimation results of the gravity model show that the ACFTA variable has no significant effect on China's telephone imports to ASEAN. Other factors that affect China's telephone imports to ASEAN are ASEAN's real GDP, China's real GDP, real exchange rate, distance and inflation affect China's telephone imports to ASEAN.

Abstract:

A low-cost, general-purpose telemetry system was developed for use in rural health centres, hospitals, ambulances and clinics. It was designed to transmit a range of analogue biomedical signals using various communications media. The system was tested using different telephone systems, including mobile telephony. The results showed a maximum sample rate of 1.6 kHz using the public telephone network. W h three data channels the system produced sample rates of 500 Hz at 8 bit/sample. Typical overall delay times were below 100 ms. Mobile tests showed that the GSM telephone was superior to the Nordic mobile telephone (NMT 900). In field tests, sample rates of 990 Hz were obtained using GSM telephony. Bit error rates were less than 10-7 for all applications and high-fidelity regeneration was obtained at the receiver. The tests showed that the system was well suited for telemetry of analogue biomedical signals in a broad range of telemedicine applications.

Abstract:

PBX is a telephone communication connection device that is commonly used in buildings that require a telephone connection. However, some PBX products cannot be directly connected to analog telephones, so they require a module called an S2 module. S2 module can converts the port on the PBX to an FXS port that can be connected to an analog phone. Apart from PBX, there is ITG which can be used as telephone line communication. However, ITG already has an FXS port so it does not require additional modules. In Indonesia, there are standard provisions for the use of analog telephone communication devices which have been regulated in SNI for analog telephones. This research examines analog telephone communication devices according to SNI in Indonesia. The results of this test show the TA400 and MyPBX Standard at the impedance value when the on-hook state gets an average value of 64 K?, when the off-hook condition averages a value of 343 ?, the AC voltage test when the call comes on average gets a value of 343 ?. a value of 60 VAC, which means that it meets the SNI standard.

Abstract:

From the 1881 incorporation of Los Angeles' first telephone company, telecommunications spread rapidly in the city and its surrounding region. This article details the proliferation of telephony, and its role in the region's rapid growth and in the formation of region-wide economic networks. Conversely, Pomona, 30 miles from Los Angeles, serves as an example of how local telephone systems could also facilitate sub-regional economic blocs. The history of the telephone, this article argues, is essential to understanding the L.A. region's multi-nucleated development and its economic structure.

Abstract:

Playback is an important method of surveying animals, assessing habitats and studying animal communication. However, conventional playback methods require on-site observers and therefore become labour-intensive when covering large areas. Such limitations could be circumvented by the use of cellular telephony, a ubiquitous technology with increasing biological applications. In addressing concerns about the low audio quality of cellular telephones, this paper presents experimental data to show that owls of two species ( Strix varia and Megascops asio ) respond similarly to calls played through cellular telephones as to calls played through conventional playback technology. In addition, the telephone audio recordings are of sufficient quality to detect most of the two owl species' responses. These findings are a first important step towards large-scale applications where networks of cellular phones conduct real-time monitoring tasks.

Abstract:

The rapid diffusion of mobile telephony is an important subject in diffusion studies of innovation. This study attempts to learn how mobile telephony diffuses in China, which has the most mobile telephone subscribers worldwide, in terms of the appropriate growth model and forces driving the diffusion. To identify the appropriate growth model, this study compares the fitness and forecasting ability of three conventional models — the Logistic, Bass, and Gompertz models. The determinants of the diffusion rate are then analyzed based on the most appropriate model. Empirical results, based on data for mobile telephone subscribers in China for 1986–2007, indicate that the Gompertz model performs best. Moreover, the four determinants for the diffusion rate are: number of fixed-line telephone subscribers, the low cost of mobile handsets, pre-paid service and the personal handy-phone system (PHS) service.

Abstract:

The increasing cost and decreasing coverage of Random Digit Dialing (RDD) landline telephone surveys motivated The Surveys of Consumer Attitudes (SCA) at the University of Michigan to conduct monthly experimental mail survey studies using address-based sampling (ABS). The primary objectives of the experimental studies were to evaluate the feasibility of transitioning the data collection operations from telephone to mail and to investigate differential survey errors between the two modes. Overall mail survey response rates were comparable to the RDD landline survey. Coverage improved using ABS, with more than 20% of the mail responses from non-landline telephone households not covered by the RDD landline telephone surveys. Mail survey respondents from households without landline telephones were more likely to be younger, have lower income, be renters and live in one-person households. There were no apparent measurement or reporting differences between the telephone and mail self-administered modes of data collection. Furthermore, inclusion of non-landline telephone households did not result in any substantial demographic or economic attitude differences between the two approaches.

Abstract:

Cellular Telephone is a communication tool that can connect people with others who are obstructed by distance and time. Its use is now a priority for most people. The level of traffic accidents caused by drivers who drive their vehicles while using the telephone is also increasing. In connection with the above it will be discussed regarding the regulation of the use of cellular telephone while driving as well as law enforcement for motorists who violate the use of cellular telephone while driving. In this paper the method used is a normative legal method which uses legal material collection techniques in the form of study documents and uses primary legal material sources such as legislation and secondary legal materials such as legal books which are then poured descriptively to get final conclusions. Then regarding the conclusions of the results of this study namely violations of the use of cellular telephones have explained that in driving there is no concentration to cause an accident and even to cause death then threatened with imprisonment and fines as regulated in Law No. 22 of 2009 concerning Past Road Traffic and Transportation. For law enforcement efforts to prevent the use of cellular telephones it is necessary to understand the community from adolescents to adults of the dangers and impacts of using cellular telephones when driving. So that safety can be created in driving with other public road users.

Abstract:

In this paper, we proposed a protocol to convert 2W telephone analog signals to Ethernet data in a private PSTN 2W tactical voice system. There are several kinds of operational problems in the tactical telephone network where 2W telephone copper lines are installed hundreds of meters away from the PBX in a headquarter site. The reason is that it is difficult to install and maintain the 2W telephone copper cable in severe operational fields and to meet safety and stability operational requirements of the telephone line under lighting and electromagnetic environments. In order to solve these challenging demands, we proposed an efficient method that the 2W analog interface signals between a private PBX system and a 2W telephone is converted to Ethernet messages using the optical Ethernet data communication network already deployed in the tactical weapon system. Thus, it is not necessary to install an additional optic cable for the ethernet telephone line and to maintain the private PSTN 2W telephone network. Also it provides safe and secure telecommunication operation under lightning and electromagnetic environments.<br/>This paper presents the conversion protocol from 2W telephone signals over Ethernet interface between PBX systems and 2W telephones, the mutual exchange protocol of ethernet messages between two converters, and the rule to process analog signal interface. Finally, we demonstrate that the proposed technique can provide a feasible solution in the tactical weapon system by analyzing its performance and experimental results such as the bandwidth of 2W telephone ethernet network and the transmission latency of voice signal, and the stability of optic ethernet voice network along with the ethernet data network.

Abstract:

Background Telephone consultations between physicians provide quick access to medical advice, allowing patients to be cared for by calling physicians in their local settings. Objective As part of a quality assurance study of a physician-to-physician consultation program in Alberta, Canada, this environmental scan aims to identify the characteristics and outcomes of physician-to-physician telephone consultation programs across several countries. Methods We searched 7 databases to identify English publications in 2007-2017 describing physician-to-physician consultations using telephones as the main technology. To identify Canadian programs, the literature search was supplemented with an additional internet search. Results The literature search yielded 2336 citations, of which 17 publications were included. Across 7 countries, 14 telephone consultation programs provided primary care providers with access to various specialists through hotlines, paging systems, or call centers. The programs reported on the avoidance of hospitalizations, emergency department visits and specialty visits, caller satisfaction with the telephone consultation, and cost avoidance. Conclusions Telephone consultation programs between health care providers have facilitated access to specialist care and prevented acute care use.

But despite the multiple telephones that echo in and across Jacques Derrida's work, and specifically his writing to and with Hélène Cixous, it is only since Derrida's death that critical interest in the phone has fully emerged, with work by Royle (2006) , Prenowitz (2008) , Bennington (2013) and Turner (2014) stressing the value of staying on the line. Engaging with Derrida, however, is not simply a matter of picking up the receiver. For the telephone is also, Derrida insists in H.C. for Life (2006), a ‘poetico-technical invention’, that is, the telephone is ‘thought itself’. This paper is about how the telephone ‘thinks’ Derrida, about how it remembers Derrida, and about how it offers us a line for re-imagining his voice. Bound up with the uncanny mechanisms of the telephone, it invites readers to participate in long-distance calling – listening across species, texts and worlds.

Abstract:

Objective. To objectively study mobile and standard landline telephone speech perception performance using cochlear implant recipients. Study Design. Nonrandomized trial. Setting. Tertiary referral center. Subjects and Methods. Twenty-five subjects enrolled in this study from a pool of 50 cochlear implant recipients who had participated in an earlier questionnaire study from which demographic data were gathered. Preoperative speech perception scores were collated from preoperative audiological data. Postoperative speech perception scores were calculated with subjects listening to the Australian Version of the Bamford-Kowal-Bench Sentence Test read aloud in a soundproof booth via live voice, played back on a speaker, on a standard landline and mobile phone. Telephone speech perception scores were analyzed and banded into 3 performance categories: very good (90%-100%), good (80%-89%), and fair (<80%). Results. The mean speech perception scores were 88.6% (SD, 14.3%) for postoperative recorded speech and 92.3% (SD, 10.7%) for live voice listening, which were significantly better than the mean score of 37.2% (SD, 29.1%) listening to recorded voice preoperatively. The mean speech perception score was 84.3% (SD, 20.7%) using a mobile telephone and 57% (SD, 29.4%) using the standard landline. Further analysis showed better performance with mobile phones over standard landlines. Seventy-six percent of subjects attained at least good telephone speech performance (score >80%). Older patients had poorer telephone speech perception than younger patients did. Conclusions. Many cochlear implant recipients achieve good objective telephone speech perception performance, indicating that they should be effective telephone users, especially when using mobile telephones and among younger implant recipients.

Abstract:

Recently, voice dispatching telephone is applied as one of information interactive by power grid dispatching in China, playing a significant role in the progress of power grid dispatching. However, with the increasing of grid scale, more and more information should be figured out by dispatchers. Conventional dispatching telephone in communication presents enormous challenge, thus, much effort should be made to solve this problem. In the article, the shortcomings of dispatching telephone in communication are systematically analyzed by the point of our actual country power grid dispatching. To remedy telephones shortcomings, text technology is introduced and a uniform dispatcher interactive platform is formed. This platform meets the requirements of interactive in power grid dispatching perfectly.

Abstract:

Hearing loss is an invisible but significant barrier in daily life, including telephone conversations. Internet Protocol Caption Telephone Services (IP CTS) is a telecommunications relay service for an individual who can speak, but who has difficulty hearing over the telephone. An individual can use a telephone and an IP-enabled device to listen to the other party and simultaneously read transcriptions of the other party’s words. This article presents the results from a usability assessment of IP CTS devices and alternative speech recognition technologies to provide qualitative and quantitative measures for device and caption performance. The results demonstrate that there is at least one automatic Speech-To-Text (STT) engine that is equivalent or better than three of the four currently available IP CTS devices at producing an accurate, expedient, and usable service.

Abstract:

Social isolation is an important determinant of elderly suicides (Shah and De, 1998). If elderly people have telephones then social isolation can be reduced as they can contact friends and relatives and vice versa. Also, the elderly can use the telephone to seek help from telephone helplines, general practitioners, social workers, psychiatric services and friends and relatives. Additionally, general practitioners, social workers, psychiatric services and friends and relatives can contact elderly people to check on them and support them. However, a major criticism of such interventions is that those determined to kill themselves are unlikely to use a helpline. There are several studies looking at the relationship between suicide and telephone help lines. These studies showed evidence that the helpline reduced suicidality during the course of the telephone consultation or immediately afterwards and reduced the number of re-attempted suicides (De Leo et al., 1995; Mishara and Daigle, 1997; Vaiva et al., 2006; Gould et al., 2007). A study of elderly participants reported an association between lower suicide rates and availability of a telephone help and telephone check service (De Leo et al., 1995). This service provided elderly people with home assistance by allowing them to call for help and to receive weekly assessments of needs and emotional support. However, there are only a limited number of studies in this area. Therefore, a cross-national study examining the relationship between elderly suicide rates and the prevalence of societal use of telephone was undertaken.

Abstract:

The ownership of mobile telephones is now almost universal amongst the teenage population of the United Kingdom. Such telephones are a potential source of electromagnetic interference to medical equipment. We describe a case of troublesome interference with an electrocardiogram recording in a teenage patient whose mobile telephone was left switched on during a visit to hospital. This is likely to be a common reason for poor quality electrocardiographic recordings.

Abstract:

Background Social distancing guidelines for COVID-19 have caused a rapid transition to telephone and video technologies for delivering treatment for substance use disorders (SUDs). Objective This study examined the adoption of these technologies across the SUD service continuum, acceptance of these technologies among service providers, and intent of providers to use these technologies after the pandemic. Additional analysis using the validated technology acceptance model (TAM) was performed to test the potential applications of these technologies after the pandemic. The study objectives were as follows: (1) to assess the use of telehealth (telephone and video technologies) for different SUD services during COVID-19 in May-June 2020, (2) to assess the intended applications of telehealth for SUD services beyond COVID-19, (3) to evaluate the perceived ease of use and value of telehealth for delivering SUD services, and (4) to assess organizational readiness for the sustained use of telehealth services. Methods An online survey on the use of telephonic and video services was distributed between May and August 2020 to measure the current use of these services, perceived organizational readiness to use these services, and the intent to use these services after COVID-19. In total, 8 of 10 regional Addiction Technology Transfer Centers representing 43 states distributed the survey. Individual organizations were the unit of analysis. Results In total, 457 organizations responded to the survey. Overall, the technology was widely used; >70% (n>335) of organizations reported using telephone or video platforms for most services. The odds of the intent of organizations to use these technologies to deliver services post COVID-19 were significantly greater for all but two services (ie, telephonic residential counseling and buprenorphine therapy; mean odds ratio 3.79, range 1.87-6.98). Clinical users preferred video technologies to telephone technologies for virtually all services. Readiness to use telephone and video technologies was high across numerous factors, though telephonic services were considered more accessible. Consistent with the TAM, perceived usefulness and ease of use influenced the intent to use both telephone and video technologies. Conclusions The overall perceived ease of use and usefulness of telephonic and video services suggest promising post–COVID-19 applications of these services. Survey participants consistently preferred video services to telephonic services; however, the availability of telephonic services to those lacking easy access to video technology is an important characteristic of these services. Future studies should review the acceptance of telehealth services and their comparative impact on SUD care outcomes.

Abstract:

Background: Computers and telephones are ubiquitous in the hospital and have been shown to be contaminated with potentially pathogenic microorganism. The aim of the study was to determine microbial contamination on computer keyboards and telephone handsets and the effectiveness of a disinfecting technique (DT). Methods: A matched cross-over study, involving an overall of 50 computer keyboards and 50 telephone handsets, was conducted in three hospitals, located in the Local Health Area of Siena (Italy) before and after the use of an innovative DT consisting of a malleable-elastic compound, containing ethanol, which adheres to surfaces, removes dirt and disinfects. Total bacterial count was evaluated and several types of bacteria and fungi were researched pre- and post- use of the DT. Non parametric tests: Wilcoxon signed rank and Mann Whitney, were used, when appropriate. Results: The DT was effective in disinfecting the objects. In fact, Colony-Forming Units (CFUs) decreased to zero in most comparisons. All the comparisons showed significant differences (p<0.001) after the DT, both for computer keyboards and telephone handsets. The only exception was found for molds in telephones (p=0.062). Keyboards emerged to be dirtier than telephones handsets (p<0.05) for several types of bacteria. Conclusions: The data suggest that microbial contamination of keyboards and telephones is considerable. These objects can be a vehicle for Health Care-Associated Infections HAIs and their disinfection should not be neglected. The DT showed to be appropriate for the disinfecting purpose.

Abstract:

Purpose The aims of this study are to review the literature examining the arguments for and against the telephonic qualitative research interviews, to develop criteria for assessing when the use of the telephone is suitable in qualitative research and if suitable to offer detailed strategies for the effective use of this data collection instrument. Design/methodology/approach The study is a thematic analysis of the literature, informed by the researchers’ experiences using the telephone, computer-based audio and face-to-face interviews for an accounting research project involving 50 semi-structured interviews with managers. Findings The study identifies five criteria to determine the suitability of using the telephone in qualitative research interviews. In addition, the study offers a set of detailed strategies on what to do before, during and after a telephonic qualitative research interview. Research limitations/implications The study can assist qualitative researchers in deciding when to use the telephone and how to use it effectively. Originality/value The study builds on the limited prior research and provides a more complete list of strategies on the effective use of the telephone in qualitative social sciences research. These strategies are a synthesis of existing studies and observations drawn from the author's study, which examines the work of organisational managers. In comparison, prior studies have been based on research projects that explored sensitive personal issues and emotive experiences not always related to managerial work.

Abstract:

The objective of this study was to evaluate the feasibility of using computer assisted telephone interviewing (CATI) as a method for obtaining information on reproductive health in Brazil. A total of 998 eligible women for the study were selected to answer a questionnaire through computer- assisted telephone interviewing undertaken by trained interviewers. The outcomes of each telephone contact attempt were described. Differences between groups were assessed using the χ2 test. Phone contact was made in 60.3% of the attempts and 57.5% of the interviews were completed. The success rate improved with the decrease in time from hospitalization to interview and with the higher numbers of telephones available. A total of 2,170 calls were made, comprising of one to sixteen attempts per woman. The majority of situations where extra calls were necessary were due to the number being busy or to the fact that the woman was not available at the time of the call. CATI can prove be a valuable procedure for obtaining information on reproductive health among Brazilian women, particularly for relatively recent events and when more than one alternative telephone number is available.

Abstract:

Communication through voice call leads to significant growth in technology in distant areas where two or more people from opposite ends of world will connect. This research describes a case study of voice call transfer service. This research aims at designing a system that will allow Android users to communicate over Wi-Fi. This design is able to transfer voice of incoming telephone caller over Wi-Fi network at real time through UDP. It uses client/server architecture: Server for receiving telephone call and transferring voice (one user) and client for receiving incoming caller voice and enables communication with server. Architecture designed could be used on Android smart phones with telephony enabled and tablets with telephony not enabled. Outcome of this research will allow users to communicate on real time at no cost. Proposed design gives cost effective, reliable and real time voice communication over Wi-Fi. It provides good and comfort experience to users in emergency situation where user cannot effort cost for telephone call. Proposed design is useful for educational organizations, construction buildings, shopping malls and hospitals which point to new possibilities for voice communication.

Abstract:

Any artefact – a hammer, a telescope, an artificial hip – may malfunction. Conceptually speaking, artefacts have an inherent normative aspect. I argue that the normativity of artefacts should be understood as part of reality, and not just “in our concepts.” I first set out Deflationary Views of artefacts, according to which there are no artefactual properties, just artefactual concepts. According to my contrasting view – the Constitution View – there are artefactual properties that things in the world really have. For example, there is a property of being a telephone per se; we apply our concept telephone to things that have that property. Things that have the property of being a telephone are constituted by, but not identical to, aggregates of particles. To be an artefact, an object must have an intended function, among other things. Telephones – in virtue of being the kind of objects that they are – are always subject to malfunction. And malfunctions, when they occur, are just as much part of the world as telephones are. The example of artefacts shows that what is in the world – what really exists – need not be “mind-independent” nor independent of our concepts.

Abstract:

INTRODUCTION Patients with minor anorectal conditions are frequently reviewed at an 8-week out-patient appointment (OPA). This study was designed to assess whether telephone follow-up could reduce OPA numbers whilst maintaining patient satisfaction. PATIENTS AND METHODS Over an 11-month period, 46 patients (23 male) underwent banding of haemorrhoids and 14 were prescribed medical treatment for fissure-in-ano (3 male). All were telephoned at 6 weeks and were offered an 8-week OPA if they had continuing problems. Patients were telephoned at a later date by a member of the hospital's patient panel to assess satisfaction. RESULTS Overall, 88% were contacted at 6 weeks, 60% at the first attempt; 40% required two or more attempts. Of those who underwent banding, 68% were asymptomatic, 17% requested an OPA for re-banding and 15% requested an OPA for a different problem. Of fissure patients, 25% were cured; the remainder were prescribed either second-line medical treatment (8%), anorectal physiology (42%) or surgery (25%). All avoided an OPA. Of a potential 60 OPAs, 47 were saved by telephone follow-up. None of 7 non-contactable patients accepted a written offer of an OPA. Overall, 89% of patients were contacted by the patient panel; of these patients, 93% reported a high level of satisfaction. CONCLUSIONS Telephone follow-up can reduce the number of OPAs following out-patient treatment of minor anorectal conditions whilst maintaining a high level of patient satisfaction. However, it requires considerable consultant time. This process could be developed into either a nurse-led service with booked telephone appointments or a patient-led service to a dedicated hotline.

Abstract:

The limited narrow band (LNB) speech signal spread in the range of 300 to 3400Hz used in public switched telephone networks results in poor-quality telephony speech. Bandwidth extension techniques are performed to expand the frequency range from LNB speech to a clear wideband (CWB) speech signal range of 50Hz-7000Hz over existing public telephone networks. In this paper, a novel robust speech bandwidth extension algorithm by Discrete Wavelet Transform- Discrete Cosine Transform- Based Data Hiding (DWT-DCT-DH) Hybrid transform model was used to spread the out-of-band (3400Hz to 7000Hz) speech frequencies over the LNB speech. In this proposed technique the out-of-band speech frequencies are embedded in LNB speech and imperceptibly spread over the network. These Embedded out-of-band speech frequencies are recovered steadily at the receiver end to generate a restored CWB telephony speech of considerably better quality. The proposed technique simulation results show more intelligible and better-quality telephony speech generated compared to the other bandwidth extension techniques.
