Basic rural hygiene (Nakaseke)(UNESCO)

The focus of this simulation is on disease prevention, good sanitation, personal hygiene and other domestic practices that are based on water.

The simulation looks at issues that lead to water-borne diseases (typhoid, dysentery, and cholera), water based diseases (malaria, bilharzia) and water washed disease (caused by poor hygiene and not bathing regularly).

AIDS "The impact of poverty vs. affluence" (IICBA)

This i3dlo is a great example of the reusability of i3dlo’s - this one was originally developed to show the main principles of a first-class lever, but has however been used more often to demonstrate how “poverty” can negatively impact on the life expectancy of those who find themselves HIV positive.

Four parameters are used to show this – quality of diet, exercise, treatment and hygiene can be adjusted via sliders and which in turn impact on how far the catapult will throw its load. In a state of affluence, the load is thrown a long way (live a long time) whilst in a state of poverty, the converse often happens as conditions combine to shorten a person’s lifespan. The message is of course, take care of these conditions and one can live longer with the HI Virus.

The relationship between CD4 cell count and HIV/AIDS (IICBA)

Officially, a person with the AIDS syndrome is one where the CD4 cell (white blood cell) count has fallen to 200 from a typical norm of 1200. At such low levels, the human body is unable to fight ANY incoming infection. This i3dlo shows how exercise, treatment, diet and hygiene can impact on the rate that the CD4 cell count declines.

Africa Map - HIV infection rates (IICBA)

This i3dlo shows the relative HI Virus infection rates by African country. It can also be customised to show any national statistics as two sets per country and the 3d map can be rotated or zoomed into.

World and Africa Map - HIV infaction rates (IICBA)

Visualization is a powerful way to look at data in new ways. In this example, we look at global HIV infection rates in a way that has never been seen before.

We know how the world’s continents look like on a map, but see how our view can change when the continents are re-scaled according to GDP or HIV infection rates… (Based on 2004 UNDP data)

Ultraviolet germicidal irradiation (UVGI) system (ESKOM)

This simulation shows a UVGI system that can be used to kill germs and thus combat the spread of Tuberculosis and other airborne diseases. It is typically used in clinics and other areas where people congregate. It requires very little maintenance, is fairly cheap to run and the lamps typically last for about 1 to 3 years. The germs that are in the air in the room are killed when the air circulates through the irradiated region.

Tele-medicine (ESKOM)

This simulation shows how “Telemedicine” can be used to allow health care professionals to "connect" medical devices in the evaluation, diagnosis and treatment of patients in remote locations. These devices use telecommunications technology, network computing and video-conferencing systems. Telemedicine uses two methods to transmit images, data and sound.
