A
1. -privacy/security of patient info (patient 16 digit ID stored on the chip may be viewed by outsiders or hackers enabling them to access to patients info stored on database if they hacked the password)
-reliability of the transfer data (scanner or chip might not be working properly resulting in producing wrong patient ID number when the patient is scanned)
-reliability of the database where data is stored (the error might occur resulting in loss of data when needed during emergency situations)
stakeholder:
-patients whose medical history is stored
-medical staff: doctors and nurses who uses this IT system for the care of the patients

B
1. -patient is implanted chip into arm
-special scanner is passed within 6 inches of the implant
-device emits a radio signal that beams the 16 digit ID into scanner
-number is linked to medical record
-medical staff that have granted access can view medical record

-patient is implanted with the chip into their arm
-the chip is encode with unique ID
-data stored withion RFID tag microchip waits to be read
-the tag antenna receive electromagnetic energy from an RFID reader antenna
-using power from its internal battery/power harvested from the readers, electromagnetic field, the tag sends radio waves back to the reader
-the reader picks up the tag radio wave and inteprets the the frequencies as meaningful data
-the reader displays 16 digits ID at the scanner
-medical staff log in to patients database with valid credentials
-medical staff are able to view the records

2.
-privacy
if data is interpreted by hackers during transfer of ID from the implantable chip to the reader
if passwords are not used on the medical records unauthorised access is possible
-reliability
if there is a malfunction of the reader/chip when reading the data
if there is an error during transmission resulting in incorrect data transfer
if medical records consists of bug
-security
if the 16 digit ID is not encrypted allowing hackers to gain the ID and clone it
-health
the chip that is encased in glass is broken or migrate resulting in some health problems (lethal cancer)

C

Electronics: The Truth about 'E-waste' and Recycling Your Gadgets

# data[].attributes.body
Electronics such as our smartphone, tablets and laptops have become part of our lives whether it is at work or at home. These amazing gadgets are filled with wonderful features which creates life more colourful than it was yesterday. Despite in taking care of these gadgets with care, they are bound to become outdated for the next couple of years. Or maybe you are the kind of person who chases after the new models and dumped the old ones that had dedicated their lives for you.

Some people either just keep these old gadgets in a drawer or probably just toss it into the bin. Though, they are those who are thoughtful enough to donate these old but useful gadgets to the needy. (or just passing the responsibility of disposing it to someone else). These electronics are very complex thus disposing them correctly is also a huge challenge faced by the authority.

The electronic waste-E-waste- has started to become a big attention when a research was done in China. China is known be the hub of all of these disposal, the waste typically consist of mobile phones, television etc. From the research, the locals in the specific area closed to the e-waste dump site are exposed to harmful toxic substances caused by dismantlement activities of these waste. What worries the researches are that these substances may lead to DNA damage which could induce oncogensis due to high rate of IL-8 and ROS levels (indicators of inflammatory responses and oxidative stress)

What exactly are in these gadgets that can harm us users if 'open' dismantlement occur? Materials such as Cadmium, Lead and Mercury can put our health in great danger if we are exposed to them for a long time.

As a conclusion the public should be aware of the problem and start taking action. A quick reminder is given to those who would wish to recycle their computers, data from the computer will be destroyed when recycling occurs. But deleting yourself would be a greater choice because if your important data falls on the wrong hands, you will put your safety at risk.
