The development of telemedicine programs in Sub-Saharan Africa: Progress and associated challenges

Monitoring the progress of telemedicine use in Sub-Saharan Africa (SSA) countries has received a considerable attention from many health organizations and governmental agencies. This study reviewed the current progress and challenges in relation to the development of telemedicine programs in SSA. The results from reviewing 66 empirical studies revealed an unbalanced progress across SSA countries. Further, technological, organisational, legal and regulatory, individual, financial, and cultural aspects were identified as the major barriers to the success of telemedicine development in SSA. This study reported the current trends in telemedicine application, as well as highlighting critical barriers for consideration by healthcare decision makers. The outcomes from this study offer a number of recommendations to support wider implementation and sustainable usage of telemedicine in SSA

Update propagation algorithms for supporting disconnected write in mobile wireless systems with data broadcasting capability

We develop and analyze algorithms for propagating updates by mobile hosts in wireless client-server environments that support disconnected write operations, with the goal of minimizing the tuning time for update propagation to the server. These algorithms allow a mobile host to update cached data objects while disconnected and propagate the updates to the server upon reconnection for conflict resolutions. We investigate two algorithms applicable to mobile systems in which invalidation reports/data can be broadcast to mobile hosts periodically. We show that there exists an optimal broadcasting period under which the tuning time is minimized for update propagations. We perform a comparative analysis between these two update propagation algorithms that rely on broadcasting data and an algorithm that does not, and identify conditions under which an algorithm should be applied to reduce the total tuning time for update propagation by the mobile user to save the valuable battery power and avoid high communication cost. For real-time applications, we address the tradeoff between tuning time and access time with the goal to select the best update propagation algorithm that can minimize the tuning time while satisfying the imposed real-time deadline constraint. The analysis result is applicable to file/data objects that mobile users may need to modify while on the move

Turing-Test Evaluation of a Mobile Haptic Virtual Reality Kissing Machine

Various communication systems have been developed to integrate the haptic channel in digital communication. Future directions of such haptic technologies are moving towards realistic virtual reality applications and human-robot social interaction. With the digitisation of touch, robots equipped with touch sensors and actuators can communicate with humans on a more emotional and intimate level, such as sharing a hug or kiss just like humans do. This paper presents the design guideline, implementation and evaluations of a novel haptic kissing machine for smart phones - the Kissenger machine. The key novelties and contributions of the paper are: (i) A novel haptic kissing device for mobile phones, which uses dynamic perpendicular force stimulation to transmit realistic sensations of kissing in order to enhance intimacy and emotional connection of digital communication; (ii) Extensive evaluations of the Kissenger machine, including a lab experiment that compares mediated kissing with Kissenger to real kissing, a unique haptic Turing test that involves the first academic study of humanmachine kiss, and a field study of the effects of Kissenger on long distance relationships

A framework for evaluating telemedicine-based healthcare inequality reduction in Ethiopia : a grounded theory approach

Text in EnglishTelehealth makes healthcare services accessible by underserved and resource-constrained rural communities of developing countries such as Ethiopia. However, the limitation of frameworks on telemedicine-based healthcare inequality reduction is a challenge for developing countries. In Ethiopia there are four telemedicine projects; however, there is no evidence that any of these projects have been evaluated by considering contextual issues. This academic research explored telehealth practices in Ethiopia with the aim of developing a comprehensive telehealth evaluation framework for developing countries. Such a conceptual framework could be used to inform health institutes and governmental policy makers and in so doing create a vehicle for the implementation of improved health practices in Ethiopia. A grounded theory approach is used to qualitatively explore the usefulness of telemedicine practices in Ethiopia, in mitigating healthcare inequality. Grounded theory makes use of emerging insights in order to contribute to new knowledge. From the inductive analysis of the study, themes such as barrier removal, service quality, synergetic effect, localization, technical setup, resource utilization and managerial readiness emerged to formulate a framework for evaluating telemedicine-based healthcare inequality reduction in the context of developing countries like Ethiopia. This study contributes to the understanding of the question of how telemedicine practices can be evaluated, to support the healthcare service and reduce the healthcare inequalities in resource constrained communities in Ethiopia. Moreover, the framework could be used during evaluation of telemedicine-based healthcare inequality reduction in the context of developing countries like Ethiopia.School of ComputingPh.D. (Information Systems

Strategic vision toward the next-generation telecom industry

Thesis (S.M.)--Massachusetts Institute of Technology, Sloan School of Management, 2010.Cataloged from PDF version of thesis.Includes bibliographical references (p. 111).Telecommunication industry is experiencing volatile change in technology and business model. Every telecom company needs strategy that gives direction through rapidly shifting environment. NTT, Japanese telecom giant is not exception. In this thesis, Delta model is utilized to obtain strategy that leads effective management and operation of future NTT. Another objective of this thesis is to understand the effect of different strategic bias and finding way to overcome difficulty of distinction between strategic opinions. Although Delta model is containing theoretical essence from all strategic fields, it has focus on rational planning and positioning view. This results some difficulty to apply Delta model for NTT that recently biased by emergent strategic view through experiences of continuous fight against threat from emerging new technologies and services. To fill this gap, alternative theories of Disruptive Technology, Invisible Asset, Overextension, and Organizational Knowledge Creation are applied in combination with Delta model and examined. Through experimental mixture of Delta model and alternative theories, I obtained NTT's strategic perspective and recommendations for technology development, business globalization, and preparation against future threat.by Kenji Yoshioka.S.M

Firewall strategies using network processors

The emergence of network processors provides a broad range of new applications, particularly in the field of network security. Firewalls have become one of the basic building blocks of implementing a network\u27s security policy; however, the security of a firewall can potentially lead to a bottleneck in the network. Therefore, improving the performance of the firewall means also improving the performance of the protected network. With the ability to direcdy monitor and modify packet information at wire speeds, the network processor provides a new avenue for the pursuit of faster, more efficient firewall products. This paper describes the implementation of two simulated network processor based firewalls. The first architecture, a basic packet filtering firewall, utilizes tree-based structures for manipulating IP and transport level firewall rules while also utilizing parallelism available in the network processor during firewall rule look-ups. In the second architecture, a parallel firewall is created using a network processor based, load-balancing switch along with two network processor based firewall machines, both utilizing the basic packet filter operations of the first architecture. When added to existing routing software, these implementations demonstrate the feasibility of creating dynamic packet-filtering routers using network processor technology

Deployment related mental health care seeking behaviors in the U.S. military and the use of telehealth to mitigate their impacts on access to care

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Aeronautics and Astronautics; and, (S.M. in Technology and Policy)-- Massachusetts Institute of Technology, Engineering Systems Division, Technology and Policy Program, 2012.Cataloged from PDF version of thesis.Includes bibliographical references (p. 189-193).Interviewees report that groups of service members returning from Iraq and Afghanistan often require substantial amounts of mental health care, causing surges in demand at military hospitals. These hospitals have difficulty keeping up with demand during the busiest periods. The exact patterns of demand during surges are difficult to measure because the military records utilization, but not actual need for services. This thesis analyzes the care seeking behaviors of service members and their families across the deployment cycle using historical data. This analysis shows that service members and their families seek more care after each deployment. More importantly, it shows that service members seek care at higher rates in predictable intervals following their deployments. New patient arrival rates are projected for several installations by multiplying actual installation populations by newly calculated care seeking rates. These projections show deployment related care seeking behaviors generate surges in demand and thereby validate qualitative findings from field work. A simulation of the military's system of care uses these demand projections to specify patient arrival patterns. Comparison of several simulated scenarios shows that surges make it very difficult for individual military hospitals to offer access to care using only their own mental health care providers. Allowing hospitals to share their providers with one another offers little improvement. As hypothesized, using a group of dedicated telehealth providers to support the most overburdened installations can offer a substantial improvement in access to care. This insight leads to four policy recommendations. First, a service wide or joint scheduling system should be created. Second, telehealth can best support overburdened hospitals when some providers are dedicated solely to surge support. Third, the services should take responsibility for meeting access to care goals instead of delegating the burden to installations. Lastly, hiring actions should be tied directly to an accurate measurement of excess demand.by John Hess.S.M.in Technology and PolicyS.M
