  • Very low Physician-Patient proportion
  • Healthcare Spending  in 2002 < $40 per person/year
  • Healthcare not becoming more accessible today
  • How to get the technology to people?
    • unreliable supply chains & infrastructure
    •  info not portable
    • compliance
    • false alarm ~ 90%
    • human errors ~40% not atypical
  • mHealth solution
    • allow healthcare & non-healthcare expert to look at the info
    • low cost sensors
  • Use of non-expert opinion to assist in the diagnosis
    • For example,
      • Specific characteristics of ECG data can be determined based on crowd-sourced opinion
    • Well-designed algorithm is critical in filtering out noisy opinions

  • Community Health Workers (CHW) are part of the sustainable solutions
  • Low cost devices are provided to CHW for diabetes detectiion
  • Goal of the project is to find the more effective approach for Knowledge Transfer and Exchange (KTE)
  • General challenges
    • Language barrier
    • Information overload
    • Mistrust
  • Oral communication based in developing world

Technical challenges
1) infrastructure & resource limitations

  • not constant power source all the time
  • no Wifi

2) security

  • not open to have record put on the computer

3) lack of expertise
4) start up cost

  • all monthly wages on a smart phone not feasible

5) equipment reliability and theft

  •  implemented project on the ground in Kenya
  • team of 4 students project: KTE in low resource settings

1) oral script to train locals

– mimics time spent between CHW with a household ~5 min hypertension risk factors basic

– provided paper visuals

2) ask followed up questions to patients after an hour

– Most of them cannot remember about numerical info but other health info

  • Try to see the most effective way to train them
    – need a trust relationship so train the local translator – mimics the CHW not the actual

Here is Nate Johnson, IEEE GHTC Technical Chair, speaking about this year’s variety of technical tracks (1:39).

The first portion of the presentation establish models to evaluate parameters effectiveness to the energy system. It’s a useful tool to do trade studies to determine the priorities of system design optimization. Similar approach could be tailored to different systems or parameters. This approach provides a means to take the system holistically instead of individual components.

The HOMER presentation presented similar approach for different power system architecture in rural area.

AKM Azad presented solar home system component qualification testing procedure. This is the first presentation that works with qualifying actual of the shield product. To provide a comparison, figure of metric is also established.

Nathan presented a study for the new cookstove adoption to the rural area. The figure of merit not only takes the cookfuel efficiency, which includes time to prepare biomass, but also the adaption rate for the cookstove. It shows that a great product may have great performance but lacks of the adaption greatly reduces the value of the product. Also, there is no solution fits all because the “customer” need simply varies from cooking 5lbs to 100lbs food. Differentiation for different needs are needed.

Yaser, the last presenter, adds an new element to the figure of merit on the global level- Peace, to address the conflict of energy resources. It’s an new thought to integrate the energy solution to a larger global scale.

Low cost, low power 12VDC Surgical Suction Device for use in Developing Countries

By Pritpal Singh

The project started because the author was moved by a presentation of a woman from Nigeria in the conference a few years ago, who brought the solar panel box to the conference. The existing technology of surgical suction cost $250-3500 per year. The goal of the project was to develop a low-cost suction device for lower than $50 that can run off 12V power supply. With this project, students in University of Villanova were awarded a prize as well.

Optical Measure of Enamel Health: Ability to Triage High Risk Children without Dental Practitioners

By Liang Zhang

Tooth decay among children is widespread globally. The current primary diagnostic techniques are more than century old. The objective of the project was to develop a simple and robust method to discriminate healthy and diseased enamel. The proposed setup uses spectrometer, and in this project, the technique quality was examined.  For devices to be made in the future, the team is considering to invent a low-cost bench top or handheld device as well as a device to classify between healthy and unhealthy tooth.

‘Gest-BOT’ A highly convenient locomotive solution for the elderly and physical challenged

By Ramesh Nair

The developed product is a wheelchair with the function of gesture recognition. The results of the responses of gesture recognition under different situations were shown in the presentation. The video of working prototype was also shown during the presentation.

Options for Medical Oxygen Technology Systems in Low-resource Settings

By Beverly Bradley

The proposed system is a solar-charged battery system of oxygen technology for developing countries. More of the work will be done in the future in order to achieve the implementation of the proposal.

PartoPen

By Lakshika Paiva

Obstructed labor is a big cause for maternal death in developing countries, especially in rural areas. In order to help on this cause, the team develop the PartoPen to help WHO officers record the partograph with more detailed information as well as more instructions. The author went to Nairobi in Kenya to test the product, and she got positive feedbacks from the nurses in the clinic. They also conducted student pilot, and currently are running the nurse pilot. The next step of the project is to scale up as well as to explore the data collection potential to influence global health.

Empowering smallholders and local food markets with smart phones and social networks
Justin Henriques henrigjj@jmu.edu

Justin Henriques

Justin presented the “FarmDroid” idea which includes hardware and software
the key is provide localized information for the local community;
– heavy subsidized hardware at the beginninge
– potential social community impact
Q&A : literacy becomes a very critical for the success of the program

IPv4/IPv6 Interoperability for VIOP Applications
Olga Mill omill@ieee.org

Olga Mill

The current VOIP devices are in to way to
IPv4 equipment abandonment is imminent due to a IPV4-IPV6 transition. IPv4 is great for small netowrk for larger systems due to IP exhaustion issue.
– provide VIOP system for small network y donating used equipment reuse.
Assumption: donated hardware available.Asterisk PBX free version for IPV4
2 configurations are proposed to provide VOIP with used equipment with open source code to provide low cost for the needed area.

3 speakers presented measurement metrics for the GIS/remote sensing systems.

Richard Bernnopf, an econoedmist, presented his case study of economic impact evaluation of satellite imagery in Idaho. He analyzd satellite imagery of corn/soy bean fields over time and identify the water quality influenced by the government regulation against the economic impacts. With his model, he estimated the economic value of imagery system is 18.1B +/-8 lbs.

Nancy Serby from NASA continued with the NASA collaboration with global agency to establish hubs and data collectionis. for analysis

Mary Stewart closed the gap between data collection and economic impact results by providing a case study of translating data into the results.
