RFID tags used to monitor hikers’ health

Filed under: Health,Science by Branko Collin @ 8:26 am

Researchers from the Radboud University in Nijmegen used RFID tags during the recent Four Day Marches to experiment with health monitoring. Volunteers were asked to swallow an RFID pill which sent the hiker’s body temperature to a receiver in their back pack every 10 seconds. The receiver would then relay that information via Bluetooth to a GPS-enabled mobile phone which in turn would forward the data to the operations centre at the university’s teaching hospital.

Using the data, the researchers could track the walkers on Google Maps, and even alert nearby walkers should a volunteer be in trouble. Radboud University was in the news earlier this year when researchers cracked and cloned London’s Oyster travel card and the Dutch public transportation card, which both used NXP’s Mifare RFID chip.

Virtual train compartment for restless elderly

Filed under: Art,Design,Health by Branko Collin @ 10:28 am

Earlier this year the inmates residents of a nursing home for the elderly called De Bieslandhof in Delft got a virtual train compartment to lounge in. The compartment which consists of a number of seats and screens placed in portrait position was commissioned by the home itself in cooperation with SKOR (Foundation for Art and Public Space). The screens show a Dutch landscape of tree-lined meadows gently rolling by.

Says SKOR:

Groups of residents can have a cup of tea or coffee in De coupé [the name of the objet d’art, translates as The compartment—Branko] as well as receive a hot meal. Moreover, the work seems to have an added therapeutic value since the more restless residents who used to constantly stand in front of closed doors because they wanted to escape from the nursing home, are now calmly enjoying a few hours in De coupé instead.

And the artists, Lino Hellings and Yvonne Dröge Wendel, document the process (Dutch) in their online diary:

We now have a good idea of what the video should look like. 80 % sky with cumulus clouds and 20 % underexposed landscape, preferably rows of trees. The view should be filmed in landscape mode, then cut in two, and twice recorded vertically. The same image is shown mirrored on the other side.

We discover an old steam train between Hoorn and Medemblik. The windows are perfect, as is the speed. We use old socks filled with coffee beans as a camera stand.

RSI not related to excessive computer use

Filed under: Health,Technology by Branko Collin @ 7:34 am

Geeking out does not necessarily lead to repetitive strain injury. A study by Stefan IJmker at the Vrije Universiteit in Amsterdam shows that it doesn’t matter how long or often you sit behind a PC, these factors do not lead to RSI. Instead, a combination of factors that are all members of bad job syndrome, such as little appreciation and little variation, are the great sick-makers. A history of RSI also significantly increases the chances of the injury returning.

IJmker tracked 2,000 office workers for two years using forms and software that registered how much time subjects spent on tasks.

Earlier studies did show a connection between the amount of computer use and RSI, but almost all of these studies relied on having subjects report on their own usage patterns. IJmker’s research also shows that people who got RSI tended to overestimate how much they used the computer. The researcher will defend his thesis today.

Badly chosen picture with health article

Filed under: Food & Drink,General,Health by Orangemaster @ 9:51 am

I don’t care about the story, it’s the picture that basically cancels out the story for me. The story is about “experiments to increase health with young people,” which sounds fine, but the picture shows a teenager eating ontbijtkoek, which for the foreign crowd is gingerbread for breakfast. And it’s chocked full of sugar and fat. The background shows a vending machine with Balistos, a muesli (granola) based candy bar, with chocolate and tons of sugar. The captions read “Eating healthy in the cantina of the Werkplaats Kindergemeenschap.”

Did the photographer just do their job or is the author of this article stupid, unaware, fat or something else? With this kind of well-intended advice, no wonder Dutch kids are getting fatter. The road to obesity is paved with junk food.

Food that tastes like less

Filed under: Food & Drink,Health,Science by Orangemaster @ 9:23 am

Scientists in Wageningen are developing a new generation of foods that can help prevent obesity by getting people to eat less. The Top Institute Food and Nutrition is also developing food ingredients which can stop obese people from developing diabetes. Such nutrients could eventually be used in any kind of food. The Dutch public health agency concluded in a research report last year that 25% of deaths and serious illness caused by overweight and obesity would be avoided if adults shed 3 kg.

Eating right and exercising is pretty straight forward, but accommodating the obese seems more lucrative. As the article states, “such innovative products have higher margins than those of selling a tomato or a bottle of milk.”
