Task 7. Read the article from “Health
and Science Digest”.
HEALTHCARE 2.0
New advances in Medical
Technology.
Health
technology is a rapidly growing field. New advances aim to improve care and
reduce costs.
The EHR (Electronic
Health Record) is one technology already in place. EHRs let doctors access
patient data easily and efficiently. They also enable CDSS (Clinical Decision
Support System) functions. These alert doctors to harmful drug interactions.
EHRs can also store data from PACS (Oicture Archiving and Communications
System). Interoperability is a key aspect of EHRs. It lets physicians in
different clinics easily share records.
Other technology
has also become popular. Many doctors use CPOE (Computerized Provider Order
Entry) systems. These reduce handwriting and communication errors. Bar coding
is another common practice. Here, doctors use optic scanners to match patients
to their medicines. They often use ADMs (Automatic Dispensing Machines). These
dispense drug dosages, which can reduce dosage errors. Many hospitals use EMM
(Elctronic Materials Management) systems. These keep track of drugs and other medical
supplies.
Some technology is
still in development. With the lab-on-a-chip, doctors will not have to send
cultures to labs for analysis. Micro robotic tweezers will let doctors operate
in very small areas. Implanted microchips will measure and release drug dosage
precisely.
Task 8. Mark the following statements as
true (T) or false (F).
1.CPOE
system help to reduce mistakes related to handwriting.___
2.Doctors
use optic scanners to measure and release precise doses.___
3.The
lab-on-a-chip has saved money and labs. ___
Task 9. Match the words with the
definitions.
1___implanted
michrochip 5___interoperability
2___PACS 6___bar coding
3___EHR 7___micro
robotic tweezers
4___lab-on-a-chip
a.
a computerized version of a patients ‘health record
b.
a device that holds cells and fluid that a doctor can analyze easily
c.
a system in which doctors scan medicines and match them to patients
d.
very tiny tools that let a doctor operate in very small areas
e.
a tiny device in a peson’s body that releases medicine
f.
the ability to send electronic health data between systems
g.
a system that stores medical images from different sources
Task 10. Circle the correct response (a
or b) to the questions.
1. Have you used CPOE before?
a. Yes, I’ve used it to share
records with doctors.
b. Yes, I’ve used it to
fill out a prescription.
2.Why CDSS helpful?
a. It helps doctors diagnose and
treat patients.
b. It allows doctors to
access patient data easily.
3.What is an optic scanner for?
a.You can use it to read and
record information on medicine labels.
b.You can use it to
measure out specific amounts of a drug.
4.Are you familiar with ADMs?
a.Yes, I’ve used them to operate
in very small areas.
b.Yes, I’ve used them to measure
out medications.
5.Does
the hospital use EMM?
a.Yes, we use it to analyze cells
and fluid easily.
b.Yes, we use it to keep
track of medicines and supplies.
Task 11. Choose the correct word.
There are three different types
of 1...........(systems/peripherals):
input devices, which interact with or 2........... (send/output) data
from the user to the computer (mice, keyboards, etc.), output devices,
which provide 3............(send
/output) to the user from the computer (monitors, printers, etc.), and input/output
devices that perform both functions. Touchscreens are an example that
combines different devices into a single 4.............
(software / hardware) component that can be used both as an input and output
device.
A peripheral device is generally
defined as any 5 ............
(auxiliary/ main) device such as a
computer mouse or keyboard that connects to and works with the computer in some
way. Other examples of peripherals are image scanners, tape drives,
microphones, loudspeakers, webcams, and digital cameras. Many modern devices,
such as digital watches, smartphones and tablet computers, have 6.................... (protocols
/interfaces) that allow them to be used as a peripheral by desktop computers,
although they are not host-dependent in the same way as other peripheral
devices.
Task 12. Read the text, translate and
make the questions to the sentences.
(10-15)
Embedded systems control many
devices in common use today and ninety-eight percent of all microprocessors are
manufactured as components of embedded systems.
-
Examples of properties of
typically embedded computers when compared with general-purpose counterparts
are low power consumption, small size, rugged operating ranges, and low
per-unit cost.
-
Modern embedded systems are often
based on microcontrollers (i.e. CPU's with integrated memory or peripheral
interfaces), but ordinary microprocessors (using external chips for memory and
peripheral interface circuits) are also common, especially in more-complex
systems.
-
In either case, the processor(s) used
may be types ranging from general purpose to those specialised in certain class
of computations, or even custom designed for the application at hand.
-
A common standard class of
dedicated processors is the digital signal processor (DSP).
-
Since the embedded system is
dedicated to specific tasks, design engineers can optimize it to reduce the
size and cost of the product and increase the reliability and performance.
-
Some embedded systems are
mass-produced, benefiting from economies of scale.
-
Embedded systems range from
portable devices such as digital watches and MP3 players, to large stationary
installations like traffic lights, factory controllers, and largely complex
systems like hybrid vehicles, MRI, and avionics.

The dangers of development
In today's world there is a
constant battle between 1…………development and countryside 2…….. . In many places where areas of 3…………wilderness have been designated
as 4……..zones, governments suddenly announce plans that allow the
developers to move in. The subsequent impact of such projects is usually
devastating for indigenous types of 5………..such as flowers and insects
and many 6………..habitats are permanently destroyed. While the need for
jobs and homes for increasing populations has to be accepted, the developers
need to understand the 7………..their activities pose to the8………….
of many 9………..of fauna and10………….. .
Task 2.
Complete the text below using the correct
form of the words in brackets.
Growing for gold and for a clean
land
A
New Zealand geologist has developed a way of using biotechnology to help the 1…………. (environment) recovery of
2…………(pollute)areas by
harvesting gold from plants. He claims this process can be used to extract
gold, mercury and other minerals from 3…………..(contaminate)
gold mines. He has conducted successful field trials in the Amazon, where local
miners use 4………….(toxin) mercury to extract gold and then simply
leave the sites and move on. The process uses chemicals to break down gold to a
water-soluble form. Once the metals are mixed with water, crop plants such as
com and canola can absorb them along with other 5…………(nutrient) they need for growth. It is estimated that
one kilogram of gold can 6……………(recover)
per hectare in this way. The New Zealand team also trained locals in farming 7…………..(technique), so once the
land is clean, these people can reclaim it for 8……………(sustain) agriculture.
