Korean doctors: Smartphones really ARE doing your head in

Warning from the future as gadget-mad Koreans get early onset dementia


Forget Dr Kawashima’s Brain Training, prolonged exposure to digital devices is actually putting children at risk of early onset dementia, at least according to South Korean doctors.

Cases of memory and attention disorders are apparently increasing in gadget-crazy South Korea, one of the most technologically advanced nations on the planet, with youngsters particularly at risk of intensive exposure as their brains are still developing, according to Joongang Daily.

Too much time spent texting, surfing the web and playing online games can apparently lead to degeneration of the right side of the brain, impairing memory and attention span.

“Overuse of smartphones and game devices hampers the balanced development of the brain,” Byun Gi-won, a doctor at Seoul’s Balance Brain Center, told the paper.

“Heavy users are likely to develop the left side of their brains, leaving the right side untapped or underdeveloped.”

The government’s Health Insurance Review & Assessment Service reported that the number of Koreans suffering cognitive problems in the 20-40 age group had risen from 1,160 in 2008 to 1,585 last year.

With South Korea named the world’s most advanced ICT economy for two straight years by the UN, the worry is that these symptoms will soon start to appear in other countries as digital technology begins to penetrate every aspect of our lives.

ICT ministry stats quoted in the report found almost two-thirds of Korean teens have smartphones today, compared to just 21 per cent in 2011, with the number of 10- to 19-year-olds who use their handsets for over seven hours a day at 18.4 per cent – a 7 per cent jump from last year.

Aside from anecdotal evidence from several doctors interviewed for the piece, there are as yet not many hard stats to back up the claims that prolonged and intensive exposure to digital tech will lead to early onset dementia.

Definitive studies into health issues usually take years before they can generate anything close to compelling evidence, by which time we may all be walking round like lobotomised monkeys, although it’s unlikely.

That said, it’s probably not a bad idea to put the fondleslab down once in a while.

The Chartered Society of Physiotherapy warned last year that poor posture and bad working practices associated with technology use can lead to headaches and back and neck pain. ®

  • DigitalOcean tries to take sting out of price hike with $4 VM
    Cloud biz says it is reacting to customer mix largely shifting from lone devs to SMBs

    DigitalOcean attempted to lessen the sting of higher prices this week by announcing a cut-rate instance aimed at developers and hobbyists.

    The $4-a-month droplet — what the infrastructure-as-a-service outfit calls its virtual machines — pairs a single virtual CPU with 512 MB of memory, 10 GB of SSD storage, and 500 GB a month in network bandwidth.

    The launch comes as DigitalOcean plans a sweeping price hike across much of its product portfolio, effective July 1. On the low-end, most instances will see pricing increase between $1 and $16 a month, but on the high-end, some products will see increases of as much as $120 in the case of DigitalOceans’ top-tier storage-optimized virtual machines.

  • GPL legal battle: Vizio told by judge it will have to answer breach-of-contract claims
    Fine-print crucially deemed contractual agreement as well as copyright license in smartTV source-code case

    The Software Freedom Conservancy (SFC) has won a significant legal victory in its ongoing effort to force Vizio to publish the source code of its SmartCast TV software, which is said to contain GPLv2 and LGPLv2.1 copyleft-licensed components.

    SFC sued Vizio, claiming it was in breach of contract by failing to obey the terms of the GPLv2 and LGPLv2.1 licenses that require source code to be made public when certain conditions are met, and sought declaratory relief on behalf of Vizio TV owners. SFC wanted its breach-of-contract arguments to be heard by the Orange County Superior Court in California, though Vizio kicked the matter up to the district court level in central California where it hoped to avoid the contract issue and defend its corner using just federal copyright law.

    On Friday, Federal District Judge Josephine Staton sided with SFC and granted its motion to send its lawsuit back to superior court. To do so, Judge Staton had to decide whether or not the federal Copyright Act preempted the SFC's breach-of-contract allegations; in the end, she decided it didn't.

  • US brings first-of-its-kind criminal charges of Bitcoin-based sanctions-busting
    Citizen allegedly moved $10m-plus in BTC into banned nation

    US prosecutors have accused an American citizen of illegally funneling more than $10 million in Bitcoin into an economically sanctioned country.

    It's said the resulting criminal charges of sanctions busting through the use of cryptocurrency are the first of their kind to be brought in the US.

    Under the United States' International Emergency Economic Powers Act (IEEA), it is illegal for a citizen or institution within the US to transfer funds, directly or indirectly, to a sanctioned country, such as Iran, Cuba, North Korea, or Russia. If there is evidence the IEEA was willfully violated, a criminal case should follow. If an individual or financial exchange was unwittingly involved in evading sanctions, they may be subject to civil action.

  • Meta hires network chip guru from Intel: What does this mean for future silicon?
    Why be a customer when you can develop your own custom semiconductors

    Analysis Here's something that should raise eyebrows in the datacenter world: Facebook parent company Meta has hired a veteran networking chip engineer from Intel to lead silicon design efforts in the internet giant's infrastructure hardware engineering group.

    Jon Dama started as director of silicon in May for Meta's infrastructure hardware group, a role that has him "responsible for several design teams innovating the datacenter for scale," according to his LinkedIn profile. In a blurb, Dama indicated that a team is already in place at Meta, and he hopes to "scale the next several doublings of data processing" with them.

    Though we couldn't confirm it, we think it's likely that Dama is reporting to Alexis Bjorlin, Meta's vice president of infrastructure hardware who previously worked with Dama when she was general manager of Intel's Connectivity group before serving a two-year stint at Broadcom.

  • Lithium production needs investment to keep pace with battery demand
    Report says $42b will need to be poured into industry over next decade

    Growing demand for lithium for batteries means the sector will need $42 billion of investment to meet the anticipated level of orders by the end of the decade, according to a report.

    Lithium is used in batteries that power smartphones and laptops, but there is also rising use in electric vehicles which is putting additional pressure on supplies.

    The report, Benchmark Mineral Intelligence, predicts that demand will reach 2.4 million tons of lithium carbonate equivalent by 2030, roughly four times the 600,000 tons of lithium forecast to be produced this year.
