The challenges of providing quality respiratory care to persons living in rural or remote communities can be daunting. These populations are often vulnerable in terms of both health status and access to care, highlighting the need for innovation in service delivery. The rapidly expanding options available using telehealthcare technologies have the capacity to allow patients in rural and remote communities to connect with providers at distant sites and to facilitate the provision of diagnostic, monitoring, and therapeutic services. Successful implementation of telehealthcare programs in rural and remote settings is, however, contingent upon accounting for key technical, organizational, social, and legal considerations at the individual, community, and system levels. This review article discusses five types of telehealthcare delivery that can facilitate respiratory care for residents of rural or remote communities: remote monitoring (including wearable and ambient systems; remote consultations (between providers and between patients and providers), remote pulmonary rehabilitation, telepharmacy, and remote sleep monitoring. Current and future challenges related to telehealthcare are discussed. PMID:26902542

Advances in information technology have increased remote access to the electronic health record (EHR). Concurrently, standards defining appropriate resident supervision have evolved. How often and under what circumstances inpatient attending physicians remotely access the EHR for resident supervision is unknown. We described a model of attending remote EHR use for resident supervision, and quantified the frequency and magnitude of use. Using a mixed methods approach, general medicine inpatient attendings were surveyed and interviewed about their remote EHR use. Frequency of use and supervisory actions were quantitatively examined via survey. Transcripts from semistructured interviews were analyzed using grounded theory to identify codes and themes. A total of 83% (59 of 71) of attendings participated. Fifty-seven (97%) reported using the EHR remotely, with 54 (92%) reporting they discovered new clinical information not relayed by residents via remote EHR use. A majority (93%, 55 of 59) reported that this resulted in management changes, and 54% (32 of 59) reported making immediate changes by contacting cross-covering teams. Six major factors around remote EHR use emerged: resident, clinical, educational, personal, technical, and administrative. Attendings described resident and clinical factors as facilitating "backstage" supervision via remote EHR use. In our study to assess attending remote EHR use for resident supervision, attendings reported frequent remote use with resulting supervisory actions, describing a previously uncharacterized form of "backstage" oversight supervision. Future work should explore best practices in remote EHR use to provide effective supervision and ultimately improve patient safety.

A Lightweight Remote Parallel Visualization Platform for Interactive Massive Time-varying Climate Data Analysis

Li, J.; Zhang, T.; Huang, Q.; Liu, Q.

2014-12-01

Today's climate datasets are featured with large volume, high degree of spatiotemporal complexity and evolving fast overtime. As visualizing large volume distributed climate datasets is computationally intensive, traditional desktop based visualization applications fail to handle the computational intensity. Recently, scientists have developed remote visualization techniques to address the computational issue. Remote visualization techniques usually leverage server-side parallel computing capabilities to perform visualization tasks and deliver visualization results to clients through network. In this research, we aim to build a remote parallel visualization platform for visualizing and analyzing massive climate data. Our visualization platform was built based on Paraview, which is one of the most popular open source remote visualization and analysis applications. To further enhance the scalability and stability of the platform, we have employed cloud computing techniques to support the deployment of the platform. In this platform, all climate datasets are regular grid data which are stored in NetCDF format. Three types of data access methods are supported in the platform: accessing remote datasets provided by OpenDAP servers, accessing datasets hosted on the web visualization server and accessing local datasets. Despite different data access methods, all visualization tasks are completed at the server side to reduce the workload of clients. As a proof of concept, we have implemented a set of scientific visualization methods to show the feasibility of the platform. Preliminary results indicate that the framework can address the computation limitation of desktop based visualization applications.

USGS Provision of Near Real Time Remotely Sensed Imagery for Emergency Response

NASA Astrophysics Data System (ADS)

Jones, B. K.

2014-12-01

The use of remotely sensed imagery in the aftermath of a disaster can have an important impact on the effectiveness of the response for many types of disasters such as floods, earthquakes, volcanic eruptions, landslides, and other natural or human-induced disasters. Ideally, responders in areas that are commonly affected by disasters would have access to archived remote sensing imagery plus the ability to easily obtain the new post event data products. The cost of obtaining and storing the data and the lack of trained professionals who can process the data into a mapping product oftentimes prevent this from happening. USGS Emergency Operations provides remote sensing and geospatial support to emergency managers by providing access to satellite images from numerous domestic and international space agencies including those affiliated with the International Charter Space and Major Disasters and their space-based assets and by hosting and distributing thousands of near real time event related images and map products through the Hazards Data Distribution System (HDDS). These data may include digital elevation models, hydrographic models, base satellite images, vector data layers such as roads, aerial photographs, and other pre and post disaster data. These layers are incorporated into a Web-based browser and data delivery service, the Hazards Data Distribution System (HDDS). The HDDS can be made accessible either to the general public or to specific response agencies. The HDDS concept anticipates customer requirements and provides rapid delivery of data and services. This presentation will provide an overview of remotely sensed imagery that is currently available to support emergency response operations and examples of products that have been created for past events that have provided near real time situational awareness for responding agencies.

The U.S. Geological Survey has been a provider of remotely sensed information for decades. As the availability and use of satellite data has grown, USGS has placed increasing emphasis on expanding the knowledge about the science of remote sensing and on making remotely sensed data more accessible. USGS encourages widespread availability and distribution of these data and through its programs, encourages and enables a variety of research activities and the development of useful applications of the data. The science of remote sensing has great potential for assisting in the monitoring and assessment of the impacts of natural disasters, management and analysis of environmental, biological, energy, and mineral investigations, and supporting informed public policy decisions. By establishing the Land Remote Sensing Program (LRS) as a major unit of the USGS Geography Program, USGS has taken the next step to further increase support for the accessibility, understanding, and use of remotely sensed data. This article describes the LRS Program, its mission and objectives, and how the program has been structured to accomplish its goals.

2011-12-01

In the past, access to remote storage was considered to be at least one order of magnitude slower than local disk access. Improvement on network technologies provide the alternative of using remote disk. For those accesses one can today reach levels of throughput similar or exceeding those of local disks. Common choices as access protocols in the WLCG collaboration are RFIO, [GSI]DCAP, GRIDFTP, XROOTD and NFS. HTTP protocol shows a promising alternative as it is a simple, lightweight protocol. It also enables the use of standard technologies such as http caching or load balancing which can be used to improve service resilience and scalability or to boost performance for some use cases seen in HEP such as the "hot files". WebDAV extensions allow writing data, giving it enough functionality to work as a remote access protocol. This paper will show our experiences with the WebDAV door for dCache, in terms of functionality and performance, applied to some of the HEP work flows in the LHC Tier1 at PIC.

Our study reviewed policies in 8 high-income countries (Australia, Canada, United States, Italy, Spain, United Kingdom, Croatia and Estonia) in Europe, Australasia and North America with regard to hospitals in rural or remote areas. We explored whether any specific policies on hospitals in rural or remote areas are in place, and, if not, how countries made sure that the population in remote or rural areas has access to acute inpatient services. We found that only one of the eight countries (Italy) had drawn up a national policy on hospitals in rural or remote areas. In the United States, although there is no singular comprehensive national plan or vision, federal levers have been used to promote access in rural or remote areas and provide context for state and local policy decisions. In Australia and Canada, intermittent policies have been developed at the sub-national level of states and provinces respectively. In those countries where access to hospital services in rural or remote areas is a concern, common challenges can be identified, including the financial sustainability of services, the importance of medical education and telemedicine and the provision of quick transport to more specialized services.

2005-01-01

The U. S. Geological Survey's (USGS) Commercial Remote Sensing Data Contracts (CRSDCs) provide government agencies with access to a broad range of commercially available remotely sensed airborne and satellite data. These contracts were established to support The National Map partners, other Federal Civilian agency programs, and Department of Defense programs that require data for the United States and its territories. Experience shows that centralized procurement of remotely sensed data leads to considerable cost savings to the Federal government through volume discounts, reduction of redundant contract administrative costs, and avoidance of duplicate purchases. These contracts directly support the President's Commercial Remote Sensing Space Policy, signed in 2003, by providing a centralized mechanism for civil agencies to acquire commercial remote sensing products to support their mission needs in an efficient and coordinated way. CRSDC administration is provided by the USGS Mid-Continent Mapping Center in Rolla, Missouri.

Kassell, N F; Downs, J H; Graves, B S

1997-01-01

This paper describes the Integrated Remote Neurosurgical System (IRNS), a remotely-operated neurosurgical microscope with high-speed communications and a surgeon-accessible user interface. The IRNS will allow high quality bidirectional mentoring in the neurosurgical suite. The research goals of this effort are twofold: to develop a clinical system allowing a remote neurosurgeon to lend expertise to the OR-based neurosurgical team and to provide an integrated training environment. The IRNS incorporates a generic microscope/transport model, Called SuMIT (Surgical Manipulator Interface Translator). Our system is currently under test using the Zeiss MKM surgical transport. A SuMIT interface is also being constructed for the Robotics Research 1607. The IRNS Remote Planning and Navigation Workstation incorporates surgical planning capabilities, real-time, 30 fps video from the microscope and overhead video camera. The remote workstation includes a force reflecting handcontroller which gives the remote surgeon an intuitive way to position the microscope head. Bidirectional audio, video whiteboarding, and image archiving are also supported by the remote workstation. A simulation mode permits pre-surgical simulation, post-surgical critique, and training for surgeons without access to an actual microscope transport system. The components of the IRNS are integrated using ATM switching to provide low latency data transfer. The research, along with the more sophisticated systems that will follow, will serve as a foundation and test-bed for extending the surgeon's skills without regard to time zone or geographic boundaries.

Access to existing travel data is critical for many analysis efforts that lack the time or resources to support detailed data collection. High-resolution data sets provide particular value, but also present a challenge for preserving the anonymity of the original survey participants. To address this dilemma of providing data access while preserving privacy, the National Renewable Energy Laboratory and the U.S. Department of Transportation have launched the Transportation Secure Data Center (TSDC). TSDC data sets include those from regional travel surveys and studies that increasingly use global positioning system devices. Data provided by different collecting agencies varies with respect tomore » formatting, elements included and level of processing conducted in support of the original purpose. The TSDC relies on a number of geospatial and other analysis tools to ensure data quality and to generate useful information outputs. TSDC users can access the processed data in two different ways. The first is by downloading summary results and second-by-second vehicle speed profiles (with latitude/longitude information removed) from a publicly-accessible website. The second method involves applying for a remote connection account to a controlled-access environment where spatial analysis can be conducted, but raw data cannot be removed.« less

Real-time access to solar-terrestrial data is becoming increasingly important, not only because it is now possible to acquire and access data rapidly via the internet, but also because of the need for timely publication of real-time data for analysis and modeling efforts. Currently, engineering-scaled summary data are available routinely on a daily basis from many observatories, but only when the observatories have continuous, or at least daily network access. Increasingly, the upgrading of remote data acquisition hardware makes it possible to provide data in real-time, and it is becoming normal to expect timely access to data products. The NSF- supported PENGUIn/AGO constellation of autonomous Antarctic research observatories has provided real-time data since December, 2002, when Iridium satellite modems were installed at three sites. The Iridium telecommunications links are maintained continuously, transferring data between the remote observatories and a U.S.-based data acquisition site. The time-limiting factor with this scenario is now the delay in completing a data record before transmission, which can be as short as minutes depending on the sampling rate. The single-channel data throughput of the current systems is 20-MB/day (megabytes per day), but planned installations will be capable of operating with multiple modem channels. The data records are currently posted immediately to a web site accessible by anonymous FTP client software, for use by the instruments' principal investigators, and survey plots of selected signals are published daily. The web publication facilities are being upgraded, in order to allow other interested researchers rapid access to engineering-scaled data products, in several common formats, as well as providing interactive plotting capabilities. The web site will provide access to data from other collaborating observatories (including South Pole and McMurdo Stations), as well as ancillary data accessible from public sites (e.g., Kp, AE, Dst). The site will be accessible via common HTML interface protocols, enabling access to the data products by browsers or other compatible application software. We describe details of the hardware and software components of the Iridium telecommunications linkage, as well as details of the current and planned web publication capabilities.

Residents of remote communities face inequities in access to specialists, excessive wait times, and poorly coordinated care. The Champlain BASE TM (Building Access to Specialists through eConsultation) service facilitates asynchronous communication between primary care providers (PCP) and specialists. The service was extended to several PCPs in Nunavut in 2014. To (1) describe the use of eConsult services in Nunavut, and (2) conduct a costing evaluation. A cross-sectional study and cost analysis of all eConsult cases submitted between August 2014 and April 2016. PCPs from Nunavut submitted 165 eConsult cases. The most popular specialties were dermatology (16%), cardiology (8%), endocrinology (7%), otolaryngology (7%), and obstetrics/gynaecology (7%). Specialists provided a response in a median of 0.9 days (IQR=0.3-3.0, range=0.01-15.02). In 35% of cases, PCPs were able to avoid the face-to-face specialist visits they had originally planned for their patients. Total savings associated with eConsult in Nunavut are estimated at $180,552.73 or $1,100.93 per eConsult. The eConsult service provided patients in Nunavut's remote communities with prompt access to specialist advice. The service's chief advantage in Canada's northern communities is its ability to offer electronic access to a breadth of specialties far greater than could be supported locally. Our findings suggest that a territory-wide adoption of eConsult would generate enormous savings.

Grady, Brian J

2002-01-01

The National Naval Medical Center, Bethesda, Maryland, integrated telemental health care into its primary behavioral health-care outreach service in 1998. To date, there have been over 1,800 telemental health visits, and the service encounters approximately 100 visits per month at this time. The objective of this study was to compare and contrast the costs to the beneficiary, the medical system, and the military organization as a whole via one of the four methods currently employed to access mental health care from remotely located military medical clinics. The four methods include local access via the military's civilian health maintenance organization (HMO) network, patient travel to the military treatment facility, military mental health specialists' travel to the remote clinic (circuit riding) and TeleMental Healthcare (TMH). Interactive video conferencing, phone, electronic mail, and facsimile were used to provide telemental health care from a military treatment facility to a remote military medical clinic. The costs of health-care services, equipment, patient travel, lost work time, and communications were tabulated and evaluated. While the purpose of providing telemental healthcare services was to improve access to mental health care for our beneficiaries at remote military medical clinics, it became apparent that this could be done at comparable or reduced costs.

CDC WONDER: a cooperative processing architecture for public health.

PubMed Central

Friede, A; Rosen, D H; Reid, J A

1994-01-01

CDC WONDER is an information management architecture designed for public health. It provides access to information and communications without the user's needing to know the location of data or communication pathways and mechanisms. CDC WONDER users have access to extractions from some 40 databases; electronic mail (e-mail); and surveillance data processing. System components include the Remote Client, the Communications Server, the Queue Managers, and Data Servers and Process Servers. The Remote Client software resides in the user's machine; other components are at the Centers for Disease Control and Prevention (CDC). The Remote Client, the Communications Server, and the Applications Server provide access to the information and functions in the Data Servers and Process Servers. The system architecture is based on cooperative processing, and components are coupled via pure message passing, using several protocols. This architecture allows flexibility in the choice of hardware and software. One system limitation is that final results from some subsystems are obtained slowly. Although designed for public health, CDC WONDER could be useful for other disciplines that need flexible, integrated information exchange. PMID:7719813

Implementing an anti-smoking program in rural-remote communities: challenges and strategies.

PubMed

Tall, Julie A; Brew, Bronwyn K; Saurman, Emily; Jones, Therese C

2015-01-01

Rural-remote communities report higher smoking rates and poorer health outcomes than that of metropolitan areas. While anti-smoking programs are an important measure for addressing smoking and improving health, little is known of the challenges faced by primary healthcare staff implementing those programs in the rural-remote setting. The aim of this study was to explore the challenges and strategies of implementing an anti-smoking program by primary healthcare staff in rural-remote Australia. Guided by a phenomenological approach, semi-structured interviews and focus groups were conducted with health service managers, case managers and general practitioners involved in program implementation in Australian rural-remote communities between 2008 and 2010. Program implementation was reported to be challenged by limited primary and mental healthcare resources and client access to services; limited collaboration between health services; the difficulty of accessing staff training; high levels of community distress and disadvantage; the normalisation of smoking and its deleterious impact on smoking abstinence among program clients; and low morale among health staff. Strategies identified to overcome challenges included appointing tobacco-dedicated staff; improving health service collaboration, access and flexibility; providing subsidised pharmacotherapies and boosting staff morale. Findings may assist health services to better tailor anti-smoking programs for the rural-remote setting, where smoking rates are particularly high. Catering for the unique challenges of the rural-remote setting is necessary if anti-smoking programs are to be efficacious, cost-effective and capable of improving rural-remote health outcomes.

Humer, Michael F; Campling, Barbara G

2017-08-01

The purpose of this study is to review the role of telemedicine in providing oncology care; we describe our long-standing, high-volume telemedicine experience. The Interior Health Thoracic Surgical Group (IHTSG) uses telemedicine, through Virtual Thoracic Surgical Clinics (VTSC), to provide service to remote patients. The IHTSG serves a population of 1.01 million people over an area of 807,538 km 2 (1.3 persons/km 2 ) in the Interior and North of British Columbia, Canada. Between 2003 and 2015, the IHTSG conducted 15,073 telemedicine patient encounters at 63 geographic sites. Telemedicine saved these patients a total travel distance of 11.5 million km-an average of 766 km per patient. VTSC supports and strengthens the Hub and Spoke model of healthcare delivery-patients residing remotely can easily access centrally delivered service. Telemedicine makes specialized care available to all patients by overcoming a major impediment to access, namely distance.

Increasing Access and Usability of Remote Sensing Data: The NASA Protected Area Archive

NASA Technical Reports Server (NTRS)

Geller, Gary N.

2004-01-01

Although remote sensing data are now widely available, much of it at low or no-cost, many managers of protected conservation areas do not have the expertise or tools to view or analyze it. Thus access to it by the protected area management community is effectively blocked. The Protected Area Archive will increase access to remote sensing data by creating collections of satellite images of protected areas and packaging them with simple-to-use visualization and analytical tools. The user can easily locate the area and image of interest on a map, then display, roam, and zoom the image. A set of simple tools will be provided so the user can explore the data and employ it to assist in management and monitoring of their area. The 'Phase 1 ' version requires only a Windows-based computer and basic computer skills, and may be of particular help to protected area managers in developing countries.

Remote laboratories for optical metrology: from the lab to the cloud

Osten, W.; Wilke, M.; Pedrini, G.

2012-10-01

The idea of remote and virtual metrology has been reported already in 2000 with a conceptual illustration by use of comparative digital holography, aimed at the comparison of two nominally identical but physically different objects, e.g., master and sample, in industrial inspection processes. However, the concept of remote and virtual metrology can be extended far beyond this. For example, it does not only allow for the transmission of static holograms over the Internet, but also provides an opportunity to communicate with and eventually control the physical set-up of a remote metrology system. Furthermore, the metrology system can be modeled in the environment of a 3D virtual reality using CAD or similar technology, providing a more intuitive interface to the physical setup within the virtual world. An engineer or scientist who would like to access the remote real world system can log on to the virtual system, moving and manipulating the setup through an avatar and take the desired measurements. The real metrology system responds to the interaction between the avatar and the 3D virtual representation, providing a more intuitive interface to the physical setup within the virtual world. The measurement data are stored and interpreted automatically for appropriate display within the virtual world, providing the necessary feedback to the experimenter. Such a system opens up many novel opportunities in industrial inspection such as the remote master-sample-comparison and the virtual assembling of parts that are fabricated at different places. Moreover, a multitude of new techniques can be envisaged. To them belong modern ways for documenting, efficient methods for metadata storage, the possibility for remote reviewing of experimental results, the adding of real experiments to publications by providing remote access to the metadata and to the experimental setup via Internet, the presentation of complex experiments in classrooms and lecture halls, the sharing of expensive and complex infrastructure within international collaborations, the implementation of new ways for the remote test of new devices, for their maintenance and service, and many more. The paper describes the idea of remote laboratories and illustrates the potential of the approach on selected examples with special attention to optical metrology.

There is a lack of access to simulation-based education (SBE) for professional entry students (PES) and health professionals at rural and remote locations. A descriptive study. Health and education facilities in regional South Australia and south-west Victoria. Number of training recipients who participated in SBE; geographical distribution and locations where SBE was delivered; number of rural clinical educators providing SBE. A distributed model to deliver SBE in rural and remote locations in collaboration with local health and community services, education providers and the general public. Face-to-face meetings with health services and education providers identified gaps in locally delivered clinical skills training and availability of simulation resources. Clinical leadership, professional development and community of practice strategies were implemented to enhance capacity of rural clinical educators to deliver SBE. The number of SBE participants and training hours delivered exceeded targets. The distributed model enabled access to regular, localised training for PES and health professionals, minimising travel and staff backfill costs incurred when attending regional centres. The skills acquired by local educators remain in rural areas to support future training. The distributed collaborative model substantially increased access to clinical skills training for PES and health professionals in rural and remote locations. Developing the teaching skills of rural clinicians optimised the use of simulation resources. Consequently, health services were able to provide students with flexible and realistic learning opportunities in clinical procedures, communication techniques and teamwork skills. © 2017 National Rural Health Alliance Inc.

To explore the experiences of women from a remote and rural setting who had a termination of pregnancy (TOP), in relation to any barriers they may have experienced trying to access TOP. Qualitative interview study. Scottish Highlands and Western Isles. Women who had undergone TOP in the Scottish Highlands National Health Service between October 2014 and May 2015. Sixteen semi-structured, audio-recorded telephone interviews were conducted by a researcher with women who had consented to be interviewed at their initial assessment. Six stages of thematic analysis were followed to explore themes in and across participant accounts. Themes derived from interview transcripts. Four themes emerged relating to barriers to access and experience: (1) the impact of travel for TOP, (2) temporal factors unique to this population and how they affected women, (3) the attitude of health professionals, notably general practitioners, as a result of local culture, and (4) stigma surrounding TOP and the expectation that abortion will be traumatising. Women in remote and rural areas experience barriers to accessing TOP. Prompt referrals, more providers of TOP and tackling stigma associated with TOP could make delivery of this service more equitable and improve women's journey through TOP. Women in remote and rural areas of Scotland face multiple barriers to accessing termination of pregnancy. © 2016 Royal College of Obstetricians and Gynaecologists.

2009-05-01

This paper reports on test-bed for the long-term health monitoring system for bridge structures employing fiber Bragg grating (FBG) sensors, which is remotely accessible via the web, to provide real-time quantitative information on a bridge's response to live loading and environmental changes, and fast prediction of the structure's integrity. The sensors are attached on several locations of the structure and connected to a data acquisition system permanently installed onsite. The system can be accessed through remote communication using an optical cable network, through which the evaluation of the bridge behavior under live loading can be allowed at place far away from the field. Live structural data are transmitted continuously to the server computer at the central office. The server computer is connected securely to the internet, where data can be retrieved, processed and stored for the remote web-based health monitoring. Test-bed revealed that the remote health monitoring technology will enable practical, cost-effective, and reliable condition assessment and maintenance of bridge structures.

OASIS: A Data Fusion System Optimized for Access to Distributed Archives

NASA Astrophysics Data System (ADS)

Berriman, G. B.; Kong, M.; Good, J. C.

2002-05-01

The On-Line Archive Science Information Services (OASIS) is accessible as a java applet through the NASA/IPAC Infrared Science Archive home page. It uses Geographical Information System (GIS) technology to provide data fusion and interaction services for astronomers. These services include the ability to process and display arbitrarily large image files, and user-controlled contouring, overlay regeneration and multi-table/image interactions. OASIS has been optimized for access to distributed archives and data sets. Its second release (June 2002) provides a mechanism that enables access to OASIS from "third-party" services and data providers. That is, any data provider who creates a query form to an archive containing a collection of data (images, catalogs, spectra) can direct the result files from the query into OASIS. Similarly, data providers who serve links to datasets or remote services on a web page can access all of these data with one instance of OASIS. In this was any data or service provider is given access to the full suite of capabilites of OASIS. We illustrate the "third-party" access feature with two examples: queries to the high-energy image datasets accessible from GSFC SkyView, and links to data that are returned from a target-based query to the NASA Extragalactic Database (NED). The second release of OASIS also includes a file-transfer manager that reports the status of multiple data downloads from remote sources to the client machine. It is a prototype for a request management system that will ultimately control and manage compute-intensive jobs submitted through OASIS to computing grids, such as request for large scale image mosaics and bulk statistical analysis.

Effect of security threats on primary care access in Logar province, Afghanistan.

PubMed

Morikawa, Masahiro J

2008-01-01

Security threats are a major concern for access to health care in many war-torn communities; however, there is little quantified data on actual access to care in rural communities during war. Kinderberg International e.V. provided primary care in rural Logar province, Afghanistan, for these three years in eight districts until they were integrated into the new health care structure led by the Ministry of Health in early 2005. We examined the number of patients visiting our clinic before and during the security threats related to the parliamentary election and subsequent national assembly in 2004. The number of patients declined in remote clinics while the number increased in central locations. This finding has an important practical implication: the monitoring of access to care should include remote clinics, otherwise it may potentially underestimate compromised access to health care due to security threats.

Road access can influence protective and risk factors associated with nutrition by affecting various social and biological processes. In northern coastal Ecuador, the construction of new roads created a remoteness gradient among villages, providing a unique opportunity to examine the impact of roads on child nutritional outcomes 10 years after the road was built. Anthropometric and haemoglobin measurements were collected from 2,350 children <5 years in Esmeraldas, Ecuador, from 2004 to 2013 across 28 villages with differing road access. Logistic generalized estimating equation models assessed the longitudinal association between village remoteness and prevalence of stunting, wasting, underweight, overweight, obesity, and anaemia. We examined the influence of socio-economic characteristics on the pathway between remoteness and nutrition by comparing model results with and without household-level socio-economic covariates. Remoteness was associated with stunting (OR = 0.43, 95% CI [0.30, 0.63]) and anaemia (OR = 0.56, 95% CI [0.44, 0.70]). Over time, the prevalence of stunting was generally decreasing but remained higher in villages closer to the road compared to those farther away. Obesity increased (0.5% to 3%) over time; wasting was high (6%) but stable during the study period. Wealth and education partially explained the better nutritional outcomes in remote vs. road villages more than a decade after some communities gained road access. Establishing the extent to which these patterns persist requires additional years of observation. © 2018 John Wiley & Sons Ltd.

Specialist clinics in remote Australian Aboriginal communities: where rock art meets rocket science.

PubMed

Gruen, Russell; Bailie, Ross

2004-10-01

People in remote Aboriginal communities in the Northern Territory have greater morbidity and mortality than other Australians, but face considerable barriers when accessing hospital-based specialist services. The Specialist Outreach Service, which began in 1997, was a novel policy initiative to improve access by providing a regular multidisciplinary visiting specialist services to remote communities. It led to two interesting juxtapositions: that of 'state of the art' specialist services alongside under-resourced primary care in remote and relatively traditional Aboriginal communities; and that of attempts to develop an evidence base for the effectiveness of outreach, while meeting the short-term evaluative requirements of policy-makers. In this essay, first we describe the development of the service in the Northern Territory and its initial process evaluation. Through a Cochrane systematic review we then summarise the published research on the effectiveness of specialist outreach in improving access to tertiary and hospital-based care. Finally we describe the findings of an observational population-based study of the use of specialist services and the impact of outreach to three remote communities over 11 years. Specialist outreach improves access to specialist care and may lessen the demand for both outpatient and inpatient hospital care. Specialist outreach is, however, dependent on well-functioning primary care. According to the way in which outreach is conducted and the service is organised, it can either support primary care or it can hinder primary care and, as a result, reduce its own effectiveness.

Collaborative learning using Internet2 and remote collections of stereo dissection images.

PubMed

Dev, Parvati; Srivastava, Sakti; Senger, Steven

2006-04-01

We have investigated collaborative learning of anatomy over Internet2, using an application called remote stereo viewer (RSV). This application offers a unique method of teaching anatomy, using high-resolution stereoscopic images, in a client-server architecture. Rotated sequences of stereo image pairs were produced by volumetric rendering of the Visible female and by dissecting and photographing a cadaveric hand. A client-server application (RSV) was created to provide access to these image sets, using a highly interactive interface. The RSV system was used to provide a "virtual anatomy" session for students in the Stanford Medical School Gross Anatomy course. The RSV application allows both independent and collaborative modes of viewing. The most appealing aspects of the RSV application were the capacity for stereoscopic viewing and the potential to access the content remotely within a flexible temporal framework. The RSV technology, used over Internet2, thus serves as an effective complement to traditional methods of teaching gross anatomy. (c) 2006 Wiley-Liss, Inc.

Creating high-performance means to manage massive hyperspectral data (HSD) arrays is an actual challenge when it is implemented to deal with disparate information resources. Aiming to solve this problem the present work develops tools to work with HSD in a distributed information infrastructure, i.e. primarily to use those tools in remote access mode. The main feature of presented approach is in the development of remotely accessed services, which allow users both to conduct search and retrieval procedures on HSD sets and to provide target users with tools to analyze and to process HSD in remote mode. These services were implemented within VEGA-Constellation family information systems that were extended by adding tools oriented to support the studies of certain classes of natural objects by exploring their HSD. Particular developed tools provide capabilities to conduct analysis of such objects as vegetation canopies (forest and agriculture), open soils, forest fires, and areas of thermal anomalies. Developed software tools were successfully tested on Hyperion data sets.

Systems and methods for dismantling a nuclear reactor are described. In one aspect the system includes a remotely controlled heavy manipulator ("manipulator") operatively coupled to a support structure, and a control station in a non-contaminated portion of a workspace. The support structure provides the manipulator with top down access into a bioshield of a nuclear reactor. At least one computing device in the control station provides remote control to perform operations including: (a) dismantling, using the manipulator, a graphite moderator, concrete walls, and a ceiling of the bioshield, the manipulator being provided with automated access to all internal portions of the bioshield; (b) loading, using the manipulator, contaminated graphite blocks from the graphite core and other components from the bioshield into one or more waste containers; and (c) dispersing, using the manipulator, dust suppression and contamination fixing spray to contaminated matter.

Rural and remote dental services shortages: filling the gaps through geo-spatial analysis evidence-based targeting.

PubMed

Shiika, Yulia; Kruger, Estie; Tennant, Marc

Australia has a significant mal-distribution of its limited dental workforce. Outside the major capital cities, the distribution of accessible dental care is at best patchy. This study applied geo-spatial analysis technology to locate gaps in dental service accessibility for rural and remote dwelling Australians, in order to test the hypothesis that there are a few key location points in Australia where further dental services could make a significant contribution to ameliorating the immediate shortage crisis. A total of 2,086 dental practices were located in country areas, covering a combined catchment area of 1.84 million square kilometers, based on 50 km catchment zones around each clinic. Geo-spatial analysis technology was used to identify gaps in the accessibility of dental services for rural and remote dwelling Australians. An extraction of data was obtained to analyse the integrated geographically-aligned database. Results: Resolution of the lack of dental practices for 74 townships (of greater than 500 residents) across Australia could potentially address access for 104,000 people. An examination of the socio-economic mix found that the majority of the dental practices (84%) are located in areas classified as less disadvantaged. Output from the study provided a cohesive national map that has identified locations that could have health improvement via the targeting of dental services to that location. The study identified potential location sites for dental clinics, to address the current inequity in accessing dental services in rural and remote Australia.

Teledermatology provides a partial solution to the problem of accessibility to dermatology services in underserved areas, yet methodologies to determine the locations and geographic dimensions of these areas and the locational efficiency of remote teledermatology sites have been found wanting. This article illustrates an innovative Geographic Information Systems approach using dermatologists' addresses, U.S. Census population data, and the Topologically Integrated Geographic Encoding and Referencing System. Travel-time-based service areas were calculated and mapped for each dermatologist in the state of Kentucky and for possible locations of several remote teledermatology sites. Populations within the current and possible remote service areas were determined. These populations and associated maps permit assessment of the locational efficiency of the current distribution of dermatologists, location of underserved areas, and the potential contribution of proposed hypothetical teledermatology sites. This approach is a valuable and practical tool for evaluating access to current distributions of dermatologists as well as planning for and implementing teledermatology.

The expansion of neuromodulation and its indications has resulted in hundreds of thousands of patients with implanted devices worldwide. Because all patients require programming, this growth has created a heavy burden on neuromodulation centers and patients. Remote point-of-care programming may provide patients with real-time access to neuromodulation expertise in their communities. To test the feasibility of remotely programming a neuromodulation device using a remote-presence robot and to determine the ability of an expert programmer to telementor a nonexpert in programming the device. A remote-presence robot (RP-7) was used for remote programming. Twenty patients were randomly assigned to either conventional programming or a robotic session. The expert remotely mentored 10 nurses with no previous experience to program the devices of patients assigned to the remote-presence sessions. Accuracy of programming, adverse events, and satisfaction scores for all participants were assessed. There was no difference in the accuracy or clinical outcomes of programming between the standard and remote-presence sessions. No adverse events occurred in any session. The patients, nurses, and the expert programmer expressed high satisfaction scores with the remote-presence sessions. This study establishes the proof-of-principle that remote programming of neuromodulation devices using telepresence and expert telementoring of an individual with no previous experience to accurately program a device is feasible. We envision a time in the future when patients with implanted devices will have real-time access to neuromodulation expertise from the comfort of their own home.

Development of a fusion approach selection tool

Pohl, C.; Zeng, Y.

2015-06-01

During the last decades number and quality of available remote sensing satellite sensors for Earth observation has grown significantly. The amount of available multi-sensor images along with their increased spatial and spectral resolution provides new challenges to Earth scientists. With a Fusion Approach Selection Tool (FAST) the remote sensing community would obtain access to an optimized and improved image processing technology. Remote sensing image fusion is a mean to produce images containing information that is not inherent in the single image alone. In the meantime the user has access to sophisticated commercialized image fusion techniques plus the option to tune the parameters of each individual technique to match the anticipated application. This leaves the operator with an uncountable number of options to combine remote sensing images, not talking about the selection of the appropriate images, resolution and bands. Image fusion can be a machine and time-consuming endeavour. In addition it requires knowledge about remote sensing, image fusion, digital image processing and the application. FAST shall provide the user with a quick overview of processing flows to choose from to reach the target. FAST will ask for available images, application parameters and desired information to process this input to come out with a workflow to quickly obtain the best results. It will optimize data and image fusion techniques. It provides an overview on the possible results from which the user can choose the best. FAST will enable even inexperienced users to use advanced processing methods to maximize the benefit of multi-sensor image exploitation.

A complete image management and communications system has been installed at Georgetown University Hospital (GUH). The network is based on the A T & T CommView System. In the Neuroradiology Division, this comprehensive network supports a multiscreen workstation with access to multiple imaging modalities such as CT and MRI from both the hospital and a remote imaging center. In addition, the radiologist can access these images from various workstations located throughout the hospital as well as from remote sites such as the home. Among the radiology services supported by the network, neuroradiology has the greatest need for such a system with extensive daily requirements involving the remote imaging center and on-line consultation around the clock. By providing neuroradiology with all available communication links, the radiologist can monitor, diagnose, and consult. The remote site has a subsystem capable of acquiring images and transmitting them over a high speed T1 data circuit. The GUH neuroradiologist can view these images on the neuro workstation or any of the workstations available in the Hospital. Fast and easy access to the images allows a radiologist to monitor multiple examinations as well as to utilize the workstation for diagnosis. To provide the neuroradiologist quick access to images at all times, a PC-based Results Viewing Station (RVS) has been placed in a doctor's home. Images may be sent to the RVS, or the user may request images from the central database at the hospital. Images can be viewed at home either as they are transmitted, or following transfer of a whole study. The efficiency and effectiveness of the system's capabilities with special regard to remote and teleradiology (RVS) operations have been studied for the neuroradiology service. This paper will discuss the current clinical acceptance and use, problems in implementation, and ways these difficulties are being surmounted.

The AmericaView Project - Putting the Earth into Your Hands

The U.S. Geological Survey (USGS) is a leader in collecting, archiving, and distributing geospatial data and information about the Earth. Providing quick, reliable access to remotely sensed images and geospatial data is the driving principle behind the AmericaView Project. A national not-for-profit organization, AmericaView, Inc. was established and is supported by the USGS to coordinate the activities of a national network of university-led consortia with the primary objective of the advancement of the science of remote sensing. Individual consortia members include academic institutions, as well as state, local, and tribal government agencies. AmericaView's focus is to expand the understanding and use of remote sensing through education and outreach efforts and to provide affordable, integrated remote sensing information access and delivery to the American public. USGS's Landsat and NASA's Earth Observing System (EOS) satellite data are downlinked from satellites or transferred from other facilities to the USGS Center for Earth Resources Observation and Science (EROS) ground receiving station in Sioux Falls, South Dakota. The data can then be transferred over high-speed networks to consortium members, where it is archived and made available for public use.

Infrastructure for Reaching Disadvantaged Consumers

Both consumers and health service providers need access to up-to-date information, including patient and practice guidelines, that allows them to make decisions in partnership about individual and public health in line with the primary health care model of health service delivery. Only then is it possible for patient preferences to be considered while the health of the general population is improved. The Commonwealth Government of Australia has allocated $250 million over five years, starting July 1, 1997, to support activities and projects designed to meet a range of telecommunication needs in regional, rural, and remote Australia. This paper defines rural and remote communities, then reviews rural and remote health services, information, and telecommunication technology infrastructures and their use in Australia to establish the current state of access to information tools by rural and remote communities and rural health workers in Australia today. It is argued that a suitable telecommunication infrastructure is needed to reach disadvantaged persons in extremely remote areas and that intersectoral support is essential to build this infrastructure. In addition, education will make its utilization possible. PMID:9609497

Lowe, David; Newcombe, Peter; Stumpers, Ben

2013-06-01

Laboratory experimentation is generally considered central to science-based education. Allowing students to "experience" science through various forms of carefully designed practical work, including experimentation, is often claimed to support their learning and motivate their engagement while fulfilling specific curriculum requirements. However, logistical constraints (most especially related to funding) place significant limitations on the ability of schools to provide and maintain high-quality science laboratory experiences and equipment. One potential solution that has recently been the subject of growing interest is the use of remotely accessible laboratories to either supplant, or more commonly to supplement, conventional hands-on laboratories. Remote laboratories allow students and teachers to use high-speed networks, coupled with cameras, sensors, and controllers, to carry out experiments on real physical laboratory apparatus that is located remotely from the student. Research has shown that when used appropriately this can bring a range of potential benefits, including the ability to share resources across multiple institutions, support access to facilities that would otherwise be inaccessible for cost or technical reasons, and provide augmentation of the experimental experience. Whilst there has been considerable work on evaluating the use of remote laboratories within tertiary education, consideration of their role within secondary school science education is much more limited. This paper describes trials of the use of remote laboratories within secondary schools, reporting on the student and teacher reactions to their interactions with the laboratories. The paper concludes that remote laboratories can be highly beneficial, but considerable care must be taken to ensure that their design and delivery address a number of critical issues identified in this paper.

A Prototype Hydrologic Observatory for the Neuse River Basin Using Remote Sensing Data as a Part of the CUAHSI-HIS Effort

NASA Astrophysics Data System (ADS)

Kanwar, R.; Narayan, U.; Lakshmi, V.

2005-12-01

Remote sensing has the potential to immensely advance the science and application of hydrology as it provides multi-scale and multi-temporal measurements of several hydrologic parameters. There is a wide variety of remote sensing data sources available to a hydrologist with a myriad of data formats, access techniques, data quality issues and temporal and spatial extents. It is very important to make data availability and its usage as convenient as possible for potential users. The CUAHSI Hydrologic Information System (HIS) initiative addresses this issue of better data access and management for hydrologists with a focus on in-situ data, that is point measurements of water and energy fluxes which make up the 'more conventional' sources of hydrologic data. This paper explores various sources of remotely sensed hydrologic data available, their data formats and volumes, current modes of data acquisition by end users, metadata associated with data itself, and requirements from potential data models that would allow a seamless integration of remotely sensed hydrologic observations into the Hydrologic Information System. Further, a prototype hydrologic observatory (HO) for the Neuse River Basin is developed using surface temperature, vegetation indices and soil moisture estimates available from remote sensing. The prototype (HO) uses the CUAHSI digital library system (DLS) on the back (server) end. On the front (client) end, a rich visual environment has been developed in order to provide better decision making tools in order to make an optimal choice in the selection of remote sensing data for a particular application. An easy point and click interface to the remote sensing data is also implemented for common users who are just interested in location based query of hydrologic variable values.

Remote Data Exploration with the Interactive Data Language (IDL)

NASA Technical Reports Server (NTRS)

Galloy, Michael

2013-01-01

A difficulty for many NASA researchers is that often the data to analyze is located remotely from the scientist and the data is too large to transfer for local analysis. Researchers have developed the Data Access Protocol (DAP) for accessing remote data. Presently one can use DAP from within IDL, but the IDL-DAP interface is both limited and cumbersome. A more powerful and user-friendly interface to DAP for IDL has been developed. Users are able to browse remote data sets graphically, select partial data to retrieve, import that data and make customized plots, and have an interactive IDL command line session simultaneous with the remote visualization. All of these IDL-DAP tools are usable easily and seamlessly for any IDL user. IDL and DAP are both widely used in science, but were not easily used together. The IDL DAP bindings were incomplete and had numerous bugs that prevented their serious use. For example, the existing bindings did not read DAP Grid data, which is the organization of nearly all NASA datasets currently served via DAP. This project uniquely provides a fully featured, user-friendly interface to DAP from IDL, both from the command line and a GUI application. The DAP Explorer GUI application makes browsing a dataset more user-friendly, while also providing the capability to run user-defined functions on specified data. Methods for running remote functions on the DAP server were investigated, and a technique for accomplishing this task was decided upon.

In contrast to traditional 'video conferencing' the Access Grid (AG), developed by Argonne National Laboratory, is a collaboration of audio, video and shared application tools which provide the 'persistent presence' of each participant. Among the shared application tools are the ability to share viewing and control of presentations, browsers, images and movies. When used in conjunction with Virtual Network Computing (VNC) software, an investigator can interact with colleagues at a remote site, and control remote systems via local keyboard and mouse commands. This combination allows for effective viewing and discussion of information, i.e. data, images, and results. It is clear that such an approach when applied to the medical sciences will provide a means by which a team of experts can not only access, but interact and control medical devices for the purpose of experimentation, diagnosis, surgery and therapy. We present the development of an application node at our 4.7 Tesla MR magnet facility, and a demonstration of remote investigator control of the magnet. A local magnet operator performs manual tasks such as loading the test subject into the magnet and administering the stimulus associated with the functional MRI study. The remote investigator has complete control of the magnet console. S/he can adjust the gradient coil settings, the pulse sequence, image capture frequency, etc. A geographically distributed audience views and interacts with the remote investigator and local MR operator. This AG demonstration of MR magnet control illuminates the potential of untethered medical experiments, procedures and training.

Accessing and Utilizing Remote Sensing Data for Vectorborne Infectious Diseases Surveillance and Modeling

NASA Technical Reports Server (NTRS)

Kiang, Richard; Adimi, Farida; Kempler, Steven

2008-01-01

Background: The transmission of vectorborne infectious diseases is often influenced by environmental, meteorological and climatic parameters, because the vector life cycle depends on these factors. For example, the geophysical parameters relevant to malaria transmission include precipitation, surface temperature, humidity, elevation, and vegetation type. Because these parameters are routinely measured by satellites, remote sensing is an important technological tool for predicting, preventing, and containing a number of vectorborne infectious diseases, such as malaria, dengue, West Nile virus, etc. Methods: A variety of NASA remote sensing data can be used for modeling vectorborne infectious disease transmission. We will discuss both the well known and less known remote sensing data, including Landsat, AVHRR (Advanced Very High Resolution Radiometer), MODIS (Moderate Resolution Imaging Spectroradiometer), TRMM (Tropical Rainfall Measuring Mission), ASTER (Advanced Spaceborne Thermal Emission and Reflection Radiometer), EO-1 (Earth Observing One) ALI (Advanced Land Imager), and SIESIP (Seasonal to Interannual Earth Science Information Partner) dataset. Giovanni is a Web-based application developed by the NASA Goddard Earth Sciences Data and Information Services Center. It provides a simple and intuitive way to visualize, analyze, and access vast amounts of Earth science remote sensing data. After remote sensing data is obtained, a variety of techniques, including generalized linear models and artificial intelligence oriented methods, t 3 can be used to model the dependency of disease transmission on these parameters. Results: The processes of accessing, visualizing and utilizing precipitation data using Giovanni, and acquiring other data at additional websites are illustrated. Malaria incidence time series for some parts of Thailand and Indonesia are used to demonstrate that malaria incidences are reasonably well modeled with generalized linear models and artificial intelligence based techniques. Conclusions: Remote sensing data relevant to the transmission of vectorborne infectious diseases can be conveniently accessed at NASA and some other websites. These data are useful for vectorborne infectious disease surveillance and modeling.

Remote nursing certified practice: viewing nursing and nurse practitioner practice through a social justice lens.

Remote Nursing Certified Practice (RNCP) was introduced in 2010 to regulate nursing practice in remote, largely First Nations communities in British Columbia, Canada. These are communities that often experience profound health and health-care inequities. Typically nurses are the main health-care providers. Using a critical social justice lens, the authors explore the clinical and ethical implications of RNCP in terms of access to equitable, high-quality primary health care.They examine the fit between the level and scope of health services provided by registered nurses working under RNCP and the health needs of remote First Nations communities. In doing so, they draw comparisons between nurse practitioners (NPs) and outpost nurses working in NP roles who historically were employed to provide health care in these communities.The authors conclude by calling for nursing regulations that support equitable, high-quality primary care for all British Columbians.

Toward the improvement of trail classification in national parks using the recreation opportunity spectrum approach.

PubMed

Oishi, Yoshitaka

2013-06-01

Trail settings in national parks are essential management tools for improving both ecological conservation efforts and the quality of visitor experiences. This study proposes a plan for the appropriate maintenance of trails in Chubusangaku National Park, Japan, based on the recreation opportunity spectrum (ROS) approach. First, we distributed 452 questionnaires to determine park visitors' preferences for setting a trail (response rate = 68 %). Respondents' preferences were then evaluated according to the following seven parameters: access, remoteness, naturalness, facilities and site management, social encounters, visitor impact, and visitor management. Using nonmetric multidimensional scaling and cluster analysis, the visitors were classified into seven groups. Last, we classified the actual trails according to the visitor questionnaire criteria to examine the discrepancy between visitors' preferences and actual trail settings. The actual trail classification indicated that while most developed trails were located in accessible places, primitive trails were located in remote areas. However, interestingly, two visitor groups seemed to prefer a well-conserved natural environment and, simultaneously, easily accessible trails. This finding does not correspond to a premise of the ROS approach, which supposes that primitive trails should be located in remote areas without ready access. Based on this study's results, we propose that creating trails, which afford visitors the opportunity to experience a well-conserved natural environment in accessible areas is a useful means to provide visitors with diverse recreation opportunities. The process of data collection and analysis in this study can be one approach to produce ROS maps for providing visitors with recreational opportunities of greater diversity and higher quality.

Injury rates and injury mortality rates are generally higher in rural and remote communities compared with urban jurisdictions as has been shown to be the case in the rural-remote area of Northwest (NW) British Columbia (BC). The purpose of study was to identify: (1) the place and timing of death following injury in NW BC, (2) access to and quality of local trauma services, and (3) opportunities to improve trauma outcomes. Quantitative data from demographic and geographic databases, the BC Trauma Registry, Hospital discharge abstract database, and the BC Coroner's Office, along with qualitative data from chart reviews of selected major trauma cases, and interviews with front-line trauma care providers were collated and analyzed for patients sustaining injury in NW BC from April 2001 to March 2006. The majority of trauma deaths (82%) in NW BC occur prehospital. Patients arriving alive to NW hospitals have low hospital mortality (1.0%), and patients transferring from NW BC to tertiary centers have better outcomes than matched patients achieving direct entry into the tertiary center by way of geographic proximity. Access to local trauma services was compromised by: incident discovery, limited phone service (land lines/cell), incomplete 911 emergency medical services system access, geographical and climate challenges compounded by limited transportation options, airport capabilities and paramedic training level, dysfunctional hospital no-refusal policies, lack of a hospital destination policies, and lack of system leadership and coordination. Improving trauma outcomes in this rural-remote jurisdiction requires a systems approach to address root causes of delays in access to care, focusing on improved access to emergency medical services, hospital bypass and destination protocols, improved transportation options, advanced life support transfer capability, and designated, coordinated local trauma services.

Objective To quantify total provider fees, benefits paid by the Australian Government and out-of-pocket patients' costs of mental health Medicare Benefits Schedule (MBS) consultations provided to women in the perinatal period (pregnancy to end of the first postnatal year). Method A retrospective study of MBS utilisation and costs (in 2011-12 A$) for women giving birth between 2006 and 2010 by state, provider-type, and geographic remoteness was undertaken. Results The cost of mental health consultations during the perinatal period was A$17.5million for women giving birth in 2007, rising to A$29million in 2010. Almost 9% of women giving birth in 2007 had a mental health consultation compared with more than 14% in 2010. An increase in women accessing consultations, along with an increase in the average number of consultations received, were the main drivers of the increased cost, with costs per service remaining stable. There was a shift to non-specialist care and bulk billing rates increased from 44% to 52% over the study period. In 2010, the average total cost (provider fees) per woman accessing mental health consultations during the perinatal period was A$689, and the average cost per service was A$133. Compared with women residing in regional and remote areas, women residing in major cities where more likely to access consultations, and these were more likely to be with a psychiatrist rather than an allied health professional or general practitioner. Conclusion Increased access to mental health consultations has coincided with the introduction of recent mental health initiatives, however disparities exist based on geographic location. This detailed cost analysis identifies inequities of access to perinatal mental health services in regional and remote areas and provides important data for economic and policy analysis of future mental health initiatives. What is known about the topic? The mental healthcare landscape in Australia has changed significantly over the last decade, with the introduction of numerous policies aimed at prevention, screening and improving access to treatment. Several of these policies have been aimed at perinatal depression, which affects 15% of women giving birth. What does this paper add? This is the first population-based, cost analysis of mental health consultations during the perinatal period (pregnancy to end of the first postnatal year) in Australia. Almost 9% of women giving birth in 2007 had a mental health consultation funded though the MBS, compared with more than 14% in 2010. Over the same period there was a shift from psychiatric consultations to allied health and primary care consultations. In 2010, the total cost (provider fee) of these consultations was A$29million, equating to an average cost per woman of A$689 and A$133 per service. Despite the changing policy environment, significant disparities exist in access to care according to geographic remoteness. What are the implications for practitioners? Recent policy initiatives have resulted in increasing access to mental health consultations for women around the time of childbirth. However, policies are needed that target women outside of major cities. Furthermore, evidence is needed on whether the increase in access has resulted in improved mental health outcomes for women at this vulnerable time. The cost data provided by this study are unique and will inform future mental health policy development and health economic evaluations.

Web-based interactive access, analysis and comparison of remotely sensed and in situ measured temperature data

2014-05-01

Numerous datasets providing temperature information from meteorological stations or remote sensing satellites are available. However, the challenging issue is to search in the archives and process the time series information for further analysis. These steps can be automated for each individual product, if the pre-conditions are complied, e.g. data access through web services (HTTP, FTP) or legal rights to redistribute the datasets. Therefore a python-based package was developed to provide data access and data processing tools for MODIS Land Surface Temperature (LST) data, which is provided by NASA Land Processed Distributed Active Archive Center (LPDAAC), as well as the Global Surface Summary of the Day (GSOD) and the Global Historical Climatology Network (GHCN) daily datasets provided by NOAA National Climatic Data Center (NCDC). The package to access and process the information is available as web services used by an interactive web portal for simple data access and analysis. Tools for time series analysis were linked to the system, e.g. time series plotting, decomposition, aggregation (monthly, seasonal, etc.), trend analyses, and breakpoint detection. Especially for temperature data a plot was integrated for the comparison of two temperature datasets based on the work by Urban et al. (2013). As a first result, a kernel density plot compares daily MODIS LST from satellites Aqua and Terra with daily means from GSOD and GHCN datasets. Without any data download and data processing, the users can analyze different time series datasets in an easy-to-use web portal. As a first use case, we built up this complimentary system with remotely sensed MODIS data and in situ measurements from meteorological stations for Siberia within the Siberian Earth System Science Cluster (www.sibessc.uni-jena.de).

Background With a dramatic increase in mobile phone use in low- and middle-income countries, mobile health (mHealth) has great potential to connect health care services directly to participants enrolled and improve engagement of care. Rural and remote global settings may pose both significant challenges and opportunities. Objective The objective of our study was to understand the demographics, phone usage and ownership characteristics, and feasibility among patients in rural and remote areas of Kenya of having text messaging (short messaging service, SMS)-based mHealth intervention for improvements in antenatal care attendance and routine immunization among children in Northern Kenya. Methods A survey-based descriptive study was conducted between October 2014 and February 2015 at 8 health facilities in Northern Kenya as part of a program to scale up an mHealth service in rural and remote regions. The study was conducted at 6 government health facilities in Isiolo, Marsabit, and Samburu counties in remote and northern arid lands (NAL). Two less remote health facilities in Laikipia and Meru counties in more populated central highlands were included as comparison sites. Results A total of 284 participants were surveyed; 63.4% (180/284) were from NAL clinics, whereas 36.6% (104/284) were from adjacent central highland clinics. In the NAL, almost half (48.8%, 88/180) reported no formal education and 24.4% (44/180) self-identified as nomads. The majority of participants from both regions had access to mobile phone: 99.0% (103/104) of participants from central highlands and 82.1% (147/180) of participants from NAL. Among those who had access to a phone, there were significant differences in network challenges and technology literacy between the 2 regions. However, there was no significant difference in the proportion of participants from NAL and central highlands who indicated that they would like to receive a weekly SMS text message from their health care provider (90.0% vs 95.0%; P=.52). Overall, 92.0% (230/250) of participants who had access to a telephone said that they would like to receive a weekly SMS text message from their health care provider. Most phone users already spent the equivalent of 626 SMS text messages on mobile credit for personal use. Conclusions Despite the remoteness of northern Kenya’s NAL, the results indicate that the majority of pregnant women or care givers attending the maternal, newborn, and child health clinics have access to mobile phone and would like to receive text messages from their health care provider. mHealth programs, if designed appropriately for these settings, may be an innovative way for engaging women in care for improved maternal and newborn child health outcomes in order to achieve sustainable development goals.

Health promotion is a key component of comprehensive primary health care. Health promotion approaches complement healthcare management by enabling individuals to increase control over their health. Many primary healthcare staff have a role to play in health promotion practice, but their ability to integrate health promotion into practice is influenced by their previous training and experience. For primary healthcare staff working in rural and remote locations, access to professional development can be limited by what is locally available and prohibitive in terms of cost for travel and accommodation. This study provides insight into how staff at a large north Queensland Aboriginal community controlled health service access skill development and health promotion expertise to support their work. A qualitative exploratory study was conducted. Small group and individual semi-structured interviews were conducted with staff at Apunipima Cape York Health Council (n=9). A purposive sampling method was used to recruit participants from a number of primary healthcare teams that were more likely to be involved in health promotion work. Both on-the-ground staff and managers were interviewed. All participants were asked how they access skill development and expertise in health promotion practice and what approaches they prefer for ongoing health promotion support. The interviews were transcribed verbatim and analysed thematically. All participants valued access to skill development, advice and support that would assist their health promotion practice. Skill development and expertise in health promotion was accessed from a variety of sources: conferences, workshops, mentoring or shared learning from internal and external colleagues, and access to online information and resources. With limited funds and limited access to professional development locally, participants fostered external and internal organisational relationships to seek in-kind advice and support. Irrespective of where the advice came from, it needed to be applicable to work with Aboriginal and Torres Strait Islander remote communities. To improve health outcomes in rural and remote communities, the focus on health promotion and prevention approaches must be strengthened. Primary healthcare staff require ongoing access to health promotion skill development and expertise to increase their capacity to deliver comprehensive primary health care. Practice-based evidence from staff working in the field provides a greater understanding of how skill development and advice are accessed. Many of these strategies can be formalised through organisational plans and systems, which would ensure that a skilled health promotion workforce is sustained.

Schlabach, David M.

2005-01-01

The increased dependency on the World Wide Web by both laboratories and their customers has led LIMS developers to take advantage of thin-client web applications that provide both remote data entry and manipulation, along with remote reporting functionality. Use of an LIMS through a web browser allows a person to interact with a distant application, providing both remote administration and real-time analytical result delivery from virtually anywhere in the world. While there are many benefits of web-based LIMS applications, some concern must be given to these new methods of system architecture before justifying them as a suitable replacement for their traditional client-server systems. Developers and consumers alike must consider the security aspects of introducing a wide area network capable system into a production environment, as well as the concerns of data integrity and usability.

Omala, Anyembe Andrew; Kibiwott, Kittur P; Li, Fagen

Wireless body area network (WBAN) provide a mechanism of transmitting a persons physiological data to application providers e.g. hospital. Given the limited range of connectivity associated with WBAN, an intermediate portable device e.g. smartphone, placed within WBAN's connectivity, forwards the data to a remote server. This data, if not protected from an unauthorized access and modification may be lead to poor diagnosis. In order to ensure security and privacy between WBAN and a server at the application provider, several authentication schemes have been proposed. Recently, Wang and Zhang proposed an authentication scheme for WBAN using bilinear pairing. However, in their scheme, an application provider could easily impersonate a client. In order to overcome this weakness, we propose an efficient remote authentication scheme for WBAN. In terms of performance, our scheme can not only provide a malicious insider security, but also reduce running time of WBAN (client) by 51 % as compared to Wang and Zhang scheme.

Park, Chung Hyuk; Ryu, Eun-Seok; Howard, Ayanna M

2015-01-01

This paper presents a haptic telepresence system that enables visually impaired users to explore locations with rich visual observation such as art galleries and museums by using a telepresence robot, a RGB-D sensor (color and depth camera), and a haptic interface. The recent improvement on RGB-D sensors has enabled real-time access to 3D spatial information in the form of point clouds. However, the real-time representation of this data in the form of tangible haptic experience has not been challenged enough, especially in the case of telepresence for individuals with visual impairments. Thus, the proposed system addresses the real-time haptic exploration of remote 3D information through video encoding and real-time 3D haptic rendering of the remote real-world environment. This paper investigates two scenarios in haptic telepresence, i.e., mobile navigation and object exploration in a remote environment. Participants with and without visual impairments participated in our experiments based on the two scenarios, and the system performance was validated. In conclusion, the proposed framework provides a new methodology of haptic telepresence for individuals with visual impairments by providing an enhanced interactive experience where they can remotely access public places (art galleries and museums) with the aid of haptic modality and robotic telepresence.

This paper presents a unique virtual reality training and assessment tool developed under a NASA grant, "Research in Human Factors Aspects of Enhanced Virtual Environments for Extravehicular Activity (EVA) Training and Simulation." The Remote Access Virtual Environment Network (RAVEN) was created to train and evaluate the verbal, mental and physical coordination required between the intravehicular (IVA) astronaut operating the Remote Manipulator System (RMS) arm and the EVA astronaut standing in foot restraints on the end of the RMS. The RAVEN system currently allows the EVA astronaut to approach the Hubble Space Telescope (HST) under control of the IVA astronaut and grasp, remove, and replace the Wide Field Planetary Camera drawer from its location in the HST. Two viewpoints, one stereoscopic and one monoscopic, were created all linked by Ethernet, that provided the two trainees with the appropriate training environments.

Spatiotemporal data, especially remote sensing data, are widely used in ecological, geographical, agriculture, and military research and applications. With the development of remote sensing technology, more and more remote sensing data are accumulated and stored in the cloud. An effective way for cloud users to access and analyse these massive spatiotemporal data in the web clients becomes an urgent issue. In this paper, we proposed a new scalable, interactive and web-based cloud computing solution for massive remote sensing data analysis. We build a spatiotemporal analysis platform to provide the end-user with a safe and convenient way to access massive remote sensing data stored in the cloud. The lightweight cloud storage system used to store public data and users' private data is constructed based on open source distributed file system. In it, massive remote sensing data are stored as public data, while the intermediate and input data are stored as private data. The elastic, scalable, and flexible cloud computing environment is built using Docker, which is a technology of open-source lightweight cloud computing container in the Linux operating system. In the Docker container, open-source software such as IPython, NumPy, GDAL, and Grass GIS etc., are deployed. Users can write scripts in the IPython Notebook web page through the web browser to process data, and the scripts will be submitted to IPython kernel to be executed. By comparing the performance of remote sensing data analysis tasks executed in Docker container, KVM virtual machines and physical machines respectively, we can conclude that the cloud computing environment built by Docker makes the greatest use of the host system resources, and can handle more concurrent spatial-temporal computing tasks. Docker technology provides resource isolation mechanism in aspects of IO, CPU, and memory etc., which offers security guarantee when processing remote sensing data in the IPython Notebook. Users can write complex data processing code on the web directly, so they can design their own data processing algorithm.

To examine whether adult use of mental health services subsidised by Medicare varies by measures of socioeconomic and geographic disadvantage in Australia. A secondary analysis of national Medicare data from 1 July 2007 to 30 June 2011 for all mental health services subsidised by Better Access to Mental Health Care (Better Access) and Medicare - providers included general practitioners, psychiatrists, clinical psychologists and mental health allied health practitioners. Service use rates followed by measurement of inequity using the concentration curve and concentration index. Increasing remoteness was consistently associated with lower service activity; eg, per 1000 population, the annual rate of use of GP items was 79 in major cities and 25 and 8 in remote and very remote areas, respectively. Apart from GP usage, higher socioeconomic disadvantage in areas was typically associated with lower usage; eg, per 1000 population per year, clinical psychologist consultations were 68, 40 and 23 in the highest, middle and lowest advantaged quintiles, respectively; and non-Better Access psychiatry items were 117, 55 and 45 in the highest, middle and lowest advantaged quintiles, respectively. Our results highlight important socioeconomic and geographical disparities associated with the use of Better Access and related Medicare services. This can inform Australia's policymakers about these priority gaps and help to stimulate targeted strategies both nationally and regionally that work towards the universal and equitable delivery of mental health care for all Australians.

The REMOT (Remote Experiment Monitoring and conTrol) project was financed by 1996 by the European Community in order to investigate the possibility of generalizing the remote access to scientific instruments. After the feasibility of this idea was demonstrated, the DYNACORE (DYNAmically, COnfigurable Remote Experiment monitoring and control) project was initiated as a REMOT follow-up. Its purpose is to develop software technology to support scientists in two different domains, astronomy and plasma physics. The resulting system allows (1) simultaneous multiple user access to different experimental facilities, (2) dynamic adaptability to different kinds of real instruments, (3) exploitation of the communication infrastructures features, (4) ease of use through intuitive graphical interfaces, and (5) additional inter-user communication using off-the-shelf projects such as video-conference tools, chat programs and shared blackboards.

A laboratory is an essential equipment for engineering students to do a useful practical work. Therefore, universities should provide an adequate facility for practical work. On the other hand, industrial automation laboratory would offer students beneficial experience by using various educational PLC kits. This paper describes the development of Web-based Programmable Logic Controller (PLC) remote laboratory called RLab. It provides an environment for learners to study PLC application to control the level of the non-interacting tank. The RLab architecture is based on a Moodle and Remote Desktop, which also manages the booking system of the schedule of practical work in the laboratory. The RLab equipped by USB cameras providing a real-time view of PLC environment. To provide a secured system, the RLab combines Moodle and Remote Desktop application for the authentication system and management of remote users. Moodle will send PartnerID and password to connect to TeamViewer. It has been examined that the laboratory requirement, time and flexibility restrictions constitute a significant obstacle facing traditional students desiring to finish the course. A remote access laboratory can be eliminating time and flexibility restrictions. The preliminary study of RLab usability proved that such system is adequate to give the learners a distance practical work environment.

The ESA GlobPermafrost (www.globpermafrost.info) provides a remote sensing service for permafrost research and applications. The service comprises of data product generation for various sites and regions as well as specific infrastructure allowing overview and access to datasets. Based on an online user survey conducted within the project, the user community extensively applies GIS software to handle remote sensing-derived datasets and requires preview functionalities before accessing them. In response, we develop the Permafrost Information System PerSys which is conceptualized as an open access geospatial data dissemination and visualization portal. PerSys will allow visualisation of GlobPermafrost raster and vector products such as land cover classifications, Landsat multispectral index trend datasets, lake and wetland extents, InSAR-based land surface deformation maps, rock glacier velocity fields, spatially distributed permafrost model outputs, and land surface temperature datasets. The datasets will be published as WebGIS services relying on OGC-standardized Web Mapping Service (WMS) and Web Feature Service (WFS) technologies for data display and visualization. The WebGIS environment will be hosted at the AWI computing centre where a geodata infrastructure has been implemented comprising of ArcGIS for Server 10.4, PostgreSQL 9.2 and a browser-driven data viewer based on Leaflet (http://leafletjs.com). Independently, we will provide an `Access - Restricted Data Dissemination Service', which will be available to registered users for testing frequently updated versions of project datasets. PerSys will become a core project of the Arctic Permafrost Geospatial Centre (APGC) within the ERC-funded PETA-CARB project (www.awi.de/petacarb). The APGC Data Catalogue will contain all final products of GlobPermafrost, allow in-depth dataset search via keywords, spatial and temporal coverage, data type, etc., and will provide DOI-based links to the datasets archived in the long-term, open access PANGAEA data repository.

A security architecture for interconnecting health information systems.

Several hereditary and other chronic diseases necessitate continuous and complicated health care procedures, typically offered in different, often distant, health care units. Inevitably, the medical records of patients suffering from such diseases become complex, grow in size very fast and are scattered all over the units involved in the care process, hindering communication of information between health care professionals. Web-based electronic medical records have been recently proposed as the solution to the above problem, facilitating the interconnection of the health care units in the sense that health care professionals can now access the complete medical record of the patient, even if it is distributed in several remote units. However, by allowing users to access information from virtually anywhere, the universe of ineligible people who may attempt to harm the system is dramatically expanded, thus severely complicating the design and implementation of a secure environment. This paper presents a security architecture that has been mainly designed for providing authentication and authorization services in web-based distributed systems. The architecture has been based on a role-based access scheme and on the implementation of an intelligent security agent per site (i.e. health care unit). This intelligent security agent: (a). authenticates the users, local or remote, that can access the local resources; (b). assigns, through temporary certificates, access privileges to the authenticated users in accordance to their role; and (c). communicates to other sites (through the respective security agents) information about the local users that may need to access information stored in other sites, as well as about local resources that can be accessed remotely.

Little is published about the health issues of traditional communities in the remote Peruvian Amazon. This study assessed healthcare access, health perceptions, and beliefs of the indigenous population along the Ampiyacu and Yaguasyacu rivers in north-eastern Peru. One hundred and seventy-nine adult inhabitants of 10 remote settlements attending health clinics were interviewed during a medical services trip in April 2012. Demographics, health status, access to healthcare, health education, sanitation, alcohol use, and smoke exposure were recorded. Our findings indicate that poverty, household overcrowding, and poor sanitation remain commonplace in this group. Furthermore, there are poor levels of health education and on-going barriers to accessing healthcare. Healthcare access and health education remain poor in the remote Peruvian Amazon. This combined with poverty and its sequelae render this population vulnerable to disease. PMID:24277789

Health systems are increasingly implementing remote telephone and Internet refill systems to enhance patient access to medication refills. Remote refill systems may provide an effective approach for improving medication non-adherence, but more research is needed among patients with limited English proficiency with poor access to remote refill systems. To compare the use of remote medication refill systems among limited-English-proficiency (LEP) and English-proficient (EP) patients with chronic conditions. Cross-sectional survey in six languages/dialects (English, Cantonese, Mandarin, Korean, Vietnamese, and Spanish) of 509 adults with diabetes, hypertension, or hyperlipidemia. Primary study outcomes were self-reported use of 1) Internet refills, 2) telephone refills, and 3) any remote refill system. LEP was measured by patient self-identification of a primary language other than English and a claims record of use of an interpreter. Other measures were age, gender, education, years in the U.S., insurance, health status, chronic conditions, and number of prescribed medications. Analyses included multivariable logistic regression weighted for survey non-response. Overall, 33.1 % of patients refilled their medications by telephone and 31.6 % by Internet. Among LEP patients (n = 328), 31.5 % refilled by telephone and 21.2 % by Internet, compared with 36.7 % by telephone and 52.7 % by Internet among EP patients (n = 181). Internet refill by language groups were as follows: English (52.7 %), Cantonese (34.9 %), Mandarin (17.4 %), Korean (16.7 %), Vietnamese (24.4 %), and Spanish (12.6 %). Compared to EP patients, LEP patients had lower use of any remote refill system (adjusted odds ratio [AOR] 0.18; p < 0.001), CONCLUSIONS: LEP patients are significantly less likely than EP patients to use any remote medication refill system. Increased reliance on current systems for remote medication refills may increase disparities in health outcomes affecting LEP patients with poor access to telephone and Internet medication refills.

OurOcean Portal 2.0 (http:// ourocean.jpl.nasa.gov) is a software system designed to enable users to easily gain access to ocean observation data, both remote-sensing and in-situ, configure and run an Ocean Model with observation data assimilated on a remote computer, and visualize both the observation data and the model outputs. At present, the observation data and models focus on the California coastal regions and Prince William Sound in Alaska. This system can be used to perform both real-time and retrospective analyses of remote-sensing data and model outputs. OurOcean Portal 2.0 incorporates state-of-the-art information technologies (IT) such as MySQL database, Java Web Server (Apache/Tomcat), Live Access Server (LAS), interactive graphics with Java Applet at the Client site and MatLab/GMT at the server site, and distributed computing. OurOcean currently serves over 20 real-time or historical ocean data products. The data are served in pre-generated plots or their native data format. For some of the datasets, users can choose different plotting parameters and produce customized graphics. OurOcean also serves 3D Ocean Model outputs generated by ROMS (Regional Ocean Model System) using LAS. The Live Access Server (LAS) software, developed by the Pacific Marine Environmental Laboratory (PMEL) of the National Oceanic and Atmospheric Administration (NOAA), is a configurable Web-server program designed to provide flexible access to geo-referenced scientific data. The model output can be views as plots in horizontal slices, depth profiles or time sequences, or can be downloaded as raw data in different data formats, such as NetCDF, ASCII, Binary, etc. The interactive visualization is provided by graphic software, Ferret, also developed by PMEL. In addition, OurOcean allows users with minimal computing resources to configure and run an Ocean Model with data assimilation on a remote computer. Users may select the forcing input, the data to be assimilated, the simulation period, and the output variables and submit the model to run on a backend parallel computer. When the run is complete, the output will be added to the LAS server for

From Ions to Bits - Developing the IT infrastructure around the CAMECA IMS 1280-HR SIMS lab at GFZ Potsdam

Secondary Ion Mass Spectrometers (SIMS) is an highly sensitive technique for analyzing the surfaces of solids and thin film samples, but has the major drawback that such instruments are both rare and expensive. The Virtual SIMS project aims to design, develop and operate the IT infrastructure around the CAMECA IMS 1280-HR SIMS at GFZ Potsdam. The system will cover the whole spectrum of the procedures in the lab - from the online application for measurement time, to the remote access to the instrument and finally the maintenance of the data for publishing and future re-use. A virtual lab infrastructure around the IMS 1280 will enable remote access to the instrument and make measurement time available to the broadest possible user community. Envisioned is that the IT infrastructure would consist of the following: web portal, data repository, sample repository, project management software, communication arrangements between the lab staff and distant researcher and remote access to the instruments. The web portal will handle online applications for the measurement time. The data from the experiments, the monitoring sensor logs and the lab logbook entries are to be stored and archived. Researchers will be able to access their data remotely in real time, thus imposing a user rights management strucuture. Also planned is that all samples and the standards will be assigned a unique International GeoSample Number (IGSN) and that the images of the samples will be stored and made accessible in addition to any additional documents which might be uploaded by the researcher. The project management application will schedule the application process, the measurements times, notifications and alerts. A video conference capability is forseen for communication between the Potsdam staff and the remote researcher. The remote access to the instruments requires a sophisticated client-server solution. This highly sensitive instrument has to be controlled in real-time with latencies diminished to a minimum. Also, failures and shortages of the internet connection, as well as possible outages on the client side, have to be considered and safe fallbacks for such events must be provided. The level of skills of the researcher remotely operating the instrument will define the scope of control given during an operating session. An important aspect of the project is the design of the virtual lab system in collaboration with the laboratory operators and the researchers who will use the instrument and its peripherals. Different approaches for the IT solutions will be tested and evaluated, so imporved guidelines can evolve from obsperved operating performance.

2001-01-01

Many scientific applications in aerodynamics and solid mechanics are written in Fortran. Refitting these legacy Fortran codes with distributed objects can increase the code reusability. The remote variable scheme provided in NPSS/CCDK helps programmers easily migrate the Fortran codes towards a client-server platform. This scheme gives the client the capability of accessing the variables at the server site. In this paper, we review and enhance the remote variable scheme by using the operator overloading features in C++. The enhancement enables NPSS programmers to use remote variables in much the same way as traditional variables. The remote variable scheme adopts the lazy update approach and the prefetch method. The design strategies and implementation techniques are described in details. Preliminary performance evaluation shows that communication overhead can be greatly reduced.

The National Satellite Land Remote Sensing Data Archive (NSLRSDA) resides at the U.S. Geological Survey's (USGS) Earth Resources Observation and Science (EROS) Center. Through the Land Remote Sensing Policy Act of 1992, the U.S. Congress directed the Department of the Interior (DOI) to establish a permanent Government archive containing satellite remote sensing data of the Earth's land surface and to make this data easily accessible and readily available. This unique DOI/USGS archive provides a comprehensive, permanent, and impartial observational record of the planet's land surface obtained throughout more than five decades of satellite remote sensing. Satellite-derived data and information products are primary sources used to detect and understand changes such as deforestation, desertification, agricultural crop vigor, water quality, invasive plant species, and certain natural hazards such as flood extent and wildfire scars.

Remotely Delivered Exercise-Based Cardiac Rehabilitation: Design and Content Development of a Novel mHealth Platform.

PubMed

Rawstorn, Jonathan C; Gant, Nicholas; Meads, Andrew; Warren, Ian; Maddison, Ralph

2016-06-24

Participation in traditional center-based cardiac rehabilitation exercise programs (exCR) is limited by accessibility barriers. Mobile health (mHealth) technologies can overcome these barriers while preserving critical attributes of center-based exCR monitoring and coaching, but these opportunities have not yet been capitalized on. We aimed to design and develop an evidence- and theory-based mHealth platform for remote delivery of exCR to any geographical location. An iterative process was used to design and develop an evidence- and theory-based mHealth platform (REMOTE-CR) that provides real-time remote exercise monitoring and coaching, behavior change education, and social support. The REMOTE-CR platform comprises a commercially available smartphone and wearable sensor, custom smartphone and Web-based applications (apps), and a custom middleware. The platform allows exCR specialists to monitor patients' exercise and provide individualized coaching in real-time, from almost any location, and provide behavior change education and social support. Intervention content incorporates Social Cognitive Theory, Self-determination Theory, and a taxonomy of behavior change techniques. Exercise components are based on guidelines for clinical exercise prescription. The REMOTE-CR platform extends the capabilities of previous telehealth exCR platforms and narrows the gap between existing center- and home-based exCR services. REMOTE-CR can complement center-based exCR by providing an alternative option for patients whose needs are not being met. Remotely monitored exCR may be more cost-effective than establishing additional center-based programs. The effectiveness and acceptability of REMOTE-CR are now being evaluated in a noninferiority randomized controlled trial.

Improvement of a Privacy Authentication Scheme Based on Cloud for Medical Environment.

PubMed

Chiou, Shin-Yan; Ying, Zhaoqin; Liu, Junqiang

2016-04-01

Medical systems allow patients to receive care at different hospitals. However, this entails considerable inconvenience through the need to transport patients and their medical records between hospitals. The development of Telecare Medicine Information Systems (TMIS) makes it easier for patients to seek medical treatment and to store and access medical records. However, medical data stored in TMIS is not encrypted, leaving patients' private data vulnerable to external leaks. In 2014, scholars proposed a new cloud-based medical information model and authentication scheme which would not only allow patients to remotely access medical services but also protects patient privacy. However, this scheme still fails to provide patient anonymity and message authentication. Furthermore, this scheme only stores patient medical data, without allowing patients to directly access medical advice. Therefore, we propose a new authentication scheme, which provides anonymity, unlinkability, and message authentication, and allows patients to directly and remotely consult with doctors. In addition, our proposed scheme is more efficient in terms of computation cost. The proposed system was implemented in Android system to demonstrate its workability.

1996-01-01

The Planetary Data System Imaging Node maintains and distributes the archives of planetary image data acquired from NASA's flight projects with the primary goal of enabling the science community to perform image processing and analysis on the data. The Node provides direct and easy access to the digital image archives through wide distribution of the data on CD-ROM media and on-line remote-access tools by way of Internet services. The Node provides digital image processing tools and the expertise and guidance necessary to understand the image collections. The data collections, now approaching one terabyte in volume, provide a foundation for remote sensing studies for virtually all the planetary systems in our solar system (except for Pluto). The Node is responsible for restoring data sets from past missions in danger of being lost. The Node works with active flight projects to assist in the creation of their archive products and to ensure that their products and data catalogs become an integral part of the Node's data collections.

2003-07-01

Ultrasonic Doppler color imaging can provide anatomic information and simultaneously render flow information within blood vessels for diagnostic purpose. Many researchers are currently developing ultrasound image processing algorithms in order to provide physicians with accurate clinical parameters from the images. Because researchers use a variety of computer languages and work on different computer platforms to implement their algorithms, it is difficult for other researchers and physicians to access those programs. A system has been developed using World Wide Web (WWW) technologies and HTTP communication protocols to publish our ultrasonic Angle Independent Doppler Color Image (AIDCI) processing algorithm and several general measurement tools on the Internet, where authorized researchers and physicians can easily access the program using web browsers to carry out remote analysis of their local ultrasonic images or images provided from the database. In order to overcome potential incompatibility between programs and users' computer platforms, ActiveX technology was used in this project. The technique developed may also be used for other research fields.

With a dramatic increase in mobile phone use in low- and middle-income countries, mobile health (mHealth) has great potential to connect health care services directly to participants enrolled and improve engagement of care. Rural and remote global settings may pose both significant challenges and opportunities. The objective of our study was to understand the demographics, phone usage and ownership characteristics, and feasibility among patients in rural and remote areas of Kenya of having text messaging (short messaging service, SMS)-based mHealth intervention for improvements in antenatal care attendance and routine immunization among children in Northern Kenya. A survey-based descriptive study was conducted between October 2014 and February 2015 at 8 health facilities in Northern Kenya as part of a program to scale up an mHealth service in rural and remote regions. The study was conducted at 6 government health facilities in Isiolo, Marsabit, and Samburu counties in remote and northern arid lands (NAL). Two less remote health facilities in Laikipia and Meru counties in more populated central highlands were included as comparison sites. A total of 284 participants were surveyed; 63.4% (180/284) were from NAL clinics, whereas 36.6% (104/284) were from adjacent central highland clinics. In the NAL, almost half (48.8%, 88/180) reported no formal education and 24.4% (44/180) self-identified as nomads. The majority of participants from both regions had access to mobile phone: 99.0% (103/104) of participants from central highlands and 82.1% (147/180) of participants from NAL. Among those who had access to a phone, there were significant differences in network challenges and technology literacy between the 2 regions. However, there was no significant difference in the proportion of participants from NAL and central highlands who indicated that they would like to receive a weekly SMS text message from their health care provider (90.0% vs 95.0%; P=.52). Overall, 92.0% (230/250) of participants who had access to a telephone said that they would like to receive a weekly SMS text message from their health care provider. Most phone users already spent the equivalent of 626 SMS text messages on mobile credit for personal use. Despite the remoteness of northern Kenya's NAL, the results indicate that the majority of pregnant women or care givers attending the maternal, newborn, and child health clinics have access to mobile phone and would like to receive text messages from their health care provider. mHealth programs, if designed appropriately for these settings, may be an innovative way for engaging women in care for improved maternal and newborn child health outcomes in order to achieve sustainable development goals. ©Abdul Momin Kazi, Jason-Louis Carmichael, Galgallo Waqo Hapanna, Patrick Gikaria Wangoo, Sarah Karanja, Denis Wanyama, Samuel Opondo Muhula, Lennie Bazira Kyomuhangi, Mores Loolpapit, Gilbert Bwire Wangalwa, Koki Kinagwi, Richard Todd Lester.

The National Collaboratory concept has great potential for enabling 'critical mass' working groups and highly interdisciplinary research projects. We report here on a new program to build a prototype collaboratory using the Sondrestrom Upper Atmospheric Research Facility in Kangerlussuaq, Greenland and a group of associated scientists. The Upper Atmospheric Research Collaboratory (UARC) is a joint venture of researchers in upper atmospheric and space science, computer science, and behavioral science to develop a testbed for collaborative remote research. We define the 'collaboratory' as an advanced information technology environment which enables teams to work together over distance and time on a wide variety of intellectual tasks. It provides: (1) human-to-human communications using shared computer tools and work spaces; (2) group access and use of a network of information, data, and knowledge sources; and (3) remote access and control of instruments for data acquisition. The UARC testbed is being implemented to support a distributed community of space scientists so that they have network access to the remote instrument facility in Kangerlussuaq and are able to interact among geographically distributed locations. The goal is to enable them to use the UARC rather than physical travel to Greenland to conduct team research campaigns. Even on short notice through the collaboratory from their home institutions, participants will be able to meet together to operate a battery of remote interactive observations and to acquire, process, and interpret the data.

New orientation and accessibility option for persons with visual impairment: transportation applications for remote infrared audible signage.

Crandall, William; Bentzen, Billie Louise; Myers, Linda; Brabyn, John

2001-05-01

BACKGROUND: For a blind or visually impaired person, a vital prerequisite to accessing any feature of the built environment is being able to find this feature. Braille signs, even where available, do not replace the functions of print signage because they cannot be read from a distance. Remotely readable infrared signs utilise spoken infrared message transmissions to label key environmental features, so that a blind person with a suitable receiver can locate and identify them from a distance. METHODS: Three problems that are among the most challenging and dangerous faced by blind travellers are negotiating complex transit stations, locating bus stops and safely and efficiently crossing light-controlled intersections. We report the results of human factors studies using a remote infrared audible sign system (RIAS), Talking Signs(R), in these critical tasks, examining issues such as the amount of training needed to use the system, its impact on performance and safety, benefits for different population subgroups and user opinions of its value. RESULTS: Results are presented in the form of both objective performance measures and in subjects' ratings of the usefulness of the system in performing these tasks. Findings are that blind people can quickly and easily learn to use remote infrared audible signage effectively and that its use improves travel safety, efficiency and independence.? CONCLUSIONS: The technology provides equal access to a wide variety of public facilities.

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

Wireless physiological signal monitoring system designing with secured data communication in the health care system is an important and dynamic process. We propose a signal monitoring system using NI myRIO connected with the wireless body sensor network through multi-channel signal acquisition method. Based on the server side validation of the signal, the data connected to the local server is updated in the cloud. The Internet of Things (IoT) architecture is used to get the mobility and fast access of patient data to healthcare service providers. This research work proposes a novel architecture for wireless physiological signal monitoring system using ubiquitous healthcare services by virtual Internet of Things. We showed an improvement in method of access and real time dynamic monitoring of physiological signal of this remote monitoring system using virtual Internet of thing approach. This remote monitoring and access system is evaluated in conventional value. This proposed system is envisioned to modern smart health care system by high utility and user friendly in clinical applications. We claim that the proposed scheme significantly improves the accuracy of the remote monitoring system compared to the other wireless communication methods in clinical system.

Utilisation of general practitioner services by socio-economic disadvantage and geographic remoteness.

To examine the association between socio-economic status (SES) and GP utilisation across Statistical Local Areas (SLAs) that differed in their geographic remoteness, and to assess whether Indigenous status and GP availability modified the association. Retrospective analysis of Medicare data for all unreferred GP consultations (1996/97) for 952 SLAs comprising the six Australian States. Geographic remoteness was ascertained using the Area Remoteness Index of Australia (ARIA), and SES was measured by grouping SLAs into tertiles based on their Index of Relative Socioeconomic Disadvantage score. Age/sex standardised rates of GP utilisation for each SLA. In SLAs classified as 'highly accessible', rates of GP use were 10.8% higher (95% CI 5.7-16.0) in the most socio-economically disadvantaged tertile after adjustment for Indigenous status and GP availability. A very different pattern of GP utilsation was found in 'remote/very remote' SLAs. After adjustment, rates of GP use in the most socio-economically disadvantaged tertile were 25.3% lower (95% CI 5.9-40.7) than in the most advantaged tertile. People in socio-economically disadvantaged metropolitan SLAs have higher rates of GP utilisation, as would be expected due to their poorer health. This is not true for people living in disadvantaged remote/very remote SLAs: in these areas, those most in need of GP services are least likely to receive them. Australia may lay claim to having a primary health care system that provides universal coverage, but we are still some way from having a system that is economically and geographically accessible to all.

Incorporating Brokers within Collaboration Environments

NASA Astrophysics Data System (ADS)

Rajasekar, A.; Moore, R.; de Torcy, A.

2013-12-01

A collaboration environment, such as the integrated Rule Oriented Data System (iRODS - http://irods.diceresearch.org), provides interoperability mechanisms for accessing storage systems, authentication systems, messaging systems, information catalogs, networks, and policy engines from a wide variety of clients. The interoperability mechanisms function as brokers, translating actions requested by clients to the protocol required by a specific technology. The iRODS data grid is used to enable collaborative research within hydrology, seismology, earth science, climate, oceanography, plant biology, astronomy, physics, and genomics disciplines. Although each domain has unique resources, data formats, semantics, and protocols, the iRODS system provides a generic framework that is capable of managing collaborative research initiatives that span multiple disciplines. Each interoperability mechanism (broker) is linked to a name space that enables unified access across the heterogeneous systems. The collaboration environment provides not only support for brokers, but also support for virtualization of name spaces for users, files, collections, storage systems, metadata, and policies. The broker enables access to data or information in a remote system using the appropriate protocol, while the collaboration environment provides a uniform naming convention for accessing and manipulating each object. Within the NSF DataNet Federation Consortium project (http://www.datafed.org), three basic types of interoperability mechanisms have been identified and applied: 1) drivers for managing manipulation at the remote resource (such as data subsetting), 2) micro-services that execute the protocol required by the remote resource, and 3) policies for controlling the execution. For example, drivers have been written for manipulating NetCDF and HDF formatted files within THREDDS servers. Micro-services have been written that manage interactions with the CUAHSI data repository, the DataONE information catalog, and the GeoBrain broker. Policies have been written that manage transfer of messages between an iRODS message queue and the Advanced Message Queuing Protocol. Examples of these brokering mechanisms will be presented. The DFC collaboration environment serves as the intermediary between community resources and compute grids, enabling reproducible data-driven research. It is possible to create an analysis workflow that retrieves data subsets from a remote server, assemble the required input files, automate the execution of the workflow, automatically track the provenance of the workflow, and share the input files, workflow, and output files. A collaborator can re-execute a shared workflow, compare results, change input files, and re-execute an analysis.

Context-aware access control for pervasive access to process-based healthcare systems.

PubMed

Koufi, Vassiliki; Vassilacopoulos, George

2008-01-01

Healthcare is an increasingly collaborative enterprise involving a broad range of healthcare services provided by many individuals and organizations. Grid technology has been widely recognized as a means for integrating disparate computing resources in the healthcare field. Moreover, Grid portal applications can be developed on a wireless and mobile infrastructure to execute healthcare processes which, in turn, can provide remote access to Grid database services. Such an environment provides ubiquitous and pervasive access to integrated healthcare services at the point of care, thus improving healthcare quality. In such environments, the ability to provide an effective access control mechanism that meets the requirement of the least privilege principle is essential. Adherence to the least privilege principle requires continuous adjustments of user permissions in order to adapt to the current situation. This paper presents a context-aware access control mechanism for HDGPortal, a Grid portal application which provides access to workflow-based healthcare processes using wireless Personal Digital Assistants. The proposed mechanism builds upon and enhances security mechanisms provided by the Grid Security Infrastructure. It provides tight, just-in-time permissions so that authorized users get access to specific objects according to the current context. These permissions are subject to continuous adjustments triggered by the changing context. Thus, the risk of compromising information integrity during task executions is reduced.

Young people with psychological or psychiatric problems are managed largely by primary care practitioners, many of whom feel inadequately trained, ill equipped, and uncomfortable with this responsibility. Accessing specialist pediatric and psychological services, often located in and near large urban centers, is a particular challenge for rural and remote communities. Live interactive videoconferencing technology (telepsychiatry) presents innovative opportunities to bridge these service gaps. The TeleLink Mental Health Program at The Hospital for Sick Children in Toronto offers a comprehensive, collaborative model of enhancing local community systems of care in rural and remote Ontario using videoconferencing. With a focus on clinical consultation, collaborative care, education and training, evaluation, and research, ready access to pediatric psychiatrists and other specialist mental health service providers can effectively extend the boundaries of the medical home. Medical trainees in urban teaching centers are also expanding their knowledge of and comfort level with rural mental health issues, various complementary service models, and the potentials of videoconferencing in providing psychiatric and psychological services. Committed and enthusiastic champions, a positive attitude, creativity, and flexibility are a few of the necessary attributes ensuring viability and integration of telemental health programs.

2001-01-01

This report summarizes development of the ADTT web-based design environment by the ELORET team in 2000. The Advanced Design Technology Testbed had been in development for several years, with demonstration applications restricted to aerodynamic analyses of subsonic aircraft. The key changes achieved this year were improvements in Web-based accessibility, evaluation of collaborative visualization, remote invocation of geometry updates and performance analysis, and application to aerospace system analysis. Significant effort was also devoted to post-processing of data, chiefly through comparison of similar data for alternative vehicle concepts. Such comparison is an essential requirement for designers to make informed choices between alternatives. The next section of this report provides more discussion of the goals for ADTT development. Section 3 provides screen shots from a sample session in the ADTT environment, including Login and navigation to the project of interest, data inspection, analysis execution and output evaluation. The following section provides discussion of implementation details and recommendations for future development of the software and information technologies that provide the key functionality of the ADTT system. Section 5 discusses the integration architecture for the system, which links machines running different operating systems and provides unified access to data stored in distributed locations. Security is a significant issue for this system, especially for remote access to NAS machines, so Section 6 discusses several architectural considerations with respect to security. Additional details of some aspects of ADTT development are included in Appendices.

Remotely Delivered Exercise-Based Cardiac Rehabilitation: Design and Content Development of a Novel mHealth Platform

PubMed Central

Gant, Nicholas; Meads, Andrew; Warren, Ian; Maddison, Ralph

2016-01-01

Background Participation in traditional center-based cardiac rehabilitation exercise programs (exCR) is limited by accessibility barriers. Mobile health (mHealth) technologies can overcome these barriers while preserving critical attributes of center-based exCR monitoring and coaching, but these opportunities have not yet been capitalized on. Objective We aimed to design and develop an evidence- and theory-based mHealth platform for remote delivery of exCR to any geographical location. Methods An iterative process was used to design and develop an evidence- and theory-based mHealth platform (REMOTE-CR) that provides real-time remote exercise monitoring and coaching, behavior change education, and social support. Results The REMOTE-CR platform comprises a commercially available smartphone and wearable sensor, custom smartphone and Web-based applications (apps), and a custom middleware. The platform allows exCR specialists to monitor patients’ exercise and provide individualized coaching in real-time, from almost any location, and provide behavior change education and social support. Intervention content incorporates Social Cognitive Theory, Self-determination Theory, and a taxonomy of behavior change techniques. Exercise components are based on guidelines for clinical exercise prescription. Conclusions The REMOTE-CR platform extends the capabilities of previous telehealth exCR platforms and narrows the gap between existing center- and home-based exCR services. REMOTE-CR can complement center-based exCR by providing an alternative option for patients whose needs are not being met. Remotely monitored exCR may be more cost-effective than establishing additional center-based programs. The effectiveness and acceptability of REMOTE-CR are now being evaluated in a noninferiority randomized controlled trial. PMID:27342791

Remote Monitoring of Cardiac Implantable Electronic Devices.

Cheung, Christopher C; Deyell, Marc W

Over the past decade, technological advancements have transformed the delivery of care for arrhythmia patients. From early transtelephonic monitoring to new devices capable of wireless and cellular transmission, remote monitoring has revolutionized device care. In this article, we review the current evolution and evidence for remote monitoring in patients with cardiac implantable electronic devices. From passive transmission of device diagnostics, to active transmission of patient- and device-triggered alerts, remote monitoring can shorten the time to diagnosis and treatment. Studies have shown that remote monitoring can reduce hospitalization and emergency room visits, and improve survival. Remote monitoring can also reduce the health care costs, while providing increased access to patients living in rural or marginalized communities. Unfortunately, as many as two-thirds of patients with remote monitoring-capable devices do not use, or are not offered, this feature. Current guidelines recommend remote monitoring and interrogation, combined with annual in-person evaluation in all cardiac device patients. Remote monitoring should be considered in all eligible device patients and should be considered standard of care. Copyright © 2018 Canadian Cardiovascular Society. Published by Elsevier Inc.

Background: Remote-access techniques have been described over the recent years as a method of removing the thyroid gland without an incision in the neck. However, there is confusion related to the number of techniques available and the ideal patient selection criteria for a given technique. The aims of this review were to develop a simple classification of these approaches, describe the optimal patient selection criteria, evaluate the outcomes objectively, and define the barriers to adoption. Methods: A review of the literature was performed to identify the described techniques. A simple classification was developed. Technical details, outcomes, and the learning curve were described. Expert opinion consensus was formulated regarding recommendations for patient selection and performance of remote-access thyroid surgery. Results: Remote-access thyroid procedures can be categorized into endoscopic or robotic breast, bilateral axillo-breast, axillary, and facelift approaches. The experience in the United States involves the latter two techniques. The limited data in the literature suggest long operative times, a steep learning curve, and higher costs with remote-access thyroid surgery compared with conventional thyroidectomy. Nevertheless, a consensus was reached that, in appropriate hands, it can be a viable option for patients with unilateral small nodules who wish to avoid a neck incision. Conclusions: Remote-access thyroidectomy has a role in a small group of patients who fit strict selection criteria. These approaches require an additional level of expertise, and therefore should be done by surgeons performing a high volume of thyroid and robotic surgery. PMID:26858014

2004-01-01

This paper describes an experiment to prototype a new way of conducting science by applying networking and distributed computing technologies to an Earth Science application. A combination of satellite, wireless, and terrestrial networking provided geologists at a remote field site with interactive access to supercomputer facilities at two NASA centers, thus enabling them to validate and calibrate remotely sensed geological data in near-real time. This represents a fundamental shift in the way that Earth scientists analyze remotely sensed data. In this paper we describe the experiment and the network infrastructure that enabled it, analyze the data flow during the experiment, and discuss the scientific impact of the results.

Remote sensing technology is advancing at an unprecedented rate. At the forefront of the new technological developments are unmanned aircraft systems (UAS). The advent of small, lightweight, low-cost, and user-friendly UAS is greatly expanding the potential applications of remote sensing technology and improving the set of tools available to researchers seeking to map and monitor terrain from above. In this article, we explore the applications of a small UAS for mapping informal diamond mining sites in Africa. We found that this technology provides aerial imagery of unparalleled resolution in a data-sparse, difficult to access, and remote terrain.

Enabling Remote Activity: Using mobile technology for remote participation in geoscience fieldwork

NASA Astrophysics Data System (ADS)

Davies, Sarah; Collins, Trevor; Gaved, Mark; Bartlett, Jessica; Valentine, Chris; McCann, Lewis

2010-05-01

Field-based activities are regarded as essential to the development of a range of professional and personal skills within the geosciences. Students enjoy field activities, preferring these to learning with simulations (Spicer and Stratford 2001), and these improve deeper learning and understanding (Kern and Carpenter, 1984; Elkins and Elkins, 2007). However, some students find it difficult to access these field-based learning opportunities. Field sites may be remote and often require travel across uneven, challenging or potentially dangerous terrain. Mobility-impaired students are particularly limited in their opportunities to participate in field-based learning activities and, as higher education institutions have a responsibility to provide inclusive opportunities for students (UK Disability Discrimination Act 1995, UK Special Education Needs and Disability Rights Act 2001), the need for inclusive fieldwork learning is being increasingly recognised. The Enabling Remote Activity (ERA) project has been investigating how mobile communications technologies might allow field learning experiences to be brought to students who would otherwise find it difficult to participate, and also to enhance activities for all participants. It uses a rapidly deployable, battery-powered wireless network to transmit video, audio, and high resolution still images to connect participants at an accessible location with participants in the field. Crucially, the system uses a transient wireless network, allowing multiple locations to be explored during a field visit, and for plans to be changed dynamically if required. Central to the concept is the requirement for independent investigative learning: students are enabled to participate actively in the learning experience and to direct the investigations, as opposed to being simply remote viewers of the experience. Two ways of using the ERA system have been investigated: remote access and collaborative groupwork. In 2006 and 2008 remote access was used to enable mobility-impaired students to take part in and complete a field course. This involved connecting the student in an accessible vehicle located close to the field site, via a wireless network, to a geologist in the field. The geologist worked alongside the general body of students and the field tutor as each geological site was investigated. Two-way communications allowed the student to guide the geologist to provide video panoramas of the area, to select areas of interest for further study and to obtain high resolution images of specific points. The students were able to work through the field activities alongside the rest of the student group. A collaborative groupwork trial (2007) was used to connect two groups of students; one in an accessible laboratory, the other at a field site. Traditionally, students collect data in the field and analyze it on return to the laboratory; this system proposes a more rapid collection and analysis procedure, with information being transmitted between sites with field and laboratory participants having their own distinct, significant roles within the learning activity. This project recently received an award at the 2008 Handheld Learning Conference and a HEFCE sponsored Open University Teaching Award. In contrast to the use of ‘virtual fieldwork' that aims to provide simulations or a resource for a student to use, the focus of this project is on how technology can be used to support actual fieldwork activities. This approach has been trialled now over three field seasons, with students using the system to remotely participate in fieldwork activities. Interviews with tutors and students have shown that this was perceived as valuable and allowed participants to achieve the learning objectives of the course alongside their peers. The challenges of remote fieldwork concern the co-ordination of students' activities, the integration of remote and field activities and practical issues of lightweight, easy-to-use, robust technologies and the provision of a reliable communications network.

O'Sullivan, Belinda G; Joyce, Catherine M; McGrail, Matthew R

2014-09-04

Outreach has been endorsed as an important global strategy to promote universal access to health care but it depends on health workers who are willing to travel. In Australia, rural outreach is commonly provided by specialist doctors who periodically visit the same community over time. However information about the level of participation and the distribution of these services nationally is limited. This paper outlines the proportion of Australian specialist doctors who participate in rural outreach, describes their characteristics and assesses how these characteristics influence remote outreach provision. We used data from the Medicine in Australia: Balancing Employment and Life (MABEL) survey, collected between June and November 2008. Weighted logistic regression analyses examined the effect of covariates: sex, age, specialist residential location, rural background, practice arrangements and specialist group on rural outreach. A separate logistic regression analysis studied the effect of covariates on remote outreach compared with other rural outreach. Of 4,596 specialist doctors, 19% (n = 909) provided outreach; of which, 16% (n = 149) provided remote outreach. Most (75%) outreach providers were metropolitan specialists. In multivariate analysis, outreach was associated with being male (OR 1.38, 1.12 to 1.69), having a rural residence (both inner regional: OR 2.07, 1.68 to 2.54; and outer regional/remote: OR 3.40, 2.38 to 4.87) and working in private consulting rooms (OR 1.24, 1.01 to 1.53). Remote outreach was associated with increasing 5-year age (OR1.17, 1.05 to 1.31) and residing in an outer regional/remote location (OR 10.84, 5.82 to 20.19). Specialists based in inner regional areas were less likely than metropolitan-based specialists to provide remote outreach (OR 0.35, 0.17 to 0.70). There is a healthy level of interest in rural outreach work, but remote outreach is less common. Whilst most providers are metropolitan-based, rural doctors are more likely to provide outreach services. Remote distribution is influenced differently: inner regional specialists are less likely to provide remote services compared with metropolitan specialists. To benefit from outreach services and ensure adequate remote distribution, we need to promote coordinated delivery of services arising from metropolitan and rural locations according to rural and remote health need.

To inform about a very unique and first of its kind telehealth pilot study in India that has provided virtual telehealth consultation to eye care patients in low resource at remote villages. Provision of Access to eye care services in remote population is always challenging due to pragmatic reasons. Advances in Telehealth technologies have provided an opportunity to improve access to remote population. However, current Telehealth technologies are limited to face-to-face video consultation only. We inform about a pilot study that illustrates real-time imaging access to ophthalmologists. Our innovative software led technology solution allowed screening of patients with varying ocular conditions. Eye camps were conducted in 2 districts in South India over a 12-month period in 2014. Total of 196 eye camps were conducted. Total of 19,634 patients attended the eye camps. Innovative software was used to conduct consultation with the ophthalmologist located in the city hospital. The software enabled virtual visit and allowed instant sharing of fundus camera images for assessment and diagnosis. About 71% of the patients were found to have Refractive Error problems, 15% of them were found to have cataract, 7% of the patients were diagnosed to have Retina problems and 7% of the patients were found to have other ocular diseases. The patients requiring cataract surgery were immediately transferred to city hospital for treatment. Software led assessment of fundus camera images assisted in identifying retinal eye diseases. Our real-time virtual visit software assisted in specialist care provision and illustrated a novel tele health solution for low resource population.

DIDBase: Intelligent, Interactive Archiving Technology for Ionogram Data

Vertical ionospheric sounding data have been used in a variety of scenarios for ionospheric now-casting. Growing need for an accurate real-time specification of vertical electron density distribution at multiple locations stimulates interest to intelligent data management systems that can arrange concurrent, remote access to the acquired data. This type of data access requires high level of interaction and organization to support routing of data between ionosondes, data analysts, quality validation experts, end user applications, data managers, and online data repositories such as the World Data Centers. Digital Ionogram Database (DIDBase) is a pilot project started at UMASS Lowell in 2001, sponsored in part by the Air Force Research Laboratory, for management of real-time and retro data from a network of 50 digisondes. The DIDBase archives hold both raw and derived digisonde data under management of a commerical strength DBMS, providing convenient means for automated ingestion of real-time data from online digisondes (40 locations worldwide as of September 2004), remote read access to the data over HTTP Web protocol (http://ulcar.uml.edu/DIDBase/), remote read/write access from SAO Explorer workstations used for data visualization and interactive editing, and an ADRES subsystem for automated management of data requests. DIDBase and ADRES employ cross-platform solutions for all involved software, exchange protocols, and data. The paper briefly describes the DIDBase operations during a recent Cal/Val campaign for the SSUSI/SSULI instruments on the DMSP F16 spacecraft. Here 26 online digisondes provided ground-truth NmF2 data for the overhead and limb passes of the spacecraft. Since the start of the campaign in December 2003, the total number of the ADRES requests exceeded 9,000 by summer 2004.

2006-12-01

Using NASA satellite remote sensing data from multiple sources for hydrologic applications can be a daunting task and requires a detailed understanding of the data's internal structure and physical implementation. Gaining this understanding and applying it to data reduction is a time-consuming task that must be undertaken before the core investigation can begin. In order to facilitate such investigations, the NASA Goddard Earth Sciences Data and Information Services Center (GES DISC) has developed the GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure or "Giovanni," which supports a family of Web interfaces (instances) that allow users to perform interactive visualization and analysis online without downloading any data. Two such Giovanni instances are particularly relevant to hydrologic applications: the Tropical Rainfall Measuring Mission (TRMM) Online Visualization and Analysis System (TOVAS) and the Agricultural Online Visualization and Analysis System (AOVAS), both highly popular and widely used for a variety of applications, including those related to several NASA Applications of National Priority, such as Agricultural Efficiency, Disaster Management, Ecological Forecasting, Homeland Security, and Public Health. Dynamic, context- sensitive Web services provided by TOVAS and AOVAS enable users to seamlessly access NASA data from within, and deeply integrate the data into, their local client environments. One example is between TOVAS and Florida International University's TerraFly, a Web-enabled system that serves a broad segment of the research and applications community, by facilitating access to various textual, remotely sensed, and vector data. Another example is between AOVAS and the U.S. Department of Agriculture Foreign Agricultural Service (USDA FAS)'s Crop Explorer, the primary decision support tool used by FAS to monitor the production, supply, and demand of agricultural commodities worldwide. AOVAS is also part of GES DISC's Agricultural Information System (AIS), which can operationally provide satellite remote sensing data products (e.g., near- real-time rainfall) and analysis services to agricultural users. AIS enables the remote, interoperable access to distributed data, by using the GrADS-Data Server (GDS) and the Open Geospatial Consortium (OGC)- compliant MapServer. The latter allows the access of AIS data from any OGC-compliant client, such as the Earth-Sun System Gateway (ESG) or Google Earth. The Giovanni system is evolving towards a Service- Oriented Architecture and is highly customizable (e.g., adding new products or services), thus availing the hydrologic applications user community of Giovanni's simple-to-use and powerful capabilities to improve decision-making.

Significant effort has been expended to provide infrastructure and to facilitate the remote collaborations within the fusion community and out. Through the Office of Fusion Energy Science Information Technology Initiative, communication technologies utilized by the fusion community are being improved. The initial thrust of the initiative has been collaborative seminars and meetings. Under the initiative 23 sites, both laboratory and university, were provided with hardware required to remotely view, or project, documents being presented. The hardware is capable of delivering documents to a web browser, or to compatible hardware, over ESNET in an access controlled manner. The ability also exists for documents to originate from virtually any of the collaborating sites. In addition, RealNetwork servers are being tested to provide audio and/or video, in a non-interactive environment with MBONE providing two-way interaction where needed. Additional effort is directed at remote distributed computing, file systems, security, and standard data storage and retrieval methods. This work supported by DoE contract No. W-7405-ENG-48

Rosset, Antoine; Heuberger, Joris; Pysher, Lance; Ratib, Osman

2006-03-01

We have elected to explore peer-to-peer technology as an alternative to centralized PACS architecture for the increasing requirements for wide access to images inside and outside a radiology department. The goal being to allow users across the enterprise to access any study anytime without the need for prefetching or routing of images from central archive. Images can be accessed between different workstations and local storage nodes. We implemented "bonjour" a new remote file access technology developed by Apple allowing applications to share data and files remotely with optimized data access and data transfer. Our Open-source image display platform called OsiriX was adapted to allow sharing of local DICOM images through direct access of each local SQL database to be accessible from any other OsiriX workstation over the network. A server version of Osirix Core Data database also allows to access distributed archives servers in the same way. The infrastructure implemented allows fast and efficient access to any image anywhere anytime independently from the actual physical location of the data. It also allows benefiting from the performance of distributed low-cost and high capacity storage servers that can provide efficient caching of PACS data that was found to be 10 to 20 x faster that accessing the same date from the central PACS archive. It is particularly suitable for large hospitals and academic environments where clinical conferences, interdisciplinary discussions and successive sessions of image processing are often part of complex workflow or patient management and decision making.

CT: Theintegration of remote sensing tools and technology with the spatial analysis orientation of geographic information systems is a complex task. In this paper, we focus on the issues of making data available and useful to the user. In part, this involves a set of problems which reflect on the physical and logical structures used to encode the data. At the same time, however, the mechanisms and protocols which provide information about the data, and which maintain the data through time, have become increasingly important. We discuss these latter issues from the viewpoint of the functions which must be provided by archives of spatial data.

The use of electronic health records is rapidly increasing. However, the integration of this technology into the education of health professionals and health informaticians has largely remained to be explored. In this paper we describe an approach to providing remote access to electronic health records for use in health professional and health informatics education at the undergraduate and graduate levels. The University of Victoria EHR Educational Portal was designed by the authors to allow for remote Web-based access by students to a range of systems hosted on the portal. Architectural considerations and the evolution of the portal structure from prototype to production system are described. The paper also describes our initial applications of the approach in integrating EHRs into nursing, medical and health informatics educational programs. PMID:20351822

To identify mechanisms for the successful implementation of support strategies for health-care practitioners in rural and remote contexts. This is an integrative review and thematic synthesis of the empirical literature that examines support interventions for health-care practitioners in rural and remote contexts. This review includes 43 papers that evaluated support strategies for the rural and remote health workforce. Interventions were predominantly training and education programmes with limited evaluations of supervision and mentoring interventions. The mechanisms associated with successful outcomes included: access to appropriate and adequate training, skills and knowledge for the support intervention; accessible and adequate resources; active involvement of stakeholders in programme design, implementation and evaluation; a needs analysis prior to the intervention; external support, organisation, facilitation and/or coordination of the programme; marketing of the programme; organisational commitment; appropriate mode of delivery; leadership; and regular feedback and evaluation of the programme. Through a synthesis of the literature, this research has identified a number of mechanisms that are associated with successful support interventions for health-care practitioners in rural and remote contexts. This research utilised a methodology developed for studying complex interventions in response to the perceived limitations of traditional systematic reviews. This synthesis of the evidence will provide decision-makers at all levels with a collection of mechanisms that can assist the development and implementation of support strategies for staff in rural and remote contexts.

Environmental assessments and subsequent modifications conducted by healthcare professionals can enhance home safety and promote independent living. However, travel time, expense and the availability of qualified professionals can limit the broad application of this intervention. Remote technology has the potential to increase access to home safety evaluations. This study describes the development and validation of a remote home safety protocol that can be used by a caregiver of an elderly person to video-record their home environment for later viewing and evaluation by a trained professional. The protocol was developed based on literature reviews and evaluations from clinical and content experts. Cognitive interviews were conducted with a group of six caregivers to validate the protocol. The final protocol included step-by-step directions to record indoor and outdoor areas of the home. The validation process resulted in modifications related to safety, clarity of the protocol, readability, visual appearance, technical descriptions and usability. Our final protocol includes detailed instructions that a caregiver should be able to follow to record a home environment for subsequent evaluation by a home safety professional. Implications for Rehabilitation The results of this study have several implications for rehabilitation practice The remote home safety evaluation protocol can potentially improve access to rehabilitation services for clients in remote areas and prevent unnecessary delays for needed care. Using our protocol, a patient's caregiver can partner with therapists to quickly and efficiently evaluate a patient's home before they are released from the hospital. Caregiver narration, which reflects a caregiver's own perspective, is critical to evaluating home safety. In-home safety evaluations, currently not available to all who need them due to access barriers, can enhance a patient's independence and provide a safer home environment.

Background Health anxiety and medically unexplained symptoms cost the National Health Service (NHS) an estimated £3 billion per year in unnecessary costs with little evidence of patient benefit. Effective treatment is rarely taken up due to issues such as stigma or previous negative experiences with mental health services. An approach to overcome this might be to offer remotely delivered psychological therapy, which can be just as effective as face-to-face therapy and may be more accessible and suitable. Aims To investigate the clinical outcomes and cost-effectiveness of remotely delivered cognitive–behavioural therapy (CBT) to people with high health anxiety repeatedly accessing unscheduled care (trial registration: NCT02298036). Method A multicentre randomised controlled trial (RCT) will be undertaken in primary and secondary care providers of unscheduled care across the East Midlands. One hundred and forty-four eligible participants will be equally randomised to receive either remote CBT (6–12 sessions) or treatment as usual (TAU). Two doctoral research studies will investigate the barriers and facilitators to delivering the intervention and the factors contributing to the optimisation of therapeutic outcome. Results This trial will be the first to test the clinical outcomes and cost-effectiveness of remotely delivered CBT for the treatment of high health anxiety. Conclusions The findings will enable an understanding as to how this intervention might fit into a wider care pathway to enhance patient experience of care. Declaration of interest None.

Quantifying Changes in Accessible Water in the Colorado River Basin

NASA Astrophysics Data System (ADS)

Castle, S.; Thomas, B.; Reager, J. T.; Swenson, S. C.; Famiglietti, J. S.

2013-12-01

The Colorado River Basin (CRB) in the western United States is heavily managed yet remains one of the most over-allocated rivers in the world providing water across seven US states and Mexico. Future water management strategies in the CRB have employed land surface models to forecast discharges; such approaches have focused on discharge estimates to meet allocation requirements yet ignore groundwater abstractions to meet water demands. In this analysis, we illustrate the impact of changes in accessible water, which we define as the conjunctive use of both surface water reservoir storage and groundwater storage, using remote sensing observations to explore sustainable water management strategies in the CRB. We employ high resolution Landsat Thematic Mapper satellite data to detect changes in reservoir storage in the two largest reservoirs within the CRB, Lakes Mead and Powell, and the Gravity Recovery and Climate Experiment (GRACE) terrestrial water storage anomalies to isolate changes in basin-wide groundwater storage in the Upper and Lower CRB from October 2003 to December 2012. Our approach quantifies reservoir and groundwater storage within the CRB using remote sensing to provide new information to water managers to sustainably and conjunctively manage accessible water.

With regards to end-of-life care, there is scant published research that looks specifically at the provision of palliative care services for Indigenous people. In addition, for Indigenous people in the rural and remote areas there is only limited literature that focuses on the problems associated with geography. To address the hiatus in the literature on Aboriginal, rural and remote palliative care, the following article provides findings from a two-year research project, funded by Australia's National Health and Medical Research Council (NH&MRC), which developed an innovative model for Indigenous palliative care. The data was collected through a qualitative methodology (descriptive phenomenology) which involved open-ended in-depth interviews, audio-recorded, transcribed verbatim and thematically analysed. The sub-set of findings from the study presented in this paper examine issues in relation to the many practical obstacles in relation to palliative care service provision to Indigenous people in the rural and remote areas. The findings are a testament to the ingenuity and dedication of those who provide end-of-life care for Aboriginal peoples in rural and remote locations. The information about the many obstacles associated with equipment, power, transport, distance and telephone access provide important insights to inform the development of health policy planning and funding. The topic is specifically relevant to nurses as further findings from the study indicate that clinic and community nurses are key health professionals providing care to Indigenous people in the rural and remote areas.

We have prepared remote observing environment for the 188 cm telescope at Okayama Astrophysical Observatory. A KVM-over-IP and a VPN gateway are employed as core devices, which offer reliable, secure and fast link between on site and remote sites. We have confirmed the KVM-over-IP has ideal characteristics for serving the remote observing environment; the use is simple for both users and maintainer; access from any platform is available; multiple and simultaneous access is possible; and maintenance load is small. We also demonstrated that the degradation of observing efficiency specific to the remote observing is negligibly small. The remote observing environment has fully opened since the semester 2016A, about 30% of the total observing time in the last semester was occupied by remote observing.

This research is focused on methodological challenges and considerations associated with the estimation of the geographical aspects of access to healthcare with a focus on rural and remote areas. With the assumption that GIS-based accessibility measures for rural healthcare services will vary across geographic units of analysis and estimation techniques, which could influence the interpretation of spatial access to rural healthcare services. Estimations of geographical accessibility depend on variations of the following three parameters: 1) quality of input data; 2) accessibility method; and 3) geographical area. This research investigated the spatial distributions of physiotherapists (PTs) in comparison to family physicians (FPs) across Saskatchewan, Canada. The three-steps floating catchment areas (3SFCA) method was applied to calculate the accessibility scores for both PT and FP services at two different geographical units. A comparison of accessibility scores to simple healthcare provider-to-population ratios was also calculated. The results vary considerably depending on the accessibility methods used and the choice of geographical area unit for measuring geographical accessibility for both FP and PT services. These findings raise intriguing questions regarding the nature and extent of technical issues and methodological considerations that can affect GIS-based measures in health services research and planning. This study demonstrates how the selection of geographical areal units and different methods for measuring geographical accessibility could affect the distribution of healthcare resources in rural areas. These methodological issues have implications for determining where there is reduced access that will ultimately impact health human resource priorities and policies. Copyright © 2017 Elsevier Ltd.

The unprecedented torrent of data returned by the Solar Dynamics Observatory is both a blessing and a barrier: a blessing for making available data with significantly higher spatial and temporal resolution, but a barrier for scientists to access, browse and analyze them. With such staggering data volume, the data is bound to be accessible only from a few repositories and users will have to deal with data sets effectively immobile and practically difficult to download. From a scientist's perspective this poses three challenges: accessing, browsing and finding interesting data while avoiding the proverbial search for a needle in a haystack. To address these challenges, we have developed JHelioviewer, an open-source visualization software that lets users browse large data volumes both as still images and movies. We did so by deploying an efficient image encoding, storage, and dissemination solution using the JPEG 2000 standard. This solution enables users to access remote images at different resolution levels as a single data stream. Users can view, manipulate, pan, zoom, and overlay JPEG 2000 compressed data quickly, without severe network bandwidth penalties. Besides viewing data, the browser provides third-party metadata and event catalog integration to quickly locate data of interest, as well as an interface to the Virtual Solar Observatory to download science-quality data. As part of the Helioviewer Project, JHelioviewer offers intuitive ways to browse large amounts of heterogeneous data remotely and provides an extensible and customizable open-source platform for the scientific community.

Safe Grid

Chow, Edward T.; Stewart, Helen; Korsmeyer, David (Technical Monitor)

2003-01-01

The biggest users of GRID technologies came from the science and technology communities. These consist of government, industry and academia (national and international). The NASA GRID is moving into a higher technology readiness level (TRL) today; and as a joint effort among these leaders within government, academia, and industry, the NASA GRID plans to extend availability to enable scientists and engineers across these geographical boundaries collaborate to solve important problems facing the world in the 21 st century. In order to enable NASA programs and missions to use IPG resources for program and mission design, the IPG capabilities needs to be accessible from inside the NASA center networks. However, because different NASA centers maintain different security domains, the GRID penetration across different firewalls is a concern for center security people. This is the reason why some IPG resources are been separated from the NASA center network. Also, because of the center network security and ITAR concerns, the NASA IPG resource owner may not have full control over who can access remotely from outside the NASA center. In order to obtain organizational approval for secured remote access, the IPG infrastructure needs to be adapted to work with the NASA business process. Improvements need to be made before the IPG can be used for NASA program and mission development. The Secured Advanced Federated Environment (SAFE) technology is designed to provide federated security across NASA center and NASA partner's security domains. Instead of one giant center firewall which can be difficult to modify for different GRID applications, the SAFE "micro security domain" provide large number of professionally managed "micro firewalls" that can allow NASA centers to accept remote IPG access without the worry of damaging other center resources. The SAFE policy-driven capability-based federated security mechanism can enable joint organizational and resource owner approved remote access from outside of NASA centers. A SAFE enabled IPG can enable IPG capabilities to be available to NASA mission design teams across different NASA center and partner company firewalls. This paper will first discuss some of the potential security issues for IPG to work across NASA center firewalls. We will then present the SAFE federated security model. Finally we will present the concept of the architecture of a SAFE enabled IPG and how it can benefit NASA mission development.

Non-dental primary care providers’ views on challenges in providing oral health services and strategies to improve oral health in Australian rural and remote communities: a qualitative study

Objectives To investigate the challenges of providing oral health advice/treatment as experienced by non-dental primary care providers in rural and remote areas with no resident dentist, and their views on ways in which oral health and oral health services could be improved for their communities. Design Qualitative study with semistructured interviews and thematic analysis. Setting Four remote communities in outback Queensland, Australia. Participants 35 primary care providers who had experience in providing oral health advice to patients and four dental care providers who had provided oral health services to patients from the four communities. Results In the absence of a resident dentist, rural and remote residents did present to non-dental primary care providers with oral health problems such as toothache, abscess, oral/gum infection and sore mouth for treatment and advice. Themes emerged from the interview data around communication challenges and strategies to improve oral health. Although, non-dental care providers commonly advised patients to see a dentist, they rarely communicated with the dentist in the nearest regional town. Participants proposed that oral health could be improved by: enabling access to dental practitioners, educating communities on preventive oral healthcare, and building the skills and knowledge base of non-dental primary care providers in the field of oral health. Conclusions Prevention is a cornerstone to better oral health in rural and remote communities as well as in more urbanised communities. Strategies to improve the provision of dental services by either visiting or resident dental practitioners should include scope to provide community-based oral health promotion activities, and to engage more closely with other primary care service providers in these small communities.

The Little Thompson Observatory is believed to be the first observatory built as part of a high school and accessible to other schools remotely, via the Internet. This observatory is the second member of the Telescopes in Education (TIE) project. Construction of the building and dome has been completed, and first light is planned for spring 1999. The observatory is located on the grounds of Berthoud High School in northern Colorado. Local schools and youth organizations will have prioritized access to the telescope, and there will also be opportunities for public viewing. After midnight, the telescope will be open to world-wide use by schools via the Internet following the model of the first TIE observatory, the 24" telescope on Mt. Wilson. Students remotely connect to the observatory over the Internet, and then receive the images on their local computers. The observatory grew out of grassroots support from the local community surrounding Berthoud, Colorado, a town of 3,500 residents. TIE has provided the observatory with a Tinsley 18" Cassegrain telescope on a 10-year loan. The facility has been built with tremendous support from volunteers and the local school district. We have received an IDEAS grant to provide teacher training workshops which will allow K-12 schools in northern Colorado to make use of the Little Thompson Observatory, including remote observing from classrooms.

Algorithms and Libraries

1998-01-01

This exploratory study initiated our inquiry into algorithms and applications that would benefit by latency tolerant approach to algorithm building, including the construction of new algorithms where appropriate. In a multithreaded execution, when a processor reaches a point where remote memory access is necessary, the request is sent out on the network and a context--switch occurs to a new thread of computation. This effectively masks a long and unpredictable latency due to remote loads, thereby providing tolerance to remote access latency. We began to develop standards to profile various algorithm and application parameters, such as the degree of parallelism, granularity, precision, instruction set mix, interprocessor communication, latency etc. These tools will continue to develop and evolve as the Information Power Grid environment matures. To provide a richer context for this research, the project also focused on issues of fault-tolerance and computation migration of numerical algorithms and software. During the initial phase we tried to increase our understanding of the bottlenecks in single processor performance. Our work began by developing an approach for the automatic generation and optimization of numerical software for processors with deep memory hierarchies and pipelined functional units. Based on the results we achieved in this study we are planning to study other architectures of interest, including development of cost models, and developing code generators appropriate to these architectures.

Hawaiian volcanoes are highly accessible and well monitored by ground instruments. Nevertheless, observational gaps remain and thermal satellite imagery has proven useful in Hawai‘i for providing synoptic views of activity during intervals between field visits. Here we describe the beginning of a thermal remote sensing programme at the US Geological Survey Hawaiian Volcano Observatory (HVO). Whereas expensive receiving stations have been traditionally required to achieve rapid downloading of satellite data, we exploit free, low-latency data sources on the internet for timely access to GOES, MODIS, ASTER and EO-1 ALI imagery. Automated scripts at the observatory download these data and provide a basic display of the images. Satellite data have been extremely useful for monitoring the ongoing lava flow activity on Kīlauea's East Rift Zone at Pu‘u ‘Ō‘ō over the past few years. A recent lava flow, named Kahauale‘a 2, was upslope from residential subdivisions for over a year. Satellite data helped track the slow advance of the flow and contributed to hazard assessments. Ongoing improvement to thermal remote sensing at HVO incorporates automated hotspot detection, effusion rate estimation and lava flow forecasting, as has been done in Italy. These improvements should be useful for monitoring future activity on Mauna Loa.

The remarkable advance in sequencing technology and the rising interest in medical and environmental microbiology, biotechnology, and synthetic biology resulted in a deluge of published microbial genomes. Yet, genome annotation, comparison, and modeling remain a major bottleneck to the translation of sequence information into biological knowledge, hence computational analysis tools are continuously being developed for rapid genome annotation and interpretation. Among the earliest, most comprehensive resources for prokaryotic genome analysis, the SEED project, initiated in 2003 as an integration of genomic data and analysis tools, now contains >5,000 complete genomes, a constantly updated set of curated annotations embodied in a large and growing collection of encoded subsystems, a derived set of protein families, and hundreds of genome-scale metabolic models. Until recently, however, maintaining current copies of the SEED code and data at remote locations has been a pressing issue. To allow high-performance remote access to the SEED database, we developed the SEED Servers (http://www.theseed.org/servers): four network-based servers intended to expose the data in the underlying relational database, support basic annotation services, offer programmatic access to the capabilities of the RAST annotation server, and provide access to a growing collection of metabolic models that support flux balance analysis. The SEED servers offer open access to regularly updated data, the ability to annotate prokaryotic genomes, the ability to create metabolic reconstructions and detailed models of metabolism, and access to hundreds of existing metabolic models. This work offers and supports a framework upon which other groups can build independent research efforts. Large integrations of genomic data represent one of the major intellectual resources driving research in biology, and programmatic access to the SEED data will provide significant utility to a broad collection of potential users.

Rural populations experience several barriers to accessing clinical facilities for malaria diagnosis. Increasing penetration of ICT and mobile-phones and subsequent m-Health applications can contribute overcoming such obstacles. GIS is used to evaluate the feasibility of m-Health technologies as part of anti-malaria strategies. This study investigates where in Uganda: (1) malaria affects the largest number of people; (2) the application of m-Health protocol based on the mobile network has the highest potential impact. About 75% of the population affected by Plasmodium falciparum malaria have scarce access to healthcare facilities. The introduction of m-Health technologies should be based on the 2G protocol, as 3G mobile network coverage is still limited. The western border and the central-Southeast are the regions where m-Health could reach the largest percentage of the remote population. Six districts (Arua, Apac, Lira, Kamuli, Iganga, and Mubende) could have the largest benefit because they account for about 28% of the remote population affected by falciparum malaria with access to the 2G mobile network. The application of m-Health technologies could improve access to medical services for distant populations. Affordable remote malaria diagnosis could help to decongest health facilities, reducing costs and contagion. The combination of m-Health and GIS could provide real-time and geo-localized data transmission, improving anti-malarial strategies in Uganda. Scalability to other countries and diseases looks promising.

Lake Storage Measurements For Water Resources Management: Combining Remotely Sensed Water Levels and Surface Areas

NASA Astrophysics Data System (ADS)

Brakenridge, G. R.; Birkett, C. M.

2013-12-01

Presently operating satellite-based radar altimeters have the ability to monitor variations in surface water height for large lakes and reservoirs, and future sensors will expand observational capabilities to many smaller water bodies. Such remote sensing provides objective, independent information where in situ data are lacking or access is restricted. A USDA/NASA (http://www.pecad.fas.usda.gov/cropexplorer/global_reservoir/) program is performing operational altimetric monitoring of the largest lakes and reservoirs around the world using data from the NASA/CNES, NRL, and ESA missions. Public lake-level products from the Global Reservoir and Lake Monitor (GRLM) are a combination of archived and near real time information. The USDA/FAS utilizes the products for assessing international irrigation potential and for crop production estimates; other end-users study climate trends, observe anthropogenic effects, and/or are are involved in other water resources management and regional water security issues. At the same time, the Dartmouth Flood Observatory (http://floodobservatory.colorado.edu/), its NASA GSFC partners (http://oas.gsfc.nasa.gov/floodmap/home.html), and associated MODIS data and automated processing algorithms are providing public access to a growing GIS record of the Earth's changing surface water extent, including changes related to floods and droughts. The Observatory's web site also provide both archival and near real time information, and is based mainly on the highest spatial resolution (250 m) MODIS bands. Therefore, it is now possible to provide on an international basis reservoir and lake storage change measurements entirely from remote sensing, on a frequently updating basis. The volume change values are based on standard numerical procedures used for many decades for analysis of coeval lake area and height data. We provide first results of this combination, including prototype displays for public access and data retrieval of water storage volume changes. Ground-based data can, in some cases, test the remote sensing accuracy and precision. Data accuracy requirements vary for different applications: reservoir management for flood control, agriculture, or power generation may need more accurate and timely information than (for example) regional assessments of water and food security issues. Thus, the long-term goal for the hydrological sciences community should be to efficiently mesh both types of information and with as extensive geographic coverage as possible.

Due to the ubiquity of cell phones, SMS (Short Message Service) has become an ideal means to wirelessly manage a Healthcare environment and in particular PACS (Picture Archival and Communications System) data. SMS is a flexible and mobile method for real-time access and control of Healthcare information systems such as HIS (Hospital Information System) or PACS. Unlike conventional wireless access methods, SMS' mobility is not limited by the presence of a WiFi network or any other localized signal. It provides a simple, reliable yet flexible method to communicate with an information system. In addition, SMS services are widely available for low costs from cellular phone service providers and allows for more mobility than other services such as wireless internet. This paper aims to describe a use case of SMS as a means of remotely communicating with a PACS server. Remote access to a PACS server and its Query-Retrieve services allows for a more convenient, flexible and streamlined radiology workflow. Wireless access methods such as SMS will increase dedicated PACS workstation availability for more specialized DICOM (Digital Imaging and Communications in Medicine) workflow management. This implementation will address potential security, performance and cost issues of applying SMS as part of a healthcare information management system. This is in an effort to design a wireless communication system with optimal mobility and flexibility at minimum material and time costs.

Power management of remote microgrids considering battery lifetime

NASA Astrophysics Data System (ADS)

Chalise, Santosh

Currently, 20% (1.3 billion) of the world's population still lacks access to electricity and many live in remote areas where connection to the grid is not economical or practical. Remote microgrids could be the solution to the problem because they are designed to provide power for small communities within clearly defined electrical boundaries. Reducing the cost of electricity for remote microgrids can help to increase access to electricity for populations in remote areas and developing countries. The integration of renewable energy and batteries in diesel based microgrids has shown to be effective in reducing fuel consumption. However, the operational cost remains high due to the low lifetime of batteries, which are heavily used to improve the system's efficiency. In microgrid operation, a battery can act as a source to augment the generator or a load to ensure full load operation. In addition, a battery increases the utilization of PV by storing extra energy. However, the battery has a limited energy throughput. Therefore, it is required to provide balance between fuel consumption and battery lifetime throughput in order to lower the cost of operation. This work presents a two-layer power management system for remote microgrids. First layer is day ahead scheduling, where power set points of dispatchable resources were calculated. Second layer is real time dispatch, where schedule set points from the first layer are accepted and resources are dispatched accordingly. A novel scheduling algorithm is proposed for a dispatch layer, which considers the battery lifetime in optimization and is expected to reduce the operational cost of the microgrid. This method is based on a goal programming approach which has the fuel and the battery wear cost as two objectives to achieve. The effectiveness of this method was evaluated through a simulation study of a PV-diesel hybrid microgrid using deterministic and stochastic approach of optimization.

Almost half of the world's total population reside in rural and remote areas and a large number of these people remain deprived of most basic facilities like healthcare and education. It is deemed impossible for government with scarce resources in developing countries to open and run a health facility in every remote community using conventional means. One increasingly popular unconventional mean is the use of existing technology to improve exchange of medical information for the purpose of improving health of underprivileged communities. Telemedicine implies the use of information and communication technology to provide health care remotely from a distance. With the induction of telemedicine, patients who live in rural and remote areas can have increased access to medical services. In many developing countries, use of telemedicine however has been limited mainly to teleconferencing between primary and secondary/tertiary care facilities for diagnosis and management of patients. This system still requires patients from remote communities to travel, often long and arduous journeys to the centre where telecom and medical facilities are available. Health Care 4 All International, a not for profit registered charity is providing primary care to patients by taking telemedicine into their homes in remote communities, thus obviating the need and hardships of travel for patient.

Design of a secure remote management module for a software-operated medical device.

Software-based medical devices need to be maintained throughout their entire life cycle. The efficiency of after-sales maintenance can be improved by managing medical systems remotely. This paper presents how to design the remote access function extensions in order to prevent risks imposed by uncontrolled remote access. A thorough analysis of standards and legislation requirements regarding safe operation and risk management of medical devices is presented. Based on the formal requirements, a multi-layer machine design solution is proposed that eliminates remote connectivity risks by strict separation of regular device functionalities from remote management service, deploys encrypted communication links and uses digital signatures to prevent mishandling of software images. The proposed system may also be used as an efficient version update of the existing medical device designs.

Remote access and care: A comparison of Queensland women's maternity care experience according to area of residence.

PubMed

Hennegan, Julie; Kruske, Sue; Redshaw, Maggie

2014-12-01

This study fills a gap in the literature with a quantitative comparison of the maternity care experiences of women in different geographic locations in Queensland, Australia. Data from a large-scale survey were used to compare women's care experiences according to Australian Standard Geographical Classification (major city, inner regional, outer regional, remote and very remote). Compared to the other groups, women from remote or very remote areas were more likely to be younger, live in an area with poorer economic resources, identify as Aboriginal and/or Torres Strait Islander and give birth in a public facility. They were more likely to travel to another city, town or community for birth. In adjusted analyses women from remote areas were less likely to have interventions such as electronic fetal monitoring, but were more likely to give birth in an upright position and be able to move around during labour. Women from remote areas did not differ significantly from women from major cities in their satisfaction with interpersonal care. Antenatal and postpartum care was lacking for rural women. In adjusted analyses they were much less likely to have booked for maternity care by 18 weeks gestation, to be telephoned or visited by a care provider in the first 10 days after birth. Despite these differences, women from remote areas were more likely to be breastfeeding at 13 weeks and confident in caring for their baby at home. Findings support qualitative assertions that remote and rural women are disadvantaged in their access to antenatal and postnatal care by the need to travel for birth, however, other factors such as age were more likely to be significant barriers to high quality interpersonal care. Improvements to maternity services are needed in order to address inequalities in maternity care particularly in the postnatal period. Copyright © 2014 Australian College of Midwives.

The amount of information contained in the data bases of large-scale information storage and retrieval systems is very large and growing at a rapid rate. The methods available for assessing this information have not been successful in making the information easily available to the people who have the greatest need for it. This thesis describes the design of a personal computer based system which will provide a means for these individuals to retrieve this data through one standardized interface. The thesis identifies each of the major problems associated with providing access to casual users of IS and R systems and describes the manner in which these problems are to be solved by the utilization of the local processing power of a PC. Additional capabilities, not available with standard access methods, are also provided to improve the user's ability to make use of this information. The design of PC/MISI is intended to facilitate its use as a research vehicle. Evaluation mechanisms and possible areas of future research are described. The PC/MISI development effort is part of a larger research effort directed at improving access to remote IS and R systems. This research effort, supported in part by NASA, is also reviewed.

Serving Satellite Remote Sensing Data to User Community through the OGC Interoperability Protocols

Remote sensing is one of the major methods for collecting geospatial data. Hugh amount of remote sensing data has been collected by space agencies and private companies around the world. For example, NASA's Earth Observing System (EOS) is generating more than 3 Tb of remote sensing data per day. The data collected by EOS are processed, distributed, archived, and managed by the EOS Data and Information System (EOSDIS). Currently, EOSDIS is managing several petabytes of data. All of those data are not only valuable for global change research, but also useful for local and regional application and decision makings. How to make the data easily accessible to and usable by the user community is one of key issues for realizing the full potential of these valuable datasets. In the past several years, the Open Geospatial Consortium (OGC) has developed several interoperability protocols aiming at making geospatial data easily accessible to and usable by the user community through Internet. The protocols particularly relevant to the discovery, access, and integration of multi-source satellite remote sensing data are the Catalog Service for Web (CS/W) and Web Coverage Services (WCS) Specifications. The OGC CS/W specifies the interfaces, HTTP protocol bindings, and a framework for defining application profiles required to publish and access digital catalogues of metadata for geographic data, services, and related resource information. The OGC WCS specification defines the interfaces between web-based clients and servers for accessing on-line multi-dimensional, multi-temporal geospatial coverage in an interoperable way. Based on definitions by OGC and ISO 19123, coverage data include all remote sensing images as well as gridded model outputs. The Laboratory for Advanced Information Technology and Standards (LAITS), George Mason University, has been working on developing and implementing OGC specifications for better serving NASA Earth science data to the user community for many years. We have developed the NWGISS software package that implements multiple OGC specifications, including OGC WMS, WCS, CS/W, and WFS. As a part of NASA REASON GeoBrain project, the NWGISS WCS and CS/W servers have been extended to provide operational access to NASA EOS data at data pools through OGC protocols and to make both services chainable in the web-service chaining. The extensions in the WCS server include the implementation of WCS 1.0.0 and WCS 1.0.2, and the development of WSDL description of the WCS services. In order to find the on-line EOS data resources, the CS/W server is extended at the backend to search metadata in NASA ECHO. This presentation reports those extensions and discuss lessons-learned on the implementation. It also discusses the advantage, disadvantages, and future improvement of OGC specifications, particularly the WCS.

A SOAP Web Service for accessing MODIS land product subsets

DOE Office of Scientific and Technical Information (OSTI.GOV)

SanthanaVannan, Suresh K; Cook, Robert B; Pan, Jerry Yun

2011-01-01

Remote sensing data from satellites have provided valuable information on the state of the earth for several decades. Since March 2000, the Moderate Resolution Imaging Spectroradiometer (MODIS) sensor on board NASA s Terra and Aqua satellites have been providing estimates of several land parameters useful in understanding earth system processes at global, continental, and regional scales. However, the HDF-EOS file format, specialized software needed to process the HDF-EOS files, data volume, and the high spatial and temporal resolution of MODIS data make it difficult for users wanting to extract small but valuable amounts of information from the MODIS record. Tomore » overcome this usability issue, the NASA-funded Distributed Active Archive Center (DAAC) for Biogeochemical Dynamics at Oak Ridge National Laboratory (ORNL) developed a Web service that provides subsets of MODIS land products using Simple Object Access Protocol (SOAP). The ORNL DAAC MODIS subsetting Web service is a unique way of serving satellite data that exploits a fairly established and popular Internet protocol to allow users access to massive amounts of remote sensing data. The Web service provides MODIS land product subsets up to 201 x 201 km in a non-proprietary comma delimited text file format. Users can programmatically query the Web service to extract MODIS land parameters for real time data integration into models, decision support tools or connect to workflow software. Information regarding the MODIS SOAP subsetting Web service is available on the World Wide Web (WWW) at http://daac.ornl.gov/modiswebservice.« less

OpenMSI: A High-Performance Web-Based Platform for Mass Spectrometry Imaging

DOE Office of Scientific and Technical Information (OSTI.GOV)

Rubel, Oliver; Greiner, Annette; Cholia, Shreyas

Mass spectrometry imaging (MSI) enables researchers to directly probe endogenous molecules directly within the architecture of the biological matrix. Unfortunately, efficient access, management, and analysis of the data generated by MSI approaches remain major challenges to this rapidly developing field. Despite the availability of numerous dedicated file formats and software packages, it is a widely held viewpoint that the biggest challenge is simply opening, sharing, and analyzing a file without loss of information. Here we present OpenMSI, a software framework and platform that addresses these challenges via an advanced, high-performance, extensible file format and Web API for remote data accessmore » (http://openmsi.nersc.gov). The OpenMSI file format supports storage of raw MSI data, metadata, and derived analyses in a single, self-describing format based on HDF5 and is supported by a large range of analysis software (e.g., Matlab and R) and programming languages (e.g., C++, Fortran, and Python). Careful optimization of the storage layout of MSI data sets using chunking, compression, and data replication accelerates common, selective data access operations while minimizing data storage requirements and are critical enablers of rapid data I/O. The OpenMSI file format has shown to provide >2000-fold improvement for image access operations, enabling spectrum and image retrieval in less than 0.3 s across the Internet even for 50 GB MSI data sets. To make remote high-performance compute resources accessible for analysis and to facilitate data sharing and collaboration, we describe an easy-to-use yet powerful Web API, enabling fast and convenient access to MSI data, metadata, and derived analysis results stored remotely to facilitate high-performance data analysis and enable implementation of Web based data sharing, visualization, and analysis.« less

Abstract Problem The Brazilian population lacks equitable access to specialized health care and diagnostic tests, especially in remote municipalities, where health professionals often feel isolated and staff turnover is high. Telehealth has the potential to improve patients’ access to specialized health care, but little is known about it in terms of cost-effectiveness, access to services or user satisfaction. Approach In 2005, the State Government of Minas Gerais, Brazil, funded the establishment of the Telehealth Network, intended to connect university hospitals with the state’s remote municipal health departments; support professionals in providing tele-assistance; and perform tele-electrocardiography and teleconsultations. The network uses low-cost equipment and has employed various strategies to overcome the barriers to telehealth use. Local setting The Telehealth Network connects specialists in state university hospitals with primary health-care professionals in 608 municipalities of the large state of Minas Gerais, many of them in remote areas. Relevant changes From June 2006 to October 2011, 782 773 electrocardiograms and 30 883 teleconsultations were performed through the network, and 6000 health professionals were trained in its use. Most of these professionals (97%) were satisfied with the system, which was cost-effective, economically viable and averted 81% of potential case referrals to distant centres. Lessons learnt To succeed, a telehealth service must be part of a collaborative network, meet the real needs of local health professionals, use simple technology and have at least some face-to-face components. If applied to health problems for which care is in high demand, this type of service can be economically viable and can help to improve patient access to specialized health care. PMID:22589571

Cardiovascular diseases are the leading cause of mortality in Indigenous Australians. Indigneous Australians present at a younger age and have a greater incidence of cardiac risk including smoking and diabetes than non-Indigenous Australians. Access to specialist health services is an important determinant of health care outcomes for these patients. We describe an innovative and successful for model for providing Outreach Cardiac Specialist services to Indigenous communities in rural and remote locations. The approach involves a step-wise process of a) community engagement, b) delivering recovery interventions to improve health outcomes, c) building community capacity to self manage chronic illness and promoting health and well being with the aim of d) community self governance of chronic disease and health promotion. Key elements to this process are community participation in the program, disease self-management led by local health care workers, open access that is all-inclusive utilising community-generated referral, and the translation of scientific knowledge of disease processes into community understanding and making culturally relevant connections. Specialist cardiac services and point of care diagnostics have been provided to 18 sites across rural and remote Queensland. More than 1400 episodes of care have been provided to Indigenous Australians with rheumatic heart disease, ischaemic heart disease and congenital heart conditions. Traditional values can work harmoniously with an inclusive medical approach in this relational model. Crown Copyright 2010. Published by Elsevier B.V. All rights reserved.

Challenges in managing postpartum hemorrhage in resource-poor countries.

PubMed

Karoshi, Mahantesh; Keith, Louis

2009-06-01

Managing postpartum hemorrhage depends in part on having a prepared mind, a complement of trained coworkers, and full access to modern therapies. The last 2 components are rare in resource-poor areas and their absence may be accentuated by climatic instability and lack of basic transportation. Greater use of the active management of third stage of labor and administration of misoprostol by nontrained birth attendants will provide beneficial reductions in hemorrhage rates in resource-poor areas. Additional improvements depend on increasing public awareness, facilitating existing nongovernmental organizations in their community-related, upgrading training of traditional birth attendants, and providing cell phone communication to workers in remote areas, in addition to providing better access to blood.

For more than a century Afghanistan has been unstable, facing decades of war, social problems, and intense poverty. As a result, many of the population suffer from a variety of mental health problems. The Government recognises the situation and has prioritised mental health, but progress is slow and services outside of Kabul remain poor. An international collaborative implemented a project in Badakshan province of Afghanistan using conventional and simple low-cost e-Health solutions to address the four most common issues: depression, psychosis, post-traumatic stress disorder, and substance abuse. Conventional town hall meetings informed community members to raise awareness and knowledge. In addition, an android-based mobile application used the World Health Organization's Mental Health Gap Action Programme guidelines and protocols to: collect information from community healthcare workers; provide referral services to patients; provide blended learning to improve providers' mental health knowledge, skills, and practice; and to provide store-and-forward and live consultations. Preliminary evaluation of the intervention shows enhanced access to care for remote communities, decreased stigma, and improved quality of health services. Primary care workers are also able to bridge the gap in consultations for rural and remote communities, connecting them with specialists and providing better access to care. © The Author(s) 2016.

Battlefield Medical Information System-Tactical (BMIST): the application of mobile computing technologies to support health surveillance in the Department of Defense.

2006-08-01

This paper discusses the innovation process of the Battlefield Medical Information System- Tactical (BMIST), a point-of-care mobile computing solution for reducing medical errors and improving the quality of care provided to our military personnel in the field. In such remote environments, medical providers have traditionally had limited access to medical information, a situation quite analogous to that in remote areas of underdeveloped or developing countries. BMIST provides an all-in-one suite of mobile applications that empowers providers via access to critical medical information and powerful clinical decision support tools to accurately create an electronic health record (EHR). This record is synchronized with Department of Defense (DOD) joint health surveillance and medical information systems from the earliest echelons of care through chronic care provided by the Veterans Administration. Specific goals met in the initial phase were: integration of the PDA and wireless interface; development of the local application and user interface; development of a communications infrastructure and development of a data storage and retrieval system. The system had been used extensively in the field to create an EHR far forward that supports a longitudinal medical record across time and across all elements of the Military Healthcare System.

Mars, Maurice

2015-01-01

Abstract Background: We investigated the use of third-generation (3G) mobile communications to provide telehealth services in remote health clinics in rural KwaZulu-Natal, South Africa. Materials and Methods: We specified a minimal set of services as our use case that would be representative of typical activity and to provide a baseline for analysis of network performance. Services included database access to manage chronic disease, local support and management of patients (to reduce unnecessary travel to the hospital), emergency care (up to 8 h for an ambulance to arrive), e-mail, access to up-to-date information (Web), and teleclinics. We made site measurements at a representative set of health clinics to determine the type of coverage (general packet radio service [GPRS]/3G), its capabilities to support videoconferencing (H323 and Skype™ [Microsoft, Redmond, WA]) and audio (Skype), and throughput for transmission control protocol (TCP) to gain a measure of application performance. Results: We found that none of the remote health clinics had 3G service. The GPRS service provided typical upload speed of 44 kilobits per second (Kbps) and download speed of 64 Kbps. This was not sufficient to support any form of videoconferencing. We also observed that GPRS had significant round trip time (RTT), in some cases in excess of 750 ms, and this led to slow start-up for TCP applications. Conclusions: We found audio was always so broken as to be unusable and further observed that many applications such as Web access would fail under conditions of very high RTT. We found some health clinics were so remote that they had no mobile service. 3G, where available, had measured upload speed of 331 Kbps and download speed of 446 Kbps and supported videoconferencing and audio at all sites, but we frequently experienced 3G changing to GPRS. We conclude that mobile communications currently provide insufficient coverage and capability to provide reliable clinical services and would advocate dedicated wireless services where reliable communication is essential and use of store and forward for mobile applications.

Remote monitoring technologies are ideally suited for rural communities with limited access to health care. In an 8-week pilot study, we examined the feasibility of implementing and conducting a technology-intensive intervention in an underserviced rural setting. Our goal was to test the utility of self-monitoring technologies, physical activity, and education as tools to manage health indicators for the development of the cardiovascular complications (CVCs) of type 2 diabetes. The Diabetes and Technology for Increased Activity study was an open single-center study conducted in a community-based research setting. All 24 participants were provided with a Blackberry™ Smartphone, blood pressure monitor, glucometer, and pedometer. Smartphones transmitted measurements and survey results to the database, interfaced participants with the clinical team, and allowed for self-monitoring. Outcomes were improved body composition, improved markers of CVC risk factors, increased daily exercise, and interest in or awareness of lifestyle changes that impact health outcomes. Participants had excellent compliance for measurements, as self-monitoring provided a sense of security that improved from week 4 to week 8. Our team gained substantial insight into the operational requirements of technology-facilitated health care, including redefined hours of service; data reporting, management, and access protocols; and the utility of real-time clinical measures by remote monitoring. We developed an understanding of knowledge translation strategies as well as successful motivational and educational tools. Importantly, remote monitoring technology was found to be feasible and accepted in a rural setting. © 2011 Diabetes Technology Society.

A combined year-round assessment of selected oceanographic data and a macrobiotic community assessment was performed from October 2013 to November 2014 in the littoral zone of the Kongsfjorden polar fjord system on the western coast of Svalbard (Norway). State of the art remote controlled cabled underwater observatory technology was used for daily vertical profiles of temperature, salinity, and turbidity together with a stereo-optical assessment of the macrobiotic community, including fish. The results reveal a distinct seasonal cycle in total species abundances, with a significantly higher total abundance and species richness during the polar winter when no light is available underwater compared to the summer months when 24 h light is available. During the winter months, a temporally highly segmented community was observed with respect to species occurrence, with single species dominating the winter community for restricted times. In contrast, the summer community showed an overall lower total abundance as well as a significantly lower number of species. The study clearly demonstrates the high potential of cable connected remote controlled digital sampling devices, especially in remote areas, such as polar fjord systems, with harsh environmental conditions and limited accessibility. A smart combination of such new digital sampling methods with classic sampling procedures can provide a possibility to significantly extend the sampling time and frequency, especially in remote and difficult to access areas. This can help to provide a sufficient data density and therefore statistical power for a sound scientific analysis without increasing the invasive sampling pressure in ecologically sensitive environments.

Northwestern Ontario in Canada provides a unique clinical challenge for providing optimal medical care. It is a large geographic area (385,000 km 2 ) and is home to 32 remote First Nations communities, most without road access. These communities suffer a heavy burden of infectious disease and specialist consultations are difficult to obtain. The Division of Infectious Diseases at the Ottawa Hospital and the Sioux Lookout Meno Ya Win Health Centre established a telemedicine-based infectious disease consultation service in July 2014. We describe the implementation of this service, types of cases seen and patient satisfaction, as well as some of the challenges encountered. Information on visits was prospectively collected through an administrative database, and patient satisfaction surveys were administered after each initial consultation. During our first year of operation, 191 teleconsultations occurred: 76 initial consultations, 82 follow-up appointments and 33 case conferences. The scope of cases has been broad, mostly involving musculoskeletal infections (26%), followed by skin and soft tissue infections (23%). HCV, acute rheumatic fever, and respiratory infections (including pulmonary tuberculosis) were other diagnoses. Patient satisfaction has been very high and 28 telemedicine patient visits have occurred in their remote home communities, minimizing travel. The infectious disease consulting service and local clinicians have succeeded in addressing needs for care in infectious diseases in northwestern Ontario, where important gaps in service to First Nations' communities continue to exist. Regular scheduled available access to an infectious disease specialist is a well-received advancement of care in this remote region of Canada.

Rural and remote speech-language pathology service inequities: An Australian human rights dilemma.

PubMed

Jones, Debra M; McAllister, Lindy; Lyle, David M

2018-02-01

Access to healthcare is a fundamental human right for all Australians. Article 19 of the Universal Declaration of Human Rights acknowledges the right to freedom of opinion and to seek, receive and impart information and ideas. Capacities for self-expression and effective communication underpin the realisation of these fundamental human rights. For rural and remote Australian children this realisation is compromised by complex disadvantages and inequities that contribute to communication delays, inequity of access to essential speech-language pathology services and poorer later life outcomes. Localised solutions to the provision of civically engaged, accessible, acceptable and sustainable speech-language pathology services within rural and remote Australian contexts are required if we are to make substantive human rights gains. However, civically engaged and sustained healthcare can significantly challenge traditional professionalised perspectives on how best to design and implement speech-language pathology services that seek to address rural and remote communication needs and access inequities. A failure to engage these communities in the identification of childhood communication delays and solutions to address these delays, ultimately denies children, families and communities of their human rights for healthcare access, self-expression, self-dignity and meaningful inclusion within Australian society.

A remote data access architecture for home-monitoring health-care applications.

2007-03-01

With the aging of the population and the increasing patient preference for receiving care in their own homes, remote home care is one of the fastest growing areas of health care in Taiwan and many other countries. Many remote home-monitoring applications have been developed and implemented to enable both formal and informal caregivers to have remote access to patient data so that they can respond instantly to any abnormalities of in-home patients. The aim of this technology is to give both patients and relatives better control of the health care, reduce the burden on informal caregivers and reduce visits to hospitals and thus result in a better quality of life for both the patient and his/her family. To facilitate their widespread adoption, remote home-monitoring systems take advantage of the low-cost features and popularity of the Internet and PCs, but are inherently exposed to several security risks, such as virus and denial-of-service (DoS) attacks. These security threats exist as long as the in-home PC is directly accessible by remote-monitoring users over the Internet. The purpose of the study reported in this paper was to improve the security of such systems, with the proposed architecture aimed at increasing the system availability and confidentiality of patient information. A broker server is introduced between the remote-monitoring devices and the in-home PCs. This topology removes direct access to the in-home PC, and a firewall can be configured to deny all inbound connections while the remote home-monitoring application is operating. This architecture helps to transfer the security risks from the in-home PC to the managed broker server, on which more advanced security measures can be implemented. The pros and cons of this novel architecture design are also discussed and summarized.

The unprecedented torrent of data returned by the Solar Dynamics Observatory is both a blessing and a barrier: a blessing for making available data with significantly higher spatial and temporal resolution, but a barrier for scientists to access, browse and analyze them. With such staggering data volume, the data is accessible only from a few repositories and users have to deal with data sets effectively immobile and practically difficult to download. From a scientist's perspective this poses three challenges: accessing, browsing and finding interesting data while avoiding the proverbial search for a needle in a haystack. To address these challenges, we have developed JHelioviewer, an open-source visualization software that lets users browse large data volumes both as still images and movies. We did so by deploying an efficient image encoding, storage, and dissemination solution using the JPEG 2000 standard. This solution enables users to access remote images at different resolution levels as a single data stream. Users can view, manipulate, pan, zoom, and overlay JPEG 2000 compressed data quickly, without severe network bandwidth penalties. Besides viewing data, the browser provides third-party metadata and event catalog integration to quickly locate data of interest, as well as an interface to the Virtual Solar Observatory to download science-quality data. As part of the ESA/NASA Helioviewer Project, JHelioviewer offers intuitive ways to browse large amounts of heterogeneous data remotely and provides an extensible and customizable open-source platform for the scientific community. In addition, the easy-to-use graphical user interface enables the general public and educators to access, enjoy and reuse data from space missions without barriers.

Providing Access to a Diverse Set of Global Reanalysis Dataset Collections

The National Center for Atmospheric Research (NCAR) Research Data Archive (RDA, http://rda.ucar.edu) provides open access to a variety of global reanalysis dataset collections to support atmospheric and related sciences research worldwide. These include products from the European Centre for Medium-Range Weather Forecasts (ECMWF), Japan Meteorological Agency (JMA), National Centers for Environmental Prediction (NCEP), National Oceanic and Atmospheric Administration (NOAA), and NCAR.All RDA hosted reanalysis collections are freely accessible to registered users through a variety of methods. Standard access methods include traditional browser and scripted HTTP file download. Enhanced downloads are available through the Globus GridFTP "fire and forget" data transfer service, which provides an efficient, reliable, and preferred alternative to traditional HTTP-based methods. For those that favor interoperable access using compatible tools, the Unidata THREDDS Data server provides remote access to complete reanalysis collections by virtual dataset aggregation "files". Finally, users can request data subsets and format conversions to be prepared for them through web interface form requests or web service API batch requests. This approach uses NCAR HPC and central file systems to effectively prepare products from the high-resolution and very large reanalyses archives. The presentation will include a detailed inventory of all RDA reanalysis dataset collection holdings, and highlight access capabilities to these collections through use case examples.

Using NetMeeting for remote configuration of the Otto Bock C-Leg: technical considerations.

Lemaire, E D; Fawcett, J A

Telehealth has the potential to be a valuable tool for technical and clinical support of computer controlled prosthetic devices. This pilot study examined the use of Internet-based, desktop video conferencing for remote configuration of the Otto Bock C-Leg. Laboratory tests involved connecting two computers running Microsoft NetMeeting over a local area network (IP protocol). Over 56 Kbs(-1), DSL/Cable, and 10 Mbs(-1) LAN speeds, a prosthetist remotely configured a user's C-Leg by using Application Sharing, Live Video, and Live Audio. A similar test between sites in Ottawa and Toronto, Canada was limited by the notebook computer's 28 Kbs(-1) modem. At the 28 Kbs(-1) Internet-connection speed, NetMeeting's application sharing feature was not able to update the remote Sliders window fast enough to display peak toe loads and peak knee angles. These results support the use of NetMeeting as an accessible and cost-effective tool for remote C-Leg configuration, provided that sufficient Internet data transfer speed is available.

Current methods of searching for and retrieving data from satellite land remote sensing archives do not allow for interactive information extraction. Instead, Earth science data users are required to download files over low-bandwidth networks to local workstations and process data before science questions can be addressed. New methods of extracting information from data archives need to become more interactive to meet user demands for deriving increasingly complex information from rapidly expanding archives. Moving the tools required for processing data to computer systems of data providers, and away from systems of the data consumer, can improve turnaround times for data processing workflows. The implementation of middleware services was used to provide interactive access to archive data. The goal of this middleware services development is to enable Earth science data users to access remote sensing archives for immediate answers to science questions instead of links to large volumes of data to download and process. Exposing data and metadata to web-based services enables machine-driven queries and data interaction. Also, product quality information can be integrated to enable additional filtering and sub-setting. Only the reduced content required to complete an analysis is then transferred to the user.

We constructed a remote radiation planning support system between Kyushu University Hospital (KUH) in Fukuoka and Kyushu University Beppu Hospital (KBH) in Oita. Between two institutions, radiology information system for radiotherapy division (RT-RIS) and radiation planning system (RTPS) were connected by virtual private network (VPN). This system enables the radiation oncologists at KUH to perform radiotherapy planning for the patients at KBH. The detail of the remote radiation planning support system in our institutions is as follows: The radiation oncologist at KBH performs radiotherapy planning and the data of the patients are sent anonymously to the radiation oncologists at KUH. The radiation oncologists at KUH receive the patient's data, access to RTPS at KBH, verify or change the radiation planning at KBH: Radiation therapy is performed at KBH according to the confirmed plan by the radiation oncologists at KUH. Our remote radiation planning system is useful for providing radiation therapy with safety and accuracy.

Imagery atlas: a structure of expert software designed to improve the accessibility of remote-sensed satellite imagery

Policy changes in the United States and Europe will bring a number of firms into the remote sensing market. More importantly, there will be a vast increase in the amount of data and potentially, the amount of information, that is available for academic, commercial and a variety of public uses. Presently many of the users of remote sensing data have some understanding of photogrammetric and remote sensing technologies. This is especially true of environmentalist users and academics. As the amount of remote sensing data increases, in order to broaden the user base, it will become increasingly important that the information user not be required to have a background in photogrammetry, remote sensing, or even in the basics of geographic information systems. The user must be able to articulate his requirements in view of existence of new sources of information. This paper provides the framework for expert systems to accomplish this interface. Specific examples of the capabilities which must be developed in order to maximize the utility of specific images and image archives are presented and discussed.

VOClient: Application Integration in the Virtual Observatory

Fitzpatrick, Michael J.; Tody, D.

2007-12-01

We present VOClient, a new software package that provides a high-level, easy-to-use, programmable interface between desktop applications and the distributed VO framework, providing access to remote VO data and services, reference implementations for VO data-providers and end-user applications. Applications have traditionally been written to deal directly with local images, catalogs or spectra; VOClient allows these applications to use remote VO data and services without requiring a developer to know the details of the underlying and evolving VO technologies. The programmable interface provides equivalent functionality for a wide variety of both legacy and modern development languages and environments and can be easily extended to add new functionality. The server component of the project provides a reference implementation and toolkit which can be used to build VO data services, and the commandline tools provide ready-to-use applications to access VO data and services from the desktop or scripting environment. The use of VOClient to integrate VO technologies with legacy systems such as IRAF is examined as a case-study, and the use of these techniques in other environments, especially their applicability to legacy code and systems, is also discussed. VOClient is meant both for the astronomer wishing to revive an old and trusted task with new VO capabiities, as well as the institutional project providing data or services to the Virtual Observatory.

Development of wide area environment accelerator operation and diagnostics method

NASA Astrophysics Data System (ADS)

Uchiyama, Akito; Furukawa, Kazuro

2015-08-01

Remote operation and diagnostic systems for particle accelerators have been developed for beam operation and maintenance in various situations. Even though fully remote experiments are not necessary, the remote diagnosis and maintenance of the accelerator is required. Considering remote-operation operator interfaces (OPIs), the use of standard protocols such as the hypertext transfer protocol (HTTP) is advantageous, because system-dependent protocols are unnecessary between the remote client and the on-site server. Here, we have developed a client system based on WebSocket, which is a new protocol provided by the Internet Engineering Task Force for Web-based systems, as a next-generation Web-based OPI using the Experimental Physics and Industrial Control System Channel Access protocol. As a result of this implementation, WebSocket-based client systems have become available for remote operation. Also, as regards practical application, the remote operation of an accelerator via a wide area network (WAN) faces a number of challenges, e.g., the accelerator has both experimental device and radiation generator characteristics. Any error in remote control system operation could result in an immediate breakdown. Therefore, we propose the implementation of an operator intervention system for remote accelerator diagnostics and support that can obviate any differences between the local control room and remote locations. Here, remote-operation Web-based OPIs, which resolve security issues, are developed.

The significant impact of mental ill health in rural and remote Australia has been well documented. Included among innovative approaches undertaken to address this issue has been the Mental Health Academic (MHA) project, established in 2007. Funded by the Australian Government (Department of Health), this project was established as a component of the University Departments of Rural Health (UDRH) program. All 11 UDRHs appointed an MHA. Although widely geographically dispersed, the MHAs have collaborated in various ways. The MHA project encompasses a range of activities addressing four key performance indicators. These activities, undertaken in rural and remote Australia, aimed to increase access to mental health services, promote awareness of mental health issues, support students undertaking mental health training and improve health professionals' capacity to recognise and address mental health issues. MHAs were strategically placed within the UDRHs across the country, ensuring an established academic base for the MHAs' work was available immediately. Close association with each local rural community was recognised as important. For most MHAs this was facilitated by having an established clinical role in their local community and actively engaging with the community in which they worked. In common with other rural health initiatives, some difficulties were experienced in the recruitment of suitable MHAs, especially in more remote locations. The genesis of this article was a national meeting of the MHAs in 2014, to identify and map the different types of activities MHAs had undertaken in their regions. These activities were analysed and categorised by the MHAs. These categories have been used as a guiding framework for this article. The challenge to increase community access to mental health services was addressed by (i) initiatives to address specific access barriers, (ii) supporting recruitment and retention of rural mental health staff, (iii) developing the skills of the existing workforce and (iv) developing innovative approaches to student placements. Strategies to promote awareness of mental health issues included workshops in rural and remote communities, specific suicide prevention initiatives and targeted initiatives to support the mental health needs of Indigenous Australians. The need for collaboration between the widely dispersed MHAs was identified as important to bridge the rural divide, to promote project cohesiveness and ensure new ideas in an emerging setting are readily shared and to provide professional support for one another as mental health academics are often isolated from academic colleagues with similar mental health interests. The MHA project suggests that an integrated approach can be taken to address the common difficulties of community awareness raising of mental health issues, increasing access to mental health services, workforce recruitment and retention (access), and skill development of existing health professionals (access and awareness). To address the specific needs and circumstances of their community, MHAs have customised their activities. As in other rural initiatives, one size was found not to fit all. The triad of flexibility, diversity and connectedness (both to local community and other MHAs) describes the response identified as appropriate by the MHAs. The breadth of the MHA role to provide university sponsored educational activities outside traditional student teaching meant that the broader health workforce benefited from access to mental health training that would not otherwise have occurred. Provision of these additional educational opportunities addressed not only the need for increased education regarding mental health but also reduced the barriers commonly faced by rural health professionals in accessing quality professional development.

Is Fly in/Fly out (FIFO) a viable interim solution to address remote medical workforce shortages?

PubMed

Margolis, Stephen A

2012-01-01

Geographically remote regions of Australia experience a higher degree of socioeconomic inequality and health inequity, amid poor resourcing and extreme climatic conditions, when compared with their more urban counterparts. Doctors with the knowledge, skills and interest in remote work remain a scarce resource, with only 58 practitioners per 100,000 people versus 196/100,000 in metropolitan areas. Pending the arrival of the full complement of long-term remote medical workforce, an alternative solution that has so far received little attention but could provide near equivalence to resident doctors is the 'fly in/fly out' (FIFO) model. Specifically, where one doctor has a continuous relationship with one town or community, albeit spending their rostered time off away from this location, rather than continuity of service with different doctors each time. In this model, doctors spend a fixed number of days at work geographically remote from their home and families, with logistical support (eg housing, transport) provided, followed by a fixed number of days back at home not working. This provides a the doctor with the benefits of remote clinical work plus guaranteed time off at home, a more acceptable roster than in many remote locations at present. This also avoids the complex issue of experienced doctors having to leave remote areas mid-career for the well-documented reasons of spouse employment and children's education, as well as providing easier access to professional development activities. The author followed this path and remains a FIFO doctor after 7 years of continuous service. For FIFO to be effective, there needs to be a commitment from the sponsoring organisation for short, balanced, flexible, family friendly rosters and a positive organizational structure with effective communication between management and front line staff. Evidence shows that families and children with healthy family functioning, who are able to balance separateness and togetherness and are able to readily adjust when circumstances move from stability through change, and have strong communication skills, cope well with FIFO work. The author's employer actively supports his FIFO work arrangements. Although FIFO presents challenges and is not for everyone, it may be time for organisations providing medical care to remote Australia to further consider this option. Allowing mid-career doctors experienced in remote medicine to continue remote clinical practice when they move to the city for family reasons would provide an immediate benefit to remote communities. Notwithstanding the challenges, perhaps it is time to consider the option of FIFO to address ongoing workforce shortages?

The Little Thompson Observatory is believed to be the first observatory built as part of a high school and accessible to other schools remotely, via the Internet. This observatory is the second member of the Telescopes in Education (TIE) project. Construction is nearly completed and first light is planned for fall 1998. The observatory is located on the grounds of Berthoud High School in northern Colorado. Local schools and youth organizations will have prioritized access to the telescope, and there will also be opportunities for public viewing. After midnight, the telescope will be open to world-wide use by schools via the Internet following the model of the first TIE observatory, the 24" telescope on Mt. Wilson. That telescope has been in use for the past four years by up to 50 schools per month. Students remotely connect to the observatory over the Internet, and then receive the images on their local computers. The observatory grew out of grassroots support from the local community surrounding Berthoud, Colorado, a town of 3,500 residents. TIE has provided the observatory with a Tinsley 18" Cassegrain telescope on a 10-year loan. The facility has been built with tremendous support from volunteers and the local school district. We have applied for an IDEAS grant to provide teacher training workshops which will allow K-12 schools in northern Colorado to make use of the Little Thompson Observatory, including remote observing from classrooms.

Access to health care in Canada's rural areas is a challenge. The Unité de Coordination Clinique des Services Préhospitaliers d'Urgence (UCCSPU) is a telemedicine program designed to improve health care in the Chaudiere-Appalaches and Quebec City regions of Canada. Remote medical services are provided by nurses and by an emergency physician based in a clinical unit at the Alphonse-Desjardins Community Health and Social Services Center. The interventions were developed to meet two objectives. The first is to enhance access to quality health care. To this end, Basic Life Support paramedics and nurses were taught interventions outside of their field of expertise. Prehospital electrocardiograms were used to remotely diagnose ST segment elevation myocardial infarction and to monitor patients who were en route by ambulance to the nearest catheterization facility or emergency department. Basic Life Support paramedics received extended medical authorization that allowed them to provide opioid analgesia via telemedicine physician orders. Nurses from community health centres without physician coverage were able to request medical assistance via a video telemedicine system. The second objective is to optimize medical resources. To this end, remote death certifications were implemented to avoid unnecessary transport of deceased persons to hospitals. This paper presents the telemedicine program and some results.

Consequently, application services rendering remote medical services and electronic health record (EHR) have become a hot topic and stimulating increased interest in studying this subject in recent years. Information and communication technologies have been applied to the medical services and healthcare area for a number of years to resolve problems in medical management. Sharing EHR information can provide professional medical programs with consultancy, evaluation, and tracing services can certainly improve accessibility to the public receiving medical services or medical information at remote sites. With the widespread use of EHR, building a secure EHR sharing environment has attracted a lot of attention in both healthcare industry and academic community. Cloud computing paradigm is one of the popular healthIT infrastructures for facilitating EHR sharing and EHR integration. In this paper, we propose an EHR sharing and integration system in healthcare clouds and analyze the arising security and privacy issues in access and management of EHRs.

Hip fractures are associated with considerable morbidity and mortality. Hip fracture incidence varies across different levels of accessibility/remoteness and socioeconomic status (SES). As part of the Ageing, Chronic Disease and Injury Study, we aimed to map the pattern of hip fractures across the western region of the Australian state of Victoria, which contains a range of remoteness levels and SES. Data on hip fractures resulting in hospital admission were extracted from the Victorian Admitted Episodes Dataset (VAED) for men and women aged 40+years during 2010-2013 inclusive. An age-adjusted incidence rate (per 10,000population/year) was calculated for the entire region. Crude incidence rates and length of acute care hospital stay (excluding rehabilitation) were calculated for each Local Government Area (LGA). The impact of aggregated age, accessibility/remoteness index of Australia (ARIA) and SES on hip fracture rates aggregated across LGAs was determined using Poisson regression. For men, the age-standardised rate of hospitalisations for hip fracture across the whole region was 19.2 per 10,000population/year (95%CI 18.0-20.4) and for women, 40.0 (95%CI 38.3-41.7). The highest incidence rates for both sexes occurred in the less accessible LGAs of Yarriambiack and Hindmarsh, as well as the LGA with the lowest SES, Central Goldfields. In both sexes, approximately two thirds of individuals were discharged from acute hospital care within 14days. Increasing age, higher remoteness and lower SES were all associated with higher hip fracture rates. Crude incidence rates varied by location. Given that a high proportion of patients had acute hospital care of ≤14days, and accessibility and SES were associated with hip fracture rates, these results can inform policy and provide a model for other groups to conduct similar research in their local environment.

Telemedicine-based approaches to health care service delivery improve access to care. It was recognized that adults with inflammatory arthritis (IA) living in remote areas had limited access to patient education and could benefit from the 1-day Prescription for Education (RxEd) program. The program was delivered by extended role practitioners with advanced training in arthritis care. Normally offered at one urban center, RxEd was adapted for videoconference delivery through two educator development workshops that addressed telemedicine and adult education best practices. This study explores the feasibility of and participant satisfaction with telemedicine delivery of the RxEd program in remote communities. Participants included adults with IA attending the RxEd program at one of six rural sites. They completed post-course program evaluations and follow-up interviews. Educators provided post-course feedback to identify program improvements that were later implemented. In total, 123 people (36 in-person and 87 remote, across 6 sites) participated, attending one of three RxEd sessions. Remote participants were satisfied with the quality of the video-conference (% agree/strongly agree): could hear the presenter (92.9%) and discussion between sites (82.4%); could see who was speaking at other remote sites (85.7%); could see the slides (95.3%); and interaction between sites adequately facilitated (94.0%). Educator and participant feedback were consistent. Suggested improvements included: use of two screens (speaker and slides); frontal camera angles; equal interaction with remote sites; and slide modifications to improve the readability on screen. Interview data included similar constructive feedback but highlighted the educational and social benefits of the program, which participants noted would have been inaccessible if not offered via telemedicine. Study findings confirm the feasibility of delivering the RxEd program to remote communities by using telemedicine. Future research with a focus on the sustainability of this and other models of technology-supported patient education for adults with IA across Ontario is warranted.

Lawhead, Joel

2007-01-01

BasinTools Module 1 processes remotely sensed raster data, including multi- and hyper-spectral data products, via a Web site with no downloads and no plug-ins required. The interface provides standardized algorithms designed so that a user with little or no remote-sensing experience can use the site. This Web-based approach reduces the amount of software, hardware, and computing power necessary to perform the specified analyses. Access to imagery and derived products is enterprise-level and controlled. Because the user never takes possession of the imagery, the licensing of the data is greatly simplified. BasinTools takes the "just-in-time" inventory control model from commercial manufacturing and applies it to remotely-sensed data. Products are created and delivered on-the-fly with no human intervention, even for casual users. Well-defined procedures can be combined in different ways to extend verified and validated methods in order to derive new remote-sensing products, which improves efficiency in any well-defined geospatial domain. Remote-sensing products produced in BasinTools are self-documenting, allowing procedures to be independently verified or peer-reviewed. The software can be used enterprise-wide to conduct low-level remote sensing, viewing, sharing, and manipulating of image data without the need for desktop applications.

Access to expert practitioners or geographic distance can compound the capacity for appropriate supervision of health professionals in the workplace. Guidance and support of clinicians and students to undertake new or infrequent procedures can be resource intensive. The Helping Hands remote augmented reality system is an innovation to support the development of, and oversee the acquisition of procedural skills through remote learning and teaching supervision while in clinical practice. Helping Hands is a wearable, portable, hands-free, low cost system comprised of two networked laptops, a head-mounted display worn by the recipient and a display screen used remotely by the instructor. Hand hygiene was used as the test procedure as it is a foundation skill learned by all health profession students. The technology supports unmediated remote gesture guidance by augmenting the object with the Helping Hands of a health professional. A laboratory-based study and field trial tested usability and feasibility of the remote guidance system. The study found the Helping Hands system did not compromise learning outcomes. This innovation has the potential to transform remote learning and teaching supervision by enabling health professionals and students opportunities to develop and improve their procedural performance at the workplace.

Exchange of Veterans Affairs medical data using national and local networks.

PubMed

Dayhoff, R E; Maloney, D L

1992-12-17

Remote data exchange is extremely useful to a number of medical applications. It requires an infrastructure including systems, network and software tools. With such an infrastructure, existing local applications can be extended to serve national needs. There are many approaches to providing remote data exchange. Selection of an approach for an application requires balancing of various factors, including the need for rapid interactive access to data and ad hoc queries, the adequacy of access to predefined data sets, the need for an integrated view of the data, the ability to provide adequate security protection, the amount of data required, and the time frame in which data is required. The applications described here demonstrate new ways that the VA is reaping benefits from its infrastructure and its compatible integrated hospital information systems located at its facilities. The needs that have been met are also needs of private hospitals. However, in many cases the infrastructure to allow data exchange is not present. The VA's experiences may serve to establish the benefits that can be obtained by all hospitals.

The Role of Health Kiosks in 2009: Literature and Informant Review

Jones, Ray

2009-01-01

Kiosks can provide patients with access to health systems in public locations, but with increasing home Internet access their usefulness is questioned. A literature and informant review identified kiosks used for taking medical histories, health promotion, self assessment, consumer feedback, patient registration, patient access to records, and remote consultations. Sited correctly with good interfaces, kiosks can be used by all demographics but many ‘projects’ have failed to become routine practice. A role remains for: (a) integrated kiosks as part of patient ‘flow’, (b) opportunistic kiosks to catch people’s attention. Both require clear ‘ownership’ to succeed. PMID:19578463

Isolated communities in remote regions of Afghanistan, Kyrgyz Republic, Pakistan and Tajikistan lack access to high-quality, low-cost health care services, forcing them to travel to distant parts of the country, bearing an unnecessary financial burden. The eHealth Programme under Central Asia Health Systems Strengthening (CAHSS) Project, a joint initiative between the Aga Khan Foundation, Canada and the Government of Canada, was initiated in 2013 with the aim to utilize Information and Communication Technologies to link health care institutions and providers with rural communities to provide comprehensive and coordinated care, helping minimize the barriers of distance and time. Under the CAHSS Project, access to low-cost, quality health care is provided through a regional hub and spoke teleconsultation network of government and non-government health facilities. In addition, capacity building initiatives are offered to health professionals. By 2017, the network is expected to connect seven Tier 1 tertiary care facilities with 14 Tier 2 secondary care facilities for teleconsultation and eLearning. From April 2013 to September 2014, 6140 teleconsultations have been provided across the project sites. Additionally, 52 new eLearning sessions have been developed and 2020 staff members have benefitted from eLearning sessions. Ethics and patient rights are respected during project implementation.

BCM Search Launcher--an integrated interface to molecular biology data base search and analysis services available on the World Wide Web.

The BCM Search Launcher is an integrated set of World Wide Web (WWW) pages that organize molecular biology-related search and analysis services available on the WWW by function, and provide a single point of entry for related searches. The Protein Sequence Search Page, for example, provides a single sequence entry form for submitting sequences to WWW servers that offer remote access to a variety of different protein sequence search tools, including BLAST, FASTA, Smith-Waterman, BEAUTY, PROSITE, and BLOCKS searches. Other Launch pages provide access to (1) nucleic acid sequence searches, (2) multiple and pair-wise sequence alignments, (3) gene feature searches, (4) protein secondary structure prediction, and (5) miscellaneous sequence utilities (e.g., six-frame translation). The BCM Search Launcher also provides a mechanism to extend the utility of other WWW services by adding supplementary hypertext links to results returned by remote servers. For example, links to the NCBI's Entrez data base and to the Sequence Retrieval System (SRS) are added to search results returned by the NCBI's WWW BLAST server. These links provide easy access to auxiliary information, such as Medline abstracts, that can be extremely helpful when analyzing BLAST data base hits.

Assessing the Interdisciplinary Use of Socioeconomic and Remote Sensing Data in the Earth Sciences

NASA Astrophysics Data System (ADS)

Chen, R. S.; Downs, R. R.; Schumacher, J.

2013-12-01

Remotely sensed data are widely used in Earth science research and applications not just to improve understanding of natural systems but also to elucidate interactions between natural and human systems and to model and predict human impacts on the environment, whether planned or unplanned. It is therefore often necessary for both remote sensing and socioeconomic data to be used together in both Earth science and social science research, for example in modeling past, present, and future land cover change, in assessing societal vulnerability to geophysical and climatological hazards, in measuring the human health impacts of air and water pollution, or in developing improved approaches to managing water, ecological, and other resources. The NASA Socioeconomic Data and Applications Center (SEDAC) was established as part of the Earth Observing System Data and Information System (EOSDIS) to facilitate access to and use of socioeconomic data in conjunction with remote sensing data in both research and applications. SEDAC provides access both to socioeconomic data that have been transformed into forms more readily usable by Earth scientists and other users, and to integrated datasets that incorporate both socioeconomic and remote sensing data. SEDAC data have been cited in at least 2,000 scientific papers covering a wide range of scientific disciplines and problem areas. In many cases, SEDAC data are cited in these papers along with other remote sensing datasets available from NASA or other sources. However, such citations do not necessarily indicate significant, integrated use of SEDAC and remote sensing data. To assess the level and type of integrated data use, we analyze a selection of recent SEDAC data citations in Earth science journals to characterize the ways in which SEDAC data have been used in the underlying research project and the paper itself. Papers were selected based on the presence of a SEDAC data citation and one or more keywords related to a remote sensing instrument or dataset. We assess if and how the SEDAC and remote sensing data are used together, e.g., in an empirical analysis, model, and/or visualization. We also ascertain the multidisciplinary backgrounds of the author or authors, as well as the Web of Science category and impact factor associated with the journal, to help characterize the user community and the overall scientific impact of the data use. Another issue is whether or not authors are formally citing SEDAC data and remote sensing in reference sections as opposed to referring to data informally, e.g., in figure captions. A key challenge in promoting the cross-disciplinary use of scientific data is the identification of ways in which scientists and other users not only access data from other disciplines but also use these data in their research. Objective assessment of scientific outputs such as the peer-reviewed scientific literature provides important insight into how individual scientists and scientific teams are taking advantage of the ongoing explosion in the variety and quantity of digital data from multiple disciplines to address pressing research problems and applications.

To investigate the challenges of providing oral health advice/treatment as experienced by non-dental primary care providers in rural and remote areas with no resident dentist, and their views on ways in which oral health and oral health services could be improved for their communities. Qualitative study with semistructured interviews and thematic analysis. Four remote communities in outback Queensland, Australia. 35 primary care providers who had experience in providing oral health advice to patients and four dental care providers who had provided oral health services to patients from the four communities. In the absence of a resident dentist, rural and remote residents did present to non-dental primary care providers with oral health problems such as toothache, abscess, oral/gum infection and sore mouth for treatment and advice. Themes emerged from the interview data around communication challenges and strategies to improve oral health. Although, non-dental care providers commonly advised patients to see a dentist, they rarely communicated with the dentist in the nearest regional town. Participants proposed that oral health could be improved by: enabling access to dental practitioners, educating communities on preventive oral healthcare, and building the skills and knowledge base of non-dental primary care providers in the field of oral health. Prevention is a cornerstone to better oral health in rural and remote communities as well as in more urbanised communities. Strategies to improve the provision of dental services by either visiting or resident dental practitioners should include scope to provide community-based oral health promotion activities, and to engage more closely with other primary care service providers in these small communities.

Korea Astronomy and Space Science Institute (KASI) has been developing one mobile and one stationary SLR system since 2008 named as ARGO-M and ARGO-F, respectively. KASI finished the step of deriving the system requirements of ARGO. The requirements include definitions and scopes of various software and hardware components which are necessary for developing the ARGO-M operation system. And the requirements define function, performance, and interface requirements. The operation system consisting of ARGO-M site, ARGO-F site, and Remote Operation Center (ROC) inside KASI is designed for remote access and the automatic tracking and control system which are the main operation concept of ARGO system. To accomplish remote operation, we are considering remote access to ARGO-F and ARGO-M from ROC. The mobile-phone service allows us to access the ARGO-F remotely and to control the system in an emergency. To implement fully automatic tracking and control function in ARGO-F, we have investigated and described the requirements about the automatic aircraft detection system and the various meteorological sensors. This paper addresses the requirements of ARGO Operation System.

2006-05-01

The Unidata Program Center (Unidata) of the University Corporation of Atmospheric Research (UCAR) is actively involved in international collaborations whose goals are real-time sharing of hydro-meteorological data by institutions of higher education throughout the Americas; in the distribution of analysis and visualization tools for those data; and in the establishment of server sites that provide easy-to-use, programmatic remote- access to a wide variety of datasets. Data sharing capabilities are being provided by Unidata's Internet Data Distribution (IDD) system, a community-based effort that has been the primary source of real-time meteorological data for approximately 150 US universities for over a decade. A collaboration among Unidata, Brazil's Centro de PreviSão de Tempo e Estudos Climáticos (CPTEC), the Universidad Federal do Rio de Janeiro (UFRJ), and the Universidade de São Paulo (USP) has resulted in the creation of a Brazilian peer of the North American IDD, the IDD-Brasil. Collaboration among Unidata, the Universidad de Costa Rica (UCR), and the University of Puerto Rico at Mayaguez (UPRM) seeks to extend IDD data sharing throughout Central America and the Caribbean in an IDD-Caribe. Collaboration between Unidata and the Caribbean Institute for Meteorology and Hydrology (CIMH), a World Meteorological Organization (WMO) Regional Meteorological Training Center (RMTC) based in Barbados, has been launched to investigate the possibility of expansion of IDD data sharing throughout Caribbean RMTC member countries. Most recently, efforts aimed at creating a data sharing network for researchers on the Antarctic continent have resulted in the establishment of the Antarctic-IDD. Data analysis and visualization capabilities are being provided by Unidata through a suite of freely-available applications: the National Centers for Environmental Prediction (NCEP) GEneral Meteorology PAcKage (GEMPAK); the Unidata Integrated Data Viewer (IDV); and University of Wisconsin, Space Science and Engineering Center (SSEC) Man-computer Interactive Data Access System (McIDAS). Remote data access capabilities are provided by Unidata's Thematic Realtime Environmental Data Services (THREDDS) servers (which incorporate Open-source Project for a Network Data Access (OPeNDAP) data services), and the Abstract Data Distribution Environment (ADDE) of McIDAS. It is envisioned that the data sharing capabilities available in the IDD, IDD-Brasil, and IDD-Caribe, remote data access capabilities available in THREDDS and ADDE, and analysis capabilities available in GEMPAK, the IDV, and McIDAS will help foster new collaborations among prominent university educators and researchers, national meteorological agencies, and WMO Regional Meteorological Training Centers throughout North, Central, and South America.

Low socioeconomic status (SES) and geographic disparity have been associated with worse outcomes and poorer access to pre-emptive transplantation in the adult end-stage kidney disease (ESKD) population, but little is known about their impact in children with ESKD. The aim of our study was to determine whether access to pre-emptive transplantation and transplant outcomes differ according to SES and geographic remoteness in Australia. Using data from the Australia and New Zealand Dialysis and Transplant Registry (1993-2012), we compared access to pre-emptive transplantation, the risk of acute rejection and graft failure, based on SES and geographic remoteness among Australian children with ESKD (≤ 18 years), using adjusted logistic and Cox proportional hazard modelling. Of the 768 children who commenced renal replacement therapy, 389 (50.5%) received living donor kidney transplants and 28.5% of these (111/389) were pre-emptive. There was no significant association between SES quintiles and access to pre-emptive transplantation, acute rejection or allograft failure. Children residing in regional or remote areas were 35% less likely to receive a pre-emptive transplant compared to those living in major cities [adjusted odds ratio (OR) 0.65, 95% confidence interval (CI) 0.45-1.0]. There was no significant association between geographic disparity and acute rejection (adjusted OR 1.03, 95% CI 0.68-1.57) or graft loss (adjusted hazard ratio 1.05, 95% CI 0.74-1.41). In Australia, children from regional or remote regions are much less likely to receive pre-emptive kidney transplantation. Strategies such as improved access to nephrology services through expanding the scope of outreach clinics, and support for regional paediatricians to promote early referral may ameliorate this inequity.

Objectives To pilot test and evaluate a gas chromatography-mass spectrometry (GCMS) case study as a teaching and learning tool. Design A case study incorporating remote access to a GCMS instrument through the Integrated Laboratory Network (ILN) at Western Washington University was developed and implemented. Student surveys, faculty interviews, and examination score data were used to evaluate learning. Assessment While the case study did not impact final examination scores, approximately 70% of students and all faculty members felt the ILN-supported case study improved student learning about GCMS. Faculty members felt the “live” instrument access facilitated more authentic teaching. Students and faculty members felt the ILN should continue to be developed as a teaching tool. Conclusion Remote access to scientific instrumentation can be used to modify case studies to enhance student learning and teaching practice in pharmaceutical analysis. PMID:17149450

An autonomous remote clock control system is proposed to provide time synchronization and frequency syntonization for satellite to satellite or ground to satellite time transfer, with the system comprising on-board voltage controlled oven controlled crystal oscillators (VC-OCXOs) that are disciplined to a remote master atomic clock or oscillator. The synchronization loop aims to provide autonomous operation over extended periods, be widely applicable to a variety of scenarios and robust. A new architecture comprising the use of frequency division duplex (FDD), synchronous time division (STDD) duplex and code division multiple access (CDMA) with a centralized topology is employed. This new design utilizes dual one-way ranging methods to precisely measure the clock error, adopts least square (LS) methods to predict the clock error and employs a third-order phase lock loop (PLL) to generate the voltage control signal. A general functional model for this system is proposed and the error sources and delays that affect the time synchronization are discussed. Related algorithms for estimating and correcting these errors are also proposed. The performance of the proposed system is simulated and guidance for selecting the clock is provided.

Emerging technologies have provided unprecedented opportunities to transform information into knowledge and disseminate them in a much faster, cheaper, and userfriendly mode. We have set up a system to produce and disseminate high level (gridded) ocean surface wind data from the NASA Scatterometer and European Remote Sensing missions. The data system is being expanded to produce real-time gridded ocean surface winds from an improved sensor SeaWinds on the Quikscat Mission. The wind field will be combined with hydrologic parameters from the Tropical Rain Measuring Mission to monitor evolving weather systems and natural hazard in real time. It will form the basis for spacebased Ocean Surface Exchange Data Analysis System (SOSEDAS) which will include the production of ocean surface momentum, heat, and water fluxes needed for interdisciplinary studies of ocean-atmosphere interaction. Various commercial or non-commercial software tools have been compared and selected in terms of their ability in database management, remote data accessing, graphical interface, data quality, storage needs and transfer speed, etc. Issues regarding system security and user authentication, distributed data archiving and accessing, strategy to compress large-volume geophysical and satellite data/image. and increasing transferring speed are being addressed. A simple and easy way to access information and derive knowledge from spacebased data of multiple missions is being provided. The evolving 'knowledge system' will provide relevant infrastructure to address Earth System Science, make inroads in educating an informed populace, and illuminate decision and policy making.

Brown, Molly E.; Brickley, Elizabeth B.

2011-01-01

The US Agency for International Development (USAID) s Famine Early Warning System Network (FEWS NET) provides monitoring and early warning support to decision makers responsible for responding to food insecurity emergencies on three continents. FEWS NET uses satellite remote sensing and ground observations of rainfall and vegetation in order to provide information on drought, floods and other extreme weather events to decision makers. Previous research has presented results from a professional review questionnaire with FEWS NET expert end-users whose focus was to elicit Earth observation requirements. The review provided FEWS NET operational requirements and assessed the usefulness of additional remote sensing data. Here we analyzed 1342 food security update reports from FEWS NET. The reports consider the biophysical, socioeconomic, and contextual influences on the food security in 17 countries in Africa from 2000-2009. The objective was to evaluate the use of remote sensing information in comparison with other important factors in the evaluation of food security crises. The results show that all 17 countries use rainfall information, agricultural production statistics, food prices and food access parameters in their analysis of food security problems. The reports display large scale patterns that are strongly related to history of the FEWS NET program in each country. We found that rainfall data was used 84% of the time, remote sensing of vegetation 28% of the time, and gridded crop models 10%, reflecting the length of use of each product in the regions. More investment is needed in training personnel on remote sensing products to improve use of data products throughout the FEWS NET system.

We developed advanced communications and networking capability and satellite reception systems for Earth science to improve the ability of scientists at Scripps Institution of Oceanography (SIO) to conduct interdisciplinary research. With matching funds from the SIO Director's office we implemented a "virtual center" utilizing modern networking hardware and software to enhance access for researchers and students to unique satellite and in situ data sets. The center provides facilities and data access to graduate students as well as research scientists at SIO, and outside SIO. Our private sector partners installed and testes and advanced X-band data acquisition system for satellite data capture relevant for Earth science research and applications. Some of the commercial applications of these partners have been developed (or are under development) with NASA SBIR resources. The X-band system collected RADARSAT, ERS-2 and MODIS imagery. Perhaps most importantly, this COE brought together - for the first time - an interdisciplinary team of SIO scientists with interests in Earth remote sensing. The collaboration extended beyond our infrastructure and research accomplishments leading to a dialog that resulted in a report with strong recommendations to the SIO community for enhancing satellite remote sensing at SIO.

Setting up home-based palliative care in countries with limited resources: a model from Sarawak, Malaysia.

Devi, B C R; Tang, T S; Corbex, M

2008-12-01

The provision of palliative care (PC) and opioids is difficult to ensure in remote areas in low- and middle-income countries. We describe here the set up of a home-care program in Sarawak (the Malaysian part of the Borneo Island), where half the population lives in villages that are difficult to access. The establishment of this program, initiated in 1994 by the Department of Radiotherapy of Sarawak General Hospital, consisted of training, empowering nurses, simplifying referral, facilitating access to medication, and increasing awareness among public and health professionals about PC. The program has been sustainable and cost efficient, serving 936 patients in 2006. The total morphine usage in the program increased from <200 g in 1993 to >1400 g in 2006. The results show that pain medication can be provided even in remote areas with effective organization and empowerment of nurses, who were the most important determinants for the set up of this program. Education of family was also a key aspect. The authors believe that the experience gained in Sarawak may help other regions with low or middle resources in the set up of their PC program especially for their remote rural population.

There is an urgent need for healthcare research, funding, and infrastructure in the Peruvian Amazon. We performed a descriptive study of health, health knowledge and practice, and healthcare access of 13 remote communities of the Manatí and Amazon Rivers in northeastern Peru. Eighty-five adults attending a medical boat service were interviewed to collect data on socioeconomic position, health, diagnosed illnesses, pain, healthcare access, and traditional versus modern medicine use. In this setting, poverty and gender inequality were prevalent, and healthcare access was limited by long distances to the health post and long waiting times. There was a high burden of reported pain (mainly head and musculoskeletal) and chronic non-communicable diseases, such as hypertension (19%). Nearly all participants felt that they did not completely understand their diagnosed illnesses and wanted to know more. Participants preferred modern over traditional medicine, predominantly because of mistrust or lack of belief in traditional medicine. Our findings provide novel evidence concerning transitional health beliefs, hidden pain, and chronic non-communicable disease prevalence in marginalized communities of the Peruvian Amazon. Healthcare provision was limited by a breach between health education, knowledge, and access. Additional participatory research with similar rural populations is required to inform regional healthcare policy and decision-making. © The American Society of Tropical Medicine and Hygiene.

Integrating NASA Earth Science Enterprise (ESE) Data Into Global Agricultural Decision Support Systems

Monitoring global agricultural crop conditions during the growing season and estimating potential seasonal production are critically important for market development of U.S. agricultural products and for global food security. Two major operational users of satellite remote sensing for global crop monitoring are the USDA Foreign Agricultural Service (FAS) and the U.N. World Food Programme (WFP). The primary goal of FAS is to improve foreign market access for U.S. agricultural products. The WFP uses food to meet emergency needs and to support economic and social development. Both use global agricultural decision support systems that can integrate and synthesize a variety of data sources to provide accurate and timely information on global crop conditions. The Goddard Space Flight Center Earth Sciences Distributed Active Archive Center (GES DAAC) has begun a project to provide operational solutions to FAS and WFP, by fully leveraging results from previous work, as well as from existing capabilities of the users. The GES DAAC has effectively used its recently developed prototype TRMM Online Visualization and Analysis System (TOVAS) to provide ESE data and information to the WFP for its agricultural drought monitoring efforts. This prototype system will be evolved into an Agricultural Information System (AIS), which will operationally provide ESE and other data products (e.g., rainfall, land productivity) and services, to be integrated into and thus enhance the existing GIS-based, decision support systems of FAS and WFP. Agriculture-oriented, ESE data products (e.g., MODIS-based, crop condition assessment product; TRMM derived, drought index product) will be input to a crop growth model in collaboration with the USDA Agricultural Research Service, to generate crop condition and yield prediction maps. The AIS will have the capability for remotely accessing distributed data, by being compliant with community-based interoperability standards, enabling easy access to agriculture-related products from other data producers. The AIS? system approach will provide a generic mechanism for easily incorporating new products and making them accessible to users.

The International Ultraviolet Explorer (IUE) Science Operations System provides full realtime operations capabilities and support to the operations staff and astronomer users. The components of this very diverse and extremely flexible hardware and software system have played a major role in maintaining the scientific efficiency and productivity of the IUE. The software provides the staff and user with all the tools necessary for pre-visit and real-time planning and operations analysis for any day of the year. Examples of such tools include the effects of spacecraft constraints on target availability, maneuver times between targets, availability of guide stars, target identification, coordinate transforms, e-mail transfer of Observatory forms and messages, and quick-look analysis of image data. Most of this extensive software package can also be accessed remotely by individual users for information, scheduling of shifts, pre-visit planning, and actual observing program execution. Astronomers, with a modest investment in hardware and software, may establish remote observing sites. We currently have over 20 such sites in our remote observers' network.

The focus in development of a new generation of middleware shifts from the global grid systems to building convenient and efficient web platforms for remote access to individual computing resources. Further line of their development, suggested in this work, is related not only with the quantitative increase in their number and with the expansion of scientific, engineering, and manufacturing areas in which they are used, but also with improved technology for remote deployment of application software on the resources interacting with the web platforms. Currently, the services for providers of application software in the context of scientific-oriented web platforms is not developed enough. The proposed in this work new web platforms of application software market should have all the features of the existing web platforms for submissions of jobs to remote resources plus the provision of specific web services for interaction on market principles between the providers and consumers of application packages. The suggested approach will be approved on the example of simulation applications in the field of nonlinear optics.

New Directions in Land Remote Sensing Policy and International Cooperation

Recent changes to land remote sensing satellite data policies in Brazil and the United States have led to the phenomenal growth in the delivery of land imagery to users worldwide. These new policies, which provide free and unrestricted access to land remote sensing data over a standard electronic interface, are expected to provide significant benefits to scientific and operational users, and open up new areas of Earth system science research and environmental monitoring. Freely-available data sets from the China-Brazil Earth Resources Satellites (CBERS), the U.S. Landsat satellites, and other satellite missions provide essential information for land surface monitoring, ecosystems management, disaster mitigation, and climate change research. These missions are making important contributions to the goals and objectives of regional and global terrestrial research and monitoring programs. These programs are in turn providing significant support to the goals and objectives of the United Nations Framework Convention on Climate Change (UN FCCC), the Global Earth Observation System of Systems (GEOSS), and the UN Reduction in Emissions from Deforestation and Degradation (REDD) program. These data policies are well-aligned with the "Data Democracy" initiative undertaken by the international Committee on Earth Observation Satellites (CEOS), through its current Chair, Brazil's National Institute for Space Research (Instituto Nacional de Pesquisas Espaciais, or INPE), and its former chairs, South Africa's Council for Scientific and Industrial Research (CSIR) and Thailand's Geo Informatics and Space Technology Development Agency (GISTDA). Comparable policies for land imaging data are under consideration within Europe and Canada. Collectively, these initiatives have the potential to accelerate and improve international mission collaboration, and greatly enhance the access, use, and application of land surface imagery for environmental monitoring and societal adaption to changing climate conditions.

Remote Observational Techniques in Education

The ability to observe celestial objects remotely is making a major impact into classroom access to astronomical instrumentation previously impossible to encorporate into curriculum. Two programs, Radio Jove and Telescopes In Education have made important contributions in this field. Radio JOVE is an interactive, hands-on, educational activity for learning the scientific method through the medium of radio observations of Jupiter, the Sun, and the galactic radio background. Students build radio receivers from relatively inexpensive non-profit kits (about \\$125 plus shipping) and use them to record data, analyze the data, and share the results with others. Alternatively, for no cost, the students can record and analyze data from remote radio receivers connected to the web. The projects are useful adjuncts to activities in optical observing since students should recognize that we learn about the universe through more than just the optical spectrum. The projects are mini-electronics courses and also teach about charged particles and magnetic fields. The Radio JOVE web site (http://radiojove.gsfc.nasa.gov) should be consulted for further information. The NASA-sponsored Telescopes In Education (TIE) network (http://tie.jpl.nasa.gov) has been wildly successful in engaging the K-12 education community in real-time, hands-on, interactive astronomy activities. Hundreds of schools in the US, Australia, Canada, England, and Japan have participated in the TIE program, remotely controlling the 24-inch telescope at the Mount Wilson Observatory from their classrooms. In recent years, several (approximately 20 to date) other telescopes have been, or are in the process of being, outfitted for remote use as TIE affiliates. These telescopesare integrated seamlessly into one virtual observatory providing the services required to operate this facility, including a scheduling service, tools for data manipulation, an online proposal review environment, an online "Virtual TIE Student Ap J" for publication of results, and access to related educational materials provided by the TIE community.

Designing for scale: development of the ReMotion Knee for global emerging markets.

Hamner, Samuel R; Narayan, Vinesh G; Donaldson, Krista M

2013-09-01

Amputees living in developing countries have a profound need for affordable and reliable lower limb prosthetic devices. The World Health Organization estimates there are approximately 30 million amputees living in low-income countries, with up to 95% lacking access to prosthetic devices. Effective prosthetics can significantly affect the lives of these amputees by increasing opportunity for employment and providing improvements to long-term health and well-being. However, current solutions are inadequate: state-of-the-art solutions from the US and Europe are cost-prohibitive, while low-cost devices have been challenged by poor quality and/or unreliable performance, and have yet to achieve large scale impact. The introduction of new devices is hampered by the lack of a cohesive prosthetics industry in low-income areas; the current network of low-cost prosthetic clinics is informal and loosely organized with significant disparities in geography, patient volume and demographics, device procurement, clinical and logistical infrastructure, and funding. At D-Rev (Design Revolution) we are creating the ReMotion Knee, which is an affordable polycentric prosthetic knee joint that performs on par with devices in more industrialized regions, like the US and Europe. As of September 2012, over 4200 amputees have been fitted with the initial version of the ReMotion Knee through a partnership with the JaipurFoot Organization, with an 79% compliance rate after 2 years. We are currently scaling production of the ReMotion Knee using centralized manufacturing and distribution to serve the existing clinics in low-income countries and increase the availability of devices for amputees without access to appropriate care. At D-Rev, we develop products that target these customers through economically-sustainable models and provide a measurable impact in the lives of the world's amputees.

Since the 1970s, radar remote sensing techniques have evolved rapidly and are increasingly employed in all fields of earth sciences. Applications are manifold and still expanding due to the continuous development of new instruments and missions as well as the availability of very high-quality data. The trend worldwide is towards operational employment of the various algorithms and methods that have been developed. However, the utilization of operational services does not keep up yet with the rate of technical developments and the improvements in sensor technology. With the enhancing availability and variety of space borne Synthetic Aperture Radar (SAR) data and a growing number of analysis algorithms the need for a vital user community is increasing. Therefore the German Aerospace Center (DLR) together with the Friedrich-Schiller-University Jena (FSU) and the Technical University Munich (TUM) launched the education initiative SAR-EDU. The aim of the project is to facilitate access to expert knowledge in the scientific field of radar remote sensing. Within this effort a web portal will be created to provide seminar material on SAR basics, methods and applications to support both, lecturers and students. The overall intension of the project SAR-EDU is to provide seminar material for higher education in radar remote sensing covering the topic holistically from the very basics to the most advanced methods and applications that are available. The principles of processing and interpreting SAR data are going to be taught using test data sets and open-source as well as commercial software packages. The material that is provided by SAR-EDU will be accessible at no charge from a DLR web portal. The educational tool will have a modular structure, consisting of separate modules that broach the issue of a particular topic. The aim of the implementation of SAR-EDU as application-oriented radar remote sensing educational tool is to advocate the development and wider use of operational services on the base of pre-existing algorithms and sensors on the one hand, and to aid the extension of radar remote sensing techniques to a broader field of application on the other. SAR-EDU therefore combines the knowledge, expertise and experience of an excellent German consortium.

North Eastern Region (NER) of India comprising of eight states considered to be most unique and one of the most challenging regions to govern due to its unique physiographic condition, rich biodiversity, disaster prone and diverse socio-economic characteristics. Operational Remote Sensing services increased manifolds in the region with the establishment of North Eastern Space Applications Centre (NESAC) in the year 2000. Since inception, NESAC has been providing remote sensing services in generating inventory, planning and developmental activities, and management of natural resources, disasters and dissemination of information and services through geo-web services for NER. The operational remote sensing services provided by NESAC can be broadly divided into three categories viz. natural resource planning and developmental services, disaster risk reduction and early warning services and information dissemination through geo-portal services. As a apart of natural resources planning and developmental services NESAC supports the state forest departments in preparing the forest working plans by providing geospatial inputs covering entire NER, identifying the suitable culturable wastelands for cultivation of silkworm food plants, mapping of natural resources such as land use/land cover, wastelands, land degradation etc. on temporal basis. In the area of disaster risk reduction, NESAC has initiated operational services for early warning and post disaster assessment inputs for flood early warning system (FLEWS) using satellite remote sensing, numerical weather prediction, hydrological modeling etc.; forest fire alert system with actionable attribute information; Japanese Encephalitis Early Warning System (JEWS) based on mosquito vector abundance, pig population and historical disease intensity and agriculture drought monitoring for the region. The large volumes of geo-spatial databases generated as part of operational services are made available to the administrators and local government bodies for better management, preparing prospective planning, and sustainable use of available resources. The knowledge dissemination is being done through online web portals wherever the internet access is available and as well as offline space based information kiosks, where the internet access is not available or having limited bandwidth availability. This paper presents a systematic and comprehensive study on the remote sensing services operational in NER of India for natural resources management, disaster risk reduction and dissemination of information and services, in addition to outlining future areas and direction of space applications for the region.

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.

Geobrowser Enhanced Access of Real-Time Antarctic Data

2007-12-01

A proof of principle project was initiated in the Fall of 2006 to develop a system enabling remote field station and ship borne data, collected in near real-time to be discovered, visualised and acquired through a web accessible framework. The two principal enabling drivers for this system were the recent improvements in communications with remote field stations and ships and the advent of low cost, easily accessible geobrowser technology providing the ability to visualise multiple, sometimes physically disparate datasets within a common interface. Strongly spatial in nature the oceanographic datasets suggested the incorporation of geobrowser (Google Earth) technology into this framework. A number of scientific benefits were identified by the project, these include the overall enhancing of the value of many of the datasets through their real-time contribution to forecasting models, satellite ground truthing and calibration of autonomous instrumentation. Improved efficacy of fieldwork led to rapid discovery of problems and the ability to deal with them promptly. The ability to correct or improve experiment parameters and increase capability of routine collection of high-quality data. In the past it may have been over a year before data arrived back at HQ potentially unusable, definitely unrepeatable and significantly reducing or delaying scientific output. The geobrowser interface provides the platform from which the spatial data is discovered, for example ship tracks and aspects of the physical oceanography such as sea surface temperature can be directly visualized. Importantly, ancillary and auxiliary information and metadata can be linked to the cruise data in a straightforward and accessible manner; scientists in Cambridge using a geobrowser were able to access and visualize cruise data from the Southern ocean 20 minutes after collection.

Random Access Memories: A New Paradigm for Target Detection in High Resolution Aerial Remote Sensing Images.

PubMed

Zou, Zhengxia; Shi, Zhenwei

2018-03-01

We propose a new paradigm for target detection in high resolution aerial remote sensing images under small target priors. Previous remote sensing target detection methods frame the detection as learning of detection model + inference of class-label and bounding-box coordinates. Instead, we formulate it from a Bayesian view that at inference stage, the detection model is adaptively updated to maximize its posterior that is determined by both training and observation. We call this paradigm "random access memories (RAM)." In this paradigm, "Memories" can be interpreted as any model distribution learned from training data and "random access" means accessing memories and randomly adjusting the model at detection phase to obtain better adaptivity to any unseen distribution of test data. By leveraging some latest detection techniques e.g., deep Convolutional Neural Networks and multi-scale anchors, experimental results on a public remote sensing target detection data set show our method outperforms several other state of the art methods. We also introduce a new data set "LEarning, VIsion and Remote sensing laboratory (LEVIR)", which is one order of magnitude larger than other data sets of this field. LEVIR consists of a large set of Google Earth images, with over 22 k images and 10 k independently labeled targets. RAM gives noticeable upgrade of accuracy (an mean average precision improvement of 1% ~ 4%) of our baseline detectors with acceptable computational overhead.

Mobile computing technologies are increasingly becoming a valuable asset in healthcare information systems. The adoption of these technologies helps to assist in improving quality of care, increasing productivity and facilitating clinical decision support. They provide practitioners with ubiquitous access to patient records, being actually an important component in telemedicine and tele-work environments. We have developed Dicoogle Mobile, an Android application that provides remote access to distributed medical imaging data through a cloud relay service. Besides, this application has the capability to store and index local imaging data, so that they can also be searched and visualized. In this paper, we will describe Dicoogle Mobile concept as well the architecture of the whole system that makes it running.

Development of a national electronic interval cancer review for breast screening

Reviewing interval cancers and prior screening mammograms are a key measure to monitor screening performance. Radiological analysis of the imaging features in prior mammograms and retrospective classification are an important educational tool for readers to improve individual performance. The requirements of remote, collaborative image review sessions, such as those required to run a remote interval cancer review, are variable and demand a flexible and configurable software solution that is not currently available on commercial workstations. The wide range of requirements for both collection and remote review of interval cancers has precipitated the creation of extensible medical image viewers and accompanying systems. In order to allow remote viewing, an application has been designed to allow workstation-independent, PACS-less viewing and interaction with medical images in a remote, collaborative manner, providing centralised reporting and web-based feedback. A semi-automated process, which allows the centralisation of interval cancer cases, has been developed. This stand-alone, flexible image collection toolkit provides the extremely important function of bespoke, ad-hoc image collection at sites where there is no dedicated hardware. Web interfaces have been created which allow a national or regional administrator to organise, coordinate and administer interval cancer review sessions and deploy invites to session members to participate. The same interface allows feedback to be analysed and distributed. The eICR provides a uniform process for classifying interval cancers across the NHSBSP, which facilitates rapid access to a robust 'external' review for patients and their relatives seeking answers about why their cancer was 'missed'.

Individuals living in rural and remote settings face oral health problems and access-to-care barriers due to the shortage of oral health care providers in these areas, geographic remoteness, lack of appropriate infrastructure and lower socio-economic status. E-Oral Health technology could mitigate these barriers by providing the delivery of some aspects of health care and exchange of information across geographic distances. This review will systematically evaluate the literature on patient satisfaction with received E-Oral Health care in rural and remote communities. This systematic review will include interventional and observational studies in which E-Oral Health technology is used as an intervention in rural and remote communities of any country worldwide. Conventional oral health care will be used as a comparator when provided. Patient satisfaction with received E-Oral Health care will be considered as a primary outcome for this review. Cochrane Central Register of Controlled Trials, MEDLINE, EMBASE and Global Health will be searched using a comprehensive search strategy. Two review authors will independently screen results to identify potentially eligible studies and independently extract the data from the included studies. A third author will resolve any discrepancies between reviewers. Two independent researchers will assess the risk of bias and the Grading of Recommendations Assessment, Development, and Evaluation. The potential implications and benefits of E-Oral Health care can inform policymakers and health care professionals to take advantage of this technology to address health care challenges in these areas.

Two-year colleges and Tribal colleges are important centers for workforce education and training. A professional development program funded by the National Science Foundation's Advanced Technological Education Program, 2007-2011 and 2012-2015, is providing the resources needed by instructors at those colleges to develop courses and programs in remote sensing. The highly successful program, "Integrated Geospatial Education and Technology Training-Remote Sensing (iGETT-RS)" will complete its currently funded work in May 2015. 76 instructors of Geographic Information Systems (GIS) from all over the country will have been served. Each of them will have spent 18 months on the project, participating in two Summer Institutes at NASA and USGS and in monthly webinars on science and technology of remote sensing. iGETT-RS participants have created their own exercises and "concept modules" for the classroom, and many have created new courses and new programs across the country. As the external evaluator for iGETT-RS expressed it, the impact on project participants can "only be described as transformational." Viewers of this presentation will learn about the iGETT-RS project design and approach; successes, failures and lessons learned by the staff; and how to access the workshop materials and participant-authored classroom resources. Viewers will also learn about the Geospatial Technology Competency Model at the US Department of Labor, and about specifications for the Remote Sensing Model Course recently developed by the National Geospatial Technology Center to provide invaluable frameworks for faculty, students, administrators and employers.

The availability of increasingly large and diverse satellite remote sensing datasets provides both an opportunity and a challenge across broad Earth science research communities. On one hand, the extensive assortment of available data offer unprecedented opportunities to improve our understanding of Earth science and enable data use across a multitude of science disciplines. On the other hand, increasingly complex formats, data structures, and metadata can be an obstacle to data use for the broad user community that is interested in incorporating remote sensing Earth science data into their research. NASA's Land Processes Distributed Active Archive Center (LP DAAC) provides easy to use Python notebook tutorials for services such as accessing land remote sensing data from the LP DAAC Data Pool and interpreting data quality information from MODIS. We use examples to demonstrate the capabilities of the Application for Extracting and Exploring Analysis Ready Samples (AppEEARS), such as spatially and spectrally subsetting data, decoding valuable quality information, and exploring initial analysis results within the user interface. We also show data recipes for R and Python scripts that help users process ASTER L1T and ASTER Global Emissivity Datasets.

Transpiring purging access probe for particulate laden or hazardous environments

DOEpatents

VanOsdol, John G

2013-12-03

An access probe for remote-sensing access through a viewing port, viewing volume, and access port into a vessel. The physical boundary around the viewing volume is partially formed by a porous sleeve lying between the viewing volume and a fluid conduit. In a first mode of operation, a fluid supplied to the fluid conduit encounters the porous sleeve and flows through the porous material to maintain the viewing volume free of ash or other matter. When additional fluid force is needed to clear the viewing volume, the pressure of the fluid flow is increased sufficiently to slidably translate the porous sleeve, greatly increasing the flow into the viewing volume. The porous sleeve is returned to position by an actuating spring. The access probe thereby provides for alternate modes of operation based on the pressure of an actuating fluid.

Telescience Resource Kit (TReK) is a suite of application programs that enable geographically dispersed users to monitor scientific payloads aboard the International Space Station (ISS). TReK provides local ground support services that can simultaneously receive, process, record, playback, and display data from multiple sources. TReK also provides interfaces to use the remote services provided by the Payload Operations Integration Center which manages all ISS payloads. An application programming interface (API) allows for payload users to gain access to all data processed by TReK and allows payload-specific tools and programs to be built or integrated with TReK. Used in conjunction with other ISS-provided tools, TReK provides the ability to integrate payloads with the operational ground system early in the lifecycle. This reduces the potential for operational problems and provides "cradle-to-grave" end-to-end operations. TReK contains user guides and self-paced tutorials along with training applications to allow the user to become familiar with the system.

Satellite Remote Sensing of Harmful Algal Blooms (HABs) and a Potential Synthesized Framework

PubMed Central

Shen, Li; Xu, Huiping; Guo, Xulin

2012-01-01

Harmful algal blooms (HABs) are severe ecological disasters threatening aquatic systems throughout the World, which necessitate scientific efforts in detecting and monitoring them. Compared with traditional in situ point observations, satellite remote sensing is considered as a promising technique for studying HABs due to its advantages of large-scale, real-time, and long-term monitoring. The present review summarizes the suitability of current satellite data sources and different algorithms for detecting HABs. It also discusses the spatial scale issue of HABs. Based on the major problems identified from previous literature, including the unsystematic understanding of HABs, the insufficient incorporation of satellite remote sensing, and a lack of multiple oceanographic explanations of the mechanisms causing HABs, this review also attempts to provide a comprehensive understanding of the complicated mechanism of HABs impacted by multiple oceanographic factors. A potential synthesized framework can be established by combining multiple accessible satellite remote sensing approaches including visual interpretation, spectra analysis, parameters retrieval and spatial-temporal pattern analysis. This framework aims to lead to a systematic and comprehensive monitoring of HABs based on satellite remote sensing from multiple oceanographic perspectives. PMID:22969372

The Remote Glow Discharge Experiment (RGDX) is a DC discharge plasma with variable pressure, end-plate voltage and externally applied axial magnetic field. While the experiment is located at PPPL, a webcam displays the live video online. The parameters (voltage, magnetic field and pressure) can be controlled remotely in real-time by opening a URL which shows the streaming video, as well as a set of Labview controls. The RGDX is designed as an outreach tool that uses the attractive nature of a plasma in order to reach a wide audience and extend the presence of plasma physics and fusion around the world. In March 2014, the RGDX was made publically available and, as of early July, it has had approximately 3500 unique visits from 107 countries and almost all 50 US states. We present recent upgrades, including the ability to remotely control the distance between the electrodes. These changes give users the capability of measuring Paschen's Law remotely and provides a comprehensive introduction to plasma physics to those that do not have access to the necessary equipment.

Many telescopes are deployed in Antarctica as it offers excellent astronomical observation conditions. However, because Antarctica's environment is harsh to humans, remote operation of telescope is necessary for observation. Furthermore, communication to devices in Antarctica through satellite link with low bandwidth and high latency limits the effectiveness of remote observation. This paper introduces a web service framework for remote astronomical observation in Antarctica. The framework is based on Python Tornado. RTS2-HTTPD and REDIS are used as the access interface to the telescope control system in Antarctica. The web service provides real-time updates through WebSocket. To improve user experience and control effectiveness under the poor satellite link condition, an agent server is deployed in the mainland to synchronize the Antarctic server's data and send it to domestic users in China. The agent server will forward the request of domestic users to the Antarctic master server. The web service was deployed and tested on Bright Star Survey Telescope (BSST) in Antarctica. Results show that the service meets the demands of real-time, multiuser remote observation and domestic users have a better experience of remote operation.

Provider attitudes toward STARPAHC: a telemedicine project on the Papago reservation.

Space Technology Applied to Rural Papago Advanced Health Care (STARPAHC), is a large-scale telemedicine project, sponsored jointly by the Indian Health Service (IHS), NASA, and the Papago tribe, and in operation on the Papago Indian Reservation outside Tucson Arizona, for the past two years. STARPAHC uses a mobile health unit (MHU), staffed by non-M.D. providers and linked by two-way television, radio, and remote telemetry to an IHS hospital up to 100 miles away, to make medical care available in remote areas of the reservation. Over a two-year-period beginning in January, 1975, 47 individual providers, including 21 physicians, were interviewed, at five intervals, to determine their receptivity to and acceptance of telemedicine; because of staff turnover, not all providers were interviewed at each different interval. Data suggests that television equipment was considered costly and in some cases inconvenient to M.D. providers; it was not considered always essential for providers to be able to diagnose and treat patients. The major problems providers cited were the unreliability of equipment and the time required for television consultations. The major benefit cited was improved access to health care for a population not previously receiving such care near their homes. Non-M.D. providers considered the link they were provided to physicians via television and voice communications from remote areas to be a major benefit.

2012-01-01

The goal of cloud-based services is to provide easy, scalable access to computing resources and IT services. The healthcare industry requires a private cloud that adheres to government mandates designed to ensure privacy and security of patient data while enabling access by authorized users. Cloud-based computing in the imaging market has evolved from a service that provided cost effective disaster recovery for archived data to fully featured PACS and vendor neutral archiving services that can address the needs of healthcare providers of all sizes. Healthcare providers worldwide are now using the cloud to distribute images to remote radiologists while supporting advanced reading tools, deliver radiology reports and imaging studies to referring physicians, and provide redundant data storage. Vendor managed cloud services eliminate large capital investments in equipment and maintenance, as well as staffing for the data center--creating a reduction in total cost of ownership for the healthcare provider.

With the rapid developments of Internet technologies, remote access and control via Internet is becoming a reality. A realization of the web-based laboratory (the W-LAB) was presented. The main target of the W-LAB was to allow users to easily access and conduct experiments via the Internet. While realizing the remote communication, a system, which adopted the double client-server architecture, was introduced. It ensures the system better security and higher functionality. The experimental environment implemented in the W-Lab was integrated by both virtual lab and remote lab. The embedded technology in the W-LAB system as an economical and efficient way to build the distributed infrastructural network was introduced. Furthermore, by introducing the user authentication mechanism in the system, it effectively secures the remote communication.

Development of a Remote Accessibility Assessment System through three-dimensional reconstruction technology.

PubMed

Kim, Jong Bae; Brienza, David M

2006-01-01

A Remote Accessibility Assessment System (RAAS) that uses three-dimensional (3-D) reconstruction technology is being developed; it enables clinicians to assess the wheelchair accessibility of users' built environments from a remote location. The RAAS uses commercial software to construct 3-D virtualized environments from photographs. We developed custom screening algorithms and instruments for analyzing accessibility. Characteristics of the camera and 3-D reconstruction software chosen for the system significantly affect its overall reliability. In this study, we performed an accuracy assessment to verify that commercial hardware and software can construct accurate 3-D models by analyzing the accuracy of dimensional measurements in a virtual environment and a comparison of dimensional measurements from 3-D models created with four cameras/settings. Based on these two analyses, we were able to specify a consumer-grade digital camera and PhotoModeler (EOS Systems, Inc, Vancouver, Canada) software for this system. Finally, we performed a feasibility analysis of the system in an actual environment to evaluate its ability to assess the accessibility of a wheelchair user's typical built environment. The field test resulted in an accurate accessibility assessment and thus validated our system.

High-quality remote interactive imaging in the operating theatre

2009-02-01

We present a high-quality display system that enables the remote access within an operating theatre of high-end medical imaging and surgical planning software. Currently, surgeons often use printouts from such software for reference during surgery; our system enables surgeons to access and review patient data in a sterile environment, viewing real-time renderings of MRI & CT data as required. Once calibrated, our system displays shades of grey in Operating Room lighting conditions (removing any gamma correction artefacts). Our system does not require any expensive display hardware, is unobtrusive to the remote workstation and works with any application without requiring additional software licenses. To extend the native 256 levels of grey supported by a standard LCD monitor, we have used the concept of "PseudoGrey" where slightly off-white shades of grey are used to extend the intensity range from 256 to 1,785 shades of grey. Remote access is facilitated by a customized version of UltraVNC, which corrects remote shades of grey for display in the Operating Room. The system is successfully deployed at Morriston Hospital, Swansea, UK, and is in daily use during Maxillofacial surgery. More formal user trials and quantitative assessments are being planned for the future.

The presentation describes the recently awarded ACCESS project to provide data management of NASA remote sensing data for the Northern Eurasia Earth Science Partnership Initiative (NEESPI). The project targets integration of remote sensing data from MODIS, and other NASA instruments on board US-satellites (with potential expansion to data from non-US satellites), customized data products from climatology data sets (e.g., ISCCP, ISLSCP) and model data (e.g., NCEP/NCAR) into a single, well-architected data management system. It will utilize two existing components developed by the Goddard Earth Sciences Data & Information Services Center (GES DISC) at the NASA Goddard Space Flight Center: (1) online archiving and distribution system, that allows collection, processing and ingest of data from various sources into the online archive, and (2) user-friendly intelligent web-based online visualization and analysis system, also known as Giovanni. The former includes various kinds of data preparation for seamless interoperability between measurements by different instruments. The latter provides convenient access to various geophysical parameters measured in the Northern Eurasia region without any need to learn complicated remote sensing data formats, or retrieve and process large volumes of NASA data. Initial implementation of this data management system will concentrate on atmospheric data and surface data aggregated to coarse resolution to support collaborative environment and climate change studies and modeling, while at later stages, data from NASA and non-NASA satellites at higher resolution will be integrated into the system.

Steep, hardly accessible cliffs of rhyolite tuff in NE Hungary are prone to rockfalls, endangering visitors of a castle. Remote sensing techniques were employed to obtain data on terrain morphology and to provide slope geometry for assessing the stability of these rock walls. A RPAS (Remotely Piloted Aircraft System) was used to collect images which were processed by Pix4D mapper (structure from motion technology) to generate a point cloud and mesh. The georeferencing was made by Global Navigation Satellite System (GNSS) with the use of seven ground control points. The obtained digital surface model (DSM) was processed (vegetation removal) and the derived digital terrain model (DTM) allowed cross sections to be drawn and a joint system to be detected. Joint and discontinuity system was also verified by field measurements. On-site tests as well as laboratory tests provided additional engineering geological data for slope modelling. Stability of cliffs was assessed by 2-D FEM (finite element method). Global analyses of cross sections show that weak intercalating tuff layers may serve as potential slip surfaces. However, at present the greatest hazard is related to planar failure along ENE-WSW joints and to wedge failure. The paper demonstrates that RPAS is a rapid and useful tool for generating a reliable terrain model of hardly accessible cliff faces. It also emphasizes the efficiency of RPAS in rockfall hazard assessment in comparison with other remote sensing techniques such as terrestrial laser scanning (TLS).

Estimates of Leaf Relative Water Content from Optical Polarization Measurements

Remotely sensing the water status of plant canopies remains a long term goal of remote sensing research. Existing approaches to remotely sensing canopy water status, such as the Crop Water Stress Index (CWSI) and the Equivalent Water Thickness (EWT), have limitations. The CWSI, based upon remotely sensing canopy radiant temperature in the thermal infrared spectral region, does not work well in humid regions, requires estimates of the vapor pressure deficit near the canopy during the remote sensing over-flight and, once stomata close, provides little information regarding the canopy water status. The EWT is based upon the physics of water-light interaction in the 900-2000nm spectral region, not plant physiology. Our goal, development of a remote sensing technique for estimating plant water status based upon measurements in the VIS/NIR spectral region, would potentially provide remote sensing access to plant dehydration physiology - to the cellular photochemistry and structural changes associated with water deficits in leaves. In this research, we used optical, crossed polarization filters to measure the VIS/NIR light reflected from the leaf interior, R, as well as the leaf transmittance, T, for 78 corn (Zea mays) and soybean (Glycine max) leaves having relative water contents (RWC) between 0.60 and 0.98. Our results show that as RWC decreases R increases while T decreases. Our results tie R and T changes in the VIS/NIR to leaf physiological changes - linking the light scattered out of the drying leaf interior to its relative water content and to changes in leaf cellular structure and pigments. Our results suggest remotely sensing the physiological water status of a single leaf - and perhaps of a plant canopy - might be possible in the future.

2002-01-01

The Virtual Mission Operations Center - Collaborative Environment (VMOC-CE) intent is to have a central access point for all the resources used in a collaborative mission operations environment to assist mission operators in communicating on-site and off-site in the investigation and resolution of anomalies. It is a framework that as a minimum incorporates online chat, realtime file sharing and remote application sharing components in one central location. The use of a collaborative environment in mission operations opens up the possibilities for a central framework for other project members to access and interact with mission operations staff remotely. The goal of the Virtual Mission Operations Center (VMOC) Project is to identify, develop, and infuse technology to enable mission control by on-call personnel in geographically dispersed locations. In order to achieve this goal, the following capabilities are needed: Autonomous mission control systems Automated systems to contact on-call personnel Synthesis and presentation of mission control status and history information Desktop tools for data and situation analysis Secure mechanism for remote collaboration commanding Collaborative environment for remote cooperative work The VMOC-CE is a collaborative environment that facilitates remote cooperative work. It is an application instance of the Virtual System Design Environment (VSDE), developed by NASA Goddard Space Flight Center's (GSFC) Systems Engineering Services & Advanced Concepts (SESAC) Branch. The VSDE is a web-based portal that includes a knowledge repository and collaborative environment to serve science and engineering teams in product development. It is a "one stop shop" for product design, providing users real-time access to product development data, engineering and management tools, and relevant design specifications and resources through the Internet. The initial focus of the VSDE has been to serve teams working in the early portion of the system/product lifecycle - concept development, proposal preparation, and formulation. The VMOC-CE expands the application of the VSDE into the operations portion of the system lifecycle. It will enable meaningful and real-time collaboration regardless of the geographical distribution of project team members. Team members will be able to interact in satellite operations, specifically for resolving anomalies, through access to a desktop computer and the Internet. Mission Operations Management will be able to participate and monitor up to the minute status of anomalies or other mission operations issues. In this paper we present the VMOC-CE project, system capabilities, and technologies.

To understand and predict Earth-surface dynamics, scientists often rely on access to the latest remote sensing data. Over the past several decades, considerable progress has been made in the development of specialized Earth observation sensors for measuring a wide range of processes and features. Comparatively little progress has been made, however, in the development of new platforms upon which these sensors can be deployed. Conventional platforms are still almost exclusively restricted to piloted aircraft and satellites. For many Earth science research questions and applications these platforms do not yet have the resolution or operational flexibility to provide answers affordably. The most effective remote sensing data match the spatiotemporal scale of the process or feature of interest. An emerging technology comprising unmanned aircraft systems (UAS), also known as unmanned aerial vehicles (UAV), is poised to offer a viable alternative to conventional platforms for acquiring high-resolution remote sensing data with increased operational flexibility, lower cost, and greater versatility (Figure 1).

The aim of this study was to describe the reorientation of a remote primary health-care service, in the Kimberley region of Australia, its impact on access to services and the factors instrumental in bringing about change. A unique community-initiated health service partnership was developed between a community-controlled Aboriginal health organisation, a government hospital and a population health unit, in order to overcome the challenges of delivering primary health care to a dispersed, highly disadvantaged Aboriginal population in a very remote area. The shared goals and clear delineation of responsibilities achieved through the partnership reoriented an essentially acute hospital-based service to a prevention-focussed comprehensive primary health-care service, with a focus on systematic screening for chronic disease, interdisciplinary follow up, health promotion, community advocacy and primary prevention. This formal partnership enabled the primary health-care service to meet the major challenges of providing a sustainable, prevention-focussed service in a very remote and socially disadvantaged area.

An object-based storage model for distributed remote sensing images

2006-10-01

It is very difficult to design an integrated storage solution for distributed remote sensing images to offer high performance network storage services and secure data sharing across platforms using current network storage models such as direct attached storage, network attached storage and storage area network. Object-based storage, as new generation network storage technology emerged recently, separates the data path, the control path and the management path, which solves the bottleneck problem of metadata existed in traditional storage models, and has the characteristics of parallel data access, data sharing across platforms, intelligence of storage devices and security of data access. We use the object-based storage in the storage management of remote sensing images to construct an object-based storage model for distributed remote sensing images. In the storage model, remote sensing images are organized as remote sensing objects stored in the object-based storage devices. According to the storage model, we present the architecture of a distributed remote sensing images application system based on object-based storage, and give some test results about the write performance comparison of traditional network storage model and object-based storage model.

The healthcare researchers', academics' and practitioners' interest concerning the development of Healthcare Information Systems has been on a steady rise for the last decades. Fueling this steady rise has been the healthcare professional need of quality information, in every healthcare provision incident, whenever and wherever this incident may take place. In order to address this need a truly mobile health care system is required, one that will be able to provide a healthcare provider with accurate patient-related information regardless of the time and place that healthcare is provided. In order to fulfill this role the present study proposes the architecture for a Healthcare Smartcard system, which provides authenticated healthcare professionals with remote mobile access to a Patient's Healthcare Record, through their Smartphone. Furthermore the research proceeds to develop a working prototype system.

Apparatus for remote handling of materials are described. A closed housing is provided with first and second containers and first and second reservoirs for holding materials to be mixed. The materials are transferable from the reservoirs to the first container where they are mixed. The mixed materials are then conveyed from the first container to the second container preferably by dumping the mixed materials into a funnel positioned over the second container. The second container is then moved to a second position for analysis of the mixed materials. For example, the materials may be ignited and the flame analyzed. Access, such as a sight port, is provided in the housing at the analysis position. The device provides a simple and inexpensive apparatus for safely mixing a pyrophoric material and an oxidizer which together form a thermite type mixture that burns to produce a large quantity of heat and light.

2015-06-01

A perennial issue for rural and remote communities in Canada and in other parts of the world is access to a healthcare delivery system including healthcare personnel to provide care to their residents. In total, 18% of Canadians live in rural locations but by proportion have fewer healthcare providers compared with urban settings. Relying on a recently completed documentary analysis of published reports and grey literature on rural and remote nursing practice from Canada and around the world, we recognize that recruitment and retention will be a recurring issue. However, a variety of programs and initiatives have been developed to address this age-old problem. A discussion is provided about educational opportunities, financial incentives and enhanced infrastructure that have been developed to address recruitment and retention challenges. Ongoing evaluations of each of these areas are necessary but require cooperation across provincial and national settings. Copyright © 2015 Longwoods Publishing.

2003-05-01

The Virtual Solar Observatory (VSO) project has implemented a time interval search for all four participating data archives. The back-end query services are implemented as web services, and are accessible via SOAP. SOAP (Simple Object Access Protocol) defines an RPC (Remote Procedure Call) mechanism that employs HTTP as its transport and encodes the client-server interactions (request and response messages) in XML (eXtensible Markup Language) documents. In addition to its core function of identifying relevant datasets in the local archive, the SOAP server at each data provider acts as a "wrapper" that maps descriptions in an abstract data model to those in the provider-specific data model, and vice versa. It is in this way that VSO integrates heterogeneous data services and allows access to them using a common interface. Our experience with SOAP has been fruitful. It has proven to be a better alternative to traditional web access methods, namely POST and GET, because of its flexibility and interoperability.

Creating Web-Based Scientific Applications Using Java Servlets

NASA Technical Reports Server (NTRS)

Palmer, Grant; Arnold, James O. (Technical Monitor)

2001-01-01

There are many advantages to developing web-based scientific applications. Any number of people can access the application concurrently. The application can be accessed from a remote location. The application becomes essentially platform-independent because it can be run from any machine that has internet access and can run a web browser. Maintenance and upgrades to the application are simplified since only one copy of the application exists in a centralized location. This paper details the creation of web-based applications using Java servlets. Java is a powerful, versatile programming language that is well suited to developing web-based programs. A Java servlet provides the interface between the central server and the remote client machines. The servlet accepts input data from the client, runs the application on the server, and sends the output back to the client machine. The type of servlet that supports the HTTP protocol will be discussed in depth. Among the topics the paper will discuss are how to write an http servlet, how the servlet can run applications written in Java and other languages, and how to set up a Java web server. The entire process will be demonstrated by building a web-based application to compute stagnation point heat transfer.

Use of telemedicine in disaster and remote places

One of the methods, especially those living in remote areas or have crashed and does not have access to specialists is telemedicine. Telemedicine describes the use of medical information exchanged from one site to another via electronic communications to improve patients’ health status and care. Travel and wait times between the initial consultations with the patient's own general practitioner and referral to specialist can be reduced and specialists have successfully provided remote triage and treatment consults of victims via the robot. The robot proved to be a useful means to extend resources and provide expert consulting if specialists were unable to physically be at the site. In fact, the telemedicine system is providing health care services for individuals who are not available because of geographical and environmental conditions. The aim of this study was to identify telemedicine applications in disaster, and proposed use of this technology in areas where the shortage of specialists in remote areas in disasters. This study was un-systematic (narrative) review. The literature was searched for using of telemedicine in disaster and remote places with the help of libraries, conference proceedings, data bank, and also search engines available at Google, Google scholar. In our searches, we employed the following keywords and their combinations: telemedicine, remote place, earthquake, disaster, war, and telecommunication in the searching areas of title, keyword, abstract, and full text. In this study, more than 85 articles and reports were collected and 26 of them were selected based on their relevancy. This literature review helps define the concept of “components and usages of the Telemedicine in disaster” as the new technology in the present age. PMID:25013819

The U.S. Agency for International Development (USAID)'s Famine Early Warning System Network (FEWS NET) provides monitoring and early warning support to decision makers responsible for responding to food insecurity emergencies on three continents. FEWS NET uses satellite remote sensing and ground observations of rainfall and vegetation in order to provide information on drought, floods, and other extreme weather events to decision makers. Previous research has presented results from a professional review questionnaire with FEWS NET expert end-users whose focus was to elicit Earth observation requirements. The review provided FEWS NET operational requirements and assessed the usefulness of additional remote sensing data. We analyzed 1342 food security update reports from FEWS NET. The reports consider the biophysical, socioeconomic, and contextual influences on the food security in 17 countries in Africa from 2000 to 2009. The objective was to evaluate the use of remote sensing information in comparison with other important factors in the evaluation of food security crises. The results show that all 17 countries use rainfall information, agricultural production statistics, food prices, and food access parameters in their analysis of food security problems. The reports display large-scale patterns that are strongly related to history of the FEWS NET program in each country. We found that rainfall data were used 84% of the time, remote sensing of vegetation 28% of the time, and gridded crop models 10% of the time, reflecting the length of use of each product in the regions. More investment is needed in training personnel on remote sensing products to improve use of data products throughout the FEWS NET system.

The Earth Resources Observation Systems (EROS) Data Center (EDO, administered by the U.S. Geological Survey, U.S. Department of the Interior, provides remotely sensed data to the user community and offers a variety of professional services to further the understanding and use of remote sensing technology. EDC reproduces and sells photographic and electronic copies of satellite images of areas throughout the world. Other products include aerial photographs collected by 16 organizations, including the U.S. Geological Survey and the National Aeronautics and Space Administration. Primary users of the remotely sensed data are Federal, State, and municipal government agencies, universities, foreign nations, and private industries. The professional services available at EDC are primarily directed at integrating satellite and aircraft remote sensing technology into the programs of the Department of the Interior and its cooperators. This is accomplished through formal training workshops, user assistance, cooperative demonstration projects, and access to equipment and capabilities in an advanced data analysis laboratory. In addition, other Federal agencies, State and local governments, universities, and the general public can get assistance from the EDC Staff. Since 1973, EDC has contributed to the accelerating growth in development and operational use of remotely sensed data for land resource problems through its role as educator and by conducting basic and applied remote sensing applications research. As remote sensing technology continues to evolve, EDC will continue to respond to the increasing demand for timely information on remote sensing applications. Questions most often asked about EDC's research and training programs include: Who may attend an EDC remote sensing training course? Specifically, what is taught? Who may cooperate with EDC on remote sensing projects? Are interpretation services provided on a service basis? This report attempts to define the goals and objectives of and policies on the following EDC services: Training Program.User Assistance.Data Analysis Laboratory.Cooperative Demonstration Projects.Research Projects.

Horizontal equity and efficiency at primary health care facilities in rural Afghanistan: a seemingly unrelated regression approach.

Johns, Benjamin; Steinhardt, Laura; Walker, Damian G; Peters, David H; Bishai, David

2013-07-01

Producing services efficiently and equitably are important goals for health systems. Many countries pursue horizontal equity - providing people with the same illnesses equal access to health services - by locating facilities in remote areas. Staff are often paid incentives to work at such facilities. However, there is little evidence on how many fewer people are treated at remote facilities than facilities in more densely settled areas. This research explores if there is an association between the efficiency of health centers in Afghanistan and the remoteness of their location. Survey teams collected data on facility level inputs and outputs at a stratified random sample of 579 health centers in 2005. Quality of care was measured by observing staff interact with patients and determining if staff completed a set of normative patient care tasks. We used seemingly unrelated regression to determine if facilities in remote areas have fewer outpatient visits than other rural facilities. In this analysis, one equation compares the number of outpatient visits to facility inputs, while another compares quality of care to determinants of quality. The results indicate remote facilities have about 13% fewer outpatient visits than non-remote facilities, holding inputs constant. Our analysis suggests that facilities in remote areas are realizing horizontal equity since their clients are receiving comparable quality of care to those at non-remote facilities. However, we find the average labor cost for a visit at a remote facility is $1.44, but only $0.97 at other rural facilities, indicating that a visit in a remote facility would have to be 'worth' 1.49 times a visit at a rural facility for there to be no equity - efficiency trade-off. In determining where to build or staff health centers, this loss of efficiency may be offset by progress toward a social policy objective of providing services to disadvantaged rural populations.

Space medicine innovation and telehealth concept implementation for medical care during exploration-class missions

NASA Astrophysics Data System (ADS)

Martin, Annie; Sullivan, Patrick; Beaudry, Catherine; Kuyumjian, Raffi; Comtois, Jean-Marc

2012-12-01

Medical care on the International Space Station (ISS) is provided using real-time communication with limited medical data transmission. In the occurrence of an off-nominal medical event, the medical care paradigm employed is 'stabilization and transportation', involving real-time management from ground and immediate return to Earth in the event that the medical contingency could not be resolved in due time in space. In preparation for future missions beyond Low-Earth orbit (LEO), medical concepts of operations are being developed to ensure adequate support for the new mission profiles: increased distance, duration and communication delays, as well as impossibility of emergency returns and limitations in terms of medical equipment availability. The current ISS paradigm of medical care would no longer be adequate due to these new constraints. The Operational Space Medicine group at the Canadian Space Agency (CSA) is looking towards synergies between terrestrial and space medicine concepts for the delivery of medical care to deal with the new challenges of human space exploration as well as to provide benefits to the Canadian population. Remote and rural communities on Earth are, in fact, facing similar problems such as isolation, remoteness to tertiary care centers, resource scarcity, difficult (and expensive) emergency transfers, limited access to physicians and specialists and limited training of medical and nursing staff. There are a number of researchers and organizations, outside the space communities, working in the area of telehealth. They are designing and implementing terrestrial telehealth programs using real-time and store-and-forward techniques to provide isolated populations access to medical care. The cross-fertilization of space-Earth research could provide support for increased spin-off and spin-in effects and stimulate telehealth and space medicine innovations to engage in the new era of human space exploration. This paper will discuss the benefits of space-Earth research projects for the advancement of both terrestrial and space medicine and will use examples of operational space medicine projects conducted at the CSA in areas such as remote training, tele-mentoring and remote control of an ultrasound.

1997-01-01

This paper details two projects that use the World Wide Web (WWW) for dissemination of curricula that focus on remote sensing. 1) Presenting grade-school students with the concepts used in remote sensing involves educating the teacher and then providing the teacher with lesson plans. In a NASA-sponsored project designed to introduce students in grades 4 through 12 to some of the ideas and terminology used in remote sensing, teachers from local grade schools and middle schools were recruited to write lessons about remote sensing concepts they could use in their classrooms. Twenty-two lessons were produced and placed in seven modules that include: the electromagnetic spectrum, two- and three-dimensional perception, maps and topography, scale, remote sensing, biotic and abiotic concepts, and landscape chi rise. Each lesson includes a section that evaluates what students have learned by doing the exercise. The lessons, instead of being published in a workbook and distributed to a limited number of teachers, have been placed on a WWW server, enabling much broader access to the package. This arrangement also allows for the lessons to be modified after feedback from teachers accessing the package. 2) Two-year colleges serve to teach trade skills, prepare students for enrollment in senior institutions of learning, and more and more, retrain students who have college degrees in new technologies and skills. A NASA-sponsored curriculum development project is producing a curriculum using remote sensing analysis an Earth science applications. The project has three major goals. First, it will implement the use of remote sensing data in a broad range of community college courses. Second, it will create curriculum modules and classes that are transportable to other community colleges. Third, the project will be an ongoing source of data and curricular materials to other community colleges. The curriculum will have these course pathways to a certificate; a) a Science emphasis, b) an Arts and Letters emphasis, and c) a Computer Science emphasis Each pathway includes course work in remote sensing, geographical information systems (GIS), computer science, Earth science, software and technology utilization, and communication. Distribution of products from this project to other two-year colleges will be accomplished using the WWW.

A Sample Data Publication: Interactive Access, Analysis and Display of Remotely Stored Datasets From Hurricane Charley

NASA Astrophysics Data System (ADS)

Weber, J.; Domenico, B.

2004-12-01

This paper is an example of what we call data interactive publications. With a properly configured workstation, the readers can click on "hotspots" in the document that launches an interactive analysis tool called the Unidata Integrated Data Viewer (IDV). The IDV will enable the readers to access, analyze and display datasets on remote servers as well as documents describing them. Beyond the parameters and datasets initially configured into the paper, the analysis tool will have access to all the other dataset parameters as well as to a host of other datasets on remote servers. These data interactive publications are built on top of several data delivery, access, discovery, and visualization tools developed by Unidata and its partner organizations. For purposes of illustrating this integrative technology, we will use data from the event of Hurricane Charley over Florida from August 13-15, 2004. This event illustrates how components of this process fit together. The Local Data Manager (LDM), Open-source Project for a Network Data Access Protocol (OPeNDAP) and Abstract Data Distribution Environment (ADDE) services, Thematic Realtime Environmental Distributed Data Service (THREDDS) cataloging services, and the IDV are highlighted in this example of a publication with embedded pointers for accessing and interacting with remote datasets. An important objective of this paper is to illustrate how these integrated technologies foster the creation of documents that allow the reader to learn the scientific concepts by direct interaction with illustrative datasets, and help build a framework for integrated Earth System science.

Access to mental health care in deaf communities is limited by cultural considerations, availability of translators, and technological considerations. Telepsychiatry can mitigate the deaf community's lack of access to care by allowing for deaf individuals in remote communities access to care with facilities that cater to their needs. Community Behavioral Health, Arundel Lodge, and Gallaudet University worked in conjunction to test three hypotheses: 1.Telepsychiatry will be as effective as traditional face-to-face psychotherapy with deaf adults who have chronic mental illness.2.Patients living in remote locations will report an improvement in accessibility to mental health services.3.Patients who receive telepsychiatry will report a comparable level of satisfaction of services to those receiving traditional services. The patient sample consisted of 24 participants, 13 women, 11 men. Telepsychiatry sessions were scheduled based on each patient's individual treatment plan against a control group who saw their providers face to face. The telepsychiatry and in-person groups were slightly different at baseline. Analysis of the data revealed no significant difference in coping abilities and psychiatric symptoms between those receiving face-to-face psychotherapy and those receiving telepsychiatry. The quality and outcome of care was equal to in-person for the telepsychiatry in deaf patients. Since telepsychiatry does not compromise the quality of care, it is a good means of reaching out to members of the deaf community that cannot readily access mental health resources that meet their needs.

Redefining nondiscriminatory access to remote sensing imagery and its impact on global transparency

Global transparency is founded on the Open Skies philosophy and its precept of non-discriminatory access. Global transparency implies that anyone can have anytime, anyplace access to a wide-array of remotely sensed imagery. The custom of non-discriminatory access requires that datasets of interest must be affordable, usable, and obtainable in a timely fashion devoid of political, economic or technical obstacles. Thus, an assessment of the correlation between the availability of satellite imagery and changes in governmental policies, pricing fluctuations of data, and advances in technology is critical to assessing the viability of global transparency. The Open Skies philosophy was originally proposed at the 1955 Geneva Summit to advocate mutually beneficial aerial reconnaissance missions over the USSR and the US as a verification tool for arms control and non-proliferation agreements. However, due to Cold War tensions, this philosophy and the custom of non-discriminatory were not widely adopted in the civilian remote sensing community until the commissioning of the Landsat Program in 1972. Since this time, commercial high-resolution satellites have drastically changed the circumstances on which the fundamental tenets of this philosophy are based. Since the successful launch of the first of this satellite class, the IKONOS satellite, high-resolution imagery is now available to non-US governments and an unlimited set of non-state actors. As more advanced capabilities are added to the growing assortment of remote sensing satellites, the reality of global transparency will rapidly evolve. This assessment includes an overview of historical precedents and a brief explanation of relevant US policy decisions that define non-discriminatory access with respect to US government and US based corporate assets. It also presents the dynamics of the political, economic, and technical barriers that may dictate or influence the remote sensing community's access to satellite data. In conclusion, this analysis considers strategies for balancing the dual-use nature of hyperspectral and high-resolution satellite imagery and discusses the potential impact of these policies on gloal transparency.

NASA Astrophysics Data System (ADS)

Driscoll, Brandon; Jaffray, David; Coolens, Catherine

2014-03-01

Purpose: To provide clinicians & researchers participating in multi-centre clinical trials with a central repository for large volume dynamic imaging data as well as a set of tools for providing end-to-end testing and image analysis standards of practice. Methods: There are three main pieces to the data archiving and analysis system; the PACS server, the data analysis computer(s) and the high-speed networks that connect them. Each clinical trial is anonymized using a customizable anonymizer and is stored on a PACS only accessible by AE title access control. The remote analysis station consists of a single virtual machine per trial running on a powerful PC supporting multiple simultaneous instances. Imaging data management and analysis is performed within ClearCanvas Workstation® using custom designed plug-ins for kinetic modelling (The DCE-Tool®), quality assurance (The DCE-QA Tool) and RECIST. Results: A framework has been set up currently serving seven clinical trials spanning five hospitals with three more trials to be added over the next six months. After initial rapid image transfer (+ 2 MB/s), all data analysis is done server side making it robust and rapid. This has provided the ability to perform computationally expensive operations such as voxel-wise kinetic modelling on very large data archives (+20 GB/50k images/patient) remotely with minimal end-user hardware. Conclusions: This system is currently in its proof of concept stage but has been used successfully to send and analyze data from remote hospitals. Next steps will involve scaling up the system with a more powerful PACS and multiple high powered analysis machines as well as adding real-time review capabilities.

Wiedenbeck, M.; Schäfer, L.; Klump, J.; Galkin, A.

2013-12-01

Overview: This poster describes the development of a Virtual Research Environment for the Secondary Ion Mass Spectrometer (SIMS) at GFZ Potsdam. Background: Secondary Ion Mass Spectrometers (SIMS) are extremely sensitive instruments for analyzing the surfaces of solid and thin film samples. These instruments are rare, expensive and experienced operators are very highly sought after. As such, measurement time is a precious commodity, until now only accessible to small numbers of researchers. The challenge: The Virtual SIMS Project aims to set up a Virtual Research Environment for the operation of the CAMECA IMS 1280-HR instrument at the GFZ Potsdam. The objective of the VRE is to provide SIMS access not only to researchers locally present in Potsdam but also to scientists working with SIMS cooperation partners in e.g., South Africa, Brazil or India. The requirements: The system should address the complete spectrum of laboratory procedures - from online application for measurement time, to remote access for data acquisition to data archiving for the subsequent publication and for future reuse. The approach: The targeted Virtual SIMS Environment will consist of a: 1. Web Server running the Virtual SIMS website providing general information about the project, lab access proposal forms and calendar for the timing of project related tasks. 2. LIMS Server, responsible for scheduling procedures, data management and, if applicable, accounting and billing. 3. Remote SIMS Tool, devoted to the operation of the experiment within a remote control environment. 4. Publishing System, which supports the publication of results in cooperation with the GFZ Library services. 5. Training Simulator, which offers the opportunity to rehearse experiments and to prepare for possible events such as a power outages or interruptions to broadband services. First results: The SIMS Virtual Research Environment will be mainly based on open source software, the only exception being the CAMECA IMS 1280-HR SIMS operating under LabView. The Publishing System will be based on eSciDoc, which is already successfully used by the GFZ scientific library. For the LIMS Server we are currently testing various options. The challenge, however, is the successful integration of all the various components and, where necessary, the definition of useful interfaces between the modules.

Cloud radio access networks (C-RAN) separates baseband units (BBU) of conventional base station to a centralized pool which connects remote radio heads (RRH) through mobile fronthaul. Mobile fronthaul is a new network segment of C-RAN, it is designed to transport digital sampling data between BBU and RRH. Optical transport networks that provide large bandwidth and low latency is a promising fronthaul solution. In this paper, we discuss several optical transport networks which are candidates for mobile fronthaul, analyze their performances including the number of used wavelength, round-trip latency and wavelength utilization.

Technology and the future of medical equipment maintenance.

PubMed

Wear, J O

1999-05-01

Maintenance of medical equipment has been changing rapidly in the past few years. It is changing more rapidly in developed countries, but changes are also occurring in developing countries. Some of the changes may permit improved maintenance on the higher technology equipment in developing countries, since they do not require onsite expertise. Technology has had an increasing impact on the development of medical equipment with the increased use of microprocessors and computers. With miniaturization from space technology and electronic chip design, powerful microprocessors and computers have been built into medical equipment. The improvement in manufacturing technology has increased the quality of parts and therefore the medical equipment. This has resulted in increased mean time between failures and reduced maintenance needs. This has made equipment more reliable in remote areas and developing countries. The built-in computers and advances in software design have brought about self-diagnostics in medical equipment. The technicians now have a strong tool to be used in maintenance. One problem in this area is getting access to the self-diagnostics. Some manufacturers will not readily provide this access to the owner of the equipment. Advances in telecommunications in conjunction with self-diagnostics make available remote diagnosis and repair. Since components can no longer be repaired, a remote repair technician can instruct an operator or an on-site repairman on board replacement. In case of software problems, the remote repair technician may perform the repairs over the telephone. It is possible for the equipment to be monitored remotely by modern without interfering with the operation of the equipment. These changes in technology require the training of biomedical engineering technicians (BMETs) to change. They must have training in computers and telecommunications. Some of this training can be done with telecommunications and computers.

Dementia is five-fold more prevalent among Aboriginal than non-Aboriginal Australians. Despite this, the quality of care available to people living with dementia in remote Aboriginal communities is poor. The objective of this study was to determine ways to overcome factors affecting the successful delivery of services to Aboriginal people with dementia living in remote communities, and to their families and communities. This qualitative research took place in the Kimberley Region of Western Australia. Data collection occurred in three stages: (1) interviews with service providers to identify the services available; (2) interviews with the caregivers of Aboriginal people living with dementia and community-based care workers; and (3) focus groups with community representatives and community care staff. Each stage was concluded when no new themes emerged. At each stage the transcribed information was analysed and joint interpretation identified common themes. In total, 42 service providers, 31 caregivers and community-based care workers were interviewed and 3 focus groups were conducted. Obstacles to accessing quality care were mentioned and recommendations on ways to improve care were made. The key themes that emerged were caregiver role, perspectives of dementia, community and culturally-appropriate care, workforce, education and training, issues affecting remote communities and service issues. Detailed information on how each theme affects the successful delivery of dementia care is provided. These research findings indicate that people living with dementia and their caregivers in remote Aboriginal communities are struggling to cope. They are requesting and require better community care. Implementing a culturally safe model of dementia care for remote Aboriginal communities that encompasses the recommendations made and builds on the strengths of the communities could potentially deliver the required improvements to dementia care for this population.

An autonomous remote clock control system is proposed to provide time synchronization and frequency syntonization for satellite to satellite or ground to satellite time transfer, with the system comprising on-board voltage controlled oven controlled crystal oscillators (VC-OCXOs) that are disciplined to a remote master atomic clock or oscillator. The synchronization loop aims to provide autonomous operation over extended periods, be widely applicable to a variety of scenarios and robust. A new architecture comprising the use of frequency division duplex (FDD), synchronous time division (STDD) duplex and code division multiple access (CDMA) with a centralized topology is employed. This new design utilizes dual one-way ranging methods to precisely measure the clock error, adopts least square (LS) methods to predict the clock error and employs a third-order phase lock loop (PLL) to generate the voltage control signal. A general functional model for this system is proposed and the error sources and delays that affect the time synchronization are discussed. Related algorithms for estimating and correcting these errors are also proposed. The performance of the proposed system is simulated and guidance for selecting the clock is provided. PMID:26213929

Intelligent distributed medical image management

Garcia, Hong-Mei C.; Yun, David Y.

1995-05-01

The rapid advancements in high performance global communication have accelerated cooperative image-based medical services to a new frontier. Traditional image-based medical services such as radiology and diagnostic consultation can now fully utilize multimedia technologies in order to provide novel services, including remote cooperative medical triage, distributed virtual simulation of operations, as well as cross-country collaborative medical research and training. Fast (efficient) and easy (flexible) retrieval of relevant images remains a critical requirement for the provision of remote medical services. This paper describes the database system requirements, identifies technological building blocks for meeting the requirements, and presents a system architecture for our target image database system, MISSION-DBS, which has been designed to fulfill the goals of Project MISSION (medical imaging support via satellite integrated optical network) -- an experimental high performance gigabit satellite communication network with access to remote supercomputing power, medical image databases, and 3D visualization capabilities in addition to medical expertise anywhere and anytime around the country. The MISSION-DBS design employs a synergistic fusion of techniques in distributed databases (DDB) and artificial intelligence (AI) for storing, migrating, accessing, and exploring images. The efficient storage and retrieval of voluminous image information is achieved by integrating DDB modeling and AI techniques for image processing while the flexible retrieval mechanisms are accomplished by combining attribute- based and content-based retrievals.

Improving actionable stroke knowledge of a witness or bystander, which in some cases are children, may improve response to an acute stroke event. We used a quasiexperimental pre-test post-test design to evaluate actionable stroke knowledge of 210 children aged 9 to 10 years in response to a single, 15-minute exposure to a stroke education video game conducted in the school computer laboratory. After immediate post-test, we provided remote password-protected online video game access and encouraged children to play at their leisure from home. An unannounced delayed post-test occurred 7 weeks later. Two hundred ten children completed pretest, 205 completed immediate post-test, whereas 198 completed delayed post-test. One hundred fifty-six (74%) children had Internet access at home, and 41 (26%), mostly girls, played the video game remotely. There was significant improvement in stroke symptom composite scores, calling 911, and all individual stroke knowledge items, including a distractor across the testing sequence (P<0.05). Children who played the video game remotely demonstrated significant improvement in knowledge of 1 symptom (sudden imbalance) compared with children who did not (P<0.05), although overall composite scores showed no difference. Stroke education video games may represent novel means for improving and sustaining actionable stroke knowledge of children.

Background: The provision of palliative care (PC) and opioids is difficult to ensure in remote areas in low- and middle-income countries. We describe here the set up of a home-care program in Sarawak (the Malaysian part of the Borneo Island), where half the population lives in villages that are difficult to access. Methods: The establishment of this program, initiated in 1994 by the Department of Radiotherapy of Sarawak General Hospital, consisted of training, empowering nurses, simplifying referral, facilitating access to medication, and increasing awareness among public and health professionals about PC. Results: The program has been sustainable and cost efficient, serving 936 patients in 2006. The total morphine usage in the program increased from <200 g in 1993 to >1400 g in 2006. The results show that pain medication can be provided even in remote areas with effective organization and empowerment of nurses, who were the most important determinants for the set up of this program. Education of family was also a key aspect. Conclusion: The authors believe that the experience gained in Sarawak may help other regions with low or middle resources in the set up of their PC program especially for their remote rural population.

Videoconferencing has been used to expand medical services to low-access populations and could increase access to genetic services at community sites where in-person visits with genetic providers are not available. To evaluate the feasibility of, patient feedback of, and cognitive and affective responses to remote two-way videoconferencing (RVC) telegenetic services at multiple sociodemographically diverse community practices without access to genetic providers. Patients at 3 community sites in 2 US states outside the host center completed RVC pretest (visit 1, V1) and post-test (visit 2, V2) genetic counseling for cancer susceptibility. Surveys evaluated patient experiences, knowledge, satisfaction with telegenetic and cancer genetics services, anxiety, depression, and cancer worry. A total of 82 out of 100 (82.0%) approached patients consented to RVC services. A total of 61 out of 82 patients (74%) completed pretest counseling and 41 out of 61 (67%) proceeded with testing and post-test counseling. A total of 4 out of 41 (10%) mutation carriers were identified: BRCA2, MSH2, and PMS2. Patients reported many advantages (eg, lower travel burden and convenience) and few disadvantages to RVC telegenetic services. Most patients reported feeling comfortable with the video camera--post-V1: 52/57 (91%); post-V2: 39/41 (95%)--and that their privacy was respected--post-V1: 56/57 (98%); post-V2: 40/41 (98%); however, some reported concerns that RVC might increase the risk of a confidentiality breach of their health information--post-V1: 14/57 (25%); post-V2: 12/41 (29%). While the majority of patients reported having no trouble seeing or hearing the genetic counselor--post-V1: 47/57 (82%); post-V2: 39/41 (95%)--51 out of 98 (52%) patients reported technical difficulties. Nonetheless, all patients reported being satisfied with genetic services. Compared to baseline, knowledge increased significantly after pretest counseling (+1.11 mean score, P=.005); satisfaction with telegenetic (+1.74 mean score, P=.02) and genetic services (+2.22 mean score, P=.001) increased after post-test counseling. General anxiety and depression decreased after pretest (-0.97 mean anxiety score, P=.003; -0.37 mean depression score, P=.046) and post-test counseling (-1.13 mean anxiety score, P=.003; -0.75 mean depression score, P=.01); state anxiety and cancer-specific worry did not significantly increase. Remote videoconferencing telegenetic services are feasible, identify genetic carriers in community practices, and are associated with high patient satisfaction and favorable cognitive and affective outcomes, suggesting an innovative delivery model for further study to improve access to genetic providers and services. Potential barriers to dissemination include technology costs, unclear billing and reimbursement, and state requirements for provider licensure.

The Unidata Program Center (Unidata) of the University Corporation of Atmospheric Research (UCAR) is actively involved in international collaborations whose goals are the free-and-open sharing of hydro-meteorological data; the distribution of analysis and visualization tools for those data; the establishment of server technologies that provide easy-to-use, programmatic remote-access to a wide variety of datasets, and in the building of a community where data, tools, and best practices in education and research are shared. The tools and services provided by Unidata are available to the research and education community free-of-charge. Data sharing capabilities are being provided by Unidata's Internet Data Distribution (IDD) system, a community-based effort that has been the primary source of real-time meteorological data in the US university community for over a decade. A collaboration among Unidata, Brazil's Centro de Previso de Tempo e Estudos Climaticos (CPTEC), the Universidad Federal do Rio de Janeiro (UFRJ), and the Universidade de Sao Paulo (USP) has resulted in the creation of a Brazilian peer of the North American IDD, the IDD-Brasil. Collaboration between Unidata and the Universidad de Costa Rica (UCR) seeks to extend IDD data sharing throughout Central America and the Caribbean in an IDD-Caribe. Efforts aimed at creating a data sharing network for researchers on the Antarctic continent have resulted in the establishment of the Antarctic-IDD. Most recently, explorations of data sharing between UCAR and select countries in Africa have begun. Data analysis and visualization capabilities are available through Unidata in a suite of freely-available applications: the National Centers for Environmental Prediction (NCEP) GEneral Meteorology PAcKage (GEMPAK); the Unidata Integrated Data Viewer (IDV); and University of Wisconsin, Space Science and Engineering Center (SSEC) Man-computer Interactive Data Access System (McIDAS). Remote data access capabilities are provided by Unidata's Thematic Realtime Environmental Data Services (THREDDS) servers (which incorporate Open-source Project for a Network Data Access (OPeNDAP) data services), and the Abstract Data Distribution Environment (ADDE) of McIDAS. It is envisioned that the data sharing capabilities available in the IDD, IDD-Brasil, IDD-Caribe, and Antarctic-IDD, remote data access capabilities available in THREDDS and ADDE, and analysis capabilities available in GEMPAK, the IDV, and McIDAS will help foster new collaborations among prominent universities, national meteorological agencies, and WMO Regional Meteorological Training Centers throughout North, Central, and South America, in the Antarctic research community, and eventually in Africa. This paper is intended to inform AGU 2007 Joint Assembly attendees, especially those in Mexico and Central America, of the availability of real-time data and tools to analyze/visualize those data, and to promote the free-and-open sharing of data, especially of locally-held datasets of general interest.

Balancing access to health data and privacy: a review of the issues and approaches for the future.

PubMed

Lane, Julia; Schur, Claudia

2010-10-01

There has been a dramatic increase in the types of microdata, and this holds great promise for health services research. However, legislative efforts to protect individual privacy have reduced the flow of health care data for research purposes and increased costs and delays, affecting the quality of analysis. This paper provides an overview of the challenges raised by concerns about data confidentiality in the context of health services research, the current methodologies used to ensure data security, and a description of one successful approach to balancing access and privacy. Materials and Methods. We analyze the issues of access and privacy using a conceptual framework based on balancing the risk of reidentification with the utility associated with data analysis. The guiding principle should be to generate released data that are as close to the maximum acceptable risk as possible. HIPAA and other privacy measures can perhaps be seen as having had the effect of lowering the "maximum acceptable risk" level and rendering some data unreleasable. We discuss the levels of risk and utility associated with different types of data used in health services research and the ability to link data from multiple sources as well as current models of data sharing and their limitations. One particularly compelling approach is to establish a remote access "data enclave," where statistical protections are applied to the data, technical protections ensure compliance with data-sharing requirements, and operational controls limit researchers' access to the data they need for their specific research questions. We recommend reducing delays in access to data for research, increasing the use of remote access data enclaves, and disseminating knowledge and promulgating standards for best practices related to data protection. © Health Research and Educational Trust.

The viability of mobile communications is examined within the context of a frequency division multiple access, single channel per carrier satellite system emphasizing digital techniques to serve a large population of users. The intent is to provide the mobile users with a grade of service consistant with the requirements for remote, rural (perhaps emergency) voice communications, but which approaches toll quality speech. A traffic model is derived on which to base the determination of the required maximum number of satellite channels to provide the anticipated level of service. Various voice digitalization and digital modulation schemes are reviewed along with a general link analysis of the mobile system. Demand assignment multiple access considerations and analysis tradeoffs are presented. Finally, a completed configuration is described.

Construction of a virtual EPR and automated contextual linkage to multiple sources of support information on the Oxford Clinical Intranet.

We have used internet-standard tools to provide access for clinicians to the components of the electronic patient record held on multiple remote disparate systems. Through the same interface we have provided access to multiple knowledgebases, some written locally and others published elsewhere. We have developed linkage between these two types of information which removes the need for the user to drill down into each knowledgebase to search for relevant information. This approach may help in the implementation of evidence-based practice. The major problems appear to be semantic rather than technological. The intranet was developed at low cost and is now in routine use. This approach appears to be transferable across systems and organisations.

DARWIN is a NASA developed, Internet-based system for enabling aerospace researchers to securely and remotely access and collaborate on the analysis of aerospace vehicle design data, primarily the results of wind-tunnel testing and numeric (e.g., computational fluid dynamics) model executions. DARWIN captures, stores and indexes data, manages derived knowledge (such as visualizations across multiple data sets) and provides an environment for designers to collaborate in the analysis of the results of testing. DARWIN is an interesting application because it supports high volumes of data, integrates multiple modalities of data display (e.g. images and data visualizations), and provides non-trivial access control mechanisms. DARWIN enables collaboration by allowing not only sharing visualizations of data, but also commentary about and view of data.

To identify and review innovations relevant to improving access, quality, efficiency and/or effectiveness in the organization and delivery of health care services in rural and remote areas. Literature review. Key bibliographic databases that index health research were searched: MEDLINE, EMBASE and CINAHL. Other databases relevant to Arctic health were also accessed. Abstracts were assessed for relevancy and full articles were reviewed and categorized according to emergent themes. Many innovations in delivering services to rural and remote areas were identified, particularly in the public health realm. These innovations were grouped into 4 key themes: organizational structure of health services; utilization of telehealth and ehealth; medical transportation; and public health challenges. Despite the challenges facing rural and remote regions, there is a distinctly positive message from this broad literature review. Evidence-based initiatives exist across a range of areas - which include operational efficiency and integration, access to care, organizational structure, public health, continuing education and workforce composition - that have the potential to positively impact health care quality and health-related outcomes.

Introduction The termination of unwanted pregnancies up to 12 weeks’ gestation became legal in Nepal in 2002. Many interventions have taken place to expand access to comprehensive abortion care services. However, comprehensive abortion care services remain out of reach for women in rural and remote areas. This article describes a training and support strategy to train auxiliary nurse‐midwives (ANMs), already certified as skilled birth attendants, as medical abortion providers and expand geographic access to safe abortion care to the community level in Nepal. Methods This was a descriptive program evaluation. Sites and trainees were selected using standardized assessment tools to determine minimum facility requirements and willingness to provide medical abortion after training. Training was evaluated via posttests and observational checklists. Service statistics were collected through the government's facility logbook for safe abortion services (HMIS‐11). Results By the end of June 2014, medical abortion service had been expanded to 25 districts through 463 listed ANMs at 290 listed primary‐level facilities and served 25,187 women. Providers report a high level of confidence in their medical abortion skills and considerable clinical knowledge and capacity in medical abortion. Discussion The Nepali experience demonstrates that safe induced abortion care can be provided by ANMs, even in remote primary‐level health facilities. Post‐training support for providers is critical in helping ANMs handle potential barriers to medical abortion service provision and build lasting capacity in medical abortion. PMID:26860072

Remote-controlled aerial drones (or unmanned aerial vehicles; UAVs) are employed for surveillance by the military and police, which suggests that drone-captured footage might provide sufficient information for person identification. This study demonstrates that person identification from drone-captured images is poor when targets are unfamiliar (Experiment 1), when targets are familiar and the number of possible identities is restricted by context (Experiment 2), and when moving footage is employed (Experiment 3). Person information such as sex, race and age is also difficult to access from drone-captured footage (Experiment 4). These findings suggest that such footage provides a particularly poor medium for person identification. This is likely to reflect the sub-optimal quality of such footage, which is subject to factors such as the height and velocity at which drones fly, viewing distance, unfavourable vantage points, and ambient conditions.

Rates of chronic non-cancer pain are increasing worldwide, with concerns regarding poorer access to specialist treatment services in remote areas. The current study comprised the first in-depth examination of use and barriers to access of health services in Australia according to remoteness. A cohort of Australian adults prescribed pharmaceutical opioids for chronic non-cancer pain (n = 1,235) were interviewed between August 2012 and April 2014, and grouped into 'major city' (49%), 'inner regional' (37%), and 'outer regional/remote' (14%) according to the Australian Standard Geographical Classification based on postcode. Multinomial logistic regression analyses were conducted to determine geographical differences in socio-demographic and clinical characteristics, health service use, and perceived barriers to health service access. The 'inner regional group' and 'outer regional/remote group' were more likely to be male (relative risk ratio (RRR)=1.38,95%CI 1.08-1.77 and RRR = 1.60, 95%CI 1.14-2.24) and have no private health insurance (RRR = 1.53, 95%CI 1.19-1.97 and RRR = 1.65, 95%CI 1.16-2.37) than the 'major city group' (49%). However, the 'inner regional group' reported lower pain severity and better mental health relative to the 'major city group' = 0.92, 95%CI 0.86-0.98 and RRR = 1.02, 95%CI 1.01-1.03, respectively). Although rates of health service access were generally similar, the 'outer regional/remote group' were more likely to report client-practitioner communication problems (RRR = 1.57, 95%CI 1.03-2.37), difficulties accessing specialists (RRR = 1.56, 95%CI 1.01-2.39), and perception of practitioner lack of confidence in prescribing pain medication (RRR = 1.73, 1.14-2.62), relative to both groups. Perceived communication, access, and financial barriers to healthcare indicate the need for increased efforts to address geographic inequality in pain treatment. © 2016 American Academy of Pain Medicine.

2014-12-01

As the quantity of Earth-observation data increases, the use-case for hosting analytical tools in geospatial data centers becomes increasingly attractive. To address this need, HySpeed Computing and Exelis VIS have developed the HICO Image Processing System, a prototype cloud computing system that provides online, on-demand, scalable remote sensing image processing capabilities. The system provides a mechanism for delivering sophisticated image processing analytics and data visualization tools into the hands of a global user community, who will only need a browser and internet connection to perform analysis. Functionality of the HICO Image Processing System is demonstrated using imagery from the Hyperspectral Imager for the Coastal Ocean (HICO), an imaging spectrometer located on the International Space Station (ISS) that is optimized for acquisition of aquatic targets. Example applications include a collection of coastal remote sensing algorithms that are directed at deriving critical information on water and habitat characteristics of our vulnerable coastal environment. The project leverages the ENVI Services Engine as the framework for all image processing tasks, and can readily accommodate the rapid integration of new algorithms, datasets and processing tools.

Software Supports Distributed Operations via the Internet

Multi-mission Encrypted Communication System (MECS) is a computer program that enables authorized, geographically dispersed users to gain secure access to a common set of data files via the Internet. MECS is compatible with legacy application programs and a variety of operating systems. The MECS architecture is centered around maintaining consistent replicas of data files cached on remote computers. MECS monitors these files and, whenever one is changed, the changed file is committed to a master database as soon as network connectivity makes it possible to do so. MECS provides subscriptions for remote users to automatically receive new data as they are generated. Remote users can be producers as well as consumers of data. Whereas a prior program that provides some of the same services treats disconnection of a user from the network of users as an error from which recovery must be effected, MECS treats disconnection as a nominal state of the network: This leads to a different design that is more efficient for serving many users, each of whom typically connects and disconnects frequently and wants only a small fraction of the data at any given time.

Abstract The following telestroke guidelines were developed to assist practitioners in providing assessment, diagnosis, management, and/or remote consultative support to patients exhibiting symptoms and signs consistent with an acute stroke syndrome, using telemedicine communication technologies. Although telestroke practices may include the more broad utilization of telemedicine across the entire continuum of stroke care, with some even consulting on all neurologic emergencies, this document focuses on the acute phase of stroke, including both pre- and in-hospital encounters for cerebrovascular neurological emergencies. These guidelines describe a network of audiovisual communication and computer systems for delivery of telestroke clinical services and include operations, management, administration, and economic recommendations. These interactive encounters link patients with acute ischemic and hemorrhagic stroke syndromes with acute care facilities with remote and on-site healthcare practitioners providing access to expertise, enhancing clinical practice, and improving quality outcomes and metrics. These guidelines apply specifically to telestroke services and they do not prescribe or recommend overall clinical protocols for stroke patient care. Rather, the focus is on the unique aspects of delivering collaborative bedside and remote care through the telestroke model. PMID:28384077

Personalized Technologies in Chronic Gastrointestinal Disorders: Self-monitoring and Remote Sensor Technologies

PubMed Central

Riaz, Muhammad Safwan; Atreja, Ashish

2016-01-01

With increased access to high-speed Internet and smartphone devices, patients have started to use mobile applications (apps) for various health needs. These mobile apps are now increasingly used in integration with telemedicine and wearables to support fitness, health education, symptom tracking, and collaborative disease management and care coordination. More recently, evidence (especially around remote patient monitoring) has started to build in some chronic diseases, and some of the digital health technologies have received approval from the Food and Drug Administration. With the changing healthcare landscape and push for value-based care, adoption of these digital health initiatives among providers is bound to increase. Although so far there is a dearth of published evidence about effectiveness of these apps in gastroenterology care, there are ongoing trials to determine whether remote patient monitoring can lead to improvement in process metrics or outcome metrics for patients with chronic gastrointestinal diseases.

We successfully created and implemented an effective HIV rapid testing training and certification curriculum using traditional in-person training at multiple sites within the U.S. Department of Veterans Affairs (VA) Healthcare System. Considering the multitude of geographically remote facilities in the nationwide VA system, coupled with the expansion of HIV diagnostics, we developed an alternate training method that is affordable, efficient, and effective. Using materials initially developed for in-person HIV rapid test in-services, we used a distance learning model to offer this training via live audiovisual online technology to educate clinicians at a remote outpatient primary care VA facility. Participants' evaluation metrics showed that this form of remote education is equivalent to in-person training; additionally, HIV testing rates increased considerably in the months following this intervention. Although there is a one-time setup cost associated with this remote training protocol, there is potential cost savings associated with the point-of-care nurse manager's time productivity by using the Internet in-service learning module for teaching HIV rapid testing. If additional in-service training modules are developed into Internet-based format, there is the potential for additional cost savings. Our cost analysis demonstrates that the remote in-service method provides a more affordable and efficient alternative compared with in-person training. The online in-service provided training that was equivalent to in-person sessions based on first-hand supervisor observation, participant satisfaction surveys, and follow-up results. This method saves time and money, requires fewer personnel, and affords access to expert trainers regardless of geographic location. Further, it is generalizable to training beyond HIV rapid testing. Based on these consistent implementation successes, we plan to expand use of online training to include remote VA satellite facilities spanning several states for a variety of diagnostic devices. Ultimately, Internet-based training has the potential to provide "big city" quality of care to patients at remote (rural) clinics.

Networks of video cameras, meteorological sensors, and ancillary electronic equipment are under development in collaboration among NASA Ames Research Center, the Federal Aviation Administration (FAA), and the National Oceanic Atmospheric Administration (NOAA). These networks are to be established at and near airports to provide real-time information on local weather conditions that affect aircraft approaches and landings. The prototype network is an airport-approach-zone camera system (AAZCS), which has been deployed at San Francisco International Airport (SFO) and San Carlos Airport (SQL). The AAZCS includes remotely controlled color video cameras located on top of SFO and SQL air-traffic control towers. The cameras are controlled by the NOAA Center Weather Service Unit located at the Oakland Air Route Traffic Control Center and are accessible via a secure Web site. The AAZCS cameras can be zoomed and can be panned and tilted to cover a field of view 220 wide. The NOAA observer can see the sky condition as it is changing, thereby making possible a real-time evaluation of the conditions along the approach zones of SFO and SQL. The next-generation network, denoted a remote tower sensor system (RTSS), will soon be deployed at the Half Moon Bay Airport and a version of it will eventually be deployed at Los Angeles International Airport. In addition to remote control of video cameras via secure Web links, the RTSS offers realtime weather observations, remote sensing, portability, and a capability for deployment at remote and uninhabited sites. The RTSS can be used at airports that lack control towers, as well as at major airport hubs, to provide synthetic augmentation of vision for both local and remote operations under what would otherwise be conditions of low or even zero visibility.

The Physical Oceanography Distributed Active Archive Center (PO.DAAC) is NASA's archive, steward and distributor for physical oceanographic satellite data. Those data are typically organized along the lines of single parameters, such as Sea Surface Temperature, Ocean Winds, Salinity, etc. However there is a need supplement satellite data with in situ and various other remote sensing data to provide higher spatial and temporal sampling and information on physical processes that the satellites are not capable of measuring. This presentation will discuss how PO.DAAC is creating a stewardship and distribution plan that will accommodate satellite, in situ and other remote sensing data that can be used to solve a more integrated approach to data access and utilization along thematic lines in support of science and applications, specifically those posed by Salinity Processes in the Upper Ocean Regional Study (SPURS) and Oceans Melting Greenland (OMG) projects. SPURS used shipboard data, moorings and in situ instruments to investigate changes in salinity and how that information can be used in explaining the water cycle. OMG is studying ice melt in Greenland and how it contributes to changes in sea level through shipboard measurements, airborne and a variety of in situ instruments. PO.DAAC plans on adapting to stewarding and distributing these varieties of data through applications of file format and metadata standards (so data are discoverable and interoperable), extend the internal data system (to allow for better archiving, collection generation and querying of in situ and airborne data) and integration into tools (visualization and data access). We are also working on Virtual Collections with ESDWG, which could provide access to relevant data across DAACs/Agencies along thematic lines. These improvements will improve long-term data management and make it easier for users of various background, regardless if remote sensing or in situ, to discover and use the data.

Service user preferences for diabetes education in remote and rural areas of the Highlands and Islands of Scotland.

Diabetes prevalence in Scotland is 5.3%, with type 2 diabetes accounting for 86.7% of all cases in the National Health Service Highlands health board area and 85.7% in the Western Isles. Structured education is a key component in the management of this chronic disease. However, current group session models are less feasible in lower-population non-urban environments due to distance, participant numbers and access to appropriately trained healthcare professionals. Group sessions may also be a less attractive option in small communities, where people tend to have close day-to-day personal contact. This study assesses the access and delivery preferences of remote and rural service users in the Highlands and Western Isles to structured diabetes education programs. The study used a mixed methods approach of focus groups and questionnaires with people with type 2 diabetes in the Highlands and Islands of Scotland. Both modes of participation were designed to explore perception of diabetes knowledge, diabetes education and use of technology. One-to-one delivery was the delivery method of choice; however, there was a preference for a digital approach over group education sessions. Service users expressed a strong desire to be able to learn at their own pace, when and where they wanted to, and with no requirement to travel. To address these requirements an online resource, providing access to both learning sessions and trusted sources of information, was the preferred mode of delivery. People with type 2 diabetes living in remote and rural areas of the Scottish Highlands and Islands who already use the internet are receptive to the use of digital technology for delivery of diabetes education and are interested in learning more about management of their condition through this medium. They believe that a technology approach will provide them with more control over the pace of learning, and where and when this learning can take place.

As the ability to buy gas and transportation services directly from suppliers becomes available to small commercial and residential customers, local distribution companies (LDCs) are evaluating how to measure and track their consumption. The LDCs often measure the gas use of large commercial and industrial customers with remote, automated meter-reading (AMR) devices, many of which provide real-time data. The utility can justify the expense of installing these devices because of the customers` considerable gas consumption. But for customers who already contribute very little to margins, AMR investments by LDCs are more problematic.

The Deep Space Network (DSN) communicates with spacecraft as far away as the boundary between the Solar System and the interstellar medium. To make this possible, large sensitive antennas at Canberra, Australia, Goldstone, California, and Madrid, Spain, provide for constant communication with interplanetary missions. We describe the procedures for radioastronomical observations using this network. Remote access to science monitor and control computers by authorized observers is provided by two-factor authentication through a gateway at the Jet Propulsion Laboratory (JPL) in Pasadena. To make such observations practical, we have devised schemes based on SSH tunnels and distributed computing. At the very minimum, one can use SSH tunnels and VNC (Virtual Network Computing, a remote desktop software suite) to control the science hosts within the DSN Flight Operations network. In this way we have controlled up to three telescopes simultaneously. However, X-window updates can be slow and there are issues involving incompatible screen sizes and multi-screen displays. Consequently, we are now developing SSH tunnel-based schemes in which instrument control and monitoring, and intense data processing, are done on-site by the remote DSN hosts while data manipulation and graphical display are done at the observer's host. We describe our approaches to various challenges, our experience with what worked well and lessons learned, and directions for future development.

A web-based database system for intelligent remote monitoring of an artificial heart has been developed. It is important for patients with an artificial heart implant to be discharged from the hospital after an appropriate stabilization period for better recovery and quality of life. Reliable continuous remote monitoring systems for these patients with life support devices are gaining practical meaning. The authors have developed a remote monitoring system for this purpose that consists of a portable/desktop monitoring terminal, a database for continuous recording of patient and device status, a web-based data access system with which clinicians can access real-time patient and device status data and past history data, and an intelligent diagnosis algorithm module that noninvasively estimates blood pump output and makes automatic classification of the device status. The system has been tested with data generation emulators installed on remote sites for simulation study, and in two cases of animal experiments conducted at remote facilities. The system showed acceptable functionality and reliability. The intelligence algorithm also showed acceptable practicality in an application to animal experiment data.

Secure distribution for high resolution remote sensing images

Liu, Jin; Sun, Jing; Xu, Zheng Q.

2010-09-01

The use of remote sensing images collected by space platforms is becoming more and more widespread. The increasing value of space data and its use in critical scenarios call for adoption of proper security measures to protect these data against unauthorized access and fraudulent use. In this paper, based on the characteristics of remote sensing image data and application requirements on secure distribution, a secure distribution method is proposed, including users and regions classification, hierarchical control and keys generation, and multi-level encryption based on regions. The combination of the three parts can make that the same remote sensing images after multi-level encryption processing are distributed to different permission users through multicast, but different permission users can obtain different degree information after decryption through their own decryption keys. It well meets user access control and security needs in the process of high resolution remote sensing image distribution. The experimental results prove the effectiveness of the proposed method which is suitable for practical use in the secure transmission of remote sensing images including confidential information over internet.

The ISS finally reached an operational state and exists for local and remote users. Onboard payload systems are managed by the Huntsville Operations Support Center (HOSC). Users access HOSC systems by internet protocols in support of daily operations, preflight simulation, and test. In support of this diverse user community, a modem security architecture has been implemented. The architecture has evolved over time from an isolated but open system to a system which supports local and remote access to the ISS over broad geographic regions. This has been accomplished through the use of an evolved security strategy, PKI, and custom design. Through this paper, descriptions of the migration process and the lessons learned are presented. This will include product decision criteria, rationale, and the use of commodity products in the end architecture. This paper will also stress the need for interoperability of various products and the effects of seemingly insignificant details.

2013-12-01

Timely identification of areas affected by natural disasters is very important for a successful rescue and effective emergency relief efforts. This research focuses on the development of a cost effective and efficient system of identifying areas affected by natural disasters, and the efficient distribution of the information. The developed system is composed of 3 modules which are the Web Processing Service (WPS), Web Map Service (WMS) and the user interface provided by J-iView (fig. 1). WPS is an online system that provides computation, storage and data access services. In this study, the WPS module provides online access of the software implementing the developed frequency based change detection algorithm for the identification of areas affected by natural disasters. It also sends requests to WMS servers to get the remotely sensed data to be used in the computation. WMS is a standard protocol that provides a simple HTTP interface for requesting geo-registered map images from one or more geospatial databases. In this research, the WMS component provides remote access of the satellite images which are used as inputs for land cover change detection. The user interface in this system is provided by J-iView, which is an online mapping system developed at the Geological Survey of Japan (GSJ). The 3 modules are seamlessly integrated into a single package using J-iView, which could rapidly generate a map of disaster areas that is instantaneously viewable online. The developed system was tested using ASTER images covering the areas damaged by the March 11, 2011 tsunami in northeastern Japan. The developed system efficiently generated a map showing areas devastated by the tsunami. Based on the initial results of the study, the developed system proved to be a useful tool for emergency workers to quickly identify areas affected by natural disasters.

Taylor, Andrea; French, Tara; Raman, Sneha

2018-03-01

Providing access to hospice services will become increasingly difficult due to the pressures of an ageing population and limited resources. To help address this challenge, a small number of services called Virtual Hospice have been established. This paper presents early-stage design work on a Virtual Hospice to improve access to services provided by a hospice (Highland Hospice) serving a largely remote and rural population in Scotland, UK. The study was structured as a series of Experience Labs with Highland Hospice staff, healthcare professionals and patients. Experience Labs employ a participatory design approach where participants are placed at the centre of the design process, helping to ensure that the resultant service meets their needs. Data from the Experience Labs were analysed using qualitative thematic analysis and design analysis. A number of themes and barriers to accessing Highland Hospice services were identified. In response, an initial set of seven design principles was developed. Design principles are high-level guidelines that are used to improve prioritisation and decision making during the design process by ensuring alignment with research insights. The design principles were piloted with a group of stakeholders and gained positive feedback. The design principles are intended to guide the ongoing development of the Highland Hospice Virtual Hospice. However, the challenges faced by Highland Hospice in delivering services in a largely remote and rural setting are not unique. The design principles, encompassing digital and non-digital guidelines, or the design approach could be applied by other hospices in the UK or overseas. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

DICOM-compliant PACS with CD-based image archival

NASA Astrophysics Data System (ADS)

Cox, Robert D.; Henri, Christopher J.; Rubin, Richard K.; Bret, Patrice M.

1998-07-01

This paper describes the design and implementation of a low- cost PACS conforming to the DICOM 3.0 standard. The goal was to provide an efficient image archival and management solution on a heterogeneous hospital network as a basis for filmless radiology. The system follows a distributed, client/server model and was implemented at a fraction of the cost of a commercial PACS. It provides reliable archiving on recordable CD and allows access to digital images throughout the hospital and on the Internet. Dedicated servers have been designed for short-term storage, CD-based archival, data retrieval and remote data access or teleradiology. The short-term storage devices provide DICOM storage and query/retrieve services to scanners and workstations and approximately twelve weeks of 'on-line' image data. The CD-based archival and data retrieval processes are fully automated with the exception of CD loading and unloading. The system employs lossless compression on both short- and long-term storage devices. All servers communicate via the DICOM protocol in conjunction with both local and 'master' SQL-patient databases. Records are transferred from the local to the master database independently, ensuring that storage devices will still function if the master database server cannot be reached. The system features rules-based work-flow management and WWW servers to provide multi-platform remote data access. The WWW server system is distributed on the storage, retrieval and teleradiology servers allowing viewing of locally stored image data directly in a WWW browser without the need for data transfer to a central WWW server. An independent system monitors disk usage, processes, network and CPU load on each server and reports errors to the image management team via email. The PACS was implemented using a combination of off-the-shelf hardware, freely available software and applications developed in-house. The system has enabled filmless operation in CT, MR and ultrasound within the radiology department and throughout the hospital. The use of WWW technology has enabled the development of an intuitive we- based teleradiology and image management solution that provides complete access to image data.

Health worker recruitment and deployment in remote areas of Indonesia.

Efendi, Ferry

2012-01-01

Providing health care in remote and very remote areas has long been a major concern in Indonesia. In order to improve access to quality health care for residents in these areas, various policies on recruitment and deployment of health workers have been implemented, among them compulsory service, contracted staff and the Special Assignment of strategic health workers. Indonesia's difficult geography presents great challenges to health service delivery and most health workers prefer to serve in urban areas, resulting in an uneven distribution of health workers and shortages in remote areas. Great efforts have been made to mobilize health human resources more equitably, including placement schemes for strategic health workers and contracted staff, combined with an incentive scheme. While these have partially addressed the severe shortage of health workers in remote areas, current government policies were reviewed in order to clarify the current situation in Indonesia. The Contracted Staff and Special Assignment of Strategic Health Workers programs show have made a significant contribution to improving the availability of health workers in Indonesia's remote areas. As these two programs used financial incentives as the main intervention, other non-financial interventions should also be trialed. For example, incentives such as the promise of a civil servant appointment or the provision of continuing professional education, as well as the recruitment of rural-background health workers may increase the willingness of health staff to serve in the remote and very remote areas of Indonesia.

Data management constitutes one of the major challenges that a geographically- distributed e-Infrastructure has to face, especially when remote data access is involved. We discuss an integrated solution which enables transparent and efficient access to on-line and near-line data through high latency networks. The solution is based on the joint use of the General Parallel File System (GPFS) and of the Tivoli Storage Manager (TSM). Both products, developed by IBM, are well known and extensively used in the HEP computing community. Owing to a new feature introduced in GPFS 3.5, so-called Active File Management (AFM), the definition of a single, geographically-distributed namespace, characterised by automated data flow management between different locations, becomes possible. As a practical example, we present the implementation of AFM-based remote data access between two data centres located in Bologna and Rome, demonstrating the validity of the solution for the use case of the AMS experiment, an astro-particle experiment supported by the INFN CNAF data centre with the large disk space requirements (more than 1.5 PB).

We are developing a unified distributed communication environment for processing of spatial data which integrates web-, desktop- and mobile platforms and combines volunteer computing model and public cloud possibilities. The main idea is to create a flexible working environment for research groups, which may be scaled according to required data volume and computing power, while keeping infrastructure costs at minimum. It is based upon the "single window" principle, which combines data access via geoportal functionality, processing possibilities and communication between researchers. Using an innovative software environment the recently developed planetary information system (http://cartsrv.mexlab.ru/geoportal) will be updated. The new system will provide spatial data processing, analysis and 3D-visualization and will be tested based on freely available Earth remote sensing data as well as Solar system planetary images from various missions. Based on this approach it will be possible to organize the research and representation of results on a new technology level, which provides more possibilities for immediate and direct reuse of research materials, including data, algorithms, methodology, and components. The new software environment is targeted at remote scientific teams, and will provide access to existing spatial distributed information for which we suggest implementation of a user interface as an advanced front-end, e.g., for virtual globe system.

Medical e-commerce for regional Australia.

The residents of rural and regional Australia have less access to health care services than in capital cities. There is a reluctance of General Practitioners to practice in the country. New information technology and government initiatives are now addressing this problem. High bandwidth videoconferencing is now being routinely used to provide psychiatric consultations to areas without this service. But this (like many other implementations of telecommunication technologies to health) has resulted in loss of revenue to regional Australia while benefiting capital cities. Thus, the current implementation of telecommunication technology to health has resulted in loss of revenue of the regions while increasing the bias towards the cities. Further, the system is not economically viable and requires the Government to inject funds for the smooth operation of the system. This paper proposes the use of telecommunication technology for enabling the communities of regional Australia to access health facilities via physical and virtual clinics. The proposed technique is self supporting and is based in the country with the intent to prevent the drain of resources from regional Australia. The technique attempts to eradicate the problem at the root level by providing a business opportunity that is based in and to cater for the needs of the remote communities. The proposed system would provide health services by physical and virtual clinics and while serving the communities would be profit centres- and thus attracting doctors and other resources to the remote communities.

Meta Data Mining in Earth Remote Sensing Data Archives

NASA Astrophysics Data System (ADS)

Davis, B.; Steinwand, D.

2014-12-01

Modern search and discovery tools for satellite based remote sensing data are often catalog based and rely on query systems which use scene- (or granule-) based meta data for those queries. While these traditional catalog systems are often robust, very little has been done in the way of meta data mining to aid in the search and discovery process. The recently coined term "Big Data" can be applied in the remote sensing world's efforts to derive information from the vast data holdings of satellite based land remote sensing data. Large catalog-based search and discovery systems such as the United States Geological Survey's Earth Explorer system and the NASA Earth Observing System Data and Information System's Reverb-ECHO system provide comprehensive access to these data holdings, but do little to expose the underlying scene-based meta data. These catalog-based systems are extremely flexible, but are manually intensive and often require a high level of user expertise. Exposing scene-based meta data to external, web-based services can enable machine-driven queries to aid in the search and discovery process. Furthermore, services which expose additional scene-based content data (such as product quality information) are now available and can provide a "deeper look" into remote sensing data archives too large for efficient manual search methods. This presentation shows examples of the mining of Landsat and Aster scene-based meta data, and an experimental service using OPeNDAP to extract information from quality band from multiple granules in the MODIS archive.

2008-04-01

The objective of this research was to determine the feasibility of and receptivity to the first computerized workplace-based direct caregiver intervention and to assess the effects on businesses, working family caregivers, and their elderly relatives. Working family caregivers, with at least one health and/or safety concern related to an elder residing alone at home during the workday, were recruited from five companies (n = 27). Caregivers received free computer access to the Worker Interactive Networking (WIN) Internet online caregiver support group and a remote elder monitoring system at home for 6 months. The remote monitoring system provided Web-based status reports and e-mail/pager alerts when individualized parameters were exceeded. Motion sensor signals were transmitted to a transponder that uploaded via wireless cellular communications to the project server, thereby not interfering with elders' telephone use. Formative qualitative analyses clarified acceptance and implementation issues. Summative quantitative evaluation determined pilot intervention effects and was conducted by external evaluators. Despite interoperability and cellular reception issues, the system was successfully deployed across four states to a variety of businesses and housing types. Positive results occurred on worker morale, productivity, and reduction of caregiver stress. Participants found it easy to learn and use. Elders did not find the technology "intrusive" or "isolating." Contrary to their expectations, managers reported no abuse of Internet access. Workers expressed a willingness to pay for a similar system in the future ranging from $10 to $130, depending on the features. They would pay the most for the option involving a geriatric nurse coach. The WIN system innovatively tailored to users' wants, and provided users customized control and personalized support. Use of the system was associated with positive outcomes. Enrollment response suggests a specific niche market for remote home monitoring, making it a manageable employee benefit.

Information recovery through image sequence fusion under wavelet transformation

NASA Astrophysics Data System (ADS)

He, Qiang

2010-04-01

Remote sensing is widely applied to provide information of areas with limited ground access with applications such as to assess the destruction from natural disasters and to plan relief and recovery operations. However, the data collection of aerial digital images is constrained by bad weather, atmospheric conditions, and unstable camera or camcorder. Therefore, how to recover the information from the low-quality remote sensing images and how to enhance the image quality becomes very important for many visual understanding tasks, such like feature detection, object segmentation, and object recognition. The quality of remote sensing imagery can be improved through meaningful combination of the employed images captured from different sensors or from different conditions through information fusion. Here we particularly address information fusion to remote sensing images under multi-resolution analysis in the employed image sequences. The image fusion is to recover complete information by integrating multiple images captured from the same scene. Through image fusion, a new image with high-resolution or more perceptive for human and machine is created from a time series of low-quality images based on image registration between different video frames.

Demonstration of centimeter-level precision, swath mapping, full-waveform laser altimetry from high altitude on the Global Hawk UAV for future application to cryospheric remote sensing

NASA Astrophysics Data System (ADS)

Blair, J. B.; Wake, S.; Rabine, D.; Hofton, M. A.; Mitchell, S.

2013-12-01

The Land Vegetation and Ice Sensor (LVIS) is a high-altitude, wide-swath laser altimeter that has, for over 15 years, demonstrated state-of-the-art performance in surface altimetry, including many aspects of remote sensing of the cryosphere such as precise topography of ice sheets and sea ice. NASA Goddard, in cooperation with NASA's Earth Science Technology Office (ESTO), has developed a new, more capable sensor that can operate autonomously from a high-altitude UAV aircraft to further enhance the LVIS capability and extend its reach and coverage. In June 2012, this latest sensor, known as LVIS-GH, was integrated onto NASA's Global Hawk aircraft and completed a successful high-altitude demonstration flight over Death Valley, Owens Valley, and the Sierra Nevada region of California. Data were collected over a wide variety of terrain types from 58,000' (> 17 km) altitude during the 6 hour long test flight. The full-waveform laser altimetry technique employed by LVIS and LVIS-GH provides precise surface topography measurements for solid earth and cryospheric applications and captures the vertical structure of forests in support of territorial ecology studies. LVIS-GH fully illuminates and maps a 4 km swath and provides cm-level range precision, as demonstrated in laboratory and horizontal range testing, as well as during this test flight. The cm range precision is notable as it applies to accurate measurements of sea ice freeboard and change detection of subtle surface deformation such as heaving in permafrost areas. In recent years, LVIS has primarily supported Operation IceBridge activities, including deployments to the Arctic and Antarctic on manned aircraft such as the NASA DC-8 and P-3. The LVIS-GH sensor provides an major upgrade of coverage capability and remote access; LVIS-GH operating on the long-duration Global Hawk aircraft can map up to 50,000 km^2 in a single flight and can provide access to remote regions such as the entirety of Antarctica. Future applications of LVIS-GH could include comprehensive mapping of cryosphere targets over large regions such as Alaska, Greenland, and Antarctica as well as an opportunity for seasonal mapping of sea and land ice. Data from the test flight will be presented along with accuracy assessment and specific examples of the cm-level range precision and wide swath mapping ability relevant to cryospheric remote sensing.

Index of Access: a new innovative and dynamic tool for rural health service and workforce planning.

McGrail, Matthew R; Russell, Deborah J; Humphreys, John S

2017-10-01

Objective Improving access to primary health care (PHC) remains a key issue for rural residents and health service planners. This study aims to show that how access to PHC services is measured has important implications for rural health service and workforce planning. Methods A more sophisticated tool to measure access to PHC services is proposed, which can help health service planners overcome the shortcomings of existing measures and long-standing access barriers to PHC. Critically, the proposed Index of Access captures key components of access and uses a floating catchment approach to better define service areas and population accessibility levels. Moreover, as demonstrated through a case study, the Index of Access enables modelling of the effects of workforce supply variations. Results Hypothetical increases in supply are modelled for a range of regional centres, medium and small rural towns, with resulting changes of access scores valuable to informing health service and workforce planning decisions. Conclusions The availability and application of a specific 'fit-for-purpose' access measure enables a more accurate empirical basis for service planning and allocation of health resources. This measure has great potential for improved identification of PHC access inequities and guiding redistribution of PHC services to correct such inequities. What is known about the topic? Resource allocation and health service planning decisions for rural and remote health settings are currently based on either simple measures of access (e.g. provider-to-population ratios) or proxy measures of access (e.g. standard geographical classifications). Both approaches have substantial limitations for informing rural health service planning and decision making. What does this paper add? The adoption of a new improved tool to measure access to PHC services, the Index of Access, is proposed to assist health service and workforce planning. Its usefulness for health service planning is demonstrated using a case study to hypothetically model changes in rural PHC workforce supply. What are the implications for practitioners? The Index of Access has significant potential for identifying how rural and remote primary health care access inequities can be addressed. This critically important information can assist health service planners, for example those working in primary health networks, to determine where and how much redistribution of PHC services is needed to correct existing inequities.

Chronic obstructive pulmonary disease (COPD) is a leading cause of mortality. Advances in remote technologies and telemedicine provide new ways to monitor respiratory function and improve chronic disease management. However, telemedicine does not always include remote respiratory assessments, and the current state of knowledge for people with COPD has not been evaluated. Systematically review the use of remote respiratory assessments in people with COPD, including the following questions: What devices have been used? Can acute exacerbations of chronic obstructive pulmonary disease (AECOPD) be predicted by using remote devices? Do remote respiratory assessments improve health-related outcomes? The review protocol was registered (PROSPERO 2016:CRD42016049333). MEDLINE, EMBASE, and COMPENDEX databases were searched for studies that included remote respiratory assessments in people with COPD. A narrative synthesis was then conducted by two reviewers according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Fifteen studies met the inclusion criteria. Forced expiratory volume assessed daily by using a spirometer was the most common modality. Other measurements included resting respiratory rate, respiratory sounds, and end-tidal carbon dioxide level. Remote assessments had high user satisfaction. Benefits included early detection of AECOPD, improved health-related outcomes, and the ability to replace hospital care with a virtual ward. Remote respiratory assessments are feasible and when combined with sufficient organizational backup can improve health-related outcomes in some but not all cohorts. Future research should focus on the early detection, intervention, and rehabilitation for AECOPD in high-risk people who have limited access to best care and investigate continuous as well as intermittent monitoring.

Three major obstacles facing big Earth data users include data storage, management, and analysis. As the amount of satellite remote sensing data increases, so does the need for better data storage and management strategies to exploit the plethora of data now available. Standard GIS tools can help big Earth data users whom interact with and analyze increasingly large and diverse datasets. In this presentation we highlight how NASA's Land Processes Distributed Active Archive Center (LP DAAC) is tackling these big Earth data challenges. We provide a real life use case example to describe three tools and services provided by the LP DAAC to more efficiently exploit big Earth data in a GIS environment. First, we describe the Open-source Project for a Network Data Access Protocol (OPeNDAP), which calls to specific data, minimizing the amount of data that a user downloads and improves the efficiency of data downloading and processing. Next, we cover the LP DAAC's Application for Extracting and Exploring Analysis Ready Samples (AppEEARS), a web application interface for extracting and analyzing land remote sensing data. From there, we review an ArcPython toolbox that was developed to provide quality control services to land remote sensing data products. Locating and extracting specific subsets of larger big Earth datasets improves data storage and management efficiency for the end user, and quality control services provides a straightforward interpretation of big Earth data. These tools and services are beneficial to the GIS user community in terms of standardizing workflows and improving data storage, management, and analysis tactics.

Remote Sensing of Arctic Environmental Conditions and Critical Infrastructure using Infra-Red (IR) Cameras and Unmanned Air Vehicles (UAVs)

Remote Sensing of Arctic Environmental Conditions and Critical Infrastructure using Infra-Red (IR) Cameras and Unmanned Air Vehicles (UAVs) Numerous scientific and logistical applications exist in Alaska and other arctic regions requiring analysis of expansive, remote areas in the near infrared (NIR) and thermal infrared (TIR) bands. These include characterization of wild land fire plumes and volcanic ejecta, detailed mapping of lava flows, and inspection of lengthy segments of critical infrastructure, such as the Alaska pipeline and railroad system. Obtaining timely, repeatable, calibrated measurements of these extensive features and infrastructure networks requires localized, taskable assets such as UAVs. The Alaska Center for Unmanned Aircraft Systems Integration (ACUASI) provides practical solutions to these problem sets by pairing various IR sensors with a combination of fixed-wing and multi-rotor air vehicles. Fixed-wing assets, such as the Insitu ScanEagle, offer long reach and extended duration capabilities to quickly access remote locations and provide enduring surveillance of the target of interest. Rotary-wing assets, such as the Aeryon Scout or the ACUASI-built Ptarmigan hexcopter, provide a precision capability for detailed horizontal mapping or vertical stratification of atmospheric phenomena. When included with other ground capabilities, we will show how they can assist in decision support and hazard assessment as well as giving those in emergency management a new ability to increase knowledge of the event at hand while reducing the risk to all involved. Here, in this presentation, we illustrate how UAV's can provide the ideal tool to map and analyze the hazardous events and critical infrastructure under extreme environmental conditions.

PubMed

Joshi, D; Baral, S C; Giri, S; Kumar, A M V

2016-12-21

Setting: Eight village development committees of Mugu District, a remote mountainous district of Nepal that has poor maternal health indicators. Objectives: 1) To assess the proportion of mothers who delivered in health facilities (institutional delivery); 2) among mothers who delivered at home, to understand their reasons for doing so; and 3) among mothers who delivered in health facilities, to understand their challenges. Design: Cross-sectional study involving semi-structured interviews with mothers conducted in 2015. Results: Of 275 mothers, 97 (35%) had an institutional delivery. Multivariate logistic regression analysis showed that women who resided within 1 h distance from the birthing centre, had adequate mass media exposure or had only one child were more likely to deliver in hospital. Reasons for non-institutional delivery ( n = 178) were related to geographical access (49%), personal preferences (18%) and perceived poor quality care (4%). Mothers who accessed institutional delivery ( n = 97) also reported difficulties related to travel (60%), costs (28%), dysfunctional health system (18%) and unfriendly attitudes of the health-care providers (7%). Conclusion: To improve access to institutional delivery, the government should establish a 24/7 emergency ambulance network, including air ambulance. Health system issues, including unfriendly staff attitudes, urgently need to be addressed to gain the trust of the mothers.

Results The evaluation of the system is being implemented among several UK Internet diabetes discussion groups and the Diabetes Day Centre at the Guy's & St. Thomas' Hospital. Many positive feedback are received from the web site demonstrating DiabNet is an advanced web-based diabetes management system which can help patients to keep closer control of self-monitoring blood glucose remotely, and is an integrated diabetes information resource that offers telemedicine knowledge in diabetes management. Discussion In summary, DiabNet introduces an innovative online diabetes management concept, such as online appointment and consultation, to enable users to access diabetes management information without time and location limitation and security concerns.

An efficient biometric and password-based remote user authentication using smart card for Telecare Medical Information Systems in multi-server environment.

PubMed

Maitra, Tanmoy; Giri, Debasis

2014-12-01

The medical organizations have introduced Telecare Medical Information System (TMIS) to provide a reliable facility by which a patient who is unable to go to a doctor in critical or urgent period, can communicate to a doctor through a medical server via internet from home. An authentication mechanism is needed in TMIS to hide the secret information of both parties, namely a server and a patient. Recent research includes patient's biometric information as well as password to design a remote user authentication scheme that enhances the security level. In a single server environment, one server is responsible for providing services to all the authorized remote patients. However, the problem arises if a patient wishes to access several branch servers, he/she needs to register to the branch servers individually. In 2014, Chuang and Chen proposed an remote user authentication scheme for multi-server environment. In this paper, we have shown that in their scheme, an non-register adversary can successfully logged-in into the system as a valid patient. To resist the weaknesses, we have proposed an authentication scheme for TMIS in multi-server environment where the patients can register to a root telecare server called registration center (RC) in one time to get services from all the telecare branch servers through their registered smart card. Security analysis and comparison shows that our proposed scheme provides better security with low computational and communication cost.

Ensuring quality of data during electronic data capture has been one of the most neglected components of operational research. Multicentre studies are also challenged with issues about logistics of travel, training, supervision, monitoring and troubleshooting support. Allocating resources to these issues can pose a significant bottleneck for operational research in resource-limited settings. In this article, we describe an innovative and efficient way of coordinating data capture in multicentre operational research using a combination of three open access technologies—EpiData for data capture, Dropbox for sharing files and TeamViewer for providing remote support.

Do astronomers want, need, or use online electronic books? At our large institution astronomers have access to a number of e-books, including monographs provided by various e-book vendors. After a marketing and promotion effort astronomers were surveyed on their use and awareness of the available resources, asking about their likes, dislikes and desirable features. Astronomers were queried about digital rights management (DRM) restrictions; did the ease and immediacy of remote electronic access to the content override the problems presented by DRM? Astronomers showed mixed responses to the e-book format. We need to seek continued user feedback as the Libraries' investment in online books grows.

Eurasian Reindeer Pastoralism in a Changing Climate: Indigenous Knowledge and NASA Remote Sensing

It is intended that Reindeer Mapper/EALAT will be able to provide reindeer herders with an efficient tool for managing the real-time movements and migrations of their herds through enabling improved efficiency in linking different members of the herder settlements or communities and providing real-time local, satellite or other data (e.g., ice melt in lakes and rivers, weather events), thus enabling real time adjustments to herd movements to avoid problems such as changing weather/climate conditions, freeze-thaw "lock-out" problems, or take advantage of availability of better pasturelands along migration routes. The system is being designed to incorporate local data to allow users to bring their own data into the system for analysis in addition to the data provided by the system itself. With the local information of the population, up to date environmental data and habitat characteristics, the system could generate maps depicting important features of interest for reindeer managers. One of the products derived from the planned Reindeer Mapper system will be a web-based graphic display that allows analysts to quickly pinpoint areas of interest such as those with large concentrations of reindeer and provide surrounding environmental information. The system could be automatically updated with near-real-time information such as hourly precipitation and snowfall rate and accumulation, daily surface and air temperatures, and vegetation cover conditions. The system could bring attention to the proximity of human and animal populations as part of the need for control response. A local GIS will bring these many layers together with several supporting models, showing only a straightforward graphic of the real-time situation in the field. Because the system proposed will be operating in the Internet environment, it should be virtually accessible from any network computers and wireless remote access from the field. The International Center for Reindeer Husbandry in Kautokeino, Norway, is providing regional and international coordination of and access to data sets and expertise, and will act as overall clearinghouse for EALAT information.

Telecare medical information systems (TMIS) provides rapid and convenient health care services remotely. Efficient authentication is a prerequisite to guarantee the security and privacy of patients in TMIS. Authentication is used to verify the legality of the patients and TMIS server during remote access. Very recently Islam et al. (J. Med. Syst. 38(10):135, 2014) proposed a two factor authentication protocol for TMIS using elliptic curve cryptography (ECC) to improve Xu et al.'s (J. Med. Syst. 38(1):9994, 2014) protocol. They claimed their improved protocol to be efficient and provides all security requirements. However our analysis reveals that Islam et al.'s protocol suffers from user impersonation and server impersonation attacks. Furthermore we proposed an enhanced protocol. The proposed protocol while delivering all the virtues of Islam et al.'s protocol resists all known attacks.

2012-09-01

We are currently developing network based tools for the Vacuum Tower Telescope (VTT), Tenerife which will allow to operate the telescope together with the newly developed 2D-spectrometer HELLRIDE under remote control conditions. The computational configuration can be viewed as a distributed system linking hardware components of various functionality from different locations. We have developed a communication protocol which is basically an extension of the HTTP standard. It will serve as a carrier for command- and data-transfers. The server-client software is based on Berkley-Unix sockets in a C++ programming environment. A customized CMS will allow to create browser accessible information on-the-fly. Java-based applet pages have been tested as optional user access GUI's. An access tool has been implemented to download near-realtime, web-based target information from NASA/SDO. Latency tests have been carried out at the VTT and the Swedish STT at La Palma for concept verification. Short response times indicate that under favorable network conditions remote interactive telescope handling may be possible. The scientific focus of possible future remote operations will be set on the helioseismology of the solar atmosphere, the monitoring of flares and the footpoint analysis of coronal loops and chromospheric events.

The chosen task for the remote user is an optical engineering experiment, specifically aligning a spatial filter. We instrument the physical laboratory set up in Tucson, AZ at the University of Arizona. The hardware in the spatial filter experiment is augmented by motors and cameras to allow the user to remotely control the hardware. The user interacts with a software on their computer, which communicates with a server via Internet connection to the host computer in the Optics Laboratory at the University of Arizona. Our final overall system is comprised of several subsystems. These are the optical experiment set-up, which is a spatial filter experiment; the mechanical subsystem, which interfaces the motors with the micrometers to move the optical hardware; the electrical subsystem, which allows for the electrical communications from the remote computer to the host computer to the hardware; and finally the software subsystem, which is the means by which messages are communicated throughout the system. The goal of the project is to convey as much of an in-lab experience as possible by allowing the user to directly manipulate hardware and receive visual feedback in real-time. Thus, the remote user is able to learn important concepts from this particular experiment and is able to connect theory to the physical world by actually seeing the outcome of a procedure. The latter is a learning experience that is often lost with distance learning and is one that this project hopes to provide.

Java-Library for the Access, Storage and Editing of Calibration Metadata of Optical Sensors

The standardization of the calibration of optical sensors in photogrammetry and remote sensing has been discussed for more than a decade. Projects of the German DGPF and the European EuroSDR led to the abstract International Technical Specification ISO/TS 19159-1:2014 "Calibration and validation of remote sensing imagery sensors and data - Part 1: Optical sensors". This article presents the first software interface for a read- and write-access to all metadata elements standardized in the ISO/TS 19159-1. This interface is based on an xml-schema that was automatically derived by ShapeChange from the UML-model of the Specification. The software interface serves two cases. First, the more than 300 standardized metadata elements are stored individually according to the xml-schema. Secondly, the camera manufacturers are using many administrative data that are not a part of the ISO/TS 19159-1. The new software interface provides a mechanism for input, storage, editing, and output of both types of data. Finally, an output channel towards a usual calibration protocol is provided. The interface is written in Java. The article also addresses observations made when analysing the ISO/TS 19159-1 and compiles a list of proposals for maturing the document, i.e. for an updated version of the Specification.

Telescience capability for the Sondre Stromfjord, Greenland, incoherent-scatter radar facility

SRI International (SRI) operates an upper-atmospheric research facility in Sondre Stromfjord (Sondrestrom), Greenland. In the past, the facility's remote location and limited logistical support imposed constraints on the research that could be carried out at the site. Campaigns involving multiple instruments were often constrained due to limited space, and experiments requiring coordination with other geographically separated facilities, though possible, were difficult. To provide greater access to the facility, an electronic connection between Sondrestrom and the mainland U.S.A. was established, providing access to the National Science Internet. SRI developed telescience software that sends data from the incoherent scatter radar at the Sondrestrom facility to SRI's offices in Menlo Park, California. This software uses the transmission control protocol (TCP/IP) to transmit the data in near real time between the two locations and the X window system to generate displays of the data in Menlo Park. This is in contrast to using the X window system to display data remotely across a wide-area network. Using CP to transport data over the long distance network has resulted in significantly improved network throughput and latency. While currently used to transport radar data, the telescience software is designed and intended for simultaneous use with other instruments at Sondrestrom and other facilities. Work incorporating additional instruments is currently in progress.

Proton radiotherapy is a relatively scarce treatment modality in radiation oncology, with only nine centers currently operating in the United States. Funded by Public Law 107-248, the University of Pennsylvania and the Walter Reed Army Medical Center have developed a remote proton radiation therapy solution with the goals of improving access to proton radiation therapy for Department of Defense (DoD) beneficiaries while minimizing treatment delays and time spent away from home/work (time savings of up to 3 weeks per patient). To meet both Health Insurance Portability and Accountability Act guidelines and the more stringent security restrictions imposed by the DoD, our program developed a hybrid remote proton radiation therapy solution merging a CITRIX server with a JITIC-certified (Joint Interoperability Test Command) desktop videoconferencing unit. This conduit, thoroughly tested over a period of 6 months, integrates both institutions' radiation oncology treatment planning infrastructures into a single entity for DoD patients' treatment planning and delivery. This telemedicine solution enables DoD radiation oncologists and medical physicists the ability to (1) remotely access a proton therapy treatment planning platform, (2) transfer patient plans securely to the University of Pennsylvania patient database, and (3) initiate ad-hoc point-to-point and multipoint videoconferences to dynamically optimize and validate treatment plans. Our robust and secure remote treatment planning solution grants DoD patients not only access to a state-of-the-art treatment modality, but also participation in the treatment planning process by Walter Reed Army Medical Center radiation oncologists and medical physicists. This telemedicine system has the potential to lead to a greater integration of military treatment facilities and/or satellite clinics into regional proton therapy centers.

Collaboration between dental practitioners and non-dental primary care providers has the potential to improve oral health care for people in rural and remote communities, where access to oral health services is limited. However, there is limited research on collaboration between these professional disciplines. The purpose of this paper was to explore the relationships between dental practitioners and non-dental primary care providers from rural and remote areas of Queensland and to identify strategies that could improve collaboration between these disciplines from the perspective of dental participants. Semi-structured interviews were conducted between 2013 and 2015 with visiting, local and regional dental practitioners (n = 12) who had provided dental services to patients from eight rural and remote Queensland communities that did not have a resident dentist. Participants were purposely recruited through a snow ball sampling technique. Interview data were analysed using thematic analysis with the assistance of QSR Nvivo v.10. Four major themes emerged from the data: (1) Communication between dental practitioners and rural primary care providers; (2) Relationships between dental and primary care providers; (3) Maintenance of professional dualism; (4) Strategies to improve interprofessional relationships (with subthemes: face to face meetings; utilisation of technology; oral health training for primary care providers; and having a community based oral health contact person). Participants observed that there was a lack of communication between the dental providers who saw patients from these rural communities and the primary care providers who worked in each community. This was attributed to poor communication, the high turnover of staff and the siloed behaviours of some practitioners. Visiting dental practitioners were likely to have stronger professional relationships with hospital nursing, administrative and allied health care staff who were often long term residents of the community. The findings suggest that there was little relationship between the dental personnel and primary care providers. Interprofessional collaboration between dental care providers and non-dental rural primary care providers in the rural and remote communities sampled could be improved by having regular face to face meetings between practitioners from across the health disciplines, providing oral health education to primary care providers, establishing and maintaining effective communication and referral pathways, and exploring a greater role for tele-dentistry.

AquaUsers: Improving access to remotely sensed data for non-specialists

NASA Astrophysics Data System (ADS)

Clements, Oliver; Walker, Peter; Calton, Ben; Miller, Peter

2015-04-01

In recent years more and more complex remotely sensed data have been made available to the public by national and international agencies. These data are also reprocessed by different organisations to produce secondary products that are of specific need to a community. For instance the production of chlorophyll concentration maps from ocean colour data provided by NASA for the marine community. Providing access to such data has normally been focused on simply making the data available with appropriate metadata so that domain specialists can make use of it. One area that has seen significant investment, both of time and money, has been in the production of web based data portals. Primarily these have focused on spatial data. By providing a web map visualisation users are able to quickly assess both spatial coverage and data values. Data portal improvements have been possible thanks to advancements in back end data servers such as Thredds and ncWMS as well as improvements in front-end libraries for data visualisation including OpenLayers and D3. Data portals that make use of these technological advancements have aimed at improving the access and use of data by trained scientific domain specialists. There is now a push to improve access to these systems by non-scientific domain specialists through several European Commission funded projects, including OPEC and AquaUsers. These projects have improved upon an open source web GIS portal created by Plymouth Marine Laboratory [https://github.com/pmlrsg/GISportal]. We will present the latest version of our GIS portal, discuss the designs steps taken to achieve the latest build and share user stories as to how non-domain specialists are now able to utilise the system and get benefits from remotely sensed data. A first version was produced and disseminated to end users for feedback. At this stage the end users included government advisors, fish farmers and scientific groups with no specific GIS training or knowledge. This iteration produced some pretty harsh responses. The product looked good, it seemed to have a large volume of data available but it was too difficult to get any added value from without specific training in its functionality. The feedback we gathered lead to the involvement of a user experience specialist. This was a first for both our development team and the specialist. Through a focused iteration process we created a design that would reduce the steps necessary to get meaningful output from the portal, we minimised the amount of information shown initially by using a keyword system similar to online shopping. The interface for analysing the data was greatly simplified as well, allowing easier and quicker access to time series or subsetting of data.

A medical application integrating remote 3D visualization tools to access picture archiving and communication system on mobile devices.

With computing capability and display size growing, the mobile device has been used as a tool to help clinicians view patient information and medical images anywhere and anytime. However, for direct interactive 3D visualization, which plays an important role in radiological diagnosis, the mobile device cannot provide a satisfactory quality of experience for radiologists. This paper developed a medical system that can get medical images from the picture archiving and communication system on the mobile device over the wireless network. In the proposed application, the mobile device got patient information and medical images through a proxy server connecting to the PACS server. Meanwhile, the proxy server integrated a range of 3D visualization techniques, including maximum intensity projection, multi-planar reconstruction and direct volume rendering, to providing shape, brightness, depth and location information generated from the original sectional images for radiologists. Furthermore, an algorithm that changes remote render parameters automatically to adapt to the network status was employed to improve the quality of experience. Finally, performance issues regarding the remote 3D visualization of the medical images over the wireless network of the proposed application were also discussed. The results demonstrated that this proposed medical application could provide a smooth interactive experience in the WLAN and 3G networks.

JMARS - Planetary Remote Sensing Analysis Made Even Easier

2012-12-01

Planetary remote sensing data has been collected and made public over the years from a variety of missions, but accessing this data and performing analysis on it has often been a time consuming and problematic task. JMARS (Java Mission-planning and Analysis for Remote Sensing) is a free geospatial application developed by the Mars Space Flight Facility at Arizona State University. Originally written as a misson planning tool for the THEMIS instrument on board the MARS Odyssey Spacecraft, it was released as an analysis tool to the general public in 2003. Since then it has expanded to be used for mission planning and scientific data analysis by additional NASA missions to Mars, the Moon, and Vesta and it has come to be used by scientists, researchers and students of all ages from more than 40 countries around the world. JMARS tries to save a user from the nuances of working with planetary data by providing a quick and consistent method of accessing data from various missions which can then be analyzed and compared with each other. A user can easily access hundreds of maps and millions of individual images collected by the Viking, MOC, MOLA, TES, THEMIS, HiRISE, CTX, and CRISM instruments. Users can also import their own data and work with it in an identical fashion, then optionally share that data with other users. Recent effort has been put into making JMARS easier and more consistent to use. A new toolbar makes panning and zooming easier and more intuitive, especially for systems without three button mice. Additionally, the toolbar also exposes measuring and data investigation tools that used to only be accessible in specific layers and obscure keyboard commands. The Layer Manager, which has long allowed users to reorder layers, adjust transparency, and access layer specific options, can now be optionally docked into the main view window, making it easier to work on laptops or overhead projectors. The Layer Manager can still be torn off into it's own independent window for users with multiple displays or ample screen real estate.;

The Use of Digital and Remote Communication Technologies as a Tool for Multiple Sclerosis Management: Narrative Review

Marziniak, Martin; Brichetto, Giampaolo; Feys, Peter; Meyding-Lamadé, Uta; Vernon, Karen

2018-01-01

Despite recent advances in multiple sclerosis (MS) care, many patients only infrequently access health care services, or are unable to access them easily, for reasons such as mobility restrictions, travel costs, consultation and treatment time constraints, and a lack of locally available MS expert services. Advances in mobile communications have led to the introduction of electronic health (eHealth) technologies, which are helping to improve both access to and the quality of health care services. As the Internet is now readily accessible through smart mobile devices, most people can take advantage of eHealth apps. The development of digital applications and remote communication technologies for patients with MS has increased rapidly in recent years. These apps are intended to complement traditional in-clinic approaches and can bring significant benefits to both patients with MS and health care providers (HCPs). For patients, such eHealth apps have been shown to improve outcomes and increase access to care, disease information, and support. These apps also help patients to participate actively in self-management, for example, by tracking adherence to treatment, changes in bladder and bowel habits, and activity and mood. For HCPs, MS eHealth solutions can simplify the multidisciplinary approaches needed to tailor MS management strategies to individual patients; facilitate remote monitoring of patient symptoms, adverse events, and outcomes; enable the efficient use of limited resources and clinic time; and potentially allow more timely intervention than is possible with scheduled face-to-face visits. These benefits are important because MS is a long-term, multifaceted chronic condition that requires ongoing monitoring, assessment, and management. We identified in the literature 28 eHealth solutions for patients with MS that fall within the four categories of screening and assessment, disease monitoring and self-management, treatment and rehabilitation, and advice and education. We review each solution, focusing on any clinical evidence supporting their use from prospective trials (including ASSESS MS, Deprexis, MSdialog, and the Multiple Sclerosis Performance Test) and consider the opportunities, barriers to adoption, and potential pitfalls of eHealth technologies in routine health care.

Instead of paying by cash, check, or credit cards, customers can now also use their mobile devices to pay for a wide range of services and both digital and physical goods. However, customers' security concerns are a major barrier to the broad adoption and use of mobile payments. In this paper we present the design of a secure operational model for mobile payments in which access control is based on a service-oriented architecture. A customer uses his/her mobile device to get authorization from a remote server and generate a two-dimensional barcode as the payment certificate. This payment certificate has a time limit and can be used once only. The system also provides the ability to remotely lock and disable the mobile payment service.

Visualizing and navigating through large astronomy images from a remote location with current astronomy display tools can be a frustrating experience in terms of speed and ergonomics, especially on mobile devices. In this paper, we present a high performance, versatile and robust client-server system for remote visualization and analysis of extremely large scientific images. Applications of this work include survey image quality control, interactive data query and exploration, citizen science, as well as public outreach. The proposed software is entirely open source and is designed to be generic and applicable to a variety of datasets. It provides access to floating point data at terabyte scales, with the ability to precisely adjust image settings in real-time. The proposed clients are light-weight, platform-independent web applications built on standard HTML5 web technologies and compatible with both touch and mouse-based devices. We put the system to the test and assess the performance of the system and show that a single server can comfortably handle more than a hundred simultaneous users accessing full precision 32 bit astronomy data.

Innovative Medical Technology, Health Technology Assessment, and Health Policy: The Case of Remote Patient Monitoring of Cardiac Implantable Electronic Devices in South Korea.

PubMed

Lee, Sang-Soo; Salole, Eugene

2017-01-01

In many developed countries with universal coverage healthcare systems, payers require new medical technologies to be assessed as safe, effective, and cost-effective through health technology assessment (HTA) before approval for reimbursement coverage and market access. However, in some cases, HTA is not the sole criterion for decision-making and other factors override the evidence. Remote patient monitoring (RPM) for cardiac implantable electronic devices, a novel technology recognized as safe, effective, and cost-effective, and the standard of care in many countries, is prohibited in South Korea. This peculiar situation is apparently due to deficiencies in healthcare policy and the delivery system and also to poor engagement between stakeholders. We propose that a higher level of engagement and trust between stakeholders needs to be developed, and healthcare providers should be involved in the early development of health policy, so that unnecessary barriers to access to useful medical technology are corrected, thereby allowing Koreans to enjoy the benefits available in other developed countries.

Augmenting the access grid using augmented reality

NASA Astrophysics Data System (ADS)

Li, Ying

2012-01-01

The Access Grid (AG) targets an advanced collaboration environment, with which multi-party group of people from remote sites can collaborate over high-performance networks. However, current AG still employs VIC (Video Conferencing Tool) to offer only pure video for remote communication, while most AG users expect to collaboratively refer and manipulate the 3D geometric models of grid services' results in live videos of AG session. Augmented Reality (AR) technique can overcome the deficiencies with its characteristics of combining virtual and real, real-time interaction and 3D registration, so it is necessary for AG to utilize AR to better assist the advanced collaboration environment. This paper introduces an effort to augment the AG by adding support for AR capability, which is encapsulated in the node service infrastructure, named as Augmented Reality Service (ARS). The ARS can merge the 3D geometric models of grid services' results and real video scene of AG into one AR environment, and provide the opportunity for distributed AG users to interactively and collaboratively participate in the AR environment with better experience.

Measuring and Monitoring Long Term Disaster Recovery Using Remote Sensing: A Case Study of Post Katrina New Orleans

NASA Astrophysics Data System (ADS)

Archer, Reginald S.

This research focuses on measuring and monitoring long term recovery progress from the impacts of Hurricane Katrina on New Orleans, LA. Remote sensing has frequently been used for emergency response and damage assessment after natural disasters. However, techniques for analysis of long term disaster recovery using remote sensing have not been widely explored. With increased availability and lower costs, remote sensing offers an objective perspective, systematic and repeatable analysis, and provides a substitute to multiple site visits. In addition, remote sensing allows access to large geographical areas and areas where ground access may be disrupted, restricted or denied. This dissertation addressed the primary difficulties involved in the development of change detection methods capable of detecting changes experienced by disaster recovery indicators. Maximum likelihood classification and post-classification change detection were applied to multi-temporal high resolution aerial images to quantitatively measure the progress of recovery. Images were classified to automatically identify disaster recovery indicators and exploit the indicators that are visible within each image. The spectral analysis demonstrated that employing maximum likelihood classification to high resolution true color aerial images performed adequately and provided a good indication of spectral pattern recognition, despite the limited spectral information. Applying the change detection to the classified images was effective for determining the temporal trajectory of indicators categorized as blue tarps, FEMA trailers, houses, vegetation, bare earth and pavement. The results of the post classification change detection revealed a dominant change trajectory from bluetarp to house, as damaged houses became permanently repaired. Specifically, the level of activity of blue tarps, housing, vegetation, FEMA trailers (temporary housing) pavement and bare earth were derived from aerial image processing to measure and monitor the progress of recovery. Trajectories of recovery for each individual indicator were examined to provide a better understanding of activity during reconstruction. A collection of spatial metrics was explored in order to identify spatial patterns and characterize classes in terms of patches of pixels. One of the key findings of the spatial analysis is that patch shapes were more complex in the presence of debris and damaged or destroyed buildings. The combination of spectral, temporal, and spatial analysis provided a satisfactory, though limited, solution to the question of whether remote sensing alone, can be used to quantitatively assess and monitor the progress of long term recovery following a major disaster. The research described in this dissertation provided a detailed illustration of the level of activity experienced by different recovery indicators during the long term recovery process. It also addressed the primary difficulties involved in the development of change detection methods capable of detecting changes experienced by disaster recovery indicators identified from classified high resolution true color aerial imagery. The results produced in this research demonstrate that the observed trajectories for actual indicators of recovery indicate different levels of recovery activity even within the same community. The level of activity of the long term reconstruction phase observed in the Kates model is not consistent with the level of activity of key recovery indicators in the Lower 9th Ward during the same period. Used in the proper context, these methods and results provide decision making information for determining resources.

With the rapid growth of genome sequencing projects, genome browser is becoming indispensable, not only as a visualization system but also as an interactive platform to support open data access and collaborative work. Thus a customizable genome browser framework with rich functions and flexible configuration is needed to facilitate various genome research projects. Based on next-generation web technologies, we have developed a general-purpose genome browser framework ABrowse which provides interactive browsing experience, open data access and collaborative work support. By supporting Google-map-like smooth navigation, ABrowse offers end users highly interactive browsing experience. To facilitate further data analysis, multiple data access approaches are supported for external platforms to retrieve data from ABrowse. To promote collaborative work, an online user-space is provided for end users to create, store and share comments, annotations and landmarks. For data providers, ABrowse is highly customizable and configurable. The framework provides a set of utilities to import annotation data conveniently. To build ABrowse on existing annotation databases, data providers could specify SQL statements according to database schema. And customized pages for detailed information display of annotation entries could be easily plugged in. For developers, new drawing strategies could be integrated into ABrowse for new types of annotation data. In addition, standard web service is provided for data retrieval remotely, providing underlying machine-oriented programming interface for open data access. ABrowse framework is valuable for end users, data providers and developers by providing rich user functions and flexible customization approaches. The source code is published under GNU Lesser General Public License v3.0 and is accessible at http://www.abrowse.org/. To demonstrate all the features of ABrowse, a live demo for Arabidopsis thaliana genome has been built at http://arabidopsis.cbi.edu.cn/.

Rationing is a reality in rural physiotherapy: a qualitative exploration of service level decision-making.

Deciding what health services are provided is a key consideration in delivering appropriate and accessible health care for rural and remote populations. Despite residents of rural communities experiencing poorer health outcomes and exhibiting higher health need, workforce shortages and maldistribution mean that rural communities do not have access to the range of services available in metropolitan centres. Where demand exceeds available resources, decisions about resource allocation are required. A qualitative approach enabled the researchers to explore participant perspectives about decisions informing rural physiotherapy service provision. Stakeholder perspectives were obtained through surveys and in-depth interviews. A system theory-case study heuristic provided a framework for exploration across sites within the investigation area: a large area of one Australian state with a mix of rural, regional and remote communities. Thirty-nine surveys were received from participants in eleven communities. Nineteen in-depth interviews were conducted with physiotherapist and key decision-makers. Increasing demand, organisational priorities, fiscal austerity measures and workforce challenges were identified as factors influencing both decision-making and service provision. Rationing of physiotherapy services was common to all sites of this study. Rationing of services, more commonly expressed as service prioritisation, was more evident in responses of public sector physiotherapy participants compared to private physiotherapists. However, private physiotherapists in rural areas reported capacity limits, including expertise, space and affordability that constrained service provision. The imbalance between increasing service demands and limited physiotherapy capacity meant making choices was inevitable. Decreased community access to local physiotherapy services and increased workforce stress, a key determinant of retention, are two results of such choices or decisions. Decreased access was particularly evident for adults and children requiring neurological rehabilitation and for people requiring post-acute physiotherapy. It should not be presumed that rural private physiotherapy providers will cover service gaps that may emerge from changes to public sector service provision. Clinician preference combines with capacity limits and the imperative of financial viability to negate such assumptions. This study provides insight into rural physiotherapy service provision not usually evident and can be used to inform health service planning and decision-making and education of current and future rural physiotherapists.

Ozdogan, M.; Serrat-Capdevila, A.; Anderson, M. C.

2017-12-01

Despite increasing scarcity of freshwater resources, there is dearth of spatially explicit information on irrigation water consumption through evapotranspiration, particularly in semi-arid and arid geographies. Remote sensing, either alone or in combination with ground surveys, is increasingly being used for irrigation water management by quantifying evaporative losses at the farm level. Increased availability of observations, sophisticated algorithms, and access to cloud-based computing is also helping this effort. This presentation will focus on crop-specific evapotranspiration estimates at the farm level derived from remote sensing in a number of water-scarce regions of the world. The work is part of a larger effort to quantify irrigation water use and improve use efficiencies associated with several World Bank projects. Examples will be drawn from India, where groundwater based irrigation withdrawals are monitored with the help of crop type mapping and evapotranspiration estimates from remote sensing. Another example will be provided from a northern irrigation district in Mexico, where remote sensing is used for detailed water accounting at the farm level. These locations exemplify the success stories in irrigation water management with the help of remote sensing with the hope that spatially disaggregated information on evapotranspiration can be used as inputs for various water management decisions as well as for better water allocation strategies in many other water scarce regions.

A Secure Mobile-Based Authentication System for e-Banking

Rifà-Pous, Helena

Financial information is extremely sensitive. Hence, electronic banking must provide a robust system to authenticate its customers and let them access their data remotely. On the other hand, such system must be usable, affordable, and portable. We propose a challenge-response based one-time password (OTP) scheme that uses symmetric cryptography in combination with a hardware security module. The proposed protocol safeguards passwords from keyloggers and phishing attacks. Besides, this solution provides convenient mobility for users who want to bank online anytime and anywhere, not just from their own trusted computers.

Design and Execution of make-like, distributed Analyses based on Spotify’s Pipelining Package Luigi

Erdmann, M.; Fischer, B.; Fischer, R.; Rieger, M.

2017-10-01

In high-energy particle physics, workflow management systems are primarily used as tailored solutions in dedicated areas such as Monte Carlo production. However, physicists performing data analyses are usually required to steer their individual workflows manually which is time-consuming and often leads to undocumented relations between particular workloads. We present a generic analysis design pattern that copes with the sophisticated demands of end-to-end HEP analyses and provides a make-like execution system. It is based on the open-source pipelining package Luigi which was developed at Spotify and enables the definition of arbitrary workloads, so-called Tasks, and the dependencies between them in a lightweight and scalable structure. Further features are multi-user support, automated dependency resolution and error handling, central scheduling, and status visualization in the web. In addition to already built-in features for remote jobs and file systems like Hadoop and HDFS, we added support for WLCG infrastructure such as LSF and CREAM job submission, as well as remote file access through the Grid File Access Library. Furthermore, we implemented automated resubmission functionality, software sandboxing, and a command line interface with auto-completion for a convenient working environment. For the implementation of a t \\overline{{{t}}} H cross section measurement, we created a generic Python interface that provides programmatic access to all external information such as datasets, physics processes, statistical models, and additional files and values. In summary, the setup enables the execution of the entire analysis in a parallelized and distributed fashion with a single command.

Data Access Services that Make Remote Sensing Data Easier to Use

NASA Technical Reports Server (NTRS)

Lynnes, Christopher

2010-01-01

This slide presentation reviews some of the processes that NASA uses to make the remote sensing data easy to use over the World Wide Web. This work involves much research into data formats, geolocation structures and quality indicators, often to be followed by coding a preprocessing program. Only then are the data usable within the analysis tool of choice. The Goddard Earth Sciences Data and Information Services Center is deploying a variety of data access services that are designed to dramatically shorten the time consumed in the data preparation step. On-the-fly conversion to the standard network Common Data Form (netCDF) format with Climate-Forecast (CF) conventions imposes a standard coordinate system framework that makes data instantly readable through several tools, such as the Integrated Data Viewer, Gridded Analysis and Display System, Panoply and Ferret. A similar benefit is achieved by serving data through the Open Source Project for a Network Data Access Protocol (OPeNDAP), which also provides subsetting. The Data Quality Screening Service goes a step further in filtering out data points based on quality control flags, based on science team recommendations or user-specified criteria. Further still is the Giovanni online analysis system which goes beyond handling formatting and quality to provide visualization and basic statistics of the data. This general approach of automating the preparation steps has the important added benefit of enabling use of the data by non-human users (i.e., computer programs), which often make sub-optimal use of the available data due to the need to hard-code data preparation on the client side.

Remotely Sensed Imagery from USGS: Update on Products and Portals

NASA Astrophysics Data System (ADS)

Lamb, R.; Lemig, K.

2016-12-01

The USGS Earth Resources Observation and Science (EROS) Center has recently implemented a number of additions and changes to its existing suite of products and user access systems. Together, these changes will enhance the accessibility, breadth, and usability of the remotely sensed image products and delivery mechanisms available from USGS. As of late 2016, several new image products are now available for public download at no charge from USGS/EROS Center. These new products include: (1) global Level 1T (precision terrain-corrected) products from Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), provided via NASA's Land Processes Distributed Active Archive Center (LP DAAC); and (2) Sentinel-2 Multispectral Instrument (MSI) products, available through a collaborative effort with the European Space Agency (ESA). Other new products are also planned to become available soon. In an effort to enable future scientific analysis of the full 40+ year Landsat archive, the USGS also introduced a new "Collection Management" strategy for all Landsat Level 1 products. This new archive and access schema involves quality-based tier designations that will support future time series analysis of the historic Landsat archive at the pixel level. Along with the quality tier designations, the USGS has also implemented a number of other Level 1 product improvements to support Landsat science applications, including: enhanced metadata, improved geometric processing, refined quality assessment information, and angle coefficient files. The full USGS Landsat archive is now being reprocessed in accordance with the new `Collection 1' specifications. Several USGS data access and visualization systems have also seen major upgrades. These user interfaces include a new version of the USGS LandsatLook Viewer which was released in Fall 2017 to provide enhanced functionality and Sentinel-2 visualization and access support. A beta release of the USGS Global Visualization Tool ("GloVis Next") was also released in Fall 2017, with many new features including data visualization at full resolution. The USGS also introduced a time-enabled web mapping service (WMS) to support time-based access to the existing LandsatLook "natural color" full-resolution browse image services.

U.S. Government Open Internet Access to Sub-meter Satellite Data

The National Geospatial-Intelligence Agency (NGA) has contracted United States commercial remote sensing companies GeoEye and Digital Globe to provide very high resolution commercial quality satellite imagery to federal/state government agencies and those projects/people who support government interests. Under NextView contract terms, those engaged in official government programs/projects can gain online access to NGA's vast global archive. Additionally, data from vendor's archives of IKONOS-2 (IK-2), OrbView-3 (OB-3), GeoEye-1 (GE-1), QuickBird-1 (QB-1), WorldView-1 (WV-1), and WorldView-2 (WV-2), sensors can also be requested under these agreements. We report here the current extent of this archive, how to gain access, and the applications of these data by Earth science investigators to improve discoverability and community use of these data. Satellite commercial quality imagery (CQI) at very high resolution (< 1 m) (here after referred to as CQI) over the past decade has become an important data source to U.S. federal, state, and local governments for many different purposes. The rapid growth of free global CQI data has been slow to disseminate to NASA Earth Science community and programs such as the Land-Cover Land-Use Change (LCLUC) program which sees potential benefit from unprecedented access. This article evolved from a workshop held on February 23rd, 2012 between representatives from NGA, NASA, and NASA LCLUC Scientists discussion on how to extend this resource to a broader license approved community. Many investigators are unaware of NGA's archive availability or find it difficult to access CQI data from NGA. Results of studies, both quality and breadth, could be improved with CQI data by combining them with other moderate to coarse resolution passive optical Earth observation remote sensing satellites, or with RADAR or LiDAR instruments to better understand Earth system dynamics at the scale of human activities. We provide the evolution of this effort, a guide for qualified user access, and describe current to potential use of these data in earth science.

Using NASA's Giovanni Web Portal to Access and Visualize Satellite-Based Earth Science Data in the Classroom

One of the biggest obstacles for the average Earth science student today is locating and obtaining satellite- based remote sensing datasets in a format that is accessible and optimal for their data analysis needs. At the Goddard Earth Sciences Data and Information Services Center (GES-DISC) alone, on the order of hundreds of Terabytes of data are available for distribution to scientists, students and the general public. The single biggest and time-consuming hurdle for most students when they begin their study of the various datasets is how to slog through this mountain of data to arrive at a properly sub-setted and manageable dataset to answer their science question(s). The GES DISC provides a number of tools for data access and visualization, including the Google-like Mirador search engine and the powerful GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure (Giovanni) web interface. Giovanni provides a simple way to visualize, analyze and access vast amounts of satellite-based Earth science data. Giovanni's features and practical examples of its use will be demonstrated, with an emphasis on how satellite remote sensing can help students understand recent events in the atmosphere and biosphere. Giovanni is actually a series of sixteen similar web-based data interfaces, each of which covers a single satellite dataset (such as TRMM, TOMS, OMI, AIRS, MLS, HALOE, etc.) or a group of related datasets (such as MODIS and MISR for aerosols, SeaWIFS and MODIS for ocean color, and the suite of A-Train observations co-located along the CloudSat orbital path). Recently, ground-based datasets have been included in Giovanni, including the Northern Eurasian Earth Science Partnership Initiative (NEESPI), and EPA fine particulate matter (PM2.5) for air quality. Model data such as the Goddard GOCART model and MERRA meteorological reanalyses (in process) are being increasingly incorporated into Giovanni to facilitate model- data intercomparison. A full suite of data analysis and visualization tools is also available within Giovanni. The GES DISC is currently developing a systematic series of training modules for Earth science satellite data, associated with our development of additional datasets and data visualization tools for Giovanni. Training sessions will include an overview of the Earth science datasets archived at Goddard, an overview of terms and techniques associated with satellite remote sensing, dataset-specific issues, an overview of Giovanni functionality, and a series of examples of how data can be readily accessed and visualized.

The role of continuous monitoring in a 24/7 telecardiology consultation service--a feasibility study.

PubMed

Nikus, Kjell; Lähteenmäki, Jaakko; Lehto, Pasi; Eskola, Markku

2009-01-01

Today's coronary care unit patients include those with complicated and uncomplicated myocardial infarction, decompensated heart failure and frank cardiogenic shock, severe valvular heart disease, high-grade conduction disturbances, and incessant ventricular arrhythmias. Increasingly in modern medicine, these conditions are not seen in isolation but rather in connection with a series of additional medical comorbidities. Increased life expectancy results in an increase in the prevalence of chronic cardiovascular diseases and an increased demand for health care services. Telemedicine is the provision of health care services, through the use of information and communication technology, in situations where the health care professional and the patient, or 2 health care professionals, are not in the same location. It involves the secure transmission of medical data and information, through text, sound, images, or other forms needed for the prevention, diagnosis, treatment, and follow-up of a patient. Telecardiology is one of the oldest applications in telemedicine and has been largely applied during the last 10 to 20 years. This study evaluated the feasibility of remote surveillance of coronary care unit and cardiology ward patient monitoring data by a "telecardiologist" with access to electronic health care record data and digitally stored 12-lead electrocardiograms. The remote access to the hospital intranet proved to be technically feasible. Also, the server applications used over the remote connection proved to be reliable and showed robustness against network performance variations. Extending remote patient surveillance to other hospitals is possible, provided that similar electrocardiogram and electronic health care record applications are available and a remote access can be arranged to them. However, the usability from cardiologist's perspective may be degraded if connecting with multiple applications and hospital networks is needed. The study indicated potential for speeding up the diagnostic and therapeutic processes in the hospital, although the study was limited in that the telecardiologist played a passive role and did not acutely impact patient care. In the future, the system could be expanded to surveillance of smaller hospitals. Telemedicine has the potential to aid in solving the conflict between aging of population, rise in the demand for critical care services, and shortage of professional personnel. This might, however, require a more active remote surveillance than the one tested in this study. Privacy- and security-related aspects are major components of building trust and confidence in telemedicine systems. In telecardiology, the real-time interactive telemedicine model with 24/7 service has potential superior performance compared with a store-and-forward telemedicine model.

Smartphone-based devices and applications (SBDAs) with cost effectiveness and remote sensing are the most promising and effective means of delivering mobile healthcare (mHealthcare). Several SBDAs have been commercialized for the personalized monitoring and/or management of basic physiological parameters, such as blood pressure, weight, body analysis, pulse rate, electrocardiograph, blood glucose, blood glucose saturation, sleeping and physical activity. With advances in Bluetooth technology, software, cloud computing and remote sensing, SBDAs provide real-time on-site analysis and telemedicine opportunities in remote areas. This scenario is of utmost importance for developing countries, where the number of smartphone users is about 70% of 6.8 billion cell phone subscribers worldwide with limited access to basic healthcare service. The technology platform facilitates patient-doctor communication and the patients to effectively manage and keep track of their medical conditions. Besides tremendous healthcare cost savings, SBDAs are very critical for the monitoring and effective management of emerging epidemics and food contamination outbreaks. The next decade will witness pioneering advances and increasing applications of SBDAs in this exponentially growing field of mHealthcare. This article provides a critical review of commercial SBDAs that are being widely used for personalized healthcare monitoring and management. PMID:26852680

The availability and accessibility of remote sensing (RS) data, cloud processing platforms and provided information products and services has increased the size and diversity of the RS user community. This development also generates a need for validation approaches to assess data quality. Validation approaches employ quality criteria in their assessment. Data Quality (DQ) dimensions as the basis for quality criteria have been deeply investigated in the database area and in the remote sensing domain. Several standards exist within the RS domain but a general classification - established for databases - has been adapted only recently. For an easier identification of research opportunities, a better understanding is required how quality criteria are employed in the RS lifecycle. Therefore, this research investigates how quality criteria support decisions that guide the RS lifecycle and how they relate to the measured DQ dimensions. Subsequently follows an overview of the relevant standards in the RS domain that is matched to the RS lifecycle. Conclusively, the required research needs are identified that would enable a complete understanding of the interrelationships between the RS lifecycle, the data sources and the DQ dimensions, an understanding that would be very valuable for designing validation approaches in RS.

A Multi-Institutional Big Data Collaboration to Estimate Long Term Terrestrial Net Carbon Uptake from Remote Sensing and Hydrological Modeling

Recent aircraft measurements from scattered records have shown long-term, global, seasonal photosynthetic CO2 uptake over land accelerating over the past 50 years. The successful launch of the sun-synchronous Orbiting Carbon Observatory 2 (OCO-2) on July 2, 2014 is expected to provide global, high spatial and spectral resolution datasets of vertical CO2 concentrations with surface spectral resolutions capable of yielding accurate CO2 flux profiles. It is unclear whether the biosphere will continue to act as a sink for anthropogenic CO2 loading of the atmosphere. Since current climate models with detailed terrestrial ecosystems are unable to simulate the observed increase in net ecosystem production (NEP), we will conduct assimilation studies with the derived CO2 fluxes in the GSFC Land Information System hydrological model to validate the generated NEP uptake. Further, we plan to use the OCO-2 CO2 concentrations to train a neural network to enable the calculation of long term trends from a decade of AIRS CO2 concentration data to produce regional NEP. To address this important Big Data science issue, a multi-institutional collaboration was formed to leverage their combined resources and the expertise of the researchers at the NASA GSFC, the Lamont Doherty Earth Observatory and UMBC. We will employ a high speed 10Gb network to connect the collaborating researchers and provide them with remote access to dedicated computational hybrid multicore resources at UMBC, as well as access to an archive containing more than a decade of readily accessible continuous daily gridded AIRS data and ten years of daily MODIS data for each September. The status of the following research efforts is planned to be presented; (i) acquisition and processing of the expected CO2 profile data from OCO-2 for two test sites, a low latitude region over the Amazon and a Boral forest at high latitude, (ii) initial impact of 3-D data assimilation of CO2 fluxes with the advanced Goddard LIS hydrological surface model, (iii) preliminary results in training AIRS CO2 data. In addition, early results of innovative exploration on quantum annealing optimization for 3-D data assimilation, image registration and a Hopfield neural network for training the AIRS CO2 spectral data through UMBC remote access to the D-Wave system in Vancouver, CA, will be introduced.

Telepsychiatry was introduced in the early 1950's for the provision of mental health services from a distance. In 1990 the progress made in telecommunications technologies caused a significant expansion in telepsychiatry services. It can refer to store and forward technologies, interactive technologies, remote monitoring technologies and it is applied to contribute to the lift of restrictions placed on providing mental health services. Restrictions may exist due to geographic isolation, lack of specialized services, high cost of moving patients etc. The positive cost-benefit analysis and the reliability of diagnosis and efficacy of interventions through telepsychiatry have been documented in various research papers referring to a wide range of contexts such as prisons, remote areas, general and psychiatric hospitals. Since 2003 the Mobile Mental Health Unit of South- Eastern (SE) Cyclades has been using videoconferencing in order to provide mental health services in thirteen islands. This area shares many of the characteristics of remote areas such as residential dispersion, lack of mental health services and frequent lack of access to services in urban centers. Telepsychiatry in conjunction with physical presence of professionals was launched by the Mobile Mental Health Unit in order to provide assistance to the evaluation of patients, to therapeutic interventions, to medicine prescription, to crisis intervention, to psychoeducation of patients and their families and to the implementation of educational and administrative activities . The use of existing technology in combination with the development of human resources has enabled continuity of care, crisis intervention and avoidance of involuntary hospitalization for a significant number of persons. Moreover, it has improved cooperation and coordination between the interdisciplinary team and local authorities and agencies. When professionals located in different parts are collaborating via telepsychiatry it is necessary to ensure that they have immediate and simultaneous access to data concerning the patient. This need is served by the electronic medical record that facilitates access to patient records, improves the quality of care, reduces the probability of making wrong decisions and contributes to the promotion of research and service evaluation. KLIMAKA's electronic medical record contains more than ten thousand cases of which 4544 are related to individuals served by the Mobile Mental Health Unit during the years 2003-2010. This article presents the basic functions and parameters of the electronic medical record, the applications of telepsychiatry in the whole range of services provided by the scientific staff and provides information on how human and technology resources are distributed to the branches of the Mobile Mental Health Unit of SE Cyclades.

Development of a generic system for real-time data access and remote control of multiple in-situ water quality monitoring instruments

NASA Astrophysics Data System (ADS)

Wright, S. A.; Bennett, G. E.; Andrews, T.; Melis, T. S.; Topping, D. J.

Currently, in-situ monitoring of water quality parameters (e.g. water temperature, conductivity, turbidity) in the Colorado River ecosystem typically consists of deploying instruments in the river, retrieving them at a later date, downloading the datalogger, then examining the data; an arduous process in the remote settings of Grand Canyon. Under this protocol, data is not available real-time and there is no way to detect problems with the instrumentation until after retrieval. The next obvious stage in the development of in-situ monitoring in Grand Canyon was the advent of one-way telemetry, i.e. streaming data in real-time from the instrument to the office and/or the world-wide-web. This protocol allows for real-time access to data and the identification of instrumentation problems, but still requires a site visit to address instrument malfunctions, i.e. the user does not have the ability to remotely control the instrument. At some field sites, such as the Colorado River in Grand Canyon, site visitation is restricted by remoteness and lack of traditional access routes (i.e. roads). Even at less remote sites, it may still be desirable to have two-way communication with instruments in order to, for example, diagnose and potentially fix instrumentation problems, change sampling parameters to save battery power, etc., without having to visit the site. To this end, the U.S. Geological Survey, Grand Canyon Monitoring and Research Center, is currently developing and testing a high-speed, two-way communication system that allows for real-time data access and remote control of instrumentation. The approach tested relies on internet access and may be especially useful in areas where land-line or cellular connections are unavailable. The system is composed of off-the-shelf products, uses a commercial broadband satellite service, and is designed in a generic way such that any instrument that communicates through RS-232 communication (i.e. a serial port) is compatible with the system. We are currently testing the system at two sites on the Colorado River in Grand Canyon and at one critical monitoring site on the Paria River where we have deployed suites of instruments for monitoring flow, sediment concentration, temperature, and conductivity. One aspect of the system that may be particularly useful for ecohydrological applications is the ability to remotely control on-site pump samplers, which allows for the collection of a water sample by the press of a button in the office.

Astronomy in grades K-12 is traditionally taught (if at all) using textbooks and a few simple hands-on activities. Teachers are generally not trained in observational astronomy techniques and are unfamiliar with the most basic astronomical concepts. In addition, most students, by High School graduation, will never have even looked through the eyepiece of a telescope. The problem becomes even more challenging in inner cities, remote rural areas and low socioeconomic communities where educational emphasis on topics in astronomy as well as access to observing facilities is limited or non existent. Access to most optical telescope facilities is limited to monthly observing nights that cater to a small percentage of the general public living near the observatory. Even here, the observing experience is a one-time event detached from the process of scientific enquiry and sustained educational application. Additionally, a number of large, "research grade" observatory facilities are largely unused, partially due to the slow creep of light pollution around the facilities as well as the development of newer, more capable telescopes. Though cutting edge science is often no longer possible at these sights, real research opportunities in astronomy remain numerous for these facilities as educational tools. The possibility now exists to establish a network of research grade telescopes, no longer useful to the professional astronomical community, that can be made accessible through classrooms, after school, and community based programs all across the country through existing IT technologies and applications. These telescopes could provide unparalleled research and educational opportunities for a broad spectrum of students and turns underutilized observatory facilities into valuable, state-of-the-art teaching centers. The NASA sponsored Telescopes In Education project has been wildly successful in engaging the K-12 education community in real-time, hands-on, interactive astronomy activities. Hundreds of schools in the US, Australia, Canada, England, and Japan have participated in the TIE program, remotely controlling the 24-inch telescope at the Mount Wilson Observatory from their classrooms. In recent years, several (approximately 20 to date) other telescopes have been, or are in the process of being, outfitted for remote use as TIE affiliates. Global TIE integrates these telescopes seamlessly into one virtual observatory and provides the services required to operate this facility, including a scheduling service, tools for data manipulation, an online proposal review environment, an online "Virtual TIE Student Ap J" for publication of results, and access to related educational materials provided by the TIE community. This presentation describes the Global TIE Observatory data and organizational systems and details the technology, partnerships, operational capabilities, science applications, and learning opportunities that this powerful virtual observatory network will provide.

Today, users access information and rich media from anywhere using the web browser on their desktop computers, tablets or smartphones. But the web evolves beyond media delivery. Interactive graphics applications like visualization or gaming become feasible as browsers advance in the functionality they provide. However, to deliver large-scale visualization to thin clients like mobile devices, a dedicated server component is necessary. Ideally, the client runs directly within the browser the user is accustomed to, requiring no installation of a plugin or native application. In this paper, we present the state-of-the-art of technologies which enable plugin free remote rendering in the browser. Further, we describe a remote visualization system unifying these technologies. The system transfers rendering results to the client as images or as a video stream. We utilize the upcoming World Wide Web Consortium (W3C) conform Web Real-Time Communication (WebRTC) standard, and the Native Client (NaCl) technology built into Chrome, to deliver video with low latency.

An in Situ Technique for Elemental Analysis of Lunar Surfaces

An in situ analytical technique that can remotely determine the elemental constituents of solids has been demonstrated. Laser-Induced Breakdown Spectroscopy (LIBS) is a form of atomic emission spectroscopy in which a powerful laser pulse is focused on a solid to generate a laser spark, or microplasma. Material in the plasma is vaporized, and the resulting atoms are excited to emit light. The light is spectrally resolved to identify the emitting species. LIBS is a simple technique that can be automated for inclusion aboard a remotely operated vehicle. Since only optical access to a sample is required, areas inaccessible to a rover can be analyzed remotely. A single laser spark both vaporizes and excites the sample so that near real-time analysis (a few minutes) is possible. This technique provides simultaneous multielement detection and has good sensitivity for many elements. LIBS also eliminates the need for sample retrieval and preparation preventing possible sample contamination. These qualities make the LIBS technique uniquely suited for use in the lunar environment.

Astronomy is being transformed by the vast quantities of data, models, and simulations that are becoming available to astronomers at an ever-accelerating rate. The U.S. Virtual Astronomical Observatory (VAO) has been funded to provide an operational facility that is intended to be a resource for discovery and access of data, and to provide science services that use these data. Over the course of the past year, the VAO has been developing and releasing for community use five science tools: 1) "Iris", for dynamically building and analyzing spectral energy distributions, 2) a web-based data discovery tool that allows astronomers to identify and retrieve catalog, image, and spectral data on sources of interest, 3) a scalable cross-comparison service that allows astronomers to conduct pair-wise positional matches between very large catalogs stored remotely as well as between remote and local catalogs, 4) time series tools that allow astronomers to compute periodograms of the public data held at the NASA Star and Exoplanet Database (NStED) and the Harvard Time Series Center, and 5) A VO-aware release of the Image Reduction and Analysis Facility (IRAF) that provides transparent access to VO-available data collections and is SAMP-enabled, so that IRAF users can easily use tools such as Aladin and Topcat in conjuction with IRAF tasks. Additional VAO services will be built to make it easy for researchers to provide access to their data in VO-compliant ways, to build VO-enabled custom applications in Python, and to respond generally to the growing size and complexity of astronomy data.

Mobile Web and Accessibility

NASA Astrophysics Data System (ADS)

Hori, Masahiro; Kato, Takashi

While focusing on the human-computer interaction side of the Web content delivery, this article discusses problems and prospects of the mobile Web and Web accessibility in terms of what lessons and experiences we have gained from Web accessibility and what they can say about the mobile Web. One aim is to draw particular attention to the importance of explicitly distinguishing between perceptual and cognitive aspects of the users’ interactions with the Web. Another is to emphasize the increased importance of scenario-based evaluation and remote testing for the mobile Web where the limited screen space and a variety of environmental factors of mobile use are critical design issues. A newly devised inspection type of evaluation method that focuses on the perceptual-cognitive distinction of accessibility and usability issues is presented as a viable means of scenario-based, remote testing for the Web.

The Environmental Molecular Sciences Laboratory (EMSL) in Richland, Washington, is the home of a research facility setup by the United States Department of Energy (DOE). The facility is atypical because it houses over 100 cutting-edge research systems for the use of researchers all over the United States and the world. Access to the lab is requested through a peer-review proposal process and the scientists who use the facility are generally referred to as ‘users’. There are six main research facilities housed in EMSL, all of which host visiting researchers. Several of these facilities also participate in the EMSL Collaboratory, amore » remote access capability supported by EMSL operations funds. Of these, the High-Field Magnetic Resonance Facility (HFMRF) and Molecular Science Computing Facility (MSCF) have a significant number of their users performing remote work. The HFMRF in EMSL currently houses 12 NMR spectrometers that range in magnet field strength from 7.05T to 21.1T. Staff associated with the NMR facility offers scientific expertise in the areas of structural biology, solid-state materials/catalyst characterization, and magnetic resonance imaging (MRI) techniques. The way in which the HFMRF operates, with a high level of dedication to remote operation across the full suite of High-Field NMR spectrometers, has earned it the name “Virtual NMR Facility”. This review will focus on the operational aspects of remote research done in the High-Field Magnetic Resonance Facility and the computer tools that make remote experiments possible.« less

Australians living in rural and remote communities experience relatively poor health status in comparison to the wider Australian population (Med J Aust 185:37-38, 2006). This can be attributed in part to issues of access to health services arising from difficulties in recruiting and retaining health professionals in these areas. The Rural Health Professionals Program is an initiative designed to increase the number of allied health and nursing professionals in rural and remote Australia by providing case managed recruitment and retention support services. This paper reports on early analysis of available programme data to build knowledge of factors related to the recruitment and distribution of health professionals in rural and remote Australia. Administrative programme data were collected monthly from 349 health professionals over the first 13 months of programme operation. These data were collated and quantitative analysis was conducted using SPSS software. Sixty-nine percent of recruits were women, and recruits had a mean age of 32.85 (SD = 10.92). Sixty percent of recruits were domestically trained, and the top two professions recruited were nurses (29%) and physiotherapists (21%). Eighty-seven percent were recruited to regional areas, with the remaining 13% recruited to remote areas. Among reasons for interest in the programme, financial support factors were most commonly cited by recruits (51%). Recruitment to a remote location was associated with being domestically trained, having previously lived in a rural or remote location, being a nurse (as opposed to an allied health professional) and older age. The findings provide early support for a case managed recruitment programme to improve distribution of health professionals, and some directions for future marketing and promotion of the programme. It is recommended that an outcome evaluation be conducted to determine the impact of the programme on recruitment and distribution outcomes. The findings herein begin to address gaps in the literature relating to the effectiveness of interventions to improve the distribution of health professionals. While this provides some preliminary indication that case managed recruitment and retention programmes have capacity to improve distribution, further research and evaluation is required to confirm the impact of the programme on retention.

This paper describes the application of wireless local area network (LAN) simulation modeling methods to the hybrid LAN architecture designed for supporting crew-computing tools aboard the International Space Station (ISS). These crew-computing tools, such as wearable computers and portable advisory systems, will provide crew members with real-time vehicle and payload status information and access to digital technical and scientific libraries, significantly enhancing human capabilities in space. A wireless network, therefore, will provide wearable computer and remote instruments with the high performance computational power needed by next-generation 'intelligent' software applications. Wireless network performance in such simulated environments is characterized by the sustainable throughput of data under different traffic conditions. This data will be used to help plan the addition of more access points supporting new modules and more nodes for increased network capacity as the ISS grows.

A fundamental goal of solar system exploration is to understand the origin of the solar system, the initial stages, conditions, and processes by which the solar system formed, how the formation process was initiated, and the nature of the interstellar seed material from which the solar system was born. Key to understanding solar system formation and subsequent dynamical and chemical evolution is the origin and evolution of the giant planets and their atmospheres. Additionally, the atmospheres of the giant planets serve as laboratories to better understand the atmospheric chemistries, dynamics, processes, and climates on all planets in the solar system including Earth, offer a context and provide a ground truth for exoplanets and exoplanetary systems, and have long been thought to play a critical role in the development of potentially habitable planetary systems. Remote sensing observations are limited when used to study the bulk atmospheric composition of the giant planets of our solar system. A remarkable example of the value of in situ measurements is provided by measurements of Jupiter's noble gas abundances and helium mixing ratio by the Galileo probe. In situ measurements provide direct access to atmospheric regions that are beyond the reach of remote sensing, enabling the dynamical, chemical and aerosol-forming processes at work from the thermosphere to the troposphere below the cloud decks to be studied. Studies for a newly proposed Saturn atmospheric entry probe mission named Hera is being prepared for the upcoming European Space Agency Medium Class (M5) mission announcement of opportunity. A solar powered mission, Hera will take approximately 8 years to reach Saturn and will carry instruments to measure the composition, structure, and dynamics of Saturn's atmosphere. In the context of giant planet science provided by the Galileo, Juno, and Cassini missions to Jupiter and Saturn, the Hera Saturn probe will provide critical measurements of composition, structure, and processes that are not accessible by remote sensing. The results of Hera will help test competing theories of solar system and giant planet origin, chemical, and dynamical evolution.

Web pages are ubiquitous and accessible, but when compared to stand-alone applications they are limited in capability. The Alaska Volcano Observatory (AVO) Remote Sensing Group has implemented web pages and supporting server software that provide relatively advanced features to any user able to meet basic requirements. Anyone in the world with access to a modern web browser (such as Mozilla Firefox 1.5 or Internet Explorer 6) and reasonable internet connection can fully use the tools, with no software installation or configuration. This allows faculty, staff and students at AVO to perform many aspects of volcano monitoring from home or the road as easily as from the office. Additionally, AVO collaborators such as the National Weather Service and the Anchorage Volcanic Ash Advisory Center are able to use these web tools to quickly assess volcanic events. Capabilities of this web software include (1) ability to obtain accurate measured remote sensing data values on an semi- quantitative compressed image of a large area, (2) to view any data from a wide time range of data swaths, (3) to view many different satellite remote sensing spectral bands and combinations, to adjust color range thresholds, (4) and to export to KML files which are viewable virtual globes such as Google Earth. The technologies behind this implementation are primarily Javascript, PHP, and MySQL which are free to use and well documented, in addition to Terascan, a commercial software package used to extract data from level-0 data files. These technologies will be presented in conjunction with the techniques used to combine them into the final product used by AVO and its collaborators for operational volcanic monitoring.

The objective of this article is to provide an overview of the clinical experience of our telemedicine network (TOCOMAT) for fetal well-being assessment through computerized Cardiotocography (cCTG), analyzing cultural, socioeconomic, and environmental conditions of pregnant women and its economic sustainability over time. We used the central data store, including all cCTG records collected in Campania region (Italy) during 17 years of activity. The Operations Center acquires the traces recorded in the Remote Units and simultaneously performs a complex fetal heart rate analysis. An Internet or phone conference calling is available to discuss the information transmitted. Finally, the report is send back to the Remote Units. The number of cCTG traces performed was constantly increasing, despite the progressive reduction in the number of peripheral units involved. Pregnant women in Remote Unit group were younger and overweight and showed a higher incidence of diabetes and fetal defects than Operations Center ones. Moreover, a high rate of African migrant women and low socioeconomic and cultural standards were found in Remote Unit group. The cost analysis showed an economic advantage both in the reduction of inappropriate admissions and in the improvement of admission indicators (hospital stay days) for pregnant women. The global economic recession has had a significant impact on the Italian regional healthcare system and socioeconomic deprivation. Telemedicine could avoid unnecessary referral to Level III centers (Hospital) in Campania region, where the average population density is very high, allowing equal access to ultra-specialist assessment irrespective of the geographical location of the pregnant woman with medium to high risk, as well as rationalizing the costs for maternal and fetal care.

Assessing the influence of sustainable trail design and maintenance on soil loss

Marion, Jeff; Wimpey, Jeremy

2017-01-01

Natural-surfaced trail systems are an important infrastructure component providing a means for accessing remote protected natural area destinations. The condition and usability of trails is a critical concern of land managers charged with providing recreational access while preserving natural conditions, and to visitors seeking high quality recreational opportunities and experiences. While an adequate number of trail management publications provide prescriptive guidance for designing, constructing, and maintaining natural-surfaced trails, surprisingly little research has been directed at providing a scientific basis for this guidance. Results from a review of the literature and three scientific studies are presented to model and clarify the influence of factors that substantially influence trail soil loss and that can be manipulated by trail professionals to sustain high traffic while minimizing soil loss over time. Key factors include trail grade, slope alignment angle, tread drainage features, and the amount of rock in tread substrates. A new Trail Sustainability Rating is developed and offered as a tool for evaluating or improving the sustainability of existing or new trails.
