To assess the accessibility level of Internet appointment scheduling in primary care and the fulfilment of the requirements of Spanish legislation. Descriptive study of the accessibility of 18 web sites corresponding to the autonomic health services responsible for Internet appointment scheduling for primary health care services. The level of web accessibility was evaluated by means of five automated tools. Only six websites self-declared to be in compliance with level AA of WCAG 2.0. The level of web accessibility according to the legal requirements in Spain is low. The evaluation tools identified the main errors to be corrected. Most of the autonomic health services responsible for Internet appointment scheduling in primary care need to improve their level of web accessibility and ensure that it complies with Spanish legislation.

Patients are increasingly using the Internet (43% in 2000 vs. 70% in 2006) to obtain health information, but is there a difference in the ability of urban and suburban emergency department (ED) customers to access the Internet? To assess computer and Internet resources available to and used by people waiting to be seen in an urban ED and a suburban ED. Individuals waiting in the ED were asked survey questions covering demographics, type of insurance, access to a primary care provider, reason for their ED visit, computer access, and ability to access the Internet for health-related matters. There were 304 individuals who participated, 185 in the urban ED and 119 in the suburban ED. Urban subjects were more likely than suburban to be women, black, have low household income, and were less likely to have insurance. The groups were similar in regard to average age, education, and having a primary care physician. Suburban respondents were more likely to own a computer, but the majority in both groups had access to computers and the Internet. Their frequency of accessing the Internet was similar, as were their reasons for using it. Individuals from the urban ED were less willing to schedule appointments via the Internet but more willing to contact their health care provider via e-mail. The groups were equally willing to use the Internet to fill prescriptions and view laboratory results. Urban and suburban ED customers had similar access to the Internet. Both groups were willing to use the Internet to access personal health information. Copyright © 2012 Elsevier Inc. All rights reserved.

Speed control system for an access gate

An access control apparatus for an access gate. The access gate typically has a rotator that is configured to rotate around a rotator axis at a first variable speed in a forward direction. The access control apparatus may include a transmission that typically has an input element that is operatively connected to the rotator. The input element is generally configured to rotate at an input speed that is proportional to the first variable speed. The transmission typically also has an output element that has an output speed that is higher than the input speed. The input element and the outputmore » element may rotate around a common transmission axis. A retardation mechanism may be employed. The retardation mechanism is typically configured to rotate around a retardation mechanism axis. Generally the retardation mechanism is operatively connected to the output element of the transmission and is configured to retard motion of the access gate in the forward direction when the first variable speed is above a control-limit speed. In many embodiments the transmission axis and the retardation mechanism axis are substantially co-axial. Some embodiments include a freewheel/catch mechanism that has an input connection that is operatively connected to the rotator. The input connection may be configured to engage an output connection when the rotator is rotated at the first variable speed in a forward direction and configured for substantially unrestricted rotation when the rotator is rotated in a reverse direction opposite the forward direction. The input element of the transmission is typically operatively connected to the output connection of the freewheel/catch mechanism.« less

The "digital divide" is the gap between those with access to information tools such as the Internet and those without access. The gap has been described by income, education, age, and race. Little information exists on computer and Internet access and use for health information by parents, particularly among populations of low income and low education level. To describe computer and Internet access and use, including health information retrieval, among low-income, urban, African American caregivers (parents). Cross-sectional survey administered in pediatric waiting rooms of urban community-based health centers in a low-income area. Caregivers of pediatric outpatients. Access to computers, Internet access, and use of Internet for health information. In 2003, among 260 African Americans who completed surveys, 58% had a computer and 41% had home Internet access. Fifty-two percent had used the Internet for finding health information. Ninety-three percent agreed or strongly agreed that there is useful health information on the Internet. Ninety-two percent agreed or strongly agreed that they would want to talk with a medical professional about health information on the Internet. Sixty-five percent of respondents had no additional schooling after high school. Annual household income was Internet access were significantly higher in caregivers with higher education and income. Most pediatric patients' families have home computers and believe there is useful health information on the Internet, even among low-income and traditionally underserved populations. Most would like to discuss Internet-based health information with their providers.

How Much Is Too Much to Pay for Internet Access? A Behavioral Economic Analysis of Internet Use.

PubMed

Broadbent, Julie; Dakki, Michelle A

2015-08-01

The popularity of online recreational activities, such as social networking, has dramatically increased the amount of time spent on the Internet. Excessive or inappropriate use of the Internet can result in serious adverse consequences. The current study used a behavioral economic task to determine if the amount of time spent online by problematic and nonproblematic users can be modified by price. The Internet Purchase Task was used to determine how much time undergraduate students (N=233) would spend online at 13 different prices. Despite high demand for Internet access when access was free, time spent online by both problematic and nonproblematic users decreased dramatically, even at low prices. These results suggest that the amount of time spent online may be modified by having a tangible cost associated with use, whereas having free access to the Internet may encourage excessive, problematic use.

2008-04-01

An exploratory study to determine the proportion of people aged 50-76 years who have Internet access, the location of this access, predictive characteristics of such access, and preparedness to receive unsolicited health information through this medium. A random sample of 1,000 South Australians was identified from the Australian Electoral Commission roll and contacted by telephone in 2006. They were invited to answer questions about their access to the Internet and attitude towards receiving unsolicited health information via the Internet. Of those contacted, 41% provided information. Of this group, 59% indicated that they had Internet access, mostly at home. Men were more likely than women to have home access (p<0.05). Higher educational achievement, higher economic status and younger age were all significantly associated with access. Of those who had access, 65% would be willing to receive health information through the Internet. More than half the population older than 50 years has access to the Internet at some location, and there is a general acceptance of the possibility of receiving health-promoting material via this medium. However, delivery via the Internet alone would disadvantage those who are less educated, less financially well off and older. It is likely that a generational change in the entire nature of public communication will influence the efficiency and effectiveness of preventive health promotion delivery via the Internet. In order to facilitate improved health outcomes, issues of disparity of access must be addressed.

Can Internet Access Growth Help Reduce the Global Burden Of Noncommunicable Diseases?

PubMed Central

Kohler, Stefan

2013-01-01

Noncommunicable diseases, such as cardiovascular diseases, cancer, chronic respiratory diseases, and diabetes, are currently the leading causes of death in several regions of the world. The continuing fast increase in the global burden of noncommunicable diseases is accompanied by a speedy worldwide internet access growth. The worldwide number of internet users has doubled over the past five years. As the internet can make the access to information on a healthy lifestyle and disease prevention activities easier, internet access growth may help to promote good health. Against this background, I discuss the roles the internet and access to information can play in health promotion. I also present an open access web portal on local prevention and health promotion activities. It was initiated by two German states to link health information from disparate sources and to organize this information in a user-friendly way. The web portal focuses on reducing preventable lifestyle-related risk factors associated with noncommunicable diseases, including physical inactivity, unhealthy diet, tobacco use, and the harmful use of alcohol. This local initiative has the potential for scaling up and can serve as a blueprint for other areas that have or will acquire internet access. PMID:23923103

The Operating Missions as Nodes on the Internet (OMNI) project at NASA's Goddard Space flight Center (GSFC), is demonstrating the use of standard Internet protocols for spacecraft communication systems. This year, demonstrations of Internet access to a flying spacecraft have been performed with the UoSAT-12 spacecraft owned and operated by Surrey Satellite Technology Ltd. (SSTL). Previously, demonstrations were performed using a ground satellite simulator and NASA's Tracking and Data Relay Satellite System (TDRSS). These activities are part of NASA's Space Operations Management Office (SOMO) Technology Program, The work is focused on defining the communication architecture for future NASA missions to support both NASA's "faster, better, cheaper" concept and to enable new types of collaborative science. The use of standard Internet communication technology for spacecraft simplifies design, supports initial integration and test across an IP based network, and enables direct communication between scientists and instruments as well as between different spacecraft, The most recent demonstrations consisted of uploading an Internet Protocol (IP) software stack to the UoSAT- 12 spacecraft, simple modifications to the SSTL ground station, and a series of tests to measure performance of various Internet applications. The spacecraft was reconfigured on orbit at very low cost. The total period between concept and the first tests was only 3 months. The tests included basic network connectivity (PING), automated clock synchronization (NTP), and reliable file transfers (FTP). Future tests are planned to include additional protocols such as Mobile IP, e-mail, and virtual private networks (VPN) to enable automated, operational spacecraft communication networks. The work performed and results of the initial phase of tests are summarized in this paper. This work is funded and directed by NASA/GSFC with technical leadership by CSC in arrangement with SSTL, and Vytek Wireless.

Internet has changed the way we live and work. Advent of this technology has fundamentally transformed our lives the way invention of automobile changed how our lives and cities looked and worked before. Practically no information is available on the use of Internet for health by the people of Pakistan. The Objectives of the study were to assess the access and utilization pattern of Internet by university students in Islamabad, with emphasis on the healthcare information seeking. An anonymous, self-administered, and pre-tested questionnaire with questions on the access, and usage pattern of Internet, seeking health care information online, and belief about reliability of such information; was distributed to only those students who were enrolled in masters or higher degree programs. A total of 600 students were approached and 598 (99.7%) completed the questionnaires. The mean age of students was 23.5 years (range 19-40). The majority of students (423) were enrolled in masters program. Four hundred and sixty-eight students (78.26%) students had access to the computer either at home or at their university hostel. While 304 (50.84%) students had Internet access at home or in their university hostel. Out of 304 students who reported having access to Internet in the past three months, one hundred and thirty-nine (43.4%) students replied affirmatively to the question of having used Internet for seeking health care information. And 109 (78.4%) thought that such information was reliable. Out of 139 students who had used Internet for seeking health information, 35 (25.2%) students replied affirmatively to the question of having discussed health information obtained from Internet with their doctor/physician whom they visited for any illness/treatment. Majority of Islamabad university students in this study had access to computer and Internet. Young and healthy state of this educated age group perhaps accounts for limited use of Internet for seeking healthcare related

Internet use is widespread, but little is known about Internet use for cancer information among Latinos, especially those who rely on safety net clinics. The authors investigated access to and intended use of the Internet for cancer information among low income, immigrant Latinos predominately from Central and South America. A cross-sectional study of 1,273 Latinos 21 years and older attending safety net clinics or health fairs was conducted from June 2007 to November 2008. The authors used logistic regression models to evaluate associations of age, acculturation, psychosocial factors and other covariates with Internet access and intended use of the Internet for cancer information among those with access. Of the sample, 44% reported Internet access. Higher information self-efficacy and greater trust in the Internet were independently associated with Internet access (p= .05 and p < .001, respectively). Among those with access, 53.8% reported they intended to seek cancer help online if they needed information. Those with younger age and higher acculturation, education and self-efficacy had higher odds of intended Internet use for cancer information, considering covariates. In addition, those with high (vs. low) perceived risk of cancer (OR = 1.76; 95% CI [1.14, 2.73]; p = .01) and higher levels of trust in online health information (OR = 1.47 per one-point increase; 95% [CI 1.19, 1.82]; p = .0004) were more likely to intend to seek cancer information online. These findings that Internet access is fairly high in the immigrant Latino population and that the Internet is a trusted source of cancer information suggest that the Internet may be a channel for cancer control interventions.

Mobile access to the Internet: from personal bubble to satellites

NASA Astrophysics Data System (ADS)

Gerla, Mario

2001-10-01

Mobile, wireless access and networking has emerged in the last few years as one of the most important directions of Internet growth. The popularity of mobile, and, more generally, nomadic Internet access is due to many enabling factors including: (a) emergence of meaningful applications tailored to the individual on the move; (b) small form factor and long battery life; (c) efficient middleware designed to support mobility; and, (d) efficient wireless networking technologies. A key player in the mobile Internet access is the nomad, i.e. the individual equipped with various computing and I/O gadgets (cellular phone, earphones, GPS navigator, palm pilot, beeper, portable scanner, digital camera, etc.). These devices form his/her Personal Area Network or PAN or personal bubble. The connectivity within the bubble is wireless (using for example a low cost, low power wireless LAN such as Bluetooth). The bubble can expand and contract dynamically depending on needs. It may temporarily include sensors and actuators as the nomad walks into a new environment. In this paper, we identify the need for the interconnection of the PAN with other wireless networks in order to achieve costeffective mobile access to the Internet. We will overview some key networking technologies required to support the PAN (eg, Bluetooth). We will also discuss an emerging technology, Ad Hoc wireless networking which is the natural complement of the PAN in sparsely populated areas. Finally, we will identify the need for intelligent routers to assist the mobile user in the selection of the best Internet access strategy.

Access to the internet at home may be an important barrier to electronic health (eHealth) smoking cessation interventions. The current study explored possible sociodemographic disparities in access to the internet at home among veteran smokers. Data from participants proactively recruited and enrolled in a randomized smoking cessation effectiveness trial (N = 408) that compared a web-based smoking cessation intervention to Veterans Affairs (VA) usual care were used to examine the demographic attributes of smokers with and without internet access at home. Multivariable logistic regression was used to examine associations between demographic factors and home internet access. Data from patients randomized to the internet arm of the study (N = 205) were used to ascertain correlates of utilization of the intervention website. While the majority of the sample (82 %) endorsed access to the internet at home, veterans who were African-American, older, and not married were significantly less likely to have home internet access. Veterans who were African-American, older, less educated, had longer travel times to the nearest VA facility, and increased nicotine dependence were less likely to access the internet on a daily basis. While several sociodemographic variables (e.g., age, race, education, employment) were related to utilization of a free membership to a commercial, web-based smoking cessation intervention in bivariate analyses, only access to the internet at home was related to use of the smoking cessation site in adjusted results. These results highlight gaps in internet access and use among veterans and additionally underscore the importance of improving accessibility of eHealth interventions for low-income, minority, and socially disadvantaged veteran populations.

Youth experiencing homelessness are at a risk for a variety of adverse outcomes. Given the widespread use of the internet and social media, these new technologies may be used to address their needs and for outreach purposes. However, little is known about how this group uses these resources. This study investigated how homeless adolescents use these technologies for general and health-related purposes, whether the scope of their use changes with housing status, and their interest in a website dedicated to youth experiencing homelessness. A convenience sample of youth aged 18 to 21 years was recruited from a youth-specific homeless shelter. All participants completed a 47-item survey, with 10 individuals completing a semistructured interview. Descriptive statistics, exact testing, logistic regression, and generalized estimating equation modeling was performed for quantitative data analysis. Interviews were transcribed verbatim, and NVivo 10 (QSR International) was employed to facilitate double coding and thematic analysis. A total of 87 participants completed the survey with a mean age of 19.4 (SD 1.1) years. While experiencing homelessness, 56% (49/87) accessed the internet at least once a day, with 86% (75/87) accessing once a week. Access to a smartphone was associated with a 3.03 greater odds of accessing the internet and was the most frequently used device (66% of participants, 57/87). While experiencing homelessness, subjects reported a 68% decreased odds in internet access frequency (odds ratio [OR] 0.32, P<.001), 75% decreased odds in spending greater amounts of time on the internet (OR 0.25, P<.001), and an 87% decreased odds of social media use (OR 0.13, P=.01). Ten participants completed the semistructured interview. Several themes were identified, including (1) changes in internet behaviors while experiencing homelessness, (2) health status as a major concern and reason for Internet use, and (3) interest in a website dedicated to youth experiencing

To assess Internet access and usage patterns among high-risk youth involved in the juvenile justice system, and to determine if health information technology tools might play a useful role in more actively engaging this population in their health care. A sample of 79 youth between the ages of 13 and 18 years old underwent a structured interview while detained in a large, Northern California juvenile detention facility. After an institutional review board-approved assent/consent process, youth discussed their typical Internet use when not detained, as well as their attitudes toward online access to their personal health information (PHI). Detained youth from predominantly underserved, minority communities, reported high levels of access to the Internet while outside of the detention setting, with 97% reporting using the Internet at least once per month and 87% at least weekly. Furthermore, 90% of these youth expressed interest in accessing their PHI online and sharing it with either parents or physicians. Detained adolescents describe unexpectedly high usage of the Internet and online resources when they are outside of the juvenile hall setting. These youth show an interest in, and may benefit from, accessing their PHI online. Further studies are needed to understand the potential health benefits that may be realized by engaging this population through online tools.

Internet access produces misinformed patients: managing the confusion.

PubMed

Hungerford, David S

2009-09-01

The Internet has produced a truly phenomenal increase in access to information. This is really only helpful to patients if the information is filtered and appropriate to their specific needs. Too often patients access information about conditions they have self-diagnosed and bring it to the consultation with their physician, who then has to spend time disabusing the patients of the misinformation they have accumulated. Patients also return home from their initial consultation, access the Internet, and come up with all manner of promotional information from companies and even orthopedic practices that they want explained to them by their physician. It is the overwhelming conclusion of orthopedic specialists that this kind of Internet use is actually a burden for them in caring for patients and is not contributing to patient enlightenment. It does not have to be this way, if physicians will do just 2 things: first, create white papers for patients that address common current questions, such as surgical approach or bearing surfaces for implants and why we do what we do. This is a huge time saver and will preempt many questions. Second, develop their own website or select excellent nonprejudicial sites to which they can refer patients. To do less will invite a neverending parade of questions irrelevant to patient welfare.

The internet is increasingly being used worldwide in imparting medical education and improving its delivery. It has become an important tool for healthcare professionals training but the data on its use by medical students in developing countries is lacking with no study on the subject from Pakistan. This study was, therefore, carried out with an aim to evaluate the pattern of internet access and utilization by medical students in Pakistan. A structured pre-tested questionnaire was administered to a group of 750 medical students in clinical years studying at various public and private medical colleges in Lahore. The questions were related to patterns of internet access, purpose of use and self reported confidence in performing various internet related tasks, use of health related websites to supplement learning and the problems faced by students in using internet at the institution. A total of 532 medical students (70.9%) returned the questionnaire. The mean age of study participants was 21.04 years (SD 1.96 years). Majority of the respondents (84.0%) reported experience with internet use. About half of the students (42.1%) were using internet occasionally with 23.1%, 20.9% and 13.9% doing so frequently, regularly and rarely respectively. About two third of the students (61.0%) stated that they use internet for both academic and professional activities. Most of the participants preferred to use internet at home (70.5%). Self reported ability to search for required article from PubMed and PakMedinet was reported by only 34.0% of the entire sample. Students were moderately confident in performing various internet related tasks including downloading medical books from internet, searching internet for classification of diseases and downloading full text article. Health related websites were being accessed by 55.1% students to supplement their learning process. Lack of time, inadequate number of available computers and lack of support from staff were cited as the most

Majority of the respondents (84.0%) reported experience with internet use. About half of the students (42.1%) were using internet occasionally with 23.1%, 20.9% and 13.9% doing so frequently, regularly and rarely respectively. About two third of the students (61.0%) stated that they use internet for both academic and professional activities. Most of the participants preferred to use internet at home (70.5%). Self reported ability to search for required article from PubMed and PakMedinet was reported by only 34.0% of the entire sample. Students were moderately confident in performing various internet related tasks including downloading medical books from internet, searching internet for classification of diseases and downloading full text article. Health related websites were being accessed by 55.1% students to supplement their learning process. Lack of time, inadequate number of available computers and lack of support from

China has historically reported a low prevalence of eating disorders. However, the rapid social and economic development of this country as well as Western ideals widely disseminated by television and the Internet have led to distinct patterns of behavioral choices that could affect eating disorder risk. Thus, the current study explored the relation between disordered eating and media use. Participants were females from the 2009 wave of the China Health and Nutrition Survey (N = 1,053). Descriptive statistics were obtained and logistic regression models, stratified by age (adolescents ages 12-17 years and adults ages 18-35 years), were used to evaluate the association of media use with disordered eating. In adolescents, 46.8% had access to the Internet and those with access averaged one hour per day each of Internet and television use. In adults, 41.4% had access to the Internet, and those with access averaged 1 h per day of Internet use and 2 h per day of television use. Internet access was significantly associated with a subjective belief of fatness (OR = 2.8, 95% CI: 1.6, 4.9) and worry over losing control over eating (OR = 4.8, 95% CI: 2.3, 9.8) only in adults. These findings help characterize the overall pattern of media use and report of eating disorder symptoms in a large sample of female Chinese adolescents and adults. That Internet access in adults was significantly associated with disordered eating cognitions might suggest that media access negatively influences these domains; however, more granular investigations are warranted. © 2014 Wiley Periodicals, Inc.

Objective Communication inequalities deepen health disparities even when internet access is achieved. The goal of this study is to understand how a range of barriers may inhibit individuals from low socioeconomic position (SEP) from engaging with online health information even when it is freely available. Materials and methods Detailed data were collected from 118 low-SEP individuals from a randomized controlled trial providing internet access. Measures triangulated the health-seeking experience through internet use tracked in real-time, call log data, and self-reported barriers. Negative binomial regression models were fitted with technology and perceived predictors, and our outcome, health information seeking, and then stratified by medical status. Results Participants experienced a median of two computer issues (median 6 days) and two internet issues (median 6.5 days). Duration of internet problems was associated with a decrease in the rate of internet health information seeking by a factor of 0.990 (P = .03) for each additional day. Participants with a medical problem who were frustrated in their search for health information had half the rate of health information seeking of those who were not frustrated (incidence rate ratio = 0.395, P = .030). Discussion Despite IT support, participants still experienced internet connectivity issues that negatively impacted their health information seeking. Frustration in their search to find information may serve as an additional barrier to those who have medical issues. Conclusion After initial internet access, a second-level digital divide emerged due to connectivity issues, highlighting the need to understand the complex network of barriers experienced by low-SEP internet users.

Using data from the 2013 American Community Survey, we found that 24.3 million people (about 1 in 4) who were either eligible for Medicaid/Children's Health Insurance Program (CHIP) or appeared likely to shop for Qualified Health Plan (QHP) lacked residential high-speed Internet. Specifically, 28.6% or 18.9 million people eligible for Medicaid/CHIP and 17.1% or 5.5 million people who appeared likely to shop for a QHP did not have high-speed Internet in the home. For both the Medicaid/CHIP eligible and those likely to shop for a QHP, the proportion of people living in households without Internet varied substantially by race, geography, and other socio-demographic characteristics. © The Author(s) 2016.

Prescription for trouble: Medicare Part D and patterns of computer and internet access among the elderly.

PubMed

Wright, David W; Hill, Twyla J

2009-01-01

The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 specifically encourages Medicare enrollees to use the Internet to obtain information regarding the new prescription drug insurance plans and to enroll in a plan. This reliance on computer technology and the Internet leads to practical questions regarding implementation of the insurance coverage. For example, it seems unlikely that all Medicare enrollees have access to computers and the Internet or that they are all computer literate. This study uses the 2003 Current Population Survey to examine the effects of disability and income on computer access and Internet use among the elderly. Internet access declines with age and is exacerbated by disabilities. Also, decreases in income lead to decreases in computer ownership and use. Therefore, providing prescription drug coverage primarily through the Internet seems likely to maintain or increase stratification of access to health care, especially for low-income, disabled elderly, who are also a group most in need of health care access.

Internet access and use by COPD patients in the National Emphysema/COPD Association Survey

2014-01-01

Background Technology offers opportunities to improve healthcare, but little is known about Internet use by COPD patients. We tested two hypotheses: Internet access is associated with socio-demographic disparities and frequency of use is related to perceived needs. Methods We analyzed data from a 2007–2008 national convenience sample survey of COPD patients to determine the relationship between Internet access and frequency of use with demographics, socio-economic status, COPD severity, and satisfaction with healthcare. Results Among survey respondents (response rate 7.2%; n = 914, 59.1% women, mean age 71.2 years), 34.2% reported lack of Internet access, and an additional 49% had access but used the Internet less than weekly. Multivariate models showed association between lack of access and older age (OR 1.10, 95% CI 1.07, 1.13), lower income (income below $30,000 OR 2.47, 95% CI 1.63, 3.73), less education (high school highest attainment OR 2.30, 95% CI 1.54, 3.45), comorbid arthritis or mobility-related disease (OR 1.56, 95% CI 1.05, 2.34). More frequent use (at least weekly) was associated with younger age (OR 0.95, 95% CI 0.93, 0.98), absence of cardiovascular disease (OR 0.48, 95% CI 0.29, 0.78), but with perception of needs insufficiently met by the healthcare system, including diagnostic delay (OR 1.72, 95% CI 1.06, 2.78), feeling treated poorly (OR 2.46, 95% CI 1.15, 5.24), insufficient physician time (OR 2.29, 95% CI 1.02, 5.13), and feeling their physician did not listen (OR 3.14, 95% CI 1.42, 6.95). Conclusions An analysis of the characteristics associated with Internet access and use among COPD patients identified two different patient populations. Lack of Internet access was a marker of socioeconomic disparity and mobility-associated diseases, while frequent Internet use was associated with less somatic disease but dissatisfaction with care.

History, structure, and function of the Internet.

PubMed

Glowniak, J

1998-04-01

The Internet stands at the forefront of telecommunications in medicine. This worldwide system of computers had its beginnings in networking projects in the United States and western Europe in the 1960s and 1970s. The precursor of the Internet was ARPANET, a long-distance telecommunication network funded by the Department of Defense that linked together computers throughout the United States. In the 1980s, ARPANET was superseded by NSFNET, a series of networks created by the National Science Foundation, which established the present-day structure of the Internet. The physical structure of the Internet resembles and is integrated with the telephone system. Long-distance data transport services are provided by large telecommunication companies, called network service providers (NSPs), through high-capacity, high-speed national and international fiber optic cables. These transport services are accessed through Internet service providers, ISPs. ISPs, the equivalent of regional Bell operating companies, provide the physical link to the NSPs for individuals and organizations. Telecommunications on the Internet are standardized by a set of communications protocols, the TCP/IP protocol suite, that describe routing of messages over the Internet, computer naming conventions, and commonly used Internet services such as e-mail. At present, the Internet consists of over 20 million computer worldwide and is continuing to grow at a rapid rate. Along with the growth of the Internet, higher speed access methods are offering a range of new services such as real-time video and voice communications. Medical education, teaching, and research, as well as clinical practice, will be affected in numerous different ways by these advances.

The Internet may represent an opportunity for health care providers in the emergency department (ED) to deliver discharge instructions and after-care educational materials electronically to patients and their caregivers. The objectives of this study were to determine the prevalence of Internet access and use among caregivers of children who visit the ED and to evaluate their interest in receiving after-care communication and educational material electronically. We distributed a self-administered survey to a convenience sample of English-speaking caregivers of children who presented to the ED of an urban, academic, pediatric hospital during November and December 2009. The survey was distributed to and completed by 509 English-speaking respondents. Of the participants, 423 (83.1%) of 509 identified themselves as black/African American, and 397 (77.9%) of 509 were publicly insured. Of the participants, 503 of 509 (98.9%; 95% confidence interval [CI], 97.9%-99.8%) reported that they have access to the Internet. Of the participants with Internet access, 312 of 503 (62.0%; 95% CI, 57.8%-66.3%) have access at home, 166 of 503 (33.0%; 95% CI, 28.9%-33.1%) have access at work, and 112 of 503 (22.3%; 95% CI, 18.6%-25.9%) have access by mobile phone. When asked about electronic communication and social networking, 483 of 503 (96.0%; 95% CI, 94.3%-97.7%) have an e-mail account, and 304 of 503 (60.4%; 95% CI, 56.2%-64.7%) have a Facebook account. Furthermore, 353 of 503 (70.1%; 95% CI, 66.2%-74.2%) reported accessing the Internet daily, whereas 128 of 503 (25.4%; 95% CI, 21.6%-29.3%) access the Internet at least 2 to 6 times per week. Among all respondents, interest in receiving communication from the ED only electronically was expressed by 259 of 509 participants (50.9%; 95% CI, 46.5%-55.2%). Approximately one third of the participants (173/509 [34%; 95% CI, 29.9%-38.1%]) expressed interest in an electronic channel for communication between the ED and their child's patient

Blauassociate, Andrew

1993-09-01

While many people in government, education, and industry have lauded the potential educational value of Internet access for students in grades K-12, there is as yet no legal or regulatory framework within which this new medium is being offered to students. The Communications Policy Forum, a nonpartisan project of the Electronic Frontier Foundation, recently convened a roundtable to discuss some of the legal issues that arise when K-12 schools provide Internet access to their students. Approximately 15 people, representing carriers who provide connections to the Internet, schools or school systems who are connected to the Internet, and legal experts with expertise in this and related areas, met to discuss questions of legal liability as this new medium enters an educational setting for minors. The following attempts to capture the major issues, suggestions, and directions for further collaborative efforts raised during the course of that discussion. In brief, the group identified statutory language aimed at other types of electronic communication that may offer some guidance; was briefed on a host of state laws that could be used to prosecute providers of certain materials found on the Internet; and concluded that there is no case law that clearly applies to this setting. The discussion revealed an interest in anticipating issues and developing responses before problems arose, and the need for shared approaches to allow carriers to move forward in serving and expanding this field. Members of the group offered to pursue these issues jointly and agreed upon a handful of concrete steps for further exploration and discussion.

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.

2001-02-01

The Internet and the World Wide Web have revolutionised communication and provide a unique forum for the exchange of information. It has been proposed that the Internet has given the public more access to medical information resources and improved patient education. This study assessed the impact of the Internet on the availability of information on wound care management. The search phrases 'wound care', 'wound healing' and 'wounds' were analysed using a powerful Metacrawler search engine (www.go2net.com). Web site access was classified according to the target audience (wound-care specialists, other health professionals, patients) and the author (societies, institutions or commercial companies). The largest proportion of web sites were commercially based (32%). Of the total number, 23% specifically targeted patients, mostly by advertising. Only 20% were aimed at wound specialists. Extensive surfing was required to obtain wound-care information, and objective information sites were under-represented. Regulated, easily accessible, objective information sites on wound-healing topics are needed for improved patient education and to balance the existing commercial bias.

Objective: Although computer technologies are now widely used in medicine, little is known about its use among medical students in Iran. The aim of this study was to determine the competence and access to computer and internet among the medical students. Methods: In this descriptive study, medical students of Shahid Sadoughi University of Medical Science, Yazd, Iran from the fifth years were asked to answer a questionnaire during a time-tabled lecture slot. The chi-square test was used to compare the frequency of computer and internet use between the two genders, and the level of statistical significance for all test was set at 0.05. Results: All the students have a personal computer and internet access. There were no statistically significant differences between men and women for the computer and internet access, use wireless device to access internet, having laptop and e-mail address and the difficulties encountered using internet. The main reason for less utilization of internet was slow speed of data transfer. Conclusions: Because of the wide range of computer skills and internet information among medical students in our institution, a single computer and internet course for all students would not be useful nor would it be accepted.

Automatic video identification is important for indexing, search purposes, and removing illegal material on the Internet. By combining a high-speed correlation engine and web-scanning technology, we developed the Fast Recognition Correlation system (FReCs), a video identification system for the Internet. FReCs is an application thatsearches through a number of websites with user-generated content (UGC) and detects video content that violates copyright law. In this paper, we describe the FReCs configuration and an approach to investigating UGC websites using FReCs. The paper also illustrates the combination of FReCs with an optical correlation system, which is capable of easily replacing a digital authorization sever in FReCs with optical correlation.

Healthy People 2020 (HP2020) aims to improve population health outcomes through several objectives, including health communication and health information technology. We used 7 administrations of the Health Information National Trends Survey to examine HP2020 goals toward access to the Internet through broadband and mobile devices (N = 34 080). We conducted descriptive analyses and obtained predicted marginals, also known as model-adjusted risks, to estimate the association between demographic characteristics and use of mobile devices. The HP2020 target (7.7% of the US population) for accessing the Internet through a cellular network was surpassed in 2014 (59.7%), but the HP2020 target (83.2%) for broadband access fell short (63.8%). Sex and age were associated with accessing the Internet through a cellular network throughout the years (Wald F test, P <.05). The increase in the percentage of people accessing the Internet through mobile devices presents an opportunity for technology-based health interventions that should be explored.

To increase continuing education accessibility, nurses around the world are turning to Web-based instruction. However, for Internet education to be successful, particularly in developing countries, nurses must have access to computers and the Internet as well as positive attitudes toward this form of learning. As part of a distance education project for nurses of the Tianjin Municipality in China, a survey of nurses was conducted to examine their sources of professional knowledge as well as their computer and Internet access and attitudes. The attitudes of the nurses were generally positive, and there was evidence of rapidly increasing use of and access to computers and the Internet. This article reports the results of that survey and their implications for Web-based teaching of Chinese nurses.

Patients with adequate health literacy were more likely to own a mobile phone or smartphone in comparison with patients having marginal or low literacy (mobile phone ownership: 96.8 vs. 95.2 vs. 90.1%, respectively, P < 0.001; smartphone ownership: 70.6 vs. 62.5 vs. 40.1%, P < 0.001) and to report text messaging (78.6 vs. 75.2 vs. 53.1%, P < 0.001). They were also more likely to have access to the Internet from their home (92.1 vs. 74.7 vs. 44.9%, P < 0.001) and to report using the Internet for email (93.0 vs. 75.7 vs. 38.5%, P < 0.001), browsing the web (93.9 vs. 80.2 vs. 44.5%, P < 0.001), accessing health information (86.3 vs. 75.5 vs. 40.8%, P < 0.001), and communicating with providers (54.2 vs. 29.8 vs. 13.0%, P < 0.001). Relationships remained significant in multivariable analyses controlling for relevant covariates. Results reveal that literacy-related disparities in technology access and use are widespread, with lower literate patients being less likely to own smartphones or to access and use the Internet, particularly for health reasons. Future interventions should consider these disparities and ensure that health promotion activities do not further exacerbate disparities. © 2014 John Wiley & Sons Ltd.

An Internet of Things Example: Classrooms Access Control over Near Field Communication

The Internet of Things is one of the ideas that has become increasingly relevant in recent years. It involves connecting things to the Internet in order to retrieve information from them at any time and from anywhere. In the Internet of Things, sensor networks that exchange information wirelessly via Wi-Fi, Bluetooth, Zigbee or RF are common. In this sense, our paper presents a way in which each classroom control is accessed through Near Field Communication (NFC) and the information is shared via radio frequency. These data are published on the Web and could easily be used for building applications from the data collected. As a result, our application collects information from the classroom to create a control classroom tool that displays access to and the status of all the classrooms graphically and also connects this data with social networks.

Utilizing the ubiquitous personal computer as a platform, and Integrated Services Digital Network (ISDN) communications, cost effective medical information access and consultation can be provided for physicians at geographically remote sites. Two modes of access are provided: information retrieval via the Internet, and medical consultation video conferencing. Internet access provides general medical information such as current treatment options, literature citations, and active clinical trials. During video consultations, radiographic and pathology images, and medical text reports (e.g., history and physical, pathology, radiology, clinical laboratory reports), may be viewed and simultaneously annotated by either video conference participant. Both information access modes have been employed by physicians at community hospitals which are members of the Jefferson Cancer Network, and oncologists at Thomas Jefferson University Hospital. This project has demonstrated the potential cost effectiveness and benefits of this technology. Images Figure 1 Figure 2 Figure 3 PMID:8563397

Online partner seeking is associated with sexual risk behavior among young adults (specifically men who have sex with men), but this association has yet to be explored among a probability sample of adolescents. Moreover, cell phone internet access and sexual risk taking online and offline have not been explored. A probability sample (N = 1,831) of Los Angeles Unified School District high school students was collected in 2011. Logistic regression models assessed relationships between specific sexual risk behaviors (online sexual solicitation, seeking partners online, sex with internet-met partners, condom use) and frequency of internet use, internet access points, and demographics. Students with cell phone internet access were more likely to report being solicited online for sex, being sexually active, and having sex with an internet-met partner. Bisexual-identifying students reported higher rates of being approached online for sex, being sexually active, and not using condoms at last sex. Gay, lesbian, and questioning (GLQ) students were more likely to report online partner seeking and unprotected sex at last sex with an internet-met partner. Additionally, having sex with an internet-met partner was associated with being male, online sexual solicitation, and online partner seeking. Internet- and school-based sexual health programs should incorporate safety messages regarding online sexual solicitation, seeking sex partners online, and engaging in safer sex practices with all partners. Programs must target adolescents of all sexual identities, as adolescents may not yet be “out,” and bisexual and GLQ adolescents are more likely to engage in risky sex behaviors. PMID:25344027

2015-01-01

According to the MODE model of attitude-to-behavior processes, attitude accessibility augments attitude-behavior correspondence, reflecting an automatic influence of attitudes on behavior. We therefore tested whether attitude accessibility moderates the attitude-behavior relationship in a context that is governed by characteristically automatic behavior, namely driving. In study 1 (correlational design), participants (N=130) completed online questionnaire measures of the valences and accessibilities of their attitudes towards speeding. Two weeks later, online questionnaire measures of subsequent speeding behavior were obtained. Attitude valence was a significantly better predictor of behavior at high (mean+1SD) versus low (mean-1SD) levels of attitude accessibility. In study 2 (experimental design), attitude accessibility was manipulated with a repeated attitude expression task. Immediately after the manipulation, participants (N=122) completed online questionnaire measures of attitude valence and accessibility, and two weeks later, subsequent speeding behavior. Increased attitude accessibility in the experimental (versus control) condition generated an increase in attitude-behavior correspondence. The findings are consistent with the MODE model's proposition that attitudes can exert an automatic influence on behavior. Interventions to reduce speeding could usefully increase the accessibility of anti-speeding attitudes and reduce the accessibility of pro-speeding attitudes. Copyright © 2014 Elsevier Ltd.

Subdividing the Digital Divide: Differences in Internet Access and Use among Rural Residents with Medical Limitations

PubMed Central

2011-01-01

Background Access to health care is often contingent upon an individual’s ability to travel for services. Certain groups, such as those with physical limitations and rural residents, have more travel barriers than other groups, reducing their access to services. The use of the Internet may be a way for these groups to seek care or information to support their health care needs. Objective The purpose of this study was to examine Internet use among those whose are, for medical reasons, limited in their ability to travel. We also examined disparities in Internet use by race/ethnicity and rural residence, particularly among persons with medical conditions. Methods We used data from the 2001 National Household Travel Survey (NHTS), a nationally representative sample of US households, to examine Internet use among individuals with medical conditions, rural residents, and minority populations. Internet use was defined as any use within the past 6 months; among users, frequency of use and location of use were explored. Control variables included sociodemographics, family life cycle, employment status, region, and job density in the community. All analyses were weighted to reflect the complex NHTS sampling frame. Results Individuals with medical conditions were far less likely to report Internet use than those without medical conditions (32.6% vs 70.3%, P < .001). Similarly, rural residents were less likely to report Internet access and use than urban residents (59.7% vs 69.4%, P < .001). Nationally, 72.8% of white respondents, versus 65.7% of persons of “other” race, 51.5% of African Americans, and 38.0% of Hispanics reported accessing the Internet (P < .001). In adjusted analyses, persons with medical conditions and minority populations were less likely to report Internet use. Rural-urban differences were no longer significant with demographic and ecological characteristics held constant. Conclusions This analysis confirmed previous findings of a digital divide

Impact of patient access to Internet health records on glaucoma medication: randomized controlled trial.

PubMed

Kashiwagi, Kenji; Tsukahara, Shigeo

2014-01-15

Glaucoma is one of the leading causes of blindness. Reduction of intraocular pressure is the only proven way to prevent progression of glaucomatous optic neuropathy. The majority of glaucoma patients need to use antiglaucoma ophthalmic solutions over the course of their life. Thus, good adherence and persistency of glaucoma treatment are important factors for better glaucoma care. The purpose of this study was to investigate the impact of an Internet-based glaucoma care support system on glaucoma medication use. Patients were randomly divided into two groups. The non-Internet access (NIA) group consisted of patients who had access to the Internet-based glaucoma care support system during the 4-year period only when they were examined by ophthalmologists. The Internet access (IA) group consisted of patients who had the same Internet-based glaucoma care support system access as the NIA group for the first 2 years following enrollment but who were also given free access to the glaucoma care support system for the remaining 2 years. Changes in glaucoma medication use were investigated. In total, 81 patients in the IA group and 90 patients in the NIA group satisfied the study protocol. The number of antiglaucoma ophthalmic solutions used during the study period significantly increased in the NIA group (P<.03) but not in the IA group. The percentages of patients with unchanged, increased, and decreased antiglaucoma ophthalmic solution use during the study period were 61.1% (55/90), 17.8% (16/90), and 3.3% (3/90), respectively, in the NIA group, and 56.8% (46/81), 8.6% (7/81), and 13.6% (11/81), respectively, in the IA group (P<.001). Internet access significantly shifted from an increasing intraocular pressure trend to a decreasing trend in the IA group (P=.002) among the patients who did not have any medication changes. Allowing patients to browse their medical data may reduce the use and improve the effectiveness of glaucoma medication. UMIN-CTR Clinical Trial Number

High-speed holographic correlation system by a time-division recording method for copyright content management on the internet

NASA Astrophysics Data System (ADS)

Watanabe, Eriko; Ikeda, Kanami; Kodate, Kashiko

2012-10-01

Using a holographic disc memory on which a huge amount of data can be stored, we constructed an ultra-high-speed, all-optical correlation system. In this method, multiplex recording is, however, restricted to "one page" on "one spot." In addition, signal information must be normalized as data of the same size, even if the object data size is smaller. Therefore, this system is difficult to apply to part of the object data scene (i.e., partial scene searching and template matching), while maintaining high accessibility and programmability. In this paper, we develop a holographic correlation system by a time division recording method that increases the number of multiplex recordings on the same spot. Assuming that a four-channel detector is utilized, 15 parallel correlations are achieved by a time-division recording method. Preliminary correlation experiments with the holographic optical disc setup are carried out by high correlation peaks at a rotational speed of 300 rpm. We also describe the combination of an optical correlation system for copyright content management that searches the Internet and detects illegal contents on video sharing websites.

Ref Tek Ultra-low Power Seismic Recorder With Low-cost High Speed Internet Telemetry U An Advanced Real-time Seismological Data Acquisition System

NASA Astrophysics Data System (ADS)

Passmore, P.; Zimakov, L.; Rozhkov, M.

The 3rd Generation Seismic Recorder, Model 130-01, has been designed to be easier to use - more compact, lighter in weight, lower power, and requires less maintenance than other recorders. Not only is the hardware optimized for field deployments, soft- ware tools as well have been specially developed to support both field and base station operation. The 130's case is a clamshell design, inherently waterproof, with easy access to all user features on the top of the unit. The 130 has 6 input/output connectors, an LCD display, and a removable lid on top of the case. There are two Channel input connectors on a 6-channel unit (only one on a 3-channel unit), a Terminal connector for setup and control, a Net connector combining Ethernet and Serial PPP for network access, a 12 VDC Power connector, and a GPS receiver connector. The LCD display allows the user to monitor the status of various sub systems within the 130 without having a terminal device attached. For storing large amounts of data the IBM MicrodriveTM is offered. User setup, control and status monitoring is done either with a Personal Digital Assistant (PDA) (Palm OS compatible) using our Palm Field Controller (PFC) software or from a PC/workstation using our REF TEK Network Controller (RNC) GUI interface. StarBand VSAT is the premier two-way, always-on, high-speed satellite Internet ser- vice. StarBand means high-speed Internet without the constraints and congestion of land-based cable or telephone networks. StarBand uses a single satellite dish antenna for receiving and for sending dataUno telephone connection is needed. The hardware ° cost is much less than standard VSAT equipment with double or single hop transmis- sion. REF TEK protocol (RTP) provides end-to-end error-correcting data transmission and command/control. StarBandSs low cost VSAT provides two-way, always-on, high speed satellite Internet data availability. REF TEK and StarBand create the most ad- vanced real-time seismological data acquisition

Highball: A high speed, reserved-access, wide area network

Mills, David L.; Boncelet, Charles G.; Elias, John G.; Schragger, Paul A.; Jackson, Alden W.

1990-01-01

A network architecture called Highball and a preliminary design for a prototype, wide-area data network designed to operate at speeds of 1 Gbps and beyond are described. It is intended for applications requiring high speed burst transmissions where some latency between requesting a transmission and granting the request can be anticipated and tolerated. Examples include real-time video and disk-disk transfers, national filestore access, remote sensing, and similar applications. The network nodes include an intelligent crossbar switch, but have no buffering capabilities; thus, data must be queued at the end nodes. There are no restrictions on the network topology, link speeds, or end-end protocols. The end system, nodes, and links can operate at any speed up to the limits imposed by the physical facilities. An overview of an initial design approach is presented and is intended as a benchmark upon which a detailed design can be developed. It describes the network architecture and proposed access protocols, as well as functional descriptions of the hardware and software components that could be used in a prototype implementation. It concludes with a discussion of additional issues to be resolved in continuing stages of this project.

This project was undertaken to explore new options for connecting homes and small businesses to high-speed communications networks, such as the Internet. Fundamental to this inquiry was an interest in looking at options which are newly enabled through changes in technology and regulation, and which go beyond the traditional topdown, centralized model for local access. In particular, the authors focused on opportunities for end-user and community-level investment. This project was intended to investigate the opportunities presented by the decreasing cost of computing and networking platforms, the unbundling of local exchange network elements, and the intelligent endpoints model of networking bestmore » exemplified by the Internet. Do these factors, along with communications technologies such as spread spectrum wireless, digital subscriber line services, and the ability to modulate a communications signal over the electric power line infrastructure, enable new models for end-user investment in intelligent infrastructure as a leverage point for accessing the broadband network? This question was first explored through a two-day conference held at the Freedom Forum in Arlington, Virginia, October 29 and 30, 1996. The workshop addressed issues in the consumer adoption of new communications technologies, use of the electric power line infrastructure, the role of municipalities, and the use of alternative technologies, such as XDSL, satellite, spread spectrum wireless, LMDS, and others. The best of these papers have been further developed, with editorial guidance provided by Harvard, and compiled in the form of a book (The First 100 Feet: New Options for Internet and Broadband Access, Deborah Hurley and James Keller, eds., MIT Press, 1998) to be published as part of the MIT Press Spring 1998 catalogue.

Online access to health records and the ability to exchange secure messages with physicians can improve patient engagement and outcomes; however, the digital divide could limit access to web-based portals among disadvantaged groups. To understand whether sociodemographic differences in patient portal use for secure messaging can be explained by differences in internet access and care preferences. Cross-sectional survey to examine the association between patient sociodemographic characteristics and internet access and care preferences; then, the association between sociodemographic characteristics and secure message use with and without adjusting for internet access and care preference. One thousand forty-one patients with chronic conditions in a large integrated health care delivery system (76% response rate). Internet access, portal use for secure messaging, preference for in-person or online care, and sociodemographic and health characteristics. Internet access and preference mediated some of the differences in secure message use by age, race, and income. For example, using own computer to access the internet explained 52% of the association between race and secure message use and 60% of the association between income and use (Sobel-Goodman mediation test, P<0.001 for both). Education and sex-related differences in portal use remained statistically significant when controlling for internet access and preference. As the availability and use of patient portals increase, it is important to understand which patients have limited access and the barriers they may face. Improving internet access and making portals available across multiple platforms, including mobile, may reduce some disparities in secure message use.

To elicit the preferences and trade-offs of UK general practitioners about key features of health information systems, to help inform the design of such systems in future. A stated choice study to uncover implicit preferences based on a binary choice between scenarios presented in random order. were all 303 general practice members of the UK Internet service provider, Medix who were approached by email to participate. The main outcome measure was the number of seconds delay in system response that general practitioners were willing to trade off for each key system feature: the reliability of the system, the sites from which the system could be accessed and which staff are able to view patient data. Doctors valued speed of response most in information systems but would be prepared to wait 28 seconds to access a system in exchange for improved reliability from 95% to 99%, a further 2 seconds for an improvement to 99.9% and 27 seconds for access to data from anywhere including their own home compared with one place in a single health care premises. However, they would require a system that was 14 seconds faster to compensate for allowing social care as well as National Health Service staff to read patient data. These results provide important new evidence about which system characteristics doctors value highly, and hence which characteristics designers need to focus on when large scale health information systems are planned. © 2010 Blackwell Publishing Ltd.

To determine the frequency of computers in Canadian dental offices and to assess their use; to evaluate Internet access and use in Canadian dental offices; and to compare use of computers and the Internet by Canadian dentists, by the general public and by other dental groups. An anonymous, self-administered survey of Canadian dentists was conducted by mail. A potential mailing list of 14,052 active Canadian dentists was compiled from the 2003 records of provincial regulatory bodies. For each province, 7.8% of the general dentists were randomly selected with the help of computer software. The surveys were mailed to this stratified random sample of 1,096 dentists. The response rate was 28%. Of the 312 respondents, 4 (1%) were in full-time academic positions, 15 (5%) were not practising, and 9 (3%) provided incomplete data. Therefore, 284 survey responses were available for descriptive analysis. Two hundred and fifty-seven (90%) of the respondents had a computer in their primary practice. Computers were used mainly for administrative tasks (accounting, bookkeeping and scheduling) rather than clinical tasks. Internet access was common (185/250 or 74%), and high-speed Internet access (93/250 or 37%) was increasingly common, judging from the results of previous studies on computer use. The main reasons given for not having in-office Internet access were security or privacy concerns and no reported need for or interest in the service. Computer use was high in this sample of Canadian dentists, but a small proportion of dental offices remained without computers. Canadian dentists" use of the Internet was greater than that of American dentists, private enterprise and the North American public in general.

Universal model for collective access patterns in the Internet traffic dynamics: A superstatistical approach

NASA Astrophysics Data System (ADS)

Tamazian, A.; Nguyen, V. D.; Markelov, O. A.; Bogachev, M. I.

2016-07-01

We suggest a universal phenomenological description for the collective access patterns in the Internet traffic dynamics both at local and wide area network levels that takes into account erratic fluctuations imposed by cooperative user behaviour. Our description is based on the superstatistical approach and leads to the q-exponential inter-session time and session size distributions that are also in perfect agreement with empirical observations. The validity of the proposed description is confirmed explicitly by the analysis of complete 10-day traffic traces from the WIDE backbone link and from the local campus area network downlink from the Internet Service Provider. Remarkably, the same functional forms have been observed in the historic access patterns from single WWW servers. The suggested approach effectively accounts for the complex interplay of both “calm” and “bursty” user access patterns within a single-model setting. It also provides average sojourn time estimates with reasonable accuracy, as indicated by the queuing system performance simulation, this way largely overcoming the failure of Poisson modelling of the Internet traffic dynamics.

2007-01-01

Studies performed in the US and other Western countries have documented that physicians generate many clinical questions during a typical day and rely on various information sources for answers. Little is known about the information seeking behaviors of physicians practicing in other countries, particularly those with limited Internet connectivity. We conducted this study to document the perceived barriers to information resources used by medical residents in Iran. Our findings reveal that different perceived barriers exist for electronic versus paper-based resources. Notably, paper-based resources are perceived to be limited by resident time-constraints and availability of resources, whereas electronic resources are limited by cost decentralized resources (such as PDAs) and accessibility of centralized, Internet access. These findings add to the limited literature regarding health information-seeking activities in international healthcare settings, particularly those with limited Internet connectivity, and will supplement future studies of and interventions in such settings.

2015-03-30

The use of Internet-based behavioral programs may be an efficient, flexible method to enhance prenatal care and improve pregnancy outcomes. There are few data about access to, and use of, the Internet via computers and mobile phones among pregnant women. We describe pregnant women's access to, and use of, computers, mobile phones, and computer technologies (eg, Internet, blogs, chat rooms) in a southern United States population. We describe the willingness of pregnant women to participate in Internet-supported weight-loss interventions delivered via computers or mobile phones. We conducted a cross-sectional survey among 100 pregnant women at a tertiary referral center ultrasound clinic in the southeast United States. Data were analyzed using Stata version 10 (StataCorp) and R (R Core Team 2013). Means and frequency procedures were used to describe demographic characteristics, access to computers and mobile phones, and use of specific Internet modalities. Chi-square testing was used to determine whether there were differences in technology access and Internet modality use according to age, race/ethnicity, income, or children in the home. The Fisher's exact test was used to describe preferences to participate in Internet-based postpartum weight-loss interventions via computer versus mobile phone. Logistic regression was used to determine demographic characteristics associated with these preferences. The study sample was 61.0% white, 26.0% black, 6.0% Hispanic, and 7.0% Asian with a mean age of 31.0 (SD 5.1). Most participants had access to a computer (89/100, 89.0%) or mobile phone (88/100, 88.0%) for at least 8 hours per week. Access remained high (>74%) across age groups, racial/ethnic groups, income levels, and number of children in the home. Internet/Web (94/100, 94.0%), email (90/100, 90.0%), and Facebook (50/100, 50.0%) were the most commonly used Internet technologies. Women aged less than 30 years were more likely to report use of Twitter and chat rooms

Objectives: To assess the uptake, usage and acceptability of TOXBASE, the National Poisons Information Service internet toxicology information service. Methods: An observational study of database usage, and a questionnaire of users were undertaken involving users of TOXBASE within the UK between August 1999, when the internet site was launched, and May 2000. The main outcome measures were numbers of registered users, usage patterns on the database, responses to user satisfaction questionnaire. Results: The number of registered users increased from 567 to 1500. There was a 68% increase in accident and emergency departments registered, a 159% increase in general practitioners, but a 324% increase in other hospital departments. Between January 2000 and the end of May there had been 60 281 accesses to the product database, the most frequent to the paracetamol entry (7291 accesses). Ecstasy was the seventh most frequent entry accessed. Altogether 165 of 330 questionnaires were returned. The majority came from accident and emergency departments, the major users of the system. Users were generally well (>95%) satisfied with ease and speed of access. A number of suggestions for improvements were put forward. Conclusions: TOXBASE has been extensively accessed since being placed on the internet (http://www.spib.axl.co.uk). The pattern of enquiries mirrors clinical presentation with poisoning. The system seems to be easily used. It is a model for future delivery of treatment guidelines at the point of patient care. PMID:11777868

Hierarchy Bayesian model based services awareness of high-speed optical access networks

NASA Astrophysics Data System (ADS)

Bai, Hui-feng

2018-03-01

As the speed of optical access networks soars with ever increasing multiple services, the service-supporting ability of optical access networks suffers greatly from the shortage of service awareness. Aiming to solve this problem, a hierarchy Bayesian model based services awareness mechanism is proposed for high-speed optical access networks. This approach builds a so-called hierarchy Bayesian model, according to the structure of typical optical access networks. Moreover, the proposed scheme is able to conduct simple services awareness operation in each optical network unit (ONU) and to perform complex services awareness from the whole view of system in optical line terminal (OLT). Simulation results show that the proposed scheme is able to achieve better quality of services (QoS), in terms of packet loss rate and time delay.

Open Access Internet Resources for Nano-Materials Physics Education

2006-05-01

Because a great deal of nano-material science and engineering relies on crystalline materials, materials physicists have to provide their own specific contributions to the National Nanotechnology Initiative. Here we briefly review two freely accessible internet-based crystallographic databases, the Nano-Crystallography Database (http://nanocrystallography.research.pdx.edu) and the Crystallography Open Database (http://crystallography.net). Information on over 34,000 full structure determinations are stored in these two databases in the Crystallographic Information File format. The availability of such crystallographic data on the internet in a standardized format allows for all kinds of web-based crystallographic calculations and visualizations. Two examples of which that are dealt with in this paper are: interactive crystal structure visualizations in three dimensions and calculations of lattice-fringe fingerprints for the identification of unknown nanocrystals from their atomic-resolution transmission electron microscopy images.

The digital divide: Examining socio-demographic factors associated with health literacy, access and use of internet to seek health information.

This article aims to examine the socio-demographic characteristics associated with access and use of Internet for health-related purposes and its relationship with health literacy. Data were drawn from a health literacy survey ( N = 1046) and analysed using logistic regression. Results show a strong association between health literacy, internet access and use. Socio-demographic characteristics particularly age, education, income, perceived health and social isolation also predict internet access. Thus, in addition to widening access, the movement towards digitisation of health information and services should also consider digital skills development to enable people to utilise digital technology more effectively, especially among traditionally hard-to-reach communities.

Internet of Things is a ubiquitous concept where physical objects are connected over the internet and are provided with unique identifiers to enable their self-identification to other devices and the ability to continuously generate data and transmit it over a network. Hence, the security of the network, data and sensor devices is a paramount concern in the IoT network as it grows very fast in terms of exchanged data and interconnected sensor nodes. This paper analyses the authentication and access control method using in the Internet of Things presented by Jing et al. (Authentication and Access Control in the Internet of Things. In Proceedings of the 2012 32nd International Conference on Distributed Computing Systems Workshops, Macau, China, 18-21 June 2012, pp. 588-592). According to our analysis, Jing et al.'s protocol is costly in the message exchange and the security assessment is not strong enough for such a protocol. Therefore, we propose improvements to the protocol to fill the discovered weakness gaps. The protocol enhancements facilitate many services to the users such as user anonymity, mutual authentication, and secure session key establishment. Finally, the performance and security analysis show that the improved protocol possesses many advantages against popular attacks, and achieves better efficiency at low communication cost.

Computer and Internet Interventions to Optimize Listening and Learning for People With Hearing Loss: Accessibility, Use, and Adherence.

PubMed

Ferguson, Melanie; Henshaw, Helen

2015-09-01

The aim of this research forum article was to examine accessibility, use, and adherence to computerized and online interventions for people with hearing loss. Four intervention studies of people with hearing loss were examined: 2 auditory training studies, 1 working memory training study, and 1 study of multimedia educational support. A small proportion (approximately 15%) of participants had never used a computer, which may be a barrier to the accessibility of computer and Internet-based interventions. Computer competence was not a factor in intervention use or adherence. Computer skills and Internet access influenced participant preference for the delivery method of the multimedia educational support program. It is important to be aware of current barriers to computer and Internet-delivered interventions for people with hearing loss. However, there is a clear need to develop and future-proof hearing-related applications for online delivery.

An exploratory study into the effect of time-restricted internet access on face-validity, construct validity and reliability of postgraduate knowledge progress testing

PubMed Central

2013-01-01

Background Yearly formative knowledge testing (also known as progress testing) was shown to have a limited construct-validity and reliability in postgraduate medical education. One way to improve construct-validity and reliability is to improve the authenticity of a test. As easily accessible internet has become inseparably linked to daily clinical practice, we hypothesized that allowing internet access for a limited amount of time during the progress test would improve the perception of authenticity (face-validity) of the test, which would in turn improve the construct-validity and reliability of postgraduate progress testing. Methods Postgraduate trainees taking the yearly knowledge progress test were asked to participate in a study where they could access the internet for 30 minutes at the end of a traditional pen and paper test. Before and after the test they were asked to complete a short questionnaire regarding the face-validity of the test. Results Mean test scores increased significantly for all training years. Trainees indicated that the face-validity of the test improved with internet access and that they would like to continue to have internet access during future testing. Internet access did not improve the construct-validity or reliability of the test. Conclusion Improving the face-validity of postgraduate progress testing, by adding the possibility to search the internet for a limited amount of time, positively influences test performance and face-validity. However, it did not change the reliability or the construct-validity of the test. PMID:24195696

Patient access to complex chronic disease records on the Internet.

Bartlett, Cherry; Simpson, Keith; Turner, A Neil

2012-08-06

Access to medical records on the Internet has been reported to be acceptable and popular with patients, although most published evaluations have been of primary care or office-based practice. We tested the feasibility and acceptability of making unscreened results and data from a complex chronic disease pathway (renal medicine) available to patients over the Internet in a project involving more than half of renal units in the UK. Content and presentation of the Renal PatientView (RPV) system was developed with patient groups. It was designed to receive information from multiple local information systems and to require minimal extra work in units. After piloting in 4 centres in 2005 it was made available more widely. Opinions were sought from both patients who enrolled and from those who did not in a paper survey, and from staff in an electronic survey. Anonymous data on enrollment and usage were extracted from the webserver. By mid 2011 over 17,000 patients from 47 of the 75 renal units in the UK had registered. Users had a wide age range (<10 to >90 yrs) but were younger and had more years of education than non-users. They were enthusiastic about the concept, found it easy to use, and 80% felt it gave them a better understanding of their disease. The most common reason for not enrolling was being unaware of the system. A minority of patients had security concerns, and these were reduced after enrolling. Staff responses were also strongly positive. They reported that it aided patient concordance and disease management, and increased the quality of consultations with a neutral effect on consultation length. Neither patient nor staff responses suggested that RPV led to an overall increase in patient anxiety or to an increased burden on renal units beyond the time required to enroll each patient. Patient Internet access to secondary care records concerning a complex chronic disease is feasible and popular, providing an increased sense of empowerment and understanding

This paper considers the distributed access and control problem of massive wireless sensor networks' data access center for the Internet of Things, which is an extension of wireless sensor networks and an element of its topology structure. In the context of the arrival of massive service access requests at a virtual data center, this paper designs a massive sensing data access and control mechanism to improve the access efficiency of service requests and makes full use of the available resources at the data access center for the Internet of things. Firstly, this paper proposes a synergistically distributed buffer access model, which separates the information of resource and location. Secondly, the paper divides the service access requests into multiple virtual groups based on their characteristics and locations using an optimized self-organizing feature map neural network. Furthermore, this paper designs an optimal scheduling algorithm of group migration based on the combination scheme between the artificial bee colony algorithm and chaos searching theory. Finally, the experimental results demonstrate that this mechanism outperforms the existing schemes in terms of enhancing the accessibility of service requests effectively, reducing network delay, and has higher load balancing capacity and higher resource utility rate.

2016-10-27

University students have a higher prevalence rate of depression than the average 18 to 24 year old. Internet self-help has been demonstrated to be effective in decreasing self-rated measures of depression in this population, so it is important to explore the awareness, access and use of such self-help resources in this population. The objective of this study is to explore university students' awareness, access and use of Internet self-help websites for depression and related problems. A total of 2691 university students were surveyed at 3 time points. When asked about browsing behavior, 69.6% (1494/2146) of students reported using the Internet for entertainment. Most students were not familiar with self-help websites for emotional health, although this awareness increased as they completed further assessments. Most students considered user-friendliness, content and interactivity as very important in the design of a self-help website. After being exposed to a self-help website, more students reported visiting websites for emotional health than those who had not been exposed. More students reported visiting self-help websites after becoming aware of such resources. Increased awareness of depression and related treatment resources may increase use of such resources. It is important to increase public awareness with the aim of increasing access to targeted strategies for young people. ©Gordana Culjak, Nick Kowalenko, Christopher Tennant.

The internet is a huge library with avalanche of information resources including healthcare information. There are numerous studies on use of electronic resources by healthcare providers including medical practitioners however, there is a dearth of information on the patterns of use of web-based health information resource by resident doctors in Nigeria. This study therefore investigates the influence of internet accessibility and demographic factors on utilization of web-based health information resources by resident doctors in tertiary healthcare institutions in Nigeria.

On Internet Symmetry and its Impact on Society

Wolff, S. S.

2014-12-01

The end-to-end principle, enunciated by Clark and Saltzer in 1981 enabled an Internet implementation in which there was a symmetry among the network nodes in the sense that no node was architecturally distinguished. Each interface to the network had a unique and accessible address and could communicate on equal terms with any other interface or collection of interfaces. In this egalitarian implementation there was in consequence no architectural distinction between providers and consumers of content - any network node could play either role. As the Internet spread to university campuses, incoming students found 10 megabit Ethernet in the dorm - while their parents at home were still stuck with 56 kilobit dialup. In the two decades bisected by the millenium, this combination of speed and symmetry on campus and beyond led to a panoply of transformational Internet applications such as Internet video conferencing and billion dollar industries like Google, Yahoo!, and Facebook. This talk places early Internet history in a social context, elaborates on the social and economic outcomes, defines"middlebox friction", discusses its erosive consequences, and suggests a solution to restore symmetry to the Internet-at-large.

The insurance mandate of the Affordable Care Act has increased the number of people with health coverage in the United States. There is speculation that this increase in the number of insured could make accessing health care services more difficult. Those who are unable to access care in a timely manner may use the Internet to search for information needed to answer their health questions. The aim was to determine whether difficulty accessing health care services for reasons unrelated to insurance coverage is associated with increased use of the Internet to obtain health information. Survey data from 32,139 adults in the 2011 National Health Interview Study (NHIS) were used in this study. The exposure for this analysis was reporting difficulty accessing health care services or delaying getting care for a reason unrelated to insurance status. To define this exposure, we examined 8 questions that asked whether different access problems occurred during the previous 12 months. The outcome for this analysis, health information technology (HIT) use, was captured by examining 2 questions that asked survey respondents if they used an online health chat room or searched the Internet to obtain health information in the previous 12 months. Several multinomial logistic regressions estimating the odds of using HIT for each reported access difficulty were conducted to accomplish the study objective. Of a survey population of 32,139 adults, more than 15.90% (n=5109) reported experiencing at least one access to care barrier, whereas 3.63% (1168/32,139) reported using online health chat rooms and 43.55% (13,997/32,139) reported searching the Internet for health information. Adults who reported difficulty accessing health care services for reasons unrelated to their health insurance coverage had greater odds of using the Internet to obtain health information. Those who reported delaying getting care because they could not get an appointment soon enough (OR 2.2, 95% CI 1.9-2.5), were

The aim of this study was to test for associations between different aspects of contract and on-board internet access and seafarers' satisfaction and health. Altogether 298 Croatian seafarers, all officers, employed on cargo ships, with a minimum work experience of two years with their current shipping company, participated in an online survey. The questionnaire included sociodemographic items, questions relating to their employment contract and internet access, and measures of job satisfaction, life satisfaction, mental health, and gastrointestinal and cardiovascular symptoms. Their job- and lifesatisfaction levels were higher for shorter duration on board, favourable ratio of work to non-work days, and compliance with the employment contract regarding the changes to work and non-work days. Mental health differed likewise but only in relation to two aspects of the contract: on-board duration and compliance with the contract. The level of gastrointestinal symptoms was lower in cases of shorter on-board duration and compliance with the contract, and in seafarers who have free, unlimited internet access on board. Lower level of cardiovascular symptoms was found in seafarers with free, unlimited internet access on board. Our findings suggest that in promoting satisfaction and health in seafaring, attention should be given to reducing on-board duration, compliance with the contract, and internet accessibility on board.

Helium gas suicides have increased in England and Wales; easy-to-access descriptions of this method on the Internet may have contributed to this rise. To investigate the availability of information on using helium as a method of suicide and trends in searching about this method on the Internet. We analyzed trends in (a) Google searching (2004-2014) and (b) hits on a Wikipedia article describing helium as a method of suicide (2013-2014). We also investigated the extent to which helium was described as a method of suicide on web pages and discussion forums identified via Google. We found no evidence of rises in Internet searching about suicide using helium. News stories about helium suicides were associated with increased search activity. The Wikipedia article may have been temporarily altered to increase awareness of suicide using helium around the time of a celebrity suicide. Approximately one third of the links retrieved using Google searches for suicide methods mentioned helium. Information about helium as a suicide method is readily available on the Internet; the Wikipedia article describing its use was highly accessed following celebrity suicides. Availability of online information about this method may contribute to rises in helium suicides.

Access to the Internet has grown dramatically over the past two decades. Using data from a population-based survey, we aimed to determine the prevalence and predictors of (i) access to the Internet, and (ii) use of the Internet to search for health information. We analyzed data from the 2011-12 California Health Interview Survey (CHIS) and included all individuals 18 years of age and older. Our outcomes were (i) prior use of the Internet, and (ii) use of the Internet to find health or medical information within the past year. We performed survey-weighted logistic regression models on our outcomes to adjust for potentially confounding demographic and socioeconomic factors. Our study included an unweighted and survey-weighted sample of 42,935 and 27,796,484 individuals, respectively. We found that 81.5% of the weighted sample reported having previously used the Internet. Among Internet users, 64.5% stated that they used the Internet within the past year to find health or medical information. Racial/ethnic minorities, older individuals, and those who lived in lower income households and rural areas were less likely to have access to and use the Internet to search for health information. Conversely, English-proficiency and increasing levels of education were positively associated with online health information-seeking. We found that most Californians have access to and use the Internet to search for health information, but still noted a persistent digital divide. Interventions to narrow the divide are needed, otherwise this may lead to a continued widening of existing healthcare disparities. Copyright © 2017 Elsevier B.V. All rights reserved.

Disparities in internet use among orthopedic outpatients.

Walsh, Kenneth P; Rehman, Saqib; Goldhirsh, Jessie

2014-02-01

Internet access has lagged behind for patients with lower incomes and from certain ethnic groups. This study investigated the possible improvement of access to health-related information on the Internet for all patients in an urban outpatient setting, regardless of socioeconomic background. A 28-question survey was completed by 100 orthopedic outpatients evaluating associations between their age, ethnicity, income, or education level and their access to the Internet. The survey also examined how patients used the Internet to obtain information about their medical condition, their privacy concerns when conducting online research, and their use of mobile phones as a primary means of Internet access. The Internet was used by 57% of orthopedic outpatients in this urban setting. Internet access decreased with advancing age but increased with increasing income and education, findings consistent with similar studies. Despite the inability to identify an association between ethnicity and Internet access in this patient population, fewer Latinos (33%) than whites (67%) or African Americans (77%) sought information about their medical condition. Among patients who used a mobile phone as the primary method for online access, 74% were African American or Latino and 26% were white. This difference in mobile phone use for online access suggests that mobile phones have provided ethnic minorities with greater Internet access and thus may have narrowed the digital divide among the races.

The Internet has increasingly become an intrinsic part of everyday life, offering countless possibilities for education, services, recreation, and more. In fact, an entire virtual life within the digitalized World Wide Web is possible and common among many Internet users. Today's psychiatrists must therefore incorporate this dimension of human life into clinical practice, to achieve an adequate assessment of the tools and risks available to the patient. We focus on the Internet as a portal for the trade of and access to substances of abuse. We review the legal regulations that may inform care and standards of practice and analyze the difficulties that arise in assessment and monitoring of the current situation. We consider the potential impact of Internet-based narcotics trade on addiction morbidities and the practice of clinical psychiatry, as well as on the potential legal implications that the forensic expert may face.

Energy challenges in optical access and aggregation networks.

PubMed

Kilper, Daniel C; Rastegarfar, Houman

2016-03-06

Scalability is a critical issue for access and aggregation networks as they must support the growth in both the size of data capacity demands and the multiplicity of access points. The number of connected devices, the Internet of Things, is growing to the tens of billions. Prevailing communication paradigms are reaching physical limitations that make continued growth problematic. Challenges are emerging in electronic and optical systems and energy increasingly plays a central role. With the spectral efficiency of optical systems approaching the Shannon limit, increasing parallelism is required to support higher capacities. For electronic systems, as the density and speed increases, the total system energy, thermal density and energy per bit are moving into regimes that become impractical to support-for example requiring single-chip processor powers above the 100 W limit common today. We examine communication network scaling and energy use from the Internet core down to the computer processor core and consider implications for optical networks. Optical switching in data centres is identified as a potential model from which scalable access and aggregation networks for the future Internet, with the application of integrated photonic devices and intelligent hybrid networking, will emerge. © 2016 The Author(s).

Mobile Edge Computing Empowers Internet of Things

NASA Astrophysics Data System (ADS)

Ansari, Nirwan; Sun, Xiang

In this paper, we propose a Mobile Edge Internet of Things (MEIoT) architecture by leveraging the fiber-wireless access technology, the cloudlet concept, and the software defined networking framework. The MEIoT architecture brings computing and storage resources close to Internet of Things (IoT) devices in order to speed up IoT data sharing and analytics. Specifically, the IoT devices (belonging to the same user) are associated to a specific proxy Virtual Machine (VM) in the nearby cloudlet. The proxy VM stores and analyzes the IoT data (generated by its IoT devices) in real-time. Moreover, we introduce the semantic and social IoT technology in the context of MEIoT to solve the interoperability and inefficient access control problem in the IoT system. In addition, we propose two dynamic proxy VM migration methods to minimize the end-to-end delay between proxy VMs and their IoT devices and to minimize the total on-grid energy consumption of the cloudlets, respectively. Performance of the proposed methods are validated via extensive simulations.

To examine Internet access and interest in receiving nutrition education via social media applications among low-income adults participating in the Supplemental Nutrition Assistance Program Education (SNAP-Ed). A cross-sectional survey was distributed during 25 SNAP-Ed classes throughout the 16 southernmost counties of Illinois. From 188 responses, the majority of participants had Internet access (76%). Among participants aged 18-32 years (n = 51), 92% owned a smartphone with Internet access and 57% indicated that they would use online nutrition education, with most interest in e-mail (41%), Facebook (40%), and text messaging (35%). There was little interest in using blogs, Vine, Twitter, Tumblr, and Pinterest. Overall, 49% of middle-aged adults aged 33-64 years and 87% of seniors aged ≥65 years reported they would not use online nutrition education. Results indicated similar Internet accessibility in southern Illinois among low-income populations compared with national rural rates. Interest in using online nutrition education varied among SNAP-Ed participants according to age. Young adults appeared to be the most captive audience regarding online nutrition education. Results may be useful to agencies implementing SNAP-Ed to supplement current curriculum with online nutrition education for audiences aged ≤32 years.

Accessing files in an Internet: The Jade file system

NASA Technical Reports Server (NTRS)

Peterson, Larry L.; Rao, Herman C.

1991-01-01

Jade is a new distribution file system that provides a uniform way to name and access files in an internet environment. It makes two important contributions. First, Jade is a logical system that integrates a heterogeneous collection of existing file systems, where heterogeneous means that the underlying file systems support different file access protocols. Jade is designed under the restriction that the underlying file system may not be modified. Second, rather than providing a global name space, Jade permits each user to define a private name space. These private name spaces support two novel features: they allow multiple file systems to be mounted under one directory, and they allow one logical name space to mount other logical name spaces. A prototype of the Jade File System was implemented on Sun Workstations running Unix. It consists of interfaces to the Unix file system, the Sun Network File System, the Andrew File System, and FTP. This paper motivates Jade's design, highlights several aspects of its implementation, and illustrates applications that can take advantage of its features.

Background According to the Digital Agenda for Europe, the way children use the Internet and mobile technologies has changed dramatically in the past years. Objective The aims of this study were to: (1) breakdown the modalities of access and use of the Internet by teenagers to assess risks and risky behaviors; and (2) provide scientific data to evaluate and counsel safe use of the Internet and new technologies by teenagers. Methods The study was conducted under the program “Strategies for a Better Internet for Children” started in May 2012 by the European Commission. It represents the main result of the project launched by Telecom Italia, “Anche io ho qualcosa da dire” (I too have something to say), thanks to which many contributions were collected and used to develop a survey. The questionnaire was structured in 45 questions, covering three macro areas of interest. It was approved by the Department Board at University of Magna Graecia’s School of Medicine. After authorization from the regional high school authority, it was administered to all 1534 students (aged 13-19 years) in the city of Catanzaro, Italy. Results The data was broken down into three main groups: (1) describing education and access to the Internet; (2) methods of use and social networking; and (3) perception and evaluation of risk and risky behaviors. Among noteworthy results in the first group, we can mention that the average age of first contact with information technologies was around 9 years. Moreover, 78.87% (1210/1534) of the interviewed students reported having access to a smartphone or a tablet. Among the results of the second group, we found that the most used social networks were Facebook (85.78%, 1316/1534), YouTube (61.14%, 938/1534), and Google+ (51.56%, 791/1534). About 71.31% (1094/1534) of the interviewed teenagers use their name and surname on social networks, and 40.09% (615/1534) of them knew all their Facebook contacts personally.

1994-01-01

This invention provides an integrated, non-volatile, high-speed random access memory. A magnetically switchable ferromagnetic or ferrimagnetic layer is sandwiched between an electrical conductor which provides the ability to magnetize the magnetically switchable layer and a magneto resistive or Hall effect material which allows sensing the magnetic field which emanates from the magnetization of the magnetically switchable layer. By using this integrated three-layer form, the writing process, which is controlled by the conductor, is separated from the storage medium in the magnetic layer and from the readback process which is controlled by the magnetoresistive layer. A circuit for implementing the memory in CMOS or the like is disclosed.

The Internet's potential impact on suicide is of major public health interest as easy online access to pro-suicide information or specific suicide methods may increase suicide risk among vulnerable Internet users. Little is known, however, about users' actual searching and browsing behaviors of online suicide-related information. To investigate what webpages people actually clicked on after searching with suicide-related queries on a search engine and to examine what queries people used to get access to pro-suicide websites. A retrospective observational study was done. We used a web search dataset released by America Online (AOL). The dataset was randomly sampled from all AOL subscribers' web queries between March and May 2006 and generated by 657,000 service subscribers. We found 5526 search queries (0.026%, 5526/21,000,000) that included the keyword "suicide". The 5526 search queries included 1586 different search terms and were generated by 1625 unique subscribers (0.25%, 1625/657,000). Of these queries, 61.38% (3392/5526) were followed by users clicking on a search result. Of these 3392 queries, 1344 (39.62%) webpages were clicked on by 930 unique users but only 1314 of those webpages were accessible during the study period. Each clicked-through webpage was classified into 11 categories. The categories of the most visited webpages were: entertainment (30.13%; 396/1314), scientific information (18.31%; 240/1314), and community resources (14.53%; 191/1314). Among the 1314 accessed webpages, we could identify only two pro-suicide websites. We found that the search terms used to access these sites included "commiting suicide with a gas oven", "hairless goat", "pictures of murder by strangulation", and "photo of a severe burn". A limitation of our study is that the database may be dated and confined to mainly English webpages. Searching or browsing suicide-related or pro-suicide webpages was uncommon, although a small group of users did access websites that contain

As health care costs alarm the nation and the debate increases about the impact of health information technologies, patients are reviewing their medical records increasingly through secure Internet portals. Important questions remain about the impact of portal use on office visits. To evaluate whether use of patient Internet portals to access records is associated with increased primary care utilization. A prospective cohort study. Primary care patients registered on patient Internet portals, within an integrated health system serving rural Pennsylvania and an academic medical center in Boston. Frequency of "clinical portal use" (days/2 mo intervals over 2 y) included secure messaging about clinical issues and viewing laboratory and radiology findings. In year 2, a subset of patients also gained access to their primary care doctor's visit notes. The main outcome was number of primary care office visits. In the first 2 months of the 2-year period, 14% of 44,951 primary care patients engaged in clinical portal use 2 or more days per month, 31% did so 1 day per month, and the remainder had no clinical portal use. Overall, adjusted for age, sex, and chronic conditions, clinical portal use was not associated with subsequent office visits. Fewer than 0.1% of patients engaged in high levels of clinical portal use (31 or more login days in 2 mo) that were associated with 1 or more additional visits in the subsequent 2 months (months 3 and 4). However, the reverse was true: office visits led to subsequent clinical portal use. Similar trends were observed among patients with or without access to visit notes. Patients turn to their portals following visits, but clinical portal use does not contribute to an increase in primary care visits.

From Darwin to Internet at the speed of light

NASA Astrophysics Data System (ADS)

2002-11-01

Data moving around the Internet are like road traffic in that a car can be driven fast down a straight road but has to slow down a great deal when changing direction at a junction. The same thing happens on information highways. Beams of light carry data along fibre-optic cables at very high speeds. When the data arrive at computers, known as servers, the servers redirect them to their final destinations. Presently, you need to convert the light signals into electricity, and that slows everything down. Electrons move at a speed of a few kilometres per second through a circuit, whereas light travels at nearly 300 000 kilometres per second. Integrated optics would leave the data as light and simply channel it through the chip, in the right direction. Scientists call this area integrated optics, referring to the integrated circuit board on which chips are mounted. Instead of miniaturised electronics, however, miniaturised optics are placed on a microchip. ESA has a strategy to enable more sophisticated searches for extra-solar planets in the future. Two planned developments rely on combining the light from such planets in a number of different telescopes. These are the Darwin mission and its precursor, the ESA/ESO Ground-based European Nulling Interferometer Experiment (GENIE). When you combine light beams, you traditionally need moving mirrors and lenses to divert the light beams to where you want them. However, if the system moves, it can break. As Malcolm Fridlund, Project Scientist for Darwin and GENIE says, “To change to integrated optics, which is much smaller and has no moving parts, would be highly desirable.” Desirable certainly, but also difficult. At present, integrated optics is a science that is far behind integrated circuit technology. For this reason, ESA is funding two studies. Astrium has been asked to study a traditional optics approach and Alcatel is investigating an integrated-optics solution. “We shall take the decision on whether GENIE will

We have evaluated the speed margins of write/read 16× digital versatile disc-random access memory (DVD-RAM) test discs using write strategies for 6--16× constant angular velocity (CAV) control. Our approach is to determine the writing parameters for the middle zones by interpolating the zone numbers. Using this interpolation strategy, we successfully obtained overwrite jitter values of less than 8% and bit error rates of less than 10-5 in 6--16× DVD-RAM. Moreover, we confirmed that the speed margins were ± 20% for a 6--16× CAV.

Background Globally many doctors, particularly in low-income countries, have no formal training in using new information to improve their practice. As a first step clinicians must have access to information and so we explored reported access in graduating medical students in Nairobi. Objectives To evaluate final year medical students’ access to new medical information. Methods A cross-sectional survey of fifth (final) year medical students at the University of Nairobi using anonymous, self-administered questionnaires. Findings Questionnaires were distributed to 291 (85%) of a possible 343 students and returned by 152 (44%). Within the previous 12 months half reported accessing some form of new medical information most commonly from books and the internet. However, only a small number reported regular access and specific, new journal articles were rarely accessed. Absence of internet facilities, slow internet speeds and cost were common barriers to access while current training seems rarely to encourage students to seek new information. Conclusion Almost half the students had not accessed any new medical information in their final year in medical school suggesting they are ill prepared for a career that may increasingly demand life-long, self-learning.

Ronquillo, Charlene; Currie, Leanne

2012-01-01

The digital divide is described as the gap between those who do and do not have access to digital information and communications technologies (ICT). ICTs are viewed as an indicator of infrastructure and potential for development, and are a growing platform for health information and services delivery. This study compares the penetration of mobile and broadband Internet technologies by global region from 2000 to 2010. Results illustrate the rapid growth of mobile cellular telephone subscriptions in all global regions with trends suggesting a continued increase. Little to modest gains were made in fixed broadband Internet subscriptions globally. There is a growing popularity of mobile subscriptions with use of data communications, exceeding the numbers of fixed Internet subscriptions. This comparison reveals current strengths that can be built on and highlights the importance of awareness of global trends and using such knowledge to inform design and delivery of ICT-based health services.

Hay, Simon I.; Rogers, David J.; Toomer, Jonathan F.; Snow, Robert W.

2011-01-01

This paper presents the results of an extensive search of the formal and informal literature on annual Plasmodium falciparum entomological inoculation rates (EIR) across Africa from 1980 onwards. It first describes how the annual EIR data were collated, summarized, neo-referenced and staged for public access on the internet. Problems of data standardization, reporting accuracy and the subsequent publishing of information on the internet follow. The review was conducted primarily to investigate the spatial heterogeneity of malaria exposure in Africa and supports the idea of highly heterogeneous risk at the continental, regional and country levels. The implications for malaria control of the significant spatial (and seasonal) variation in exposure to infected mosquito bites are discussed. PMID:10897348

Introducing the Internet.

The benefits to medical practitioners of using the Internet are growing rapidly as the Internet becomes easier to use and ever more biomedical resources become available on line. The Internet is the largest computer network in the world; it is also a virtual community, larger than many nation states, with its own rules of behaviour or "netiquette." There are several types of Internet connection and various ways of acquiring a connection. Once connected, you can obtain, free of charge, programs that allow easy use of the Internet's resources and help on how to use these resources; you can access many of these resources through the hypertext references in the on line version of this series (go to http:@www.bmj.com/bmj/ to reach the electronic version). You can then explore the various methods for accessing, manipulating, or disseminating data on the Internet, such as electronic mail, telnet, file transfer protocol, and the world wide web. Results from a search of the world wide web for information on the rare condition of Recklinghausen's neurofibromatosis illustrate the breadth of medical information available on the Internet.

Online information is a critical resource for evidence-based practice and patient education. This study aimed to establish New Zealand nurses' access and evaluation of online health information in the primary care context using a postal questionnaire survey; there were 630 respondents from a random sample of 931 nurses. The majority of respondents were satisfied with work access to online information (84.5%, n = 501) and searched for online information at least several times a week (57.5%, n = 343). The major barrier to online information seeking was insufficient time, but 68 respondents had no work online information access. The level of nursing qualification was significantly correlated with computer confidence and information quality checking. A range of information evaluation approaches was used. Most nurses in study accessed and evaluated Internet information in contrast to the findings of earlier studies, but there were barriers preventing universal integration into practice. © 2014 Wiley Publishing Asia Pty Ltd.

To determine if patients from a community health clinic have access to computers and/or the Internet and if they believe a computer is useful in their medical care. A convenience sample of 100 subjects, aged 50 years and older, from a community health clinic in Nashville, Tennessee, completed a structured interview and a health literacy assessment. Of the 100 participants, 40 did not have any computer access, 27 had computer but not Internet access, and 33 had Internet access. Participants with computer access (with or without Internet) had higher incomes, higher educational status, and higher literacy status than those without computer access. Of participants reporting current computer use (n = 54), 33% reported never using their computer to look up health and medical information. Of those who "never'' used their computer for this activity, 54% reported they did not have Internet connectivity, whereas 31% reported they did not know how to use the Internet. Although this group of individuals reported that they were comfortable using a computer (77%), they reported being uncomfortable with accessing the Internet (53%). Not only does access to computers and the Internet need to be improved before widespread use by patients, but computer users will need to be instructed on how to navigate the Internet.

Aviation Research and the Internet

NASA Technical Reports Server (NTRS)

Scott, Antoinette M.

1995-01-01

The Internet is a network of networks. It was originally funded by the Defense Advanced Research Projects Agency or DOD/DARPA and evolved in part from the connection of supercomputer sites across the United States. The National Science Foundation (NSF) made the most of their supercomputers by connecting the sites to each other. This made the supercomputers more efficient and now allows scientists, engineers and researchers to access the supercomputers from their own labs and offices. The high speed networks that connect the NSF supercomputers form the backbone of the Internet. The World Wide Web (WWW) is a menu system. It gathers Internet resources from all over the world into a series of screens that appear on your computer. The WWW is also a distributed. The distributed system stores data information on many computers (servers). These servers can go out and get data when you ask for it. Hypermedia is the base of the WWW. One can 'click' on a section and visit other hypermedia (pages). Our approach to demonstrating the importance of aviation research through the Internet began with learning how to put pages on the Internet (on-line) ourselves. We were assigned two aviation companies; Vision Micro Systems Inc. and Innovative Aerodynamic Technologies (IAT). We developed home pages for these SBIR companies. The equipment used to create the pages were the UNIX and Macintosh machines. HTML Supertext software was used to write the pages and the Sharp JX600S scanner to scan the images. As a result, with the use of the UNIX, Macintosh, Sun, PC, and AXIL machines, we were able to present our home pages to over 800,000 visitors.

Caron, S; Berton, J; Beydon, L

2007-08-01

We conducted a study to examine the quality and stability of information available from the Internet on four anaesthesia-related topics. In January 2006, we searched using four key words (porphyria, scleroderma, transfusion risk, and epidural analgesia risk) with five search engines (Google, HotBot, AltaVista, Excite, and Yahoo). We used a published scoring system (NetScoring) to evaluate the first 15 sites identified by each of these 20 searches. We also used a simple four-point scale to assess the first 100 sites in the Google search on one of our four topics ('epidural analgesia risk'). In November 2006, we conducted a second evaluation, using three search engines (Google, AltaVista, and Yahoo) with 14 synonyms for 'epidural analgesia risk'. The five search engines performed similarly. NetScoring scores were lower for transfusion risk (P < 0.001). One or more high-quality sites was identified consistently among the first 15 sites in each search. Quality scored using the simple scale correlated closely with medical content and design by NetScoring and with the number of references (P < 0.05). Synonyms of 'epidural analgesia risk' yielded similar results. The quality of accessed information improved somewhat over the 11 month period with Yahoo and AltaVista, but declined with Google. The Internet is a valuable tool for obtaining medical information, but the quality of websites varies between different topics. A simple rating scale may facilitate the quality scoring on individual websites. Differences in precise search terms used for a given topic did not appear to affect the quality of the information obtained.

This study examined the current technology use of clients in the western Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) region and the preferences these current clients have for using new technologies to interact with WIC. Cross-sectional convenience sample for online survey of WIC clients over 2 months in 2011. A weighted sample of 8,144 participants showed that the majority of WIC clients have access to the Internet using a computer or mobile phone. E-mail, texting, and Facebook were technologies most often used for communication. Significant differences (P < .05) existed between age groups and Facebook use, education level and technology use for education delivery, and education level and use of video chat. Technologies should be considered for addressing WIC clients' needs, including use of text messaging and smartphone apps for appointments, education, and other WIC services; online scheduling and nutrition education; and a stronger Facebook presence for connecting with WIC clients and breastfeeding support.

2017-10-01

Internet-delivered cognitive-behavioral therapy (ICBT) has been established as both efficacious and effective in reducing symptoms of social anxiety. However, most research has been conducted in controlled settings, and little is known regarding the utility of such programs in an open-access format. The present study examined the use, adherence, and effectiveness of Joyable, an open-access, Internet-delivered, coach-supported CBT-based intervention for social anxiety. Participants were 3,384 registered users (Mage [SD] = 29.82 [7.89]; 54% male) that created an account between 2014 and 2016. Characteristics of use, factors related to attrition and adherence, and within-group outcomes were examined. The primary outcome measure was the Social Phobia Inventory. On average, participants remained in the program for 81.02 days (SD = 60.50), during which they completed 12.14 activities (SD = 11.09) and 1.53 exposures (SD = 3.18). About half (57%) had contact with a coach. Full adherence to the program was achieved by 16% of participants, a rate higher than previously published open-access studies of ICBT. Social anxiety symptoms were significantly reduced for participants that engaged in the program, with medium within-group effects from baseline through the cognitive restructuring module (d = 0.63-0.76) and large effects from baseline through the exposure module (d = 1.40-1.83). Response rates were high (72%). Exposures and coach contact were significant predictors of retention and outcome. This open-access online CBT-based program is effective in reducing social anxiety symptoms and has the potential to extend Internet-based mental health services to socially anxious individuals unwilling or unable to seek face-to-face evidence-based therapy.

A federated capability-based access control mechanism for internet of things (IoTs)

NASA Astrophysics Data System (ADS)

Xu, Ronghua; Chen, Yu; Blasch, Erik; Chen, Genshe

2018-05-01

The prevalence of Internet of Things (IoTs) allows heterogeneous embedded smart devices to collaboratively provide intelligent services with or without human intervention. While leveraging the large-scale IoT-based applications like Smart Gird and Smart Cities, IoT also incurs more concerns on privacy and security. Among the top security challenges that IoTs face is that access authorization is critical in resource and information protection over IoTs. Traditional access control approaches, like Access Control Lists (ACL), Role-based Access Control (RBAC) and Attribute-based Access Control (ABAC), are not able to provide a scalable, manageable and efficient mechanisms to meet requirement of IoT systems. The extraordinary large number of nodes, heterogeneity as well as dynamicity, necessitate more fine-grained, lightweight mechanisms for IoT devices. In this paper, a federated capability-based access control (FedCAC) framework is proposed to enable an effective access control processes to devices, services and information in large scale IoT systems. The federated capability delegation mechanism, based on a propagation tree, is illustrated for access permission propagation. An identity-based capability token management strategy is presented, which involves registering, propagation and revocation of the access authorization. Through delegating centralized authorization decision-making policy to local domain delegator, the access authorization process is locally conducted on the service provider that integrates situational awareness (SAW) and customized contextual conditions. Implemented and tested on both resources-constrained devices, like smart sensors and Raspberry PI, and non-resource-constrained devices, like laptops and smart phones, our experimental results demonstrate the feasibility of the proposed FedCAC approach to offer a scalable, lightweight and fine-grained access control solution to IoT systems connected to a system network.

In recent years, the Internet has become one of the most popular sources of health information for users, and pregnant women are no exception. This study aimed to investigate Internet usage among pregnant women for achieving health information on the finding of related studies. This review study was conducted by searching databases such as IranMedex, Magiran, Scientific Information Database, Irandoc, PubMed, Science Direct, Cochrane, Google Scholar, and Scopus in December 2016. Restrictions were placed on publication to within 16 years and language of publication was restricted to English and Persian. Keywords used in the search included information-seeking behavior, information-seeking, information needs, access to information, pregnancy, and pregnant women. This search resulted in 106 related publications and among them sixteen articles met inclusion criteria. This review showed that the use of the Internet by pregnant women was driven by information needs, ease, and speed of access and finding people with the same situation. Fetal development, symptoms, and complications of pregnancy, prenatal tests and nutrition, activities during pregnancy, and stages of delivery were the most often mentioned topics of interest. The benefits of internet use include reduced anxiety, personal support, creating an emotional connection and an increased confidence. Health providers must have sufficient ability for interpreting the achieved information from the Internet and should allocate efficient amount of time for discussing information-seeking manners with pregnant women. Furthermore, they must try to respond to the doubts of pregnant women and provide valid and reliable online educational resources.

Individual differences in memory span: the contribution of rehearsal, access to lexical memory, and output speed.

PubMed

Tehan, G; Lalor, D M

2000-11-01

Rehearsal speed has traditionally been seen to be the prime determinant of individual differences in memory span. Recent studies, in the main using young children as the subject population, have suggested other contributors to span performance, notably contributions from long-term memory and forgetting and retrieval processes occurring during recall. In the current research we explore individual differences in span with respect to measures of rehearsal, output time, and access to lexical memory. We replicate standard short-term phenomena; we show that the variables that influence children's span performance influence adult performance in the same way; and we show that lexical memory access appears to be a more potent source of individual differences in span than either rehearsal speed or output factors.

INTRODUCTION The Internet contains a tremendous amount of unregulated information. Internet use gives adolescents access to a wide variety of information and communication devices, and may be associated with certain risks. OBJECTIVE To provide health care professionals with information on adolescent Internet use and its associated risks. DISCUSSION Ninety-four per cent of Canadian youth surveyed nationwide in 2005 reported having Internet access in their homes. Parents and health care providers need to educate themselves on issues of Internet safety. The divergent means by which adolescents are using the Internet and the inherent risks associated with unsupervised and uneducated use are addressed. Parents and teenagers are provided with tips for safe Internet use, and health care providers are offered sample questions pertaining to adolescent Internet use. SUMMARY A large proportion of adolescents use the Internet daily. Studies examining the risks of online exposure in this age group are evolving. Awareness of the range of applications and information available online will facilitate counselling on appropriate Internet use. PMID:19030361

PubMed

Dezelić, Gjuro

2002-01-01

Internet is one of information technologies marking the transition from the second to the third millennium. The present role and expansion of Internet in medicine and healthcare is reviewed together with the perspective of further development. The beginning and initial expansion of the use of Internet in medicine are described. The World Wide Web (WWW or Web) is recognized as a major reason for this expansion, reaching a state described as a Web-pandemic. The rapid increase of the number of papers dealing with Internet in medical literature is presented as well as the appearance of several journals dedicated to Internet in medicine. First specialized symposia, among them MEDNET world conferences, are noted. First uses of Internet in medicine comprised databases, discussion groups, electronic newsletters, software archives and online public access catalogues. The appearance of the Web has led to a significant improvement of the Internet use in medicine, which is reflected in an exponential increase in the number of publications. It is noted that Internet allows "to do old things in new ways", but also "to do new things". It has become clear that the information revolution evoked by the internet shall leave a deep trace in medicine, as health information has become accessible to the public and ceased to be in exclusive control of health professionals. New medical fields--telemedicine and cybermedicine--appeared as the result of the development and global expansion of information and communication technologies, with cybermedicine dealing more specifically with the use of Internet. The advantages and disadvantages of cybermedicine are discussed, and major problems related to the quality of health information are highlighted. Several systems for quality criteria of health related Web-sites are described, indicating that Websites have to conform with the quality criteria such as transparency and honesty, accountability, privacy and data protection, currency

Editing Wikipedia content by screen reader: easier interaction with the Accessible Rich Internet Applications suite.

PubMed

Buzzi, Marina; Leporini, Barbara

2009-07-01

This study aims to improve Wikipedia usability for the blind and promote the application of standards relating to Web accessibility and usability. First, accessibility and usability of Wikipedia home, search result and edit pages are analysed using the JAWS screen reader; next, suggestions for improving interaction are proposed and a new Wikipedia editing interface built. Most of the improvements were obtained using the Accessible Rich Internet Applications (WAI-ARIA) suite, developed by the World Wide Web Consortium (W3C) within the framework of the Web Accessibility Initiative (WAI). Last, a scenario of use compares interaction of blind people with the original and the modified interfaces. Our study highlights that although all contents are accessible via screen reader, usability issues exist due to the user's difficulties when interacting with the interface. The scenario of use shows how building an editing interface with the W3C WAI-ARIA suite eliminates many obstacles that can prevent blind users from actively contributing to Wikipedia. The modified Wikipedia editing page is simpler to use via a screen reader than the original one because ARIA ensures a page overview, rapid navigation, and total control of what is happening in the interface.

Driver speed selection on high-speed two-lane highways: Comparing speed profiles between uniform and differential speed limits.

PubMed

Russo, Brendan J; Savolainen, Peter T; Gates, Timothy J; Kay, Jonathan J; Frazier, Sterling

2017-07-04

Although a considerable amount of prior research has investigated the impacts of speed limits on traffic safety and operations, much of this research, and nearly all of the research related to differential speed limits, has been specific to limited access freeways. The unique safety and operational issues on highways without access control create difficulty relating the conclusions from prior freeway-related speed limit research to 2-lane highways, particularly research on differential limits due to passing limitations and subsequent queuing. Therefore, the objective of this study was to assess differences in driver speed selection with respect to the posted speed limit on rural 2-lane highways, with a particular emphasis on the differences between uniform and differential speed limits. Data were collected from nearly 59,000 vehicles across 320 sites in Montana and 4 neighboring states. Differences in mean speeds, 85th percentile speeds, and the standard deviation in speeds for free-flowing vehicles were examined across these sites using ordinary least squares regression models. Ultimately, the results of the analysis show that the mean speed, 85th percentile speed, and variability in travel speeds for free-flowing vehicles on 2-lane highways are generally lower at locations with uniform 65 mph speed limits, compared to locations with differential limits of 70 mph for cars and 60 mph for trucks. In addition to posted speed limits, several site characteristics were shown to influence speed selection including shoulder widths, frequency of horizontal curves, percentage of the segment that included no passing zones, and hourly volumes. Differences in vehicle speed characteristics were also observed between states, indicating that speed selection may also be influenced by local factors, such as driver population or enforcement.

2017-01-01

With the increasing convenience of social networking sites and their interconnectedness with human interaction, verbal and image bullying have turned digital, making cyberbullying a new form of bullying attracting the attention of researchers, social workers, and schools. This study focuses on the status quo of attitude toward cyberbullying and cyberbullying behavior, explores associations of attitude toward behavior on cyberbullying behavior in gender and different internet access times. In a cross-sectional survey, adolescents were surveyed through self-report questionnaires, 13,864 respondents were received among 150 high schools in Taiwan. Statistical analyses were performed using structural equation modeling (SEM). The study revealed that attitude toward cyberbullying has a direct effect on cyberbullying behavior; among the greatest direct impact were when students use the Internet during the time frame 10:00–14:00. Parents and schoolteachers pay special attention to students using the Internet during this time frame 10:00–14:00 and give guidance, express care, and help those being bullied to communicate and use the Internet in a correct manner. Among genders, male student attitude toward behavior has a greater effect than those of female students. Both male and female students know what cyberbullying is and have witnessed, heard of, or personally encountered cyberbullying behavior. We recommend students talk to parents or teachers or other people who care to reduce the negative effects of cyberbullying. We hopeful that the conceptualization model presented in this study serves as an activator for researches on attitude toward cyberbullying and cyberbullying behavior, and serves a guide and a call to attract more researches in this area.

The Internet is an increasingly popular medium for delivering educational material. The aim of this study was to determine the attitudes of students and their clinical teachers to the use of the Internet within a dental school in the UK. Questionnaires were distributed to undergraduate dental students in the three clinical years and to all their clinical academic teachers. All students and staff have access to computers and Internet at the university. The majority (72%) of students have access to a computer and 53% also have access to the Internet at home. Of the academic staff, 91% have a computer and 68% have access to the Internet at home. The reasons for use of the Internet differed between staff and students. Whilst equal proportions of students used the Internet for dentistry (38%) and for pleasure (35%), a higher proportion of staff used the Internet more for dentistry (36%) than for pleasure (14%). Students highlighted cost and time as barriers to Internet use, whereas staff lacked confidence in their ability to use the Internet. Less than half (44%) of the students are confident in the accuracy of information from the Internet compared to almost two-thirds (64%) of staff. This study revealed differences in the attitudes of staff and students to the use of Internet as a resource for dentistry. Students are positive to the suggestion that lectures should be presented on the web. Most students (74%) did not see that this would influence attendance at lectures whilst 91% of staff stated that it would decrease lecture attendance. In conclusion, this study revealed differences in the attitudes of staff and students to the use of Internet as a resource for dentistry.

This study was planned to examine the hard and soft form of learning resources available on the internet accessed by the teaching faculty. This study was conducted at the Peshawar Medical College, Peshawar, Pakistan from January 2to April 2017. As the target population was not too large, no sampling technique was employed and census-based approach was adopted. For data collection, the pre-tested questionnaire was distributed among 115 faculty members of both basic and clinical sciences groups with a response rate of 66(57.39%). Data was analysed using SPSS. Among the respondents, 38(57.6%) were males and 28(42.4%) were females. A majority 51 (77.27%) of the respondents used the internet for teaching and research. Library was the most frequently 22 (33.33%) used place for the internet use. Low internet speed, virus on computers and a lack of modern trainings were the major barriers. E-journals, e-books, online databases and theses and dissertations were the major sources consulted by the participants.

The Internet Alert Project: spreading the word about high-risk sexual activities advertised on the Internet.

PubMed

Kachur, R E

2004-11-01

The Internet is an emerging venue for facilitating high-risk sexual behavior; in particular, use of the Internet to seek out sex partners has been shown to be associated with high-risk sexual behaviors, such as an increase in number of sexual partners and an increase in anal sex, which can increase the risk of contracting and transmitting sexually transmitted diseases (STDs) including HIV. In an effort to assist health departments around the country, the Internet Alert Project was developed to provide Centers for Disease Control and Prevention (CDC) project officers and field staff with information about Internet-advertised, high-risk sexual activities in areas that do not have access to sexually explicit material on the Internet. An evaluation was conducted to determine the utility of the Internet Alert Project, its effect on knowledge and awareness of recipients and on public health efforts. Results of the evaluation show the alerts are a useful and valuable tool. The alerts have helped to increase knowledge about sexually-related uses of the Internet and have also driven public health efforts in the field. The results also indicate the need for project areas to access information found on the Internet in order to keep up with the ever-changing behaviors of at-risk populations.

Dart, Jared

2008-08-01

A survey questionnaire was designed and implemented across three different communities to determine the current utilisation, importance, trust and future preference for the internet as a source of health information in three different socioeconomic groups. The following were the key results. Fewer respondents in the low socioeconomic group accessed online health information than the mid-high socioeconomic or university samples. The internet was a much more important source of health information for the university sample. The use of online health information and the importance ascribed to the internet as a source of health information was related to home internet access and the frequency of internet use in all three populations. Most respondents do not bring online health information to their doctor (>70% of those who access online health information). Age alone did not relate to the current use of the internet as a source of health information. Most respondents in all populations did not trust the internet. In all populations the internet was a more preferred source of health information than its current use would suggest, especially among those with home internet access and frequent users of the internet.

The Internet Process Addiction Test: Screening for Addictions to Processes Facilitated by the Internet.

PubMed

Northrup, Jason C; Lapierre, Coady; Kirk, Jeffrey; Rae, Cosette

2015-07-28

The Internet Process Addiction Test (IPAT) was created to screen for potential addictive behaviors that could be facilitated by the internet. The IPAT was created with the mindset that the term "Internet addiction" is structurally problematic, as the Internet is simply the medium that one uses to access various addictive processes. The role of the internet in facilitating addictions, however, cannot be minimized. A new screening tool that effectively directed researchers and clinicians to the specific processes facilitated by the internet would therefore be useful. This study shows that the Internet Process Addiction Test (IPAT) demonstrates good validity and reliability. Four addictive processes were effectively screened for with the IPAT: Online video game playing, online social networking, online sexual activity, and web surfing. Implications for further research and limitations of the study are discussed.

Internet addiction: definition, assessment, epidemiology and clinical management.

PubMed

Shaw, Martha; Black, Donald W

2008-01-01

Internet addiction is characterized by excessive or poorly controlled preoccupations, urges or behaviours regarding computer use and internet access that lead to impairment or distress. The condition has attracted increasing attention in the popular media and among researchers, and this attention has paralleled the growth in computer (and Internet) access. Prevalence estimates vary widely, although a recent random telephone survey of the general US population reported an estimate of 0.3-0.7%. The disorder occurs worldwide, but mainly in countries where computer access and technology are widespread. Clinical samples and a majority of relevant surveys report a male preponderance. Onset is reported to occur in the late 20s or early 30s age group, and there is often a lag of a decade or more from initial to problematic computer usage. Internet addiction has been associated with dimensionally measured depression and indicators of social isolation. Psychiatric co-morbidity is common, particularly mood, anxiety, impulse control and substance use disorders. Aetiology is unknown, but probably involves psychological, neurobiological and cultural factors. There are no evidence-based treatments for internet addiction. Cognitive behavioural approaches may be helpful. There is no proven role for psychotropic medication. Marital and family therapy may help in selected cases, and online self-help books and tapes are available. Lastly, a self-imposed ban on computer use and Internet access may be necessary in some cases.

Palesh, Oxana; Saltzman, Kasey; Koopman, Cheryl

2004-10-01

This study assessed Internet use and attitudes toward illicit use of the Internet in a sample of Russian college students. A sample comprised of 198 students was recruited from a university in Moscow. Each participant completed a survey assessing demographic characteristics, Internet use, and attitudes towards engaging in illicit behaviors over the Internet. About half of the students reported that they used the Internet at least several times a year, with 8% reporting daily use of the Internet. Among Internet users, most reported having Internet access either at home or at a friends' home, and 16 % reported having Internet access from work, school, or a computer center. Among Internet users, the main purpose was for school-related activities (60%), followed by e-mail (55%), entertainment (50%), chatting (24%), and searching for pornography (6%). Although most students thought it was inappropriate to read someone else's e-mail, use someone else's password or credit card information without their permission, or break into someone's computer, many students did endorse those illicit behaviors. Over a fifth of the students reported that they knew hackers. Forty three percent of students agreed that people make too much fuss about watching videos, movies or downloading music on the Internet without paying. Males were more likely than females to report using the Internet for entertainment purposes (p = 0.006) and were more likely to agree that it was okay to break into someone's computer (p = 0.04). The results of this study suggest that these Russian college students predominately use the Internet to help with their schoolwork, to communicate with others, and for entertainment. These results also suggest that interventions may be useful to change attitudes endorsing illicit uses of the Internet.

2013-03-01

The purpose of this study is to investigate the internet use of Turkish adolescents, with a (particular) focus on the risk of Internet addiction. A web-based questionnaire was completed by a total of 4,311 adolescents attending public high schools in grades 9-12, in a small-sized city in western Turkey. Ages ranged from 15 to 19 years, 54 percent were female and 46 percent male. The questionnaire included items on sociodemographic information, Internet usage, and a Turkish version of the Young's Internet Addiction Test. The data were analyzed in SPPS 15.0 program using the t test, the Mann-Whitney U test, correlation and hierarchic regression analysis. The findings show that, regardless of gender, Facebook ranked highest in the classification of students' purpose of Internet use; it was also found that females mainly used the Internet for communication, whereas males were more interested in playing online games and reading newspapers and magazines. The results of hierarchic regression analysis indicated that the significant predictors of the internet addiction were the presence of Internet access at home, gender, and family income levels.

2004-07-01

Rehearsal speed has traditionally been seen to be the prime determinant of individual differences in memory span. Recent studies, in the main using young children as the participant population, have suggested other contributors to span performance. In the present research, we used structural equation modeling to explore, at the construct level, individual differences in immediate serial recall with respect to rehearsal, search, phonological coding, and speed of access to lexical memory. We replicated standard short-term phenomena; we showed that the variables that influence children's span performance influence adult performance in the same way; and we showed that speed of access to lexical memory and facility with phonological codes appear to be more potent sources of individual differences in immediate memory than is either rehearsal speed or search factors.

A fragmentation model of earthquake-like behavior in internet access activity

NASA Astrophysics Data System (ADS)

Paguirigan, Antonino A.; Angco, Marc Jordan G.; Bantang, Johnrob Y.

We present a fragmentation model that generates almost any inverse power-law size distribution, including dual-scaled versions, consistent with the underlying dynamics of systems with earthquake-like behavior. We apply the model to explain the dual-scaled power-law statistics observed in an Internet access dataset that covers more than 32 million requests. The non-Poissonian statistics of the requested data sizes m and the amount of time τ needed for complete processing are consistent with the Gutenberg-Richter-law. Inter-event times δt between subsequent requests are also shown to exhibit power-law distributions consistent with the generalized Omori law. Thus, the dataset is similar to the earthquake data except that two power-law regimes are observed. Using the proposed model, we are able to identify underlying dynamics responsible in generating the observed dual power-law distributions. The model is universal enough for its applicability to any physical and human dynamics that is limited by finite resources such as space, energy, time or opportunity.

Use of the Internet by burns patients, their families and friends.

The Internet has also become an increasingly important source of health-related information. However, with this exponential increase comes the problem that although the volume of information is huge, the quality, accuracy and completeness of the information are questionable, not only in the field of medicine. Previous studies of single medical conditions have suggested that web-based health information has limitations. The aim of this study was to evaluate Internet usage among burned patients and the people accompanying them to the outpatient clinic. A customised questionnaire was created and distributed to all patients and accompanying persons in the adult and paediatric burns clinics. This investigated computer usage, Internet access, usefulness of Internet search and topics searched. Two hundred and ten people completed the questionnaire, a response rate of 83%. Sixty three percent of responders were patients, parents 21.9%, spouses 3.3%, siblings, children and friends the remaining 10.8%. Seventy seven percent of attendees had been injured within the last year, 11% between 1 and 5 years previously, and 12% more than 5 years previously. Seventy four percent had computer and Internet access. Twelve percent had performed a search. Topics searched included skin grafts, scarring and scar management treatments such as pressure garments, silicone gel and massage. This study has shown that computer and Internet access is high, however a very small number actually used the Internet to access further medical information. Patients with longer standing injuries were more likely to access the Internet. Parents of burned children were more frequent Internet users. As more burn units develop their own web sites with information for patients and healthcare providers, it is important to inform patients, family members and friends that such a resource exists. By offering such a service patients are provided with accurate, reliable and easily accessible information which is

To determine whether computer and internet use by persons post spinal cord injury (SCI) is sufficiently prevalent and broad-based to consider using this technology as a long-term treatment modality for patients who have sustained SCI. A multicenter cohort study. Twenty-six past and current U.S. regional Model Spinal Cord Injury Systems. Patients with traumatic SCI (N=2926) with follow-up interviews between 2004 and 2006, conducted at 1 or 5 years postinjury. Not applicable. Results revealed that 69.2% of participants with SCI used a computer; 94.2% of computer users accessed the internet. Among computer users, 19.1% used assistive devices for computer access. Of the internet users, 68.6% went online 5 to 7 days a week. The most frequent use for internet was e-mail (90.5%) and shopping sites (65.8%), followed by health sites (61.1%). We found no statistically significant difference in computer use by sex or level of neurologic injury, and no difference in internet use by level of neurologic injury. Computer and internet access differed significantly by age, with use decreasing as age group increased. The highest computer and internet access rates were seen among participants injured before the age of 18. Computer and internet use varied by race: 76% of white compared with 46% of black subjects were computer users (P<.001), and 95.3% of white respondents who used computers used the internet, compared with 87.6% of black respondents (P<.001). Internet use increased with education level (P<.001): eighty-six percent of participants who did not graduate from high school or receive a degree used the internet, while over 97% of those with a college or associate's degree did. While the internet holds considerable potential as a long-term treatment modality after SCI, limited access to the internet by those who are black, those injured after age 18, and those with less education does reduce its usefulness in the short term for these subgroups.

While problematic Internet use is recognized to be predominant among male adolescents, a female trend is gradually becoming apparent. Our study aimed at investigating the characteristics of female Internet users and distinguishing between the online activities of problematic and regular Internet users' on school days. Data were retrieved from a cross-sectional survey of a representative sample of 3067 8th graders in the canton of Vaud, Switzerland, that completed an online questionnaire in 2012. Only females were included. Based on the Internet addiction test, the sample was divided into regular (RUs) (IAT < 50, n = 1339) and problematic users (PIUs) (IAT ≥ 50, n = 201). Groups were compared regarding sociodemographic variables, online activities, devices used to access the Internet, substance use, and physical activity. Significant variables were included in a backward logistic regression. At the multivariate level, PIUs were more prone to spend time online for leisure activities (odds ratio [OR] 2.38) and to access the Internet through a smartphone (OR 1.79) or tablet (OR 1.84). PIUs were less likely to be physically active (OR 0.86) and more likely to present poor emotional well-being (OR 2.67) and to smoke (OR 1.88). A sizeable percentage of female adolescents are problematic Internet users. When performing a comprehensive biopsychosocial assessment, teenagers owning numerous devices to access the Internet, presenting other health-compromising behaviors or poor emotional well-being should be specifically targeted.

Srinivas, M; Inumpudi, A; Mitra, D K

1998-12-01

The Internet, which has truly united the world, is an extensive network of inter-linked computers storing immense bytes of information that can be accessed by anyone, transcending all barriers. The paediatric surgery Internet consists of exponentially growing material that deals with information specifically for paediatric surgeons and patients of the paediatric age group. We reviewed the methods available to take advantage of this network to enable busy paediatric surgeons to accrue the benefits easily and efficiently rather than be lost in the information ocean by surfing individually. By getting connected to the Internet, the paediatric surgeon gains enormous information that can be useful for patient care. The Internet has revolutionised scientific publications by virtue of its fast and accurate transmission of manuscripts. Paediatric surgeons can send manuscripts by this channel and also access journals, obviating the inherent lag period of communication by post.

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

2017-01-01

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.

Incentive Mechanism for P2P Content Sharing over Heterogenous Access Networks

Sato, Kenichiro; Hashimoto, Ryo; Yoshino, Makoto; Shinkuma, Ryoichi; Takahashi, Tatsuro

In peer-to-peer (P2P) content sharing, users can share their content by contributing their own resources to one another. However, since there is no incentive for contributing contents or resources to others, users may attempt to obtain content without any contribution. To motivate users to contribute their resources to the service, incentive-rewarding mechanisms have been proposed. On the other hand, emerging wireless technologies, such as IEEE 802.11 wireless local area networks, beyond third generation (B3G) cellular networks and mobile WiMAX, provide high-speed Internet access for wireless users. Using these high-speed wireless access, wireless users can use P2P services and share their content with other wireless users and with fixed users. However, this diversification of access networks makes it difficult to appropriately assign rewards to each user according to their contributions. This is because the cost necessary for contribution is different in different access networks. In this paper, we propose a novel incentive-rewarding mechanism called EMOTIVER that can assign rewards to users appropriately. The proposed mechanism uses an external evaluator and interactive learning agents. We also investigate a way of appropriately controlling rewards based on the system service's quality and managing policy.

Because of their social isolation, irregular and unpredictable schedules, limited access to health care, and long periods of travel, long-haul truckers may benefit from the use of mobile health applications on Internet-capable devices. The purpose of this study was to determine Internet access and usage among a sample of long-haul truck drivers. In this cross-sectional study, truck drivers completed a pencil and paper survey with questions on demographics, work and health histories, and Internet access and usage for both personal and job reasons. A total of 106 truck drivers were recruited from trucking industry trade shows, by word of mouth, and directly from trucking companies. Overall, the truck drivers' use of the Internet was limited. Their usage for personal and job-related reasons differed. Social connectivity and access to health and wellness information were important during personal usage time. Job-related Internet use was highly practical, and applied to seeking information for directions and maps, fuel stops and pricing, and communicating with employers or transmitting documents. Age and experience were associated with Internet use. Younger, less-experienced drivers used the Internet more than older, experienced drivers. Targeted mobile health messaging may be a useful tool to inform truck drivers of health conditions and plans, and may provide links to primary care providers needing to monitor or notify drivers of diagnostic results or treatment plans.

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.

Holographic memory for high-density data storage and high-speed pattern recognition

NASA Astrophysics Data System (ADS)

Gu, Claire

2002-09-01

As computers and the internet become faster and faster, more and more information is transmitted, received, and stored everyday. The demand for high density and fast access time data storage is pushing scientists and engineers to explore all possible approaches including magnetic, mechanical, optical, etc. Optical data storage has already demonstrated its potential in the competition against other storage technologies. CD and DVD are showing their advantages in the computer and entertainment market. What motivated the use of optical waves to store and access information is the same as the motivation for optical communication. Light or an optical wave has an enormous capacity (or bandwidth) to carry information because of its short wavelength and parallel nature. In optical storage, there are two types of mechanism, namely localized and holographic memories. What gives the holographic data storage an advantage over localized bit storage is the natural ability to read the stored information in parallel, therefore, meeting the demand for fast access. Another unique feature that makes the holographic data storage attractive is that it is capable of performing associative recall at an incomparable speed. Therefore, volume holographic memory is particularly suitable for high-density data storage and high-speed pattern recognition. In this paper, we review previous works on volume holographic memories and discuss the challenges for this technology to become a reality.

Recent research has examined the context in which preference for specific online activities arises, leading researchers to suggest that excessive Internet users are engaged in specific activities rather than 'generalized' Internet use. The present study aimed to partially replicate and expand these findings by addressing four research questions regarding (i) participants' preferred online activities, (i) possible expected changes in online behavior in light of hypothetical scenarios, (iii) perceived quality of life when access to Internet was not possible, and (iv) how participants with self-diagnosed Internet addiction relate to intensity and frequency of Internet use. A cross-sectional design was adopted using convenience and snowball sampling to recruit participants. A total of 1057 Internet users with ages ranging from 16 to 70 years (M age  = 30 years, SD = 10.84) were recruited online via several English-speaking online forums. Most participants indicated that their preferred activities were (i) accessing general information and news, (ii) social networking, and (iii) using e-mail and/or online chatting. Participants also reported that there would be a significant decrease of their Internet use if access to their preferred activities was restricted. The study also found that 51% of the total sample perceived themselves as being addicted to the Internet, while 14.1% reported that without the Internet their life would be improved. The context in which the Internet is used appears to determine the intensity and the lengths that individuals will go to use this tool. The implications of these findings are further discussed.

For a world-wide, Internet-based study on HIV/AIDS and HIV testing knowledge, we compared the yields, speed and costs of recruitment and participant diversity across free postings on 13 Internet or social media platforms, paid advertising or postings on 3 platforms, and separate free postings and paid advertisements on Facebook. Platforms were compared by study completions (yield), time to completion, completion to enrollment ratios (CERs), and costs/ completion; and by participants’ demographic characteristics, HIV testing history, and health literacy levels. Of the 482 English-speaking participants, Amazon Mechanical Turk yielded the most participants, recruited participants at the fastest rate and had the highest CER (0.78) and lowest costs / completion. Of the 335 Spanish-speaking participants, Facebook yielded the most participants and recruited participants at the fastest rate, although Amazon Mechanical Turk had the highest CER (0.72) and lowest costs/completion. Across platforms participants differed substantially according to their demographic characteristics, HIV testing history and health literay skills. The study results highlight the need for researchers to strongly consider choice of Internet or social media plaforms when conducting Internet-based research. Because of the sample specifications and cost restraints of studies, specific Internet/ social media or participant selection plaforms will be much more effective or appropriate than others.

Internet health information in the patient-provider dialogue.

PubMed

Hong, Traci

2008-10-01

A patient discussing Internet health information with a health care provider (referred to as "patient-provider communication about Internet health information") can contribute positively to health outcomes. Although research has found that once Internet access is achieved, there are no ethnic differences in Internet health information seeking, it is unclear if there are ethnic differences in patient-provider communication about Internet health information. To help fill this gap in the literature, the National Cancer Institute's Health Information National Trends Survey 2005 was analyzed with Stata 9. Two sets of logistic regression analyses were conducted, one for a subsample of Internet users (n = 3,244) and one for a subsample of Internet users who are first-generation immigrants (n = 563). The dependent variable was patient-provider communication about Internet health information, which assessed whether survey participants had discussed online health information with a health care provider. The predictor variables included trust of health care provider, trust of online health information, Internet use, health care coverage, frequency of visits to health care provider, health status, and demographics. Among all Internet users, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. Similarly, among Internet users who are immigrants, Whites had higher levels of patient-provider communication about Internet health information than Blacks and Asians. While the digital divide is narrowing in terms of Internet access, racial differences in patient-provider communication about Internet health information may undermine the potential benefits of the information age.

There is substantial literature on the impact of the mass media on children's and adolescents' health and development. The question of what role new technology plays in the media's influence is now a subject of both review and discussion, particularly regarding health risks and intervention. This article takes a brief look at online usage and the theoretical mechanisms that might make Internet access more problematic in terms of risks, compared with more traditional media such as television and film. One of these risks, known today as cyberbullying or Internet harassment, is scrutinized in detail. Copyright © 2012 Elsevier Inc. All rights reserved.

Some addictions cannot be connected with substance abuse (pathological gambling, video games playing, binge eating, compulsive physical activity, emotional relationship addiction, TV addiction). Since 1995, Internet addiction has been accepted as a clinical entity with profound negative effect on social, familial, educational and economical personal functioning. The diagnosis of Internet addiction could be established if the person spends more than 38 hours per week on the Internet exempting online professional needs. Basic symptoms are the increased number of hours spent in front of the computer along with the Internet use, development of abstinent syndrome if the Internet access is prohibited, sleep inversion, neglect of basic social requirements and personal hygiene, many somatic symptoms developed due to prolonged sitting or monitor watching, dissocial behaviour. In this paper, data about the Internet addiction are presented and a case report of an adolescent with developed Internet addiction.

A client/server system for Internet access to biomedical text/image databanks.

Internet access to mixed text/image databanks is finding application in the medical world. An example is a database of medical X-rays and associated data consisting of demographic, socioeconomic, physician's exam, medical laboratory and other information collected as part of a nationwide health survey conducted by the government. Another example is a collection of digitized cryosection images, CT and MR taken of cadavers as part of the National Library of Medicine's Visible Human Project. In both cases, the challenge is to provide access to both the image and the associated text for a wide end user community to create atlases, conduct epidemiological studies, to develop image-specific algorithms for compression, enhancement and other types of image processing, among many other applications. The databanks mentioned above are being created in prototype form. This paper describes the prototype system developed for the archiving of the data and the client software to enable a broad range of end users to access the archive, retrieve text and image data, display the data and manipulate the images. System design considerations include; data organization in a relational database management system with object-oriented extensions; a hierarchical organization of the image data by different resolution levels for different user classes; client design based on common hardware and software platforms incorporating SQL search capability, X Window, Motif and TAE (a development environment supporting rapid prototyping and management of graphic-oriented user interfaces); potential to include ultra high resolution display monitors as a user option; intuitive user interface paradigm for building complex queries; and contrast enhancement, magnification and mensuration tools for better viewing by the user.

The author constructed a medical image network system using open source software that took security into consideration. This system was enabled for search and browse with a WWW browser, and images were stored in a DICOM server. In order to realize this function, software was developed to fill in the gap between the DICOM protocol and HTTP using PHP language. The transmission speed was evaluated by the difference in protocols between DICOM and HTTP. Furthermore, an attempt was made to evaluate the convenience of medical image access with a personal information terminal via the Internet through the high-speed mobile communication terminal. Results suggested the feasibility of remote diagnosis and application to emergency care.

The impact of the Internet on quality measurement.

Bates, D W; Gawande, A A

2000-01-01

Consumers are eager for information about health. However, their use of such data has been limited to date. When consumers do consider data in making health care choices, they rely more on word-of-mouth reputation than on traditional quality measures, although this information has not necessarily been readily accessible. The Internet changes the exercise of quality measurement in several ways. First, quality information--including reputation--will be more readily available. Second, consumers will increasingly use it. Third, the Internet provides a low-cost, standard platform that will make it vastly easier for providers to collect quality information and pass it on to others. However, major barriers still stand in the way of public access to quality information on the Internet as well as of having that access actually improve patients' care.

Optical Access Networks

Call for Papers: Optical Access Networks With the wide deployment of fiber-optic technology over the past two decades, we have witnessed a tremendous growth of bandwidth capacity in the backbone networks of today's telecommunications infrastructure. However, access networks, which cover the "last-mile" areas and serve numerous residential and small business users, have not been scaled up commensurately. The local subscriber lines for telephone and cable television are still using twisted pairs and coaxial cables. Most residential connections to the Internet are still through dial-up modems operating at a low speed on twisted pairs. As the demand for access bandwidth increases with emerging high-bandwidth applications, such as distance learning, high-definition television (HDTV), and video on demand (VoD), the last-mile access networks have become a bandwidth bottleneck in today's telecommunications infrastructure. To ease this bottleneck, it is imperative to provide sufficient bandwidth capacity in the access networks to open the bottleneck and thus present more opportunities for the provisioning of multiservices. Optical access solutions promise huge bandwidth to service providers and low-cost high-bandwidth services to end users and are therefore widely considered the technology of choice for next-generation access networks. To realize the vision of optical access networks, however, many key issues still need to be addressed, such as network architectures, signaling protocols, and implementation standards. The major challenges lie in the fact that an optical solution must be not only robust, scalable, and flexible, but also implemented at a low cost comparable to that of existing access solutions in order to increase the economic viability of many potential high-bandwidth applications. In recent years, optical access networks have been receiving tremendous attention from both academia and industry. A large number of research activities have been carried out or

Patient portals have shown potential for increasing health care quality and efficiency. Internet access and other factors influencing patient portal use could worsen health disparities. Observational study of adults with 1 or more visits to the outpatient clinics of an urban public health care system from 2012 to 2015. We used mixed effects logistic regression to evaluate the association between broadband internet access and (1) patient portal initiation (whether a patient logged in at least 1 time) and (2) messaging, controlling for demographic and neighborhood characteristics. There were 243 248 adults with 1 or more visits during 2012-2015 and 70 835 (29.1%) initiated portal use. Portal initiation was 34.1% for whites, 23.4% for blacks, and 23.8% for Hispanics, and was lower for Medicaid (26.5%), Medicare (23.4%), and uninsured patients (17.4%) than commercially insured patients (39.3%). In multivariate analysis, both initiation of portal use (odds ratio [OR] = 1.24 per quintile, 95% confidence interval [CI], 1.23-1.24, P  < .0001) and sending messages to providers (OR = 1.15, 95%CI, 1.09-1.14, P  < .0001) were associated with neighborhood broadband internet access. The majority of adults with outpatient visits to a large urban health care system did not use the patient portal, and initiation of use was lower for racial and ethnic minorities, persons of lower socioeconomic status, and those without neighborhood broadband internet access. These results suggest the emergence of a digital divide in patient portal use. Given the scale of investment in patient portals and other internet-dependent health information technologies, efforts are urgently needed to address this growing inequality. © The Author 2017.

The growing use of email and the world wide web (WWW), by the public, academics, and clinicians—as well as the increasing availability of high quality information on the WWW—make a working knowledge of the internet important. Although this article aims to enhance readers' existing use of the internet and medical resources on the WWW, it is also intelligible to someone unfamiliar with the internet. A web browser is one of the central pieces of software in modern computing: it is a window on the WWW, file transfer protocol sites, networked newsgroups, and your own computer's files. Effective use of the internet for professional purposes requires an understanding of the best strategies to search the WWW and the mechanisms for ensuring secure data transfer, as well as a compendium of online resources including journals, textbooks, medical portals, and sites providing high quality patient information. This article summarises these resources, available to incorporate into your web browser as downloadable "Favorites" or "Bookmarks" from www.jnnp.com, where there are also freely accessible hypertext links to the recommended sites.

Bischof-Kastner, Christina; Kuntsche, Emmanuel

2014-01-01

Background Internationally, up to 15.1% of intensive Internet use among adolescents is dysfunctional. To provide a basis for early intervention and preventive measures, understanding the motives behind intensive Internet use is important. Objective This study aims to develop a questionnaire, the Internet Motive Questionnaire for Adolescents (IMQ-A), as a theory-based measurement for identifying the underlying motives for high-risk Internet use. More precisely, the aim was to confirm the 4-factor structure (ie, social, enhancement, coping, and conformity motives) as well as its construct and concurrent validity. Another aim was to identify the motivational differences between high-risk and low-risk Internet users. Methods A sample of 101 German adolescents (female: 52.5%, 53/101; age: mean 15.9, SD 1.3 years) was recruited. High-risk users (n=47) and low-risk users (n=54) were identified based on a screening measure for online addiction behavior in children and adolescents (Online-Suchtverhalten-Skala, OSVK-S).

Internationally, up to 15.1% of intensive Internet use among adolescents is dysfunctional. To provide a basis for early intervention and preventive measures, understanding the motives behind intensive Internet use is important. This study aims to develop a questionnaire, the Internet Motive Questionnaire for Adolescents (IMQ-A), as a theory-based measurement for identifying the underlying motives for high-risk Internet use. More precisely, the aim was to confirm the 4-factor structure (ie, social, enhancement, coping, and conformity motives) as well as its construct and concurrent validity. Another aim was to identify the motivational differences between high-risk and low-risk Internet users. A sample of 101 German adolescents (female: 52.5%, 53/101; age: mean 15.9, SD 1.3 years) was recruited. High-risk users (n=47) and low-risk users (n=54) were identified based on a screening measure for online addiction behavior in children and adolescents (Online-Suchtverhalten-Skala, OSVK-S). Here, "high-risk" Internet use means use that exceeds the level of intensive Internet use (OSVK-S sum score ≥7). The confirmatory factor analysis confirmed the IMQ-A's 4-factor structure. A reliability analysis revealed good internal consistencies of the subscales (.71 up to .86). Moreover, regression analyses confirmed that the enhancement and coping motive groups significantly predicted high-risk Internet consumption and the OSVK-S sum score. A mixed-model ANOVA confirmed that adolescents mainly access the Internet for social motives, followed by enhancement and coping motives, and that high-risk users access the Internet more frequently for coping and enhancement motives than low-risk users. Low-risk users were primarily motivated socially. The IMQ-A enables the assessment of motives related to adolescent Internet use and thus the identification of populations at risk. The questionnaire enables the development of preventive measures or early intervention programs, especially dealing

The Internet is fast gaining recognition as a powerful, low-cost method to deliver health intervention and prevention programs to large numbers of young people across diverse geographic regions. The feasibility and accessibility of Internet-based health interventions in resource-limited settings, where cost-effective interventions are most needed, is unknown. To determine the utility of developing technology-based interventions in resource-limited settings, availability and patterns of usage of the Internet first need to be assessed. The Uganda Media and You Survey was a cross-sectional survey of Internet use among adolescents (ages 12-18 years) in Mbarara, Uganda, a municipality mainly serving a rural population in sub-Saharan Africa. Participants were randomly selected among eligible students attending one of five participating secondary day and boarding schools in Mbarara, Uganda. Of a total of 538 students selected, 93% (500) participated. Of the total respondents, 45% (223) reported ever having used the Internet, 78% (175) of whom reported going online in the previous week. As maternal education increased, so too did the odds of adolescent Internet use. Almost two in five respondents (38% [189]) reported already having used a computer or the Internet to search for health information. Over one-third (35% [173]) had used the computer or Internet to find information about HIV/AIDS, and 20% (102) had looked for sexual health information. Among Internet users, searching for HIV/AIDS information on a computer or online was significantly related to using the Internet weekly, emailing, visiting chat rooms, and playing online games. In contrast, going online at school was inversely related to looking for HIV/AIDS information via technology. If Internet access were free, 66% (330) reported that they would search for information about HIV/AIDS prevention online. Both the desire to use, and the actual use of, the Internet to seek sexual health and HIV/AIDS information is

The Internet is used by young people at risk of self-harm to communicate, find information, and obtain support. We aimed to identify and analyze websites potentially accessed by these young people. Six search terms, relating to self-harm/suicide and depression, were input into four search engines. Websites were analyzed for access, content/purpose, and tone. In all, 314 websites were included in the analysis. Most could be accessed without restriction. Sites accessed by self-harm/suicide search terms were mostly positive or preventive in tone, whereas sites accessed by the term ways to kill yourself tended to have a negative tone. Information about self-harm methods was common with specific advice on how to self-harm in 15.8% of sites, encouragement of self-harm in 7.0%, and evocative images of self-harm/suicide in 20.7%. Advice on how to get help was given in 56.1% of sites. Websites relating to suicide or self-harm are easily accessed. Many sites are potentially helpful. However, a significant proportion of sites are potentially harmful through normalizing or encouraging self-harm. Enquiry regarding Internet use should be routinely included while assessing young people at risk.

Volume server: A scalable high speed and high capacity magnetic tape archive architecture with concurrent multi-host access

NASA Technical Reports Server (NTRS)

Rybczynski, Fred

1993-01-01

A major challenge facing data processing centers today is data management. This includes the storage of large volumes of data and access to it. Current media storage for large data volumes is typically off line and frequently off site in warehouses. Access to data archived in this fashion can be subject to long delays, errors in media selection and retrieval, and even loss of data through misplacement or damage to the media. Similarly, designers responsible for architecting systems capable of continuous high-speed recording of large volumes of digital data are faced with the challenge of identifying technologies and configurations that meet their requirements. Past approaches have tended to evaluate the combination of the fastest tape recorders with the highest capacity tape media and then to compromise technology selection as a consequence of cost. This paper discusses an architecture that addresses both of these challenges and proposes a cost effective solution based on robots, high speed helical scan tape drives, and large-capacity media.

Readability of Internet Information on Hearing: Systematic Literature Review.

Laplante-Lévesque, Ariane; Thorén, Elisabet Sundewall

2015-09-01

This systematic literature review asks the following question: “ What is the readability of Internet information on hearing that people with hearing impairment and their significant others can access in the context of their hearing care?” Searches were completed in three databases: CINAHL, PubMed, and Scopus. Seventy-eight records were identified and systematically screened for eligibility: 8 records were included that contained data on the readability of Internet information on hearing that people with hear ing impairment and their significant others can access in the context of their hearing care. Records reported mean readability levels from 9 to over 14. In other words, people with hearing impairment and their significant others need 9 to 14 years of education to read and understand Internet information on hearing that they access in the context of their hearing care. The poor readability of Internet information on hearing has been well documented; it is time to focus on valid and sustainable initiatives that address this problem.

Computers and the Internet provide researchers with new options in surveying. When using electronic surveys, several practical and methodological issues need to be considered such as whether the majority of the surveyed population has Internet access and whether an e-mail or a Web-based survey is most appropriate. Other important considerations relate to Internet security issues and, in international research, the possibility of language barriers. Despite these challenges, electronic surveys offer a promising alternative to conventional mail surveys.

Accessing Suicide-Related Information on the Internet: A Retrospective Observational Study of Search Behavior

PubMed Central

2013-01-01

Background The Internet’s potential impact on suicide is of major public health interest as easy online access to pro-suicide information or specific suicide methods may increase suicide risk among vulnerable Internet users. Little is known, however, about users’ actual searching and browsing behaviors of online suicide-related information. Objective To investigate what webpages people actually clicked on after searching with suicide-related queries on a search engine and to examine what queries people used to get access to pro-suicide websites. Methods A retrospective observational study was done. We used a web search dataset released by America Online (AOL). The dataset was randomly sampled from all AOL subscribers’ web queries between March and May 2006 and generated by 657,000 service subscribers. Results We found 5526 search queries (0.026%, 5526/21,000,000) that included the keyword "suicide". The 5526 search queries included 1586 different search terms and were generated by 1625 unique subscribers (0.25%, 1625/657,000). Of these queries, 61.38% (3392/5526) were followed by users clicking on a search result. Of these 3392 queries, 1344 (39.62%) webpages were clicked on by 930 unique users but only 1314 of those webpages were accessible during the study period. Each clicked-through webpage was classified into 11 categories. The categories of the most visited webpages were: entertainment (30.13%; 396/1314), scientific information (18.31%; 240/1314), and community resources (14.53%; 191/1314). Among the 1314 accessed webpages, we could identify only two pro-suicide websites. We found that the search terms used to access these sites included “commiting suicide with a gas oven”, “hairless goat”, “pictures of murder by strangulation”, and “photo of a severe burn”. A limitation of our study is that the database may be dated and confined to mainly English webpages. Conclusions Searching or browsing suicide-related or pro-suicide webpages was

Some of the most frequently used online applications are Facebook, WhatsApp, and Twitter. These applications allow individuals to communicate with other users, to share information or pictures, and to stay in contact with friends all over the world. However, a growing number of users suffer from negative consequences due to their excessive use of these applications, which can be referred to as Internet-communication disorder. The frequent use and easy access of these applications may also trigger the individual's fear of missing out on content when not accessing these applications. Using a sample of 270 participants, a structural equation model was analyzed to investigate the role of psychopathological symptoms and the fear of missing out on expectancies towards Internet-communication applications in the development of symptoms of an Internet-communication disorder. The results suggest that psychopathological symptoms predict higher fear of missing out on the individual's Internet-communication applications and higher expectancies to use these applications as a helpful tool to escape from negative feelings. These specific cognitions mediate the effect of psychopathological symptoms on Internet-communication disorder. Our results are in line with the theoretical model by Brand et al. (2016) as they show how Internet-related cognitive bias mediates the relationship between a person's core characteristics (e.g., psychopathological symptoms) and Internet-communication disorder. However, further studies should investigate the role of the fear of missing out as a specific predisposition, as well as specific cognition in the online context.

CHEETAH: circuit-switched high-speed end-to-end transport architecture

2003-10-01

Leveraging the dominance of Ethernet in LANs and SONET/SDH in MANs and WANs, we propose a service called CHEETAH (Circuit-switched High-speed End-to-End Transport ArcHitecture). The service concept is to provide end hosts with high-speed, end-to-end circuit connectivity on a call-by-call shared basis, where a "circuit" consists of Ethernet segments at the ends that are mapped into Ethernet-over-SONET long-distance circuits. This paper focuses on the file-transfer application for such circuits. For this application, the CHEETAH service is proposed as an add-on to the primary Internet access service already in place for enterprise hosts. This allows an end host that is sending a file to first attempt setting up an end-to-end Ethernet/EoS circuit, and if rejected, fall back to the TCP/IP path. If the circuit setup is successful, the end host will enjoy a much shorter file-transfer delay than on the TCP/IP path. To determine the conditions under which an end host with access to the CHEETAH service should attempt circuit setup, we analyze mean file-transfer delays as a function of call blocking probability in the circuit-switched network, probability of packet loss in the IP network, round-trip times, link rates, and so on.

As we get into the Internet of Things era, security and privacy concerns remain as the main obstacles in the development of innovative and valuable services to be exploited by society. Given the Machine-to-Machine (M2M) nature of these emerging scenarios, the application of current privacy-friendly technologies needs to be reconsidered and adapted to be deployed in such global ecosystem. This work proposes different privacy-preserving mechanisms through the application of anonymous credential systems and certificateless public key cryptography. The resulting alternatives are intended to enable an anonymous and accountable access control approach to be deployed on large-scale scenarios, such as Smart Cities. Furthermore, the proposed mechanisms have been deployed on constrained devices, in order to assess their suitability for a secure and privacy-preserving M2M-enabled Internet of Things. PMID:26140349

In this position paper we state four requirements for a Future Internet and sketch our initial concept. The requirements: (1) more comfort, (2) integration of home networks, (3) resources like service clouds in the network, and (4) access anywhere on any machine. Future Internet needs future quality and future comfort. There need to be new possiblities for everyone. Our focus is on higher layers and related to the many overlay proposals. We consider them to run on top of a basic Future Internet core. A new user experience means to include all user devices. Home networks and services should be a fundamental part of the Future Internet. Home networks extend access and allow interaction with the environment. Cloud Computing can provide reliable resources beyond local boundaries. For access anywhere, we also need secure storage for data and profiles in the network, in particular for access with non-personal devices (Internet terminal, ticket machine, ...).

The objective of this study was to assess perceived Internet health literacy of HIV-positive people before and after an Internet health information educational intervention. We developed a 50-min educational intervention on basic computer skills and online health information evaluation. We administered a demographic survey and a validated health literacy survey (eHEALS) at baseline, immediately after, and 3 months the class. Changes in scores between the surveys were analysed. Eighteen HIV-positive participants were included in the final analysis. Before the intervention, most respondents' assessment of their ability to access Internet health information was unfavourable. Post-intervention, the majority of respondents agreed or strongly agreed they were able to access and identify Internet health information resources. The increase in self-assessed skill level was statistically significant for all eight items eHEALS (P < 0.05). Scores for the 3-month follow-up survey remained higher than pre-intervention scores for most items. Providing an interdisciplinary brief introductory Internet health information educational intervention HIV-positive people with baseline low perceived Internet health literacy significantly improves confidence in finding and using Internet health information resources. Studies with larger numbers of participants should be undertaken to determine if brief interventions improve self-care, patient outcomes and use of emergency services. © 2010 The authors.

Increasing prevalence of Internet and new technologies are changing the communication pattern for patients and caregivers across the cancer care continuum. To date, little is known on how cancer survivors in the USA utilize the Internet for health-related purposes. This knowledge is crucial in developing effective communication programs to achieve quality and equitable cancer care. Data from 2003, 2005, and 2008 iterations of the NCI-sponsored Health Information National Trends Survey(HINTS) were analyzed to: (1) compare health-related Internet use (hereafter HRIU) between individuals with and without a cancer diagnosis, (2) report trends, prevalence, and user profiles of HRIU, including support group participation, e-mailing provider, buying medicine online, and cancer information seeking on the Internet. Descriptive analyses and weighted multivariate logistic regression analyses were performed. While Internet penetration is growing over the years across the USA, cancer survivors access the Internet at a lower rate than general population (49.4% to 56.4% vs. 63.1% to 66.3%). Once on the Internet, they are more likely to use it for health-related purposes. Disparities in Internet access persists, as higher likelihood of Internet access is associated with younger age, higher education, non-Hispanic White race/ethnicity, metropolitan residence, and better self-rated health. On the other hand, among Internet-accessing survivors, socio-demographic, and health factors do not play a significant role in determining the pattern of HRIU. The study identifies an increasing trend in HRIU among survivors, though the digital divide remains in Internet access. The findings also point to opportunities for narrowing the divide and using Internet to better serve survivors' needs, as individuals from wide-ranging backgrounds and experiences are equally engaging in health-related activities on the Internet.

Background The internet is an increasingly important tool for physicians, but the extent to which it is used by dermatologists is unknown. We aimed to investigate the utilization of the internet by dermatologists in Saudi Arabia for medical purposes during their daily practice and to clarify the reasons for its use and non-use. Methods A self-administered questionnaire was distributed to all 160 dermatologists attending the National Dermatology conference in 2007. Results A total of 107 questionnaires were completed. Sixty-two percent of respondents had access to the internet in the workplace. The use of the internet to update medical knowledge was reported by 91%. Only 27% had internet access in consultation rooms. The majority of information retrieval occurred outside patient consultation hours (91%). Only 13% reported using the internet during patient consultation. Possible reasons included: lack of access (54%), time pressure (37%), possible interference with the physician-patient relationship (30%), and that use of the internet was too time-consuming (10%). The mean searching time used to solve a clinical problem was 34 ± 3 minutes. Fifty-eight percent used Pubmed; however, 77% of the dermatologists had no training at all in how to use this tool. Conclusion Professional medical use of the internet is widespread among dermatologists in Saudi Arabia. Providing access to the internet in the workplace and training of dermatologists to perform effective electronic searches are badly needed to improve the professional medical use of internet, which is expected to lead to better delivery of patient care.

2009-05-01

The primary purpose of this study was to explore the feasibility and acceptability of using an Internet-based headache diary to obtain acceptable completion rates of daily diaries. Migraine sufferers often perceive that headaches are unpredictable, but 70% have prodromal warning symptoms that may be identified via daily headache diaries. Although diaries are widely used for tracking headaches, Internet-based diaries have not been used previously. A conventional headache diary was formatted for the Internet to collect daily headache data over 4 months using a time-series design.Women between 18 and 55 years who were not pregnant or postmenopausal, and whose headaches met migraine criteria, were recruited primarily via the Internet, completed online consent forms, and were screened via telephone. They completed health history questionnaires and daily diary pages containing scales and open-ended questions,which were saved to a database. Diaries were reviewed and participants were contacted weekly. Completion dates were tracked electronically. Follow-up interviews addressed perceptions about study experiences, and participants received feedback about headache patterns. The majority of participants were recruited from discussion boards and free classified web sites. Of the 101 participants enrolled, 24 withdrew prior to completing 4 months of diary entries. Participants (n = 77) had a mean age of 37.5(7.5) years and were primarily white (82%) and well-educated (93%). They lived in 21 US states, and one in the UK. The majority (68%) completed at least 50% of their diary pages within 24 hours; 75% of all pages were completed within 2 days. At least 64 (83%) kept notes or printed pages when they lacked Internet access. In a follow-up survey (n = 67), 87% would have been willing to continue the diary for another 2 months; 69% had not previously participated in any research. Participants also reported that the study helped them better understand their headache patterns, that

Some of the most up-to-date information on scientific activity is to be found on the Internet; for example, on the websites of academic and other research institutions and in databases of currently funded research studies provided on the websites of funding bodies. Such information can be valuable in suggesting new approaches and techniques that could be applicable in a Three Rs context. However, the Internet is a chaotic medium, not subject to the meticulous classification and organisation of classical information resources. At the same time, Internet search engines do not match the sophistication of search systems used by database hosts. Also, although some offer relatively advanced features, user awareness of these tends to be low. Furthermore, much of the information on the Internet is not accessible to conventional search engines, giving rise to the concept of the "Invisible Web". General strategies and techniques for Internet searching are presented, together with a comparative survey of selected search engines. The question of how the Invisible Web can be accessed is discussed, as well as how to keep up-to-date with Internet content and improve searching skills.

Background 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. Objective The aim of this study was to describe the characteristics of China’s Internet hospitals, and to assess their health service capacity. Methods 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. Results 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). Conclusions Internet hospitals provide convenient outpatient service delivery. However, many of the Internet hospitals are not yet mature and

2009-12-01

The internet has provided us with a high bandwidth, low latency, globally connected network in which to rapidly share realtime data from sensors, reports, and imagery. In addition, the availability of this data is even easier to obtain, consume and analyze. Another aspect of the internet has been the increased approachability of complex systems through lightweight interfaces - with additional complex services able to provide more advanced connections into data services. These analyses and discussions have primarily been siloed within single domains, or kept out of the reach of amateur scientists and interested citizens. However, through more open access to analytical tools and data, experts can collaborate with citizens to gather information, provide interfaces for experimenting and querying results, and help make improved insights and feedback for further investigation. For example, farmers in Uganda are able to use their mobile phones to query, analyze, and be alerted to banana crop disease based on agriculture and climatological data. In the U.S., local groups use online social media sharing sites to gather data on storm-water runoff and stream siltation in order to alert wardens and environmental agencies. This talk will present various web-based geospatial visualization and analysis techniques and tools such as Google Earth and GeoCommons that have emerged that provide for a collaboration between experts of various domains as well as between experts, government, and citizen scientists. Through increased communication and the sharing of data and tools, it is possible to gain broad insight and development of joint, working solutions to a variety of difficult scientific and policy related questions.

Internet2 is a consortium of leading U.S. universities working in partnership with industry and the U.S. government's Next Generation Internet (NGI) initiative to develop a faster, more reliable Internet for research and education including enhanced, high-performance networking services and the advanced applications that are enabled by those services [1]. By facilitating and coordinating the development, deployment, operation, and technology transfer of advanced, network-based applications and network services, Internet2 and NGI are working together to fundamentally change the way scientists, engineers, clinicians, and others work together. [http://www.internet2.edu] The NGI Program has three tracks: research, network testbeds, and applications. The aim of the research track is to promote experimentation with the next generation of network technologies. The network testbed track aims to develop next generation network testbeds to connect universities and federal research institutions at speeds that are sufficient to demonstrate new technologies and support future research. The aim of the applications track is to demonstrate new applications, enabled by the NGI networks, to meet important national goals and missions [2]. [http://www.ngi.gov/] The Internet2/NGI backbone networks, Abilene and vBNS (very high performance Backbone Network Service), provide the basis of collaboration and development for a new breed of advanced medical applications. Academic medical centers leverage the resources available throughout the Internet2 high-performance networking community for high-capacity broadband and selectable quality of service to make effective use of national repositories. The Internet2 Health Sciences Initiative enables a new generation of emerging medical applications whose architecture and development have been restricted by or are beyond the constraints of traditional Internet environments.

Video broadcasting of surgical procedures is an important tool for education, training, and consultation. Current video conferencing systems are expensive and time-consuming and require preplanning. Real-time Internet video is known for its poor quality and relies on the equipment and the speed of the connection. The Internet2, a new high-speed (up to 2,048 Mbps), large bandwidth data network presently connects more than 100 universities and corporations. We have successfully used the Internet2 to broadcast the first real-time, high-quality audio/video program from a live laparoscopic operation to distant points. Video output of the laparoscopic camera and audio from a wireless microphone were broadcast to distant sites using a proprietary, PC-based implementation of H.320 video conferencing over a TCP/IP network connected to the Internet2. The receiving sites participated in two-way, real-time video and audio communications and graded the quality of the signal they received. On August 25, 1998, a laparoscopic Nissen fundoplication was transmitted to Internet2 stations in Colorado, Pennsylvania, and to an Internet station in New York. On September 28 and 29, 1998, we broadcast laparoscopic operations throughout both days to the Internet2 Fall Conference in San Francisco, California. Most recently, on February 24, 1999, we transmitted a laparoscopic Heller myotomy to the Abilene Network Launch Event in Washington, DC. The Internet2 is currently able to provide the bandwidth needed for a turn-key video conferencing system with high-resolution, real-time transmission. The system could be used for a variety of teaching and educational programs for experienced surgeons, residents, and medical students.

Challenges to survey data collection have increased the costs of social research via face-to-face surveys so much that it may become extremely difficult for social scientists to continue using these methods. A key drawback to less expensive Internet-based alternatives is the threat of biased results from coverage errors in survey data. The rise of Internet-enabled smartphones presents an opportunity to re-examine the issue of Internet coverage for surveys and its implications for coverage bias. Two questions (on Internet access and smartphone ownership) were added to the National Survey of Family Growth (NSFG), a U.S. national probability survey of women and men age 15-44, using a continuous sample design. We examine 16 quarters (4 years) of data, from September 2012 to August 2016. Overall, we estimate that 82.9% of the target NSFG population has Internet access, and 81.6% has a smartphone. Combined, this means that about 90.7% of U.S. residents age 15-44 have Internet access, via either traditional devices or a smartphone. We find some evidence of compensatory coverage when looking at key race/ethnicity and age subgroups. For instance, while Black teens (15-18) have the lowest estimated rate of Internet access (81.9%) and the lowest rate of smartphone usage (72.6%), an estimated 88.0% of this subgroup has some form of Internet access. We also examine the socio-demographic correlates of Internet and smartphone coverage, separately and combined, as indicators of technology access in this population. In addition, we look at the effect of differential coverage on key estimates produced by the NSFG, related to fertility, family formation, and sexual activity. While this does not address nonresponse or measurement biases that may differ for alternative modes, our paper has implications for possible coverage biases that may arise when switching to a Web-based mode of data collection, either for follow-up surveys or to replace the main face-to-face data collection

Background For persons living with chronic medical conditions, the Internet can be a powerful tool for health promotion, and allow for immediate access to medical information and social support. However, women living with human immunodeficiency virus (HIV) in the United States face numerous barriers to computer and Internet use. Health behavior change models suggest that the first step towards adopting a new health behavior is to improve attitudes towards that behavior. Objective To develop and pilot test Get+Connected, an intervention to improve computer and Internet attitudes and Internet use among women living with HIV. Methods To develop Get+Connected, we reviewed the extant literature, adapted an existing curriculum, and conducted a focus group with HIV-positive women (n=20) at a community-based organization in the Bronx, New York. Get+Connected was comprised of five weekly sessions covering the following topics: basic computer knowledge and skills, identifying reliable health-related websites, setting up and using email and Facebook accounts, and a final review session. We recruited 12 women to participate in pilot testing. At baseline, we collected data about participants’ sociodemographic information, clinical characteristics, and technology device ownership and use. At baseline, intervention completion, and three months postintervention, we collected data regarding attitudes towards computers and the Internet (Attitudes Towards Computers and the Internet Questionnaire [ATCIQ]; possible scores range from 5-50) as well as frequency of Internet use (composite measure). To examine changes in ATCIQ scores and Internet use over time, we used generalized estimating equations. We also collected qualitative data during intervention delivery. Results Among women in our sample, the median age was 56 years (interquartile range=52-63). All participants were black/African American and/or Latina. Seven participants (7/12, 58%) had a high school diploma (or equivalent

To identify how nurses use the Internet through a survey performed in May 2005. A descriptive cross-sectional study was performed. The information source was a survey sent electronically and through surface mail. The study population consisted of nursing professionals from distinct autonomous regions. The overall response rate was 40% (444 of 1,100). A total of 38.6% (184) of the nursing professionals used the Internet continually, especially men and nursing staff with a high level of English. The 5 most frequent reasons for surfing the net were searching for nursing literature (63% [264]), consulting the web pages of nursing journals (58.6% [256]), seeking information on drugs (55% [230]), seeking protocol manuals (50% [204]), and consulting the web pages of colleges of nursing (48). The behavior of nursing professionals is similar to that found among the general population in the "BBVA Foundation study of the Internet in Spain". Most nursing professionals are women. Male nursing professionals more frequently search for subjects related to nursing theory. Nurses use the Internet to search for nursing literature and consult journals, protocol manuals, and colleges of nursing, as well as to be familiar with the information aimed at patients.

The Internet's effect on personality traits: An important casualty of the "Internet addiction" paradigm.

PubMed

Aboujaoude, Elias

2017-03-01

Background and aims The "Internet addiction" paradigm has been criticized for several shortcomings, including inattention to specific online behaviors, not distinguishing the Internet from other media, insufficient focus on comorbidities, and definitions that do not take into account the constant access now possible. The paradigm's biggest casualty, however, may be that it has diverted attention away from subtle personality changes that seem to occur online, including in users who cannot be considered "addicted" under any definition. Methods A narrative assessment of the literature was conducted, focusing on the Internet's effects on personality traits as revealed in studies of Internet users. Results Impulsivity, narcissism, and aggression are some of the personality traits that seem to be nurtured by the Internet, with possible negative offline consequences. Discussion Ignoring the Internet's subtle effects on personality as we embrace an addiction model that implies severe pathology makes the majority of Internet users feel deceptively immune to the psychological effects of new technologies. It also limits our understanding of the big cultural shifts that are happening as a result. Conclusion The Internet's potentially negative effect on personality, and by extension on society at large, is a fundamental part of online psychology, one well worthy of further investigation.

Background Cancer is one of the most common diseases that patients research on the Internet. The Commission on Cancer (CoC) recommended that Parkland Memorial Hospital (PMH) improve the oncology services website. PMH is Dallas County’s public health care facility, serving a largely uninsured, minority population. Most research regarding patient Internet use has been conducted in insured, Caucasian populations, raising concerns that the needs of PMH patients may not be extrapolated from available data. The PMH Cancer Committee, therefore, adopted a quality improvement initiative to understand patients’ Internet usage. Objective The objective of the study was to obtain and analyze data regarding patients’ Internet usage in order to make targeted improvements to the oncology services section of the institutional website. Methods A task force developed an 11-question survey to ascertain what proportion of our patients have Internet access and use the Internet to obtain medical information as well as determine the specific information sought. Between April 2011 and August 2011, 300 surveys were administered to newly diagnosed cancer patients. Multivariate analyses were performed. Results Of 300 surveys, 291 were included. Minorities, primarily African-American and Hispanic, represented 78.0% (227/291) of patients. Only 37.1% (108/291) of patients had Internet access, most (256/291, 87.9%) having access at home. Younger patients more commonly had Internet access, with a mean age of 47 versus 58 years for those without (P<.001). Education beyond high school was associated with Internet access (P<.001). The most common reason for Internet research was to develop questions for discussion with one’s physician. Patients most frequently sought information regarding cancer treatment options, outcomes, and side effects. Conclusions Less than one-half of PMH oncology patients have Internet access. This is influenced by age, educational level, and ethnicity. Those with

Use of the internet may provide tools and resources for better decision making, yet little is known about the association of internet use with decision making in older persons. We examined this relationship in 661 community-dwelling older persons without dementia from the Rush Memory and Aging Project, an ongoing longitudinal study of aging. Participants were asked to report if they had access to the internet and how frequently they used the internet and email. A 12-item instrument was used to assess financial and healthcare decision making using materials designed to approximate those used in real world settings. Items were summed to yield a total decision making score. Associations were tested via linear regression models adjusted for age, sex, race, education, and a measure of global cognitive function. Secondary models further adjusted for income, depression, loneliness, social networks, social support, chronic medical conditions, instrumental activities of daily living (IADLs), life space size, and health and financial literacy. Interaction terms were used to test for effect modification. Almost 70% of participants had access to the internet, and of those with access, 55% used the internet at least several times a week. Higher frequency of internet use was associated with better financial and healthcare decision making (β = 0.11, p = 0.002). The association persisted in a fully adjusted model (β = 0.08, p = 0.024). Interaction models indicated that higher frequency of internet use attenuated the relationships of older age, poorer cognitive function, and lower levels of health and financial literacy with poorer healthcare and financial decision making. These findings indicate that internet use is associated with better health and financial decision making in older persons. Future research is required to understand whether promoting the use of the internet can produce improvements in healthcare and financial decision making. PMID:24578696

Internet firewalls: questions and answers

Ker, Keith

1996-03-01

As organizations consider connecting to the Internet, the issue of internetwork security becomes more important. There are many tools and components that can be used to secure a network, one of which is a firewall. Modern firewalls offer highly flexible private network security by controlling and monitoring all communications passing into or out of the private network. Specifically designed for security, firewalls become the private network's single point of attack from Internet intruders. Application gateways (or proxies) that have been written to be secure against even the most persistent attacks ensure that only authorized users and services access the private network. One-time passwords prevent intruders from `sniffing' and replaying the usernames and passwords of authorized users to gain access to the private network. Comprehensive logging permits constant and uniform system monitoring. `Address spoofing' attacks are prevented. The private network may use registered or unregistered IP addresses behind the firewall. Firewall-to-firewall encryption establishes a `virtual private network' across the Internet, preventing intruders from eavesdropping on private communications, eliminating the need for costly dedicated lines.

The Role and Implications of the Internet in Healthcare Delivery

NASA Astrophysics Data System (ADS)

Broom, Alex

Drawing on a study of the Internet usage of Australian men with prostate cancer, this chapter investigates how access to information and online support affects men’s experiences of disease and, in particular, the possible implications of Internet-informed patients for the doctor/patient relationship. The data reveal that accessing information and/or support online can have a profound effect on men’s experiences of prostate cancer, providing a method of taking some control over their disease and limiting inhibitions experienced in face-to-face encounters. However, it is also clear that some medical specialists view Internet-informed patients as a challenge to their power within medical encounters and, as a result, employ disciplinary strategies that reinforce traditional patient roles and alienate patients who use the Internet.

In this work we present a novel convolution computing architecture based on metal oxide resistive random access memory (RRAM) to process the image data stored in the RRAM arrays. The proposed image storage architecture shows performances of better speed-device consumption efficiency compared with the previous kernel storage architecture. Further we improve the architecture for a high accuracy and low power computing by utilizing the binary storage and the series resistor. For a 28 × 28 image and 10 kernels with a size of 3 × 3, compared with the previous kernel storage approach, the newly proposed architecture shows excellent performances including: 1) almost 100% accuracy within 20% LRS variation and 90% HRS variation; 2) more than 67 times speed boost; 3) 71.4% energy saving.

Patients with spinal cord injuries and their carers have access to leaflets on Internet that they can use as educational material to complement traditional forms of education. The aim of this study is to evaluate the readability of informative documents in Spanish, obtained from Internet and aimed at patients with spinal cord injuries. A search was made with the Google search engine using the following key words: recommendation, advice, guide, manual, self-care, education and information, adding spinal cord injury, paraplegia and tetraplegia to each of the terms. We analyzed the first 50 results of each search. The readability of the leaflets was studied with the Flesch-Szigriszt index and the INFLESZ scale, both available on the INFLESZ program. Also indicated were year of publication, country and number of authors of the documents obtained. We obtained 16 documents, developed between 2001 and 2011. Readability oscillated between 43.34 (some-what difficult) and 62 (normal), with an average value of 51.56 (somewhat difficult). Only 4 pamphlets (25%) showed a Flesch-Szigriszt index of ≥ 55 (normal). There was no difference in readability by year, authors or country of publication. The readability of 75% of the documents studied was "somewhat difficult" according to the INFLESZ scale. These results coincide with previous studies, in both Spanish and English. If the readability of this type of documents is improved, it will be easier to achieve their educational goal.

Recently published articles have established that a substantial number of cancer patients utilize the Internet to gather information about their respective diagnoses. The challenges for medical providers include understanding the prevalence and characteristics of patients using the Internet, reasons for Internet use, and the effectiveness of currently available websites in providing useful health-related information to patients. Adults with cancer were asked to complete a self-administered, anonymous, 21-item questionnaire upon registration at the Alvin J. Siteman Cancer Center at the Washington University School of Medicine. There were 500 respondents (mean age 58 years (range 18-90), 83% Caucasian and 15% African-American). Three hundred ninety-eight participants (80%) reported access to the Internet, and 315 (63%) reported searching for information about cancer on the Internet. Patients accessing the Internet for cancer information were younger than those who did not (median age 56 vs. 63 years; p < 0.001). Internet usage for cancer information also differed by race (p < 0.0001) and education (p < 0.0001). Among patients who searched the Internet for cancer information, 13.3% of patients had their decisions towards treatments affected or changed, and 11.4% of patients had their choice in physicians affected or changed because of Internet use; 23.5% of patients sought information on clinical trials, and 9.5% of patients were influenced or changed their decision regarding clinical trial enrollment due to Internet information. Approximately two thirds of patients with cancer used the Internet to obtain information about their disease. Factors affecting Internet use for cancer information included age, race, and education. Clinical decisions can be affected by Internet use.

Exponential use of internet has resulted in internet addiction in recent times. Students are particularly at risk because of their unique personal, social, and academic needs. The study was designed to evaluate the prevalence of internet addiction and its determinants among medical students. A cross-sectional study was conducted in 282 medical students with the help of semi-structured questionnaire consisting of questions related to demographic information, information related to internet use, and Young's internet addiction test. We found prevalence of internet addiction among medical students to be 58.87% (mild - 51.42%, moderate -7.45%) and significantly associated factors with internet addiction being male gender, staying in private accommodation, lesser age of first internet use, using mobile for internet access, higher expenditure on internet, staying online for longer time, and using internet for social networking, online videos, and watching website with sexual content. Medical students are vulnerable for internet addiction and efforts should be taken to increase awareness and prevent the problem of internet addiction in them.

2000-03-01

The rapid development of the Internet and the increasing interest in Internet-based solutions has promoted the idea of creating Internet-based health information applications. This will force a change in the role of IC cards in healthcare card systems from a data carrier to an access key medium. At the Medical Informatics Department of Kyoto University Hospital we are developing a smart card patient information project where patient databases are accessed via the Internet. Strong end-to-end data encryption is performed via Secure Socket Layers, transparent to transmit patient information. The smart card is playing the crucial role of access key to the database: user authentication is performed internally without ever revealing the actual key. For easy acceptance by healthcare professionals, the user interface is integrated as a plug-in for two familiar Web browsers, Netscape Navigator and MS Internet Explorer.

Public Access and Open Access: Is There a Difference? | Poster

By Robin Meckley, Contributing Writer, and Tracie Frederick, Guest Writer Open access and public access—are they different concepts or are they the same? What do they mean for the researchers at NCI at Frederick? “Open-access (OA) literature is digital, online, free of charge, and free of most copyright and licensing restrictions. What makes it possible is the Internet and the consent of the author or copyright-holder,” according to an open access website maintained by Peter Suber, director, Harvard Open Access Project.

With this issue, the Journal begins to create an access to the Internet. Our future on the Internet will be achieved systematically, and it will be designed to compliment--add value to--the print Journal. Our Internet connection must be useful to our readers in ways not possible with the print Journal, however, economic considerations cannot be ignored. It would be intellectually and economically unacceptable to produce only a direct copy of theJournal for electronic distribution. The Internet--the information super highway--has been hailed by many as an important information source in the educational process and will become increasingly so in the future. Indeed, there are extant descriptions of apparently innovative uses of modern interactive communications technologies in the education of scientists at the undergraduate level. However, anyone who has attempted to obtain information from the Internet knows that you are as likely to find garbage as you are to find quality information. Webster tells us that garbage is "worthless or nonsensical matter; rubbish; inferior or offensive material; incorrect, meaningless, or unwanted information." An eye for discrimination, which is often a reflection of maturity, is essential when using the current Internet. In other words, because a bit of information appears on the Internet does not ensure its quality. Only in cases where the information sought has its source in a review-oriented process, e.g., from library holdings, can the information on the Internet be trusted. The Internet is fast becoming a "vanity press," where anything can be published with virtually no critique regarding the quality and accuracy of the content. Indeed, it is not necessarily true that the person to whom a bit of information is attributed is the person who posted it. A bit of information on the Internet lies there until someone comes across it and uses it (or links to it), forming a nucleus for further growth. Further growth may center about

For persons living with chronic medical conditions, the Internet can be a powerful tool for health promotion, and allow for immediate access to medical information and social support. However, women living with human immunodeficiency virus (HIV) in the United States face numerous barriers to computer and Internet use. Health behavior change models suggest that the first step towards adopting a new health behavior is to improve attitudes towards that behavior. To develop and pilot test Get+Connected, an intervention to improve computer and Internet attitudes and Internet use among women living with HIV. To develop Get+Connected, we reviewed the extant literature, adapted an existing curriculum, and conducted a focus group with HIV-positive women (n=20) at a community-based organization in the Bronx, New York. Get+Connected was comprised of five weekly sessions covering the following topics: basic computer knowledge and skills, identifying reliable health-related websites, setting up and using email and Facebook accounts, and a final review session. We recruited 12 women to participate in pilot testing. At baseline, we collected data about participants' sociodemographic information, clinical characteristics, and technology device ownership and use. At baseline, intervention completion, and three months postintervention, we collected data regarding attitudes towards computers and the Internet (Attitudes Towards Computers and the Internet Questionnaire [ATCIQ]; possible scores range from 5-50) as well as frequency of Internet use (composite measure). To examine changes in ATCIQ scores and Internet use over time, we used generalized estimating equations. We also collected qualitative data during intervention delivery. Among women in our sample, the median age was 56 years (interquartile range=52-63). All participants were black/African American and/or Latina. Seven participants (7/12, 58%) had a high school diploma (or equivalent) or higher degree. Ten participants (10

Generic Divide and Conquer Internet-Based Computing

The rapid growth of internet-based applications and the proliferation of networking technologies have been transforming traditional commercial application areas as well as computer and computational sciences and engineering. This growth stimulates the exploration of new, internet-oriented software technologies that can open new research and application opportunities not only for the commercial world, but also for the scientific and high -performance computing applications community. The general goal of this research project is to contribute to better understanding of the transition to internet-based high -performance computing and to develop solutions for some of the difficulties of this transition. More specifically, our goal is to design an architecture for generic divide and conquer internet-based computing, to develop a portable implementation of this architecture, to create an example library of high-performance divide-and-conquer computing agents that run on top of this architecture, and to evaluate the performance of these agents. We have been designing an architecture that incorporates a master task-pool server and utilizes satellite computational servers that operate on the Internet in a dynamically changing large configuration of lower-end nodes provided by volunteer contributors. Our designed architecture is intended to be complementary to and accessible from computational grids such as Globus, Legion, and Condor. Grids provide remote access to existing high-end computing resources; in contrast, our goal is to utilize idle processor time of lower-end internet nodes. Our project is focused on a generic divide-and-conquer paradigm and its applications that operate on a loose and ever changing pool of lower-end internet nodes.

To examine the association between sexual health and internet use, including social networking websites such as MySpace and Facebook, among a sample of homeless adolescents at high risk of contracting HIV/AIDS. In 2009, a survey of internet use among 201 homeless adolescents was carried out. Multivariate logistic regression models assessed how patterns of use were associated with engaging in exchange sex (sex for money, drugs, or housing), recent HIV testing, and online partner-seeking behaviors. Among the surveyed adolescents, 96.5% reported internet use. Most youth accessed the internet at public libraries or youth service agencies. Increased time online and recent engagement in exchange sex were both positively associated with online partner-seeking. Youth connected to family members online were less likely to practice exchange sex and more likely to report a recent HIV test. Youth connected to street-based peers online were more likely to practice exchange sex, whereas youth connected to home-based peers online were more likely to report a recent HIV test. Although these data are preliminary, homeless youth need more access to the internet, as access facilitates connecting with family and home-based peers whose presence may reduce sexual risk-taking. Access, however, must be carefully monitored to prevent youth soliciting sex online. Copyright © 2010 Society for Adolescent Health and Medicine. Published by Elsevier Inc. All rights reserved.

Using the Internet in the management of asthma.

Patel, A M

2001-01-01

The ultimate goals of managing asthma are to eliminate death, prevent or promptly treat exacerbations, and maximize the quality of life and health status of patients. Current strategies include appropriate education, trigger control, and timely access to effective pharmacotherapy and follow-up. Internet-based technologies have emerged as potentially powerful tools to enable meaningful communication and proactive partnership in care for various medical conditions. The main types of Internet-based applications for asthma management include remote monitoring and feedback between health professionals and their patients; online education and marketing for either patients or professionals; networking and collaborative research; and administrative oversight through policy making, planning, and decision support. With increased understanding of integrated disease management and the technostructural as well as psychodynamic issues related to Internet use, further refinement and evolution of the Internet and related technologies may drastically improve the way we monitor, educate, treat, and establish policies for this global problem while attending to individual or local community needs. This review presents a conceptual overview of the current challenges and use of the Internet for improving asthma management through timely and tailored education and appropriate access to health care expertise.

Access to medical literature in developing countries is helped by open access publishing and initiatives to allow free access to subscription only journals. The effectiveness of these initiatives in Africa has not been assessed. This study describes awareness, reported use and factors influencing use of on-line medical literature via free access initiatives. Descriptive study in four teaching hospitals in Cameroon, Nigeria, Tanzania and Uganda plus one externally funded research institution in The Gambia. Survey with postgraduate doctors and research scientists to determine Internet access patterns, reported awareness of on-line medical information and free access initiatives; semi structured interviews with a sub-sample of survey participants to explore factors influencing use. In the four African teaching hospitals, 70% of the 305 postgraduate doctors reported textbooks as their main source of information; 66% had used the Internet for health information in the last week. In two hospitals, Internet cafés were the main Internet access point. For researchers at the externally-funded research institution, electronic resources were their main source, and almost all had used the Internet in the last week. Across all 333 respondents, 90% had heard of PubMed, 78% of BMJ on line, 49% the Cochrane Library, 47% HINARI, and 19% BioMedCentral. HINARI use correlates with accessing the Internet on computers located in institutions. Qualitative data suggested there are difficulties logging into HINARI and that sometimes it is librarians that limit access to passwords. Text books remain an important resource for postgraduate doctors in training. Internet use is common, but awareness of free-access initiatives is limited. HINARI and other initiatives could be more effective with strong institutional endorsement and management to promote and ensure access.

Shyness and locus of control as predictors of internet addiction and internet use.

2004-10-01

The new psychological disorder of Internet addiction is fast accruing both popular and professional recognition. Past studies have indicated that some patterns of Internet use are associated with loneliness, shyness, anxiety, depression, and self-consciousness, but there appears to be little consensus about Internet addiction disorder. This exploratory study attempted to examine the potential influences of personality variables, such as shyness and locus of control, online experiences, and demographics on Internet addiction. Data were gathered from a convenient sample using a combination of online and offline methods. The respondents comprised 722 Internet users mostly from the Net-generation. Results indicated that the higher the tendency of one being addicted to the Internet, the shyer the person is, the less faith the person has, the firmer belief the person holds in the irresistible power of others, and the higher trust the person places on chance in determining his or her own course of life. People who are addicted to the Internet make intense and frequent use of it both in terms of days per week and in length of each session, especially for online communication via e-mail, ICQ, chat rooms, newsgroups, and online games. Furthermore, full-time students are more likely to be addicted to the Internet, as they are considered high-risk for problems because of free and unlimited access and flexible time schedules. Implications to help professionals and student affairs policy makers are addressed.

This is the Final Report for the Internet Based Remote Operations Contract, has performed payload operations research support tasks March 1999 through September 1999. These tasks support the GSD goal of developing a secure, inexpensive data, voice, and video mission communications capability between remote payload investigators and the NASA payload operations team in the International Space Station (ISS) era. AZTek has provided feedback from the NASA payload community by utilizing its extensive payload development and operations experience to test and evaluate remote payload operations systems. AZTek has focused on use of the "public Internet" and inexpensive, Commercial-off-the-shelf (COTS) Internet-based tools that would most benefit "small" (e.g., $2 Million or less) payloads and small developers without permanent remote operations facilities. Such projects have limited budgets to support installation and development of high-speed dedicated communications links and high-end, custom ground support equipment and software. The primary conclusions of the study are as follows: (1) The trend of using Internet technology for "live" collaborative applications such as telescience will continue. The GSD-developed data and voice capabilities continued to work well over the "public" Internet during this period. 2. Transmitting multiple voice streams from a voice-conferencing server to a client PC to be mixed and played on the PC is feasible. 3. There are two classes of voice vendors in the market: - Large traditional phone equipment vendors pursuing integration of PSTN with Internet, and Small Internet startups.The key to selecting a vendor will be to find a company sufficiently large and established to provide a base voice-conferencing software product line for the next several years.

The Internet is an inexpensive platform for the investigation of medical questions in case of low prevalence. By accessing www.ao-nailregister.org, every interested participant may participate in the English-language survey of the complications specific to the femoral nail. The address data of the participant, the anonymised key data of the patients and the medical parameters are entered. In real time, these data are checked for plausibility, evaluated and published on the Internet where they are freely accessible immediately. Because of national differences, data acquisition caused considerable difficulties at the beginning. In addition, wrong data were entered because of linguistic or contextual misunderstandings. After having reworked the questionnaire completely, facilitating data input and implementing an automated plausibility check, these difficulties could be cleared. In a next step, the automatic evaluation of the data was implemented. Only very few data still have to be checked for plausibility manually to exclude wrong entries, which cannot be verified by the computer. The effort required for data acquisition and evaluation of the Internet-based femoral nail register was reduced distinctly. The possibility of free international participation as well as the freely accessible representation of the results offers transparency.

Post-migration stressors represent significant obstacle to refugee adjustment, and continued exposure to post-migration stressors can negatively affect mental and physical health. Communities of support maintained over the Internet may provide a sense of constancy and reliability that may insulate against the negative effects of stress. We conducted five focus group interviews with Iraqi and Sudanese refugees to understand how refugees use the Internet to access support in their daily lives. Four trends were observed: (a) Internet use was related to culture of origin, (b) refugees were reluctant to explore online, (c) children served as brokers of online knowledge, and (d) limited Internet access is associated with increased time and financial obligations. This study aims to contribute to theory on Internet-mediated social support and to refugee health by creating smoother pathways to self-sufficiency and allowing refugees to exhibit agency in constructing and maintaining online networks of support. © The Author(s) 2015.

Objective The Internet's potential to bolster health promotion and disease prevention efforts has attracted considerable attention. Existing research leaves two things unclear, however: the prevalence of online health and medical information seeking and the distinguishing characteristics of individuals who seek that information. Design This study seeks to clarify and extend the knowledge base concerning health and medical information use online by profiling adults using Internet medical information (IMI). Secondary analysis of survey data from a large sample (n = 6,119) representative of the Atlanta, GA, area informed this investigation. Measurements Five survey questions were used to assess IMI use and general computer and Internet use during the 30 days before the survey was administered. Five questions were also used to assess respondents' health care system use. Several demographic characteristics were measured. Results Contrary to most prior research, this study found relatively low prevalence of IMI-seeking behavior. Specifically, IMI use was reported by 13.2% of all respondents (n = 6,119) and by 21.1% of respondents with Internet access (n = 3,829). Logistic regression models conducted among respondents accessing the Internet in the previous 30 days revealed that, when controlling for several sociodemographic characteristics, home computer ownership, online time per week, and health care system use are all positively linked with IMI-seeking behavior. Conclusions The data suggest it may be premature to embrace unilaterally the Internet as an effective asset for health promotion and disease prevention efforts that target the public. PMID:19567794

Although not authorised in France, HIV self-tests are easily available online. The authors questioned French-speaking internet-using men who have sex with men (MSM) concerning their access to and use of such tests. Online questionnaire on sex websites and gay and HIV community websites. A multivariate logistic regression for rare events was used to identify factors associated with accessing self-tests. 9169 MSM completed the questionnaire. 2748 (30%) were aware of online self-tests, but only 82 of those aware and not already HIV positive (3.5%) declared having accessed one and only 69 using it. In the multivariate model, living one's sex-life with men in absolute secrecy (odds ratio (OR)=3.90, 95% CI 1.73 to 8.76), knowing of the tests via a sex partner (OR=3.42, CI 1.39 to 8.41) or an internet search engine (OR=2.18, CI 1.26 to 3.74) but not through the general (OR=0.21, CI 0.11 to 0.42) or the gay press (OR=0.34, CI 0.16 to 0.73), having unprotected anal intercourse with a casual partner in the preceding year (OR=1.90, CI 1.17 to 3.06), using self-tests for other diseases (OR=2.66, CI 1.43 to 4.90), using poppers (OR=2.23, CI 1.35 to 3.67) and doping products (OR=3.53, CI 1.55 to 8) in the preceding year, having done a traditional HIV test but not in the preceding year (OR=1.93, CI 1.14 to 3.32), never having had suicidal thoughts (OR=0.54, CI 0.32 to 0.90) and living in the provinces (OR=1.80, CI 1.01 to 3.25) were all independently associated with accessing self-tests. Although readiness to admit use of unauthorised medical products may have influenced results, few MSM aware of the existence of self-tests actually declared having accessed one. Accessing the self-test was independently associated with both living one's sex-life with men in total secrecy and having had unprotected anal intercourse in the last 12 months, indicating that autonomous self-testing may reduce barriers to testing for this vulnerable population.

Call for Papers: Optical Access Networks With the wide deployment of fiber-optic technology over the past two decades, we have witnessed a tremendous growth of bandwidth capacity in the backbone networks of today's telecommunications infrastructure. However, access networks, which cover the "last-mile" areas and serve numerous residential and small business users, have not been scaled up commensurately. The local subscriber lines for telephone and cable television are still using twisted pairs and coaxial cables. Most residential connections to the Internet are still through dial-up modems operating at a low speed on twisted pairs. As the demand for access bandwidth increases with emerging high-bandwidth applications, such as distance learning, high-definition television (HDTV), and video on demand (VoD), the last-mile access networks have become a bandwidth bottleneck in today's telecommunications infrastructure. To ease this bottleneck, it is imperative to provide sufficient bandwidth capacity in the access networks to open the bottleneck and thus present more opportunities for the provisioning of multiservices. Optical access solutions promise huge bandwidth to service providers and low-cost high-bandwidth services to end users and are therefore widely considered the technology of choice for next-generation access networks. To realize the vision of optical access networks, however, many key issues still need to be addressed, such as network architectures, signaling protocols, and implementation standards. The major challenges lie in the fact that an optical solution must be not only robust, scalable, and flexible, but also implemented at a low cost comparable to that of existing access solutions in order to increase the economic viability of many potential high-bandwidth applications. In recent years, optical access networks have been receiving tremendous attention from both academia and industry. A large number of research activities have been carried out or

The Internet goose has laid countless golden eggs, along with a growing number of rotten ones. But it's the rotten ones that now tempt commercial, governmental, and consumer interests to threaten the Internet's uniquely creative power. The expediently selected, almost accidentally generative properties of the Internet - its technical openness, ease of access and mastery, and adaptability - have combined, especially when coupled with those of the PC, to produce an unsurpassed environment for innovative experiment. Those same properties, however, also make the Internet hospitable to various forms of wickedness: hacking, porn, spam, fraud, theft, predation, and attacks on the network itself. As these undesirable phenomena proliferate, business, government, and many users find common cause for locking down Internet and PC architecture in the interests of security and order. PC and Internet security vulnerabilities are a legitimate menace. However, the most likely reactions - if they are not forestalled - will be at least as unfortunate as the security problems themselves. Consider the growing profusion of "tethered appliances" - devices whose functions cannot readily be altered by their owners (think TiVo). Such appliances take Internet innovations and wrap them up in a neat, easy-to-use package, which is good - but only if the Internet and PC can remain sufficiently in the center of the digital ecosystem to produce the next round of innovations and to generate competition. People buy these devices for their convenience or functionality and may appreciate the fact that they are safer to use (they limit the damage users can do through ignorance or carelessness). But the risk is that users, by migrating to such appliances, will unwittingly trade away the future benefits of generativity - a loss that will go unappreciated even as innovation tapers off.

Characteristics of internet addiction/pathological internet use in U.S. university students: a qualitative-method investigation.

Studies have identified high rates and severe consequences of Internet Addiction/Pathological Internet Use (IA/PIU) in university students. However, most research concerning IA/PIU in U.S. university students has been conducted within a quantitative research paradigm, and frequently fails to contextualize the problem of IA/PIU. To address this gap, we conducted an exploratory qualitative study using the focus group approach and examined 27 U.S. university students who self-identified as intensive Internet users, spent more than 25 hours/week on the Internet for non-school or non-work-related activities and who reported Internet-associated health and/or psychosocial problems. Students completed two IA/PIU measures (Young's Diagnostic Questionnaire and the Compulsive Internet Use Scale) and participated in focus groups exploring the natural history of their Internet use; preferred online activities; emotional, interpersonal, and situational triggers for intensive Internet use; and health and/or psychosocial consequences of their Internet overuse. Students' self-reports of Internet overuse problems were consistent with results of standardized measures. Students first accessed the Internet at an average age of 9 (SD = 2.7), and first had a problem with Internet overuse at an average age of 16 (SD = 4.3). Sadness and depression, boredom, and stress were common triggers of intensive Internet use. Social media use was nearly universal and pervasive in participants' lives. Sleep deprivation, academic under-achievement, failure to exercise and to engage in face-to-face social activities, negative affective states, and decreased ability to concentrate were frequently reported consequences of intensive Internet use/Internet overuse. IA/PIU may be an underappreciated problem among U.S. university students and warrants additional research.

Studies have identified high rates and severe consequences of Internet Addiction/Pathological Internet Use (IA/PIU) in university students. However, most research concerning IA/PIU in U.S. university students has been conducted within a quantitative research paradigm, and frequently fails to contextualize the problem of IA/PIU. To address this gap, we conducted an exploratory qualitative study using the focus group approach and examined 27 U.S. university students who self-identified as intensive Internet users, spent more than 25 hours/week on the Internet for non-school or non-work-related activities and who reported Internet-associated health and/or psychosocial problems. Students completed two IA/PIU measures (Young’s Diagnostic Questionnaire and the Compulsive Internet Use Scale) and participated in focus groups exploring the natural history of their Internet use; preferred online activities; emotional, interpersonal, and situational triggers for intensive Internet use; and health and/or psychosocial consequences of their Internet overuse. Students’ self-reports of Internet overuse problems were consistent with results of standardized measures. Students first accessed the Internet at an average age of 9 (SD = 2.7), and first had a problem with Internet overuse at an average age of 16 (SD = 4.3).

Sleep deprivation, academic under-achievement, failure to exercise and to engage in face-to-face social activities, negative affective states, and decreased ability to concentrate were frequently reported consequences of intensive Internet use/Internet overuse.

To progress in the understanding of the user profile and of search trends for health information on the internet. Analyses were performed based on 1,828 individuals who completed an electronic questionnaire available on a very popular health website. At the same time, through the "elite survey" method, 20 specialists were interviewed, aiming at assessing quality control strategies regarding health information disseminated online. A predominance of female users who research information for themselves (= 90%), who consider the internet one of their main sources of health information (86%), and who spend from 5 to 35 hours online every week (62%) was verified. High reliability is assigned to information from specialists (76%), and low reliability to television, radio, or blogs (14%). It can be concluded that the internet is proving to be a major source of health information for the population, and that website certification is a strategy to be contemplated to improve the quality of information and to promote public health.

In recent years there has been interest in websites as a means of increasing access to free chlamydia tests through the National Chlamydia Screening Programme (NCSP) in England. We aimed to describe and evaluate online access to chlamydia testing within the NCSP. We analysed NCSP chlamydia testing data (2006-2010) for 15-24 year olds from the 71/95 programme areas in England where site codes were available to identify tests ordered through the internet. The characteristics of people using online testing services in 2010 were compared with those testing in general practice (GP) or community sexual and reproductive health (SRH) services. We evaluated 58 websites offering free chlamydia tests through the NCSP, and 32 offering kits on a commercial basis for signposting to clinical service and health promotion advice offered. Between 2006 and 2010, 5% of all tests in the included programme areas were accessed through the internet. The number of internet tests increased from 18 (<1% of all tests) in 2006 to 59,750 in 2010 (6% of all NCSP tests). In 2010 the proportion of NCSP tests accessed online by programme area ranged from <1% to 38%. The proportion of tests with a positive result on the internet was higher than tests from general practice and comparable to those from community SRH services (internet 7.6%; GP 5.6%; Community SRH 8.2%). A higher proportion of people accessing online testing were male, aged 20-24 and reported >1 sexual partner in the past year. Provision of sexual health information and appropriate signposting for those in need of clinical services varied between websites. Service provision within the NCSP was fragmented with multiple providers serving specific geographical catchment areas. Internet testing reaches a population with a relatively high risk of chlamydia infection and appears acceptable to young men, a group that has been difficult to engage with chlamydia testing. In order to maximise the potential benefit of these services, websites

BACKGROUND: The explosion of projects utilizing the World Wide Web in the home environment offer a select group of patients a tremendous tool for information management and health-related support. However, many patients do not have ready access to the Internet in their homes. For these patients, Internet TV set-top devices may provide a low cost alternative to PC-based web browsers. METHODS: As a part of a larger descriptive study providing adolescents with access to an on-line support group, we investigated the feasibility of using an Internet TV set-top device for those patients in need of Internet access. RESULTS: Although the devices required some configuration before being installed in the home environment, they required a minimum of support and were well accepted by these patients. However, these patients used the Internet less frequently than their peers with home personal computers--most likely due to a lack of easy availability of the telephone or television at all times. CONCLUSION: Internet TV set-top devices represent a feasible alternative access to the World Wide Web for some patients. Any attempt to use these devices should, however, be coupled with education to all family members, and an attempt at providing a dedicated television and phone line.

OBJECTIVES This study aimed to explore the use of information and communications technology (ICT) in undergraduate medical education in developing countries. METHODS Educators (deans and heads of medical education) in English-speaking countries across Africa were sent a questionnaire to establish the current state of ICT at medical schools. Non-respondents were contacted firstly by e-mail, subsequently by two postal mailings at 3-month intervals, and finally by telephone. Main outcome measures included cross-sectional data about the availability of computers, specifications, Internet connection speeds, use of ICT by students, and teaching of ICT and computerised research skills, presented by country or region. RESULTS The mean computer : student ratio was 0.123. Internet speeds were rated as 'slow' or 'very slow' on a 5-point Likert scale by 25.0% of respondents overall, but by 58.3% in East Africa and 33.3% in West Africa (including Cameroon). Mean estimates showed that campus computers more commonly supported CD-ROM (91.4%) and sound (87.3%) than DVD-ROM (48.1%) and Internet (72.5%). The teaching of ICT and computerised research skills, and the use of computers by medical students for research, assignments and personal projects were common. CONCLUSIONS It is clear that ICT infrastructure in Africa lags behind that in other regions. Poor download speeds limit the potential of Internet resources (especially videos, sound and other large downloads) to benefit students, particularly in East and West (including Cameroon) Africa. CD-ROM capability is more widely available, but has not yet gained momentum as a means of distributing materials. Despite infrastructure limitations, ICT is already being used and there is enthusiasm for developing this further. Priority should be given to developing partnerships to improve ICT infrastructure and maximise the potential of existing technology.

Design of a memory-access controller with 3.71-times-enhanced energy efficiency for Internet-of-Things-oriented nonvolatile microcontroller unit

NASA Astrophysics Data System (ADS)

Natsui, Masanori; Hanyu, Takahiro

2018-04-01

In realizing a nonvolatile microcontroller unit (MCU) for sensor nodes in Internet-of-Things (IoT) applications, it is important to solve the data-transfer bottleneck between the central processing unit (CPU) and the nonvolatile memory constituting the MCU. As one circuit-oriented approach to solving this problem, we propose a memory access minimization technique for magnetoresistive-random-access-memory (MRAM)-embedded nonvolatile MCUs. In addition to multiplexing and prefetching of memory access, the proposed technique realizes efficient instruction fetch by eliminating redundant memory access while considering the code length of the instruction to be fetched and the transition of the memory address to be accessed. As a result, the performance of the MCU can be improved while relaxing the performance requirement for the embedded MRAM, and compact and low-power implementation can be performed as compared with the conventional cache-based one. Through the evaluation using a system consisting of a general purpose 32-bit CPU and embedded MRAM, it is demonstrated that the proposed technique increases the peak efficiency of the system up to 3.71 times, while a 2.29-fold area reduction is achieved compared with the cache-based one.

The Veterans Health Administration has developed My HealtheVet (MHV), a Web-based portal that links veterans to their care in the veteran affairs (VA) system. The objective of this study was to measure diabetic veterans' access to and use of the Internet, and their interest in using MHV to help manage their diabetes. Cross-sectional mailed survey of 201 patients with type 2 diabetes and hemoglobin A(1c) > 8.0% receiving primary care at any of five primary care clinic sites affiliated with a VA tertiary care facility. Main measures included Internet usage, access, and attitudes; computer skills; interest in using the Internet; awareness of and attitudes toward MHV; demographics; and socioeconomic status. A majority of respondents reported having access to the Internet at home. Nearly half of all respondents had searched online for information about diabetes, including some who did not have home Internet access. More than a third obtained "some" or "a lot" of their health-related information online. Forty-one percent reported being "very interested" in using MHV to help track their home blood glucose readings, a third of whom did not have home Internet access. Factors associated with being "very interested" were as follows: having access to the Internet at home (p < 0.001), "a lot/some" trust in the Internet as a source of health information (p = 0.002), lower age (p = 0.03), and some college (p = 0.04). Neither race (p = 0.44) nor income (p = 0.25) was significantly associated with interest in MHV. This study found that a diverse sample of older VA patients with sub-optimally controlled diabetes had a level of familiarity with and access to the Internet comparable to an age-matched national sample. In addition, there was a high degree of interest in using the Internet to help manage their diabetes.

Wu, Jiin-Chuan (Inventor); Stadler, Henry L. (Inventor); Katti, Romney R. (Inventor)

1992-01-01

A high speed read MRAM memory element is configured from a sandwich of magnetizable, ferromagnetic film surrounding a magneto-resistive film which may be ferromagnetic or not. One outer ferromagnetic film has a higher coercive force than the other and therefore remains magnetized in one sense while the other may be switched in sense by a switching magnetic field. The magneto-resistive film is therefore sensitive to the amplitude of the resultant field between the outer ferromagnetic films and may be constructed of a high resistivity, high magneto-resistive material capable of higher sensing currents. This permits higher read voltages and therefore faster read operations. Alternate embodiments with perpendicular anisotropy, and in-plane anisotropy are shown, including an embodiment which uses high permeability guides to direct the closing flux path through the magneto-resistive material. High density, high speed, radiation hard, memory matrices may be constructed from these memory elements.

The Internet as an emerging patient education tool among African American men with prostate cancer: an exploratory study.

Wallington, Sherrie Flynt

2008-06-01

The lives of African American men with prostate cancer are greatly influenced by the information available to them, some of which is accessed on the Internet. Research indicates that the Internet can enhance consumer health knowledge but has not reached socioeconomic groups at highest risk for health disparities, such as African American men with prostate cancer. In this study, focus groups were used to explore the perceptions and uses of the Internet as a patient education tool among 39 African American men aged 39 years and older with diverse socioeconomic backgrounds. Nineteen (49%) participants reported using the Internet, 15 (38%) reported no use but indicated it was used on their behalf, and 5 (13%) reported no use and no use on their behalf. The findings revealed varying degrees of Internet use for information and social support. Prostate cancer diagnosis, poor patient-doctor communications, and accessibility influenced Internet use. Accessibility related more to lack of ease and familiarity with Internet use than lack of computer access. With training and awareness, the Internet has potential as a patient education tool among African American men with prostate cancer.

Compared to traditional research methods, using the Internet to conduct research offers a number of advantages to the researcher, which include increased access to sensitive issues and vulnerable / hidden populations; decreased data entry time requirements; and enhanced data accuracy. However, Internet research also presents certain challenges to the researcher. In this article, the advantages and challenges of Internet research methods are discussed in four principle issue areas: (a) recruitment, (b) data quality, (c) practicality, and (d) ethics. Nursing researchers can overcome problems related to sampling bias and data truthfulness using creative methods; resolve technical problems through collaboration with other disciplines; and protect participant's privacy, confidentiality and data security by maintaining a high level of vigilance. Once such issues have been satisfactorily addressed, the Internet should open a new window for Taiwan nursing research.

Interactive browsing of 3D environment over the Internet

NASA Astrophysics Data System (ADS)

Zhang, Cha; Li, Jin

2000-12-01

In this paper, we describe a system for wandering in a realistic environment over the Internet. The environment is captured by the concentric mosaic, compressed via the reference block coder (RBC), and accessed and delivered over the Internet through the virtual media (Vmedia) access protocol. Capturing the environment through the concentric mosaic is easy. We mount a camera at the end of a level beam, and shoot images as the beam rotates. The huge dataset of the concentric mosaic is then compressed through the RBC, which is specifically designed for both high compression efficiency and just-in-time (JIT) rendering. Through the JIT rendering function, only a portion of the RBC bitstream is accessed, decoded and rendered for each virtual view. A multimedia communication protocol -- the Vmedia protocol, is then proposed to deliver the compressed concentric mosaic data over the Internet. Only the bitstream segments corresponding to the current view are streamed over the Internet. Moreover, the delivered bitstream segments are managed by a local Vmedia cache so that frequently used bitstream segments need not be streamed over the Internet repeatedly, and the Vmedia is able to handle a RBC bitstream larger than its memory capacity. A Vmedia concentric mosaic interactive browser is developed where the user can freely wander in a realistic environment, e.g., rotate around, walk forward/backward and sidestep, even under a tight bandwidth of 33.6 kbps.

Remote sensing education and Internet/World Wide Web technology

Remote sensing education is increasingly in demand across academic and professional disciplines. Meanwhile, Internet technology and the World Wide Web (WWW) are being more frequently employed as teaching tools in remote sensing and other disciplines. The current wealth of information on the Internet and World Wide Web must be distilled, nonetheless, to be useful in remote sensing education. An extensive literature base is developing on the WWW as a tool in education and in teaching remote sensing. This literature reveals benefits and limitations of the WWW, and can guide its implementation. Among the most beneficial aspects of the Web are increased access to remote sensing expertise regardless of geographic location, increased access to current material, and access to extensive archives of satellite imagery and aerial photography. As with other teaching innovations, using the WWW/Internet may well mean more work, not less, for teachers, at least at the stage of early adoption. Also, information posted on Web sites is not always accurate. Development stages of this technology range from on-line posting of syllabi and lecture notes to on-line laboratory exercises and animated landscape flyovers and on-line image processing. The advantages of WWW/Internet technology may likely outweigh the costs of implementing it as a teaching tool.

PCASSO: a design for secure communication of personal health information via the internet.

Baker, D B; Masys, D R

1999-05-01

The Internet holds both promise and peril for the communications of person-identifiable health information. Because of technical features designed to promote accessibility and interoperability rather than security, Internet addressing conventions and transport protocols are vulnerable to compromise by malicious persons and programs. In addition, most commonly used personal computer (PC) operating systems currently lack the hardware-based system software protection and process isolation that are essential for ensuring the integrity of trusted applications. Security approaches designed for electronic commerce, that trade known security weaknesses for limited financial liability, are not sufficient for personal health data, where the personal damage caused by unintentional disclosure may be far more serious. To overcome these obstacles, we are developing and evaluating an Internet-based communications system called PCASSO (Patient-centered access to secure systems online) that applies state of the art security to health information. PCASSO includes role-based access control, multi-level security, strong device and user authentication, session-specific encryption and audit trails. Unlike Internet-based electronic commerce 'solutions,' PCASSO secures data end-to-end: in the server; in the data repository; across the network; and on the client. PCASSO is designed to give patients as well as providers access to personal health records via the Internet.

The rapid and dramatic incursion of the Internet and social networks in everyday life has revolutionised the methods of exchanging data. Web 2.0 represents the evolution of the Internet as we know it. Internet users are no longer passive receivers, and actively participate in the delivery of information. Medical education cannot evade this process. Increasingly, students are using tablets and smartphones to instantly retrieve medical information on the web or are exchanging materials on their Facebook pages. Medical educators cannot ignore this continuing revolution, and therefore the traditional academic schedules and didactic schemes should be questioned. Analysing opinions collected from medical students regarding old and new teaching methods and tools has become mandatory, with a view towards renovating the process of medical education. A cross-sectional online survey was created with Google® docs and administrated to all students of our medical school. Students were asked to express their opinion on their favourite teaching methods, learning tools, Internet websites and Internet delivery devices. Data analysis was performed using spss. The online survey was completed by 368 students. Although textbooks remain a cornerstone for training, students also identified Internet websites, multimedia non-online material, such as the Encyclopaedia on CD-ROM, and other non-online computer resources as being useful. The Internet represented an important aid to support students' learning needs, but textbooks are still their resource of choice. Among the websites noted, Google and Wikipedia significantly surpassed the peer-reviewed medical databases, and access to the Internet was primarily through personal computers in preference to other Internet access devices, such as mobile phones and tablet computers. Increasingly, students are using tablets and smartphones to instantly retrieve medical information. © 2014 John Wiley & Sons Ltd.

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.

The Internet has been exploited successfully in the past as a medium for behavioral research. This paper presents a series of studies designed to assess Internet-based measures of drivers' risk-taking behavior. First, we compared responses from an Internet sample with a traditional pencil-and-paper sample using established questionnaire measures of risk taking. No significant differences were found. Second, we assessed the validity of new Internet-based instruments, involving photographs and photographic animations, that measured speed, gap acceptance, and passing. Responses were found to reflect known demographic patterns of actual behavior to some degree. Also, a roadside survey of speeds was carried out at the locations depicted in the photographic measure of speeding and, with certain exceptions, differences between the two appeared to be constant. Third, a between-subject experimental manipulation involving the photographic animation measure of gap acceptance was used to demonstrate one application of these techniques.

Cervical cancer remains a devastating disease in Kenya accounting for more than 2000 deaths each year. Lack of information on cervical cancer prevention and management has been attributed to the apathy among women in seeking health interventions. Use of internet-based and mobile e-health tools could increase information access among cervical cancer patients. The objective of the study was; to establish the extent of use of mobile phones and internet by cervical cancer patients in accessing information related to cancer treatment and management.; find out the characteristics of patients associated with internet use and identify barriers faced by the patients in internet use. A cross sectional descriptive survey of 199 cervical patients visiting the two main referral hospitals in Kenya was done. A structured questionnaire was used to collect data. The average length of illness was 2.43 years (SD ± 3.0). Only 7.5 %( n=15) reported to having used the internet as a source of information. 92.5 %( n=184) did not use internet. With Multiple options, 70.9% did not know how to use a computer, 29.2% did not have access to a computer, 14.6% lacked the money to use computers at the local cyber cafe while other barriers identified accounted for 11.1%. Patients reported that the internet had an important role in the management of cancer of the cervix in health education (17.6%), online consultation (14.6%), booking of patients (13.6%), referrals (8.5%) and collecting data (7%).

Rationale and Objectives Inefficient transfer of personal health records among providers negatively impacts quality of health care and increases cost. This multicenter study evaluates the implementation of the first Internet-based image-sharing system that gives patients ownership and control of their imaging exams, including assessment of patient satisfaction. Materials and Methods Patients receiving any medical imaging exams in four academic centers were eligible to have images uploaded into an online, Internet-based personal health record. Satisfaction surveys were provided during recruitment with questions on ease of use, privacy and security, and timeliness of access to images. Responses were rated on a five-point scale and compared using logistic regression and McNemar's test. Results A total of 2562 patients enrolled from July 2012 to August 2013. The median number of imaging exams uploaded per patient was 5. Most commonly, exams were plain X-rays (34.7%), computed tomography (25.7%), and magnetic resonance imaging (16.1%). Of 502 (19.6%) patient surveys returned, 448 indicated the method of image sharing (Internet, compact discs [CDs], both, other). Nearly all patients (96.5%) responded favorably to having direct access to images, and 78% reported viewing their medical images independently. There was no difference between Internet and CD users in satisfaction with privacy and security and timeliness of access to medical images. A greater percentage of Internet users compared to CD users reported access without difficulty (88.3% vs. 77.5%, P < 0.0001). Conclusion A patient-directed, interoperable, Internet-based image-sharing system is feasible and surpasses the use of CDs with respect to accessibility of imaging exams while generating similar satisfaction with respect to privacy.

Regardless of whether a parent has Internet access at home, it is essential that parents learn with their children and be aware of where their travels on the Internet are taking them. Many libraries have Internet workshops for parents or children or both. In the excitement of looking at sites, children may not even realize they are reading. Many…

Internet has become a significant resource for dissemination of medical information. We sought to investigate prevalence and usage patterns of Internet access among consecutive patients with cardiovascular diseases. A cross-sectional study was performed using a questionnaire as study tool. Among patients with Internet access, the type of health information sought and the impact of these on daily life were assessed. Of 1063 patients invited to the study, 1000 patients [68% male gender, mean age 66 ± 11 years (range 27-83 years)] agreed to complete the questionnaire. 216/1000 (21.6%) used Internet to obtain information related to their disease. The patient education was graded as: low (15%), medium (66%) and high (19%). Reasons for Internet use were as follows: 24-h availability 142/216 (65.7%); free of charge 58/216 (26.9%); and anonymity 50/216 (23.2%). Younger (≤ 66 years) age (35.2% vs. 15.3%; p = 0.0001), male gender (24.6% vs. 15.4%; p = 0.001) and higher education level (49.4% vs. 16.1%; p = 0.001) were significantly associated with Internet use. 30.6% (66/216) of Internet users changed their individual health behaviour attributable to information found on the Internet. However, this was not related to age, gender or level of education (p = 0.5, p = 0.6 and p = 0.4, respectively). Patients without Internet use obtain health information mainly from the pharmacist (62%) or from their treating physician (58%). A relevant number of patients with cardiovascular disease access the Internet for health information. The impact of such information on health-related behaviour in daily life was low. © 2013 John Wiley & Sons Ltd.

Call for Papers: Optical Access Networks With the wide deployment of fiber-optic technology over the past two decades, we have witnessed a tremendous growth of bandwidth capacity in the backbone networks of today's telecommunications infrastructure. However, access networks, which cover the "last-mile" areas and serve numerous residential and small business users, have not been scaled up commensurately. The local subscriber lines for telephone and cable television are still using twisted pairs and coaxial cables. Most residential connections to the Internet are still through dial-up modems operating at a low speed on twisted pairs. As the demand for access bandwidth increases with emerging high-bandwidth applications, such as distance learning, high-definition television (HDTV), and video on demand (VoD), the last-mile access networks have become a bandwidth bottleneck in today's telecommunications infrastructure. To ease this bottleneck, it is imperative to provide sufficient bandwidth capacity in the access networks to open the bottleneck and thus present more opportunities for the provisioning of multiservices. Optical access solutions promise huge bandwidth to service providers and low-cost high-bandwidth services to end users and are therefore widely considered the technology of choice for next-generation access networks. To realize the vision of optical access networks, however, many key issues still need to be addressed, such as network architectures, signaling protocols, and implementation standards. The major challenges lie in the fact that an optical solution must be not only robust, scalable, and flexible, but also implemented at a low cost comparable to that of existing access solutions in order to increase the economic viability of many potential high-bandwidth applications. In recent years, optical access networks have been receiving tremendous attention from both academia and industry. A large number of research activities have been carried out or

Internet addiction is the coming problem around the world. The diagnostic criteria for Internet addiction among adolescents (DC-IA-A) has become a widely used measure for assessing the presence of Internet addiction in Taiwan. This study examined the diagnosis criteria for Internet addiction in adolescents by expert evaluation. Twenty psychiatrists rated the adequacy of each criterion in DC-IA-A. The content validity and homogeneity reliability proposed by Aiken were calculated. The coefficients content validity and homogeneity reliability showed twenty psychiatrists agreed on each of DC-IA-A as relevant to the diagnosis of Internet addiction, though several criteria need improvements. Two criteria "excessive time spent on Internet activities and leaving the Internet" and "excessive effort spent on activities necessary to obtain access to the Internet" should be omitted, and the criteria of "tolerance" should be modified. The diagnostic criteria for Internet addiction among adolescents should be revised to meet the real condition of this population. Copyright © 2014. Published by Elsevier B.V.
