ICT Research

My research for this semester was about: Online services and health and safety.

I used prezi to make it, here is the link and the screen shots of what I have done:

Case Study: Effect of ICT on Medical and Hospitals Systems

 Case Study: Effect of ICT on

 Medical and Hospitals Systems

ICT is improving day by day, and as it improves it affects our lives more and more. ICT have affected many jobs including: teaching, businesses, medicine, etc… Computer systems and ICT are used in several quite different ways within doctor's surgeries and hospitals...

Monitoring of Patients:)

When a patient is in hospital, they often require close monitoring. It is not possible for a doctor or nurse to monitor patients continuously, 24 hours a day, so computerised monitors are used instead.

Sensors are attached to the patient. Sensors are used to monitor:

·       Pulse rate (heart beats per minute)

·       Temperature

·       Breathing rate (breathes per minute)

·       Blood oxygen levels

·       Blood pressure

The sensors feed information back to a computer which processes the data:

·       Data is checked for any problems (e.g. pulse rate too low/high)

·       Data is logged so that it can be checked later

Several outputs from the computer system let hospital staff the patient's condition:

·       A large display / monitor shows graphs of pulse, breathing, etc.

·       A loud buzzer / alarm can be sounded if there is a problem to attract the attention of a nurse/doctor

·       A small printer can produce a hard-copy of the data

The data from several patients can be fed back to a central nursing station so that the nursing staff can see exactly what is happening in the ward.

Diagnosis of Illness:)

Body Scanners:)

CT scanners and MRI scanners allow doctors to investigate what is happening inside a patient's body without intrusive surgery. The complex signals that come back from these huge machines are picked up by sensors and fed into a computer. The computer processes the data, then outputs full-colour images, sometimes in 3D, for the doctor, giving views of the patient's body.

Expert Systems:)

Expert systems allow medical staff with limited medical knowledge (e.g. nurses) to get advice from a computer 'expert'.  They essentially work by:

1.        Medical staff inputs patient's symptoms (or answers questions about them).

2.       The expert system's search engine searches the knowledge base (a collection of medical knowledge) to find possible diagnoses.

3.       The system outputs a list of possible diagnoses, and treatments.

Managing Patient Records:)

Doctors and hospitals have to deal with thousands of patients every week. It is essential that the medical details of every patient are recorded accurately so that the correct diagnosis can be made, and the correct treatment can be given.

For this reason, hospitals make use of computerised databases to store patient records. Computerised databases mean that:

·       Patient data can be easily shared between doctors, pharmacies and other hospitals

·       It is easy to search for and retrieve patient records

·       Doctors can instruct a pharmacy to issue medication for a patient (no paper note needs to be written)

 In the case of hospitals, the patient data that would be typically stored would be:

·       Patient ID (number or text) - this would be the key field

·       Name (text)

·       Date-of-birth (date)

·       Gender (Boolean)

·       Blood group (text)

·       Allergies (text)

·       Medical history (text)

·       Doctor currently treating (text)

·       Current symptoms (text)

·       Current diagnosis (text)

·       Current treatment (text)

·       Current medication (text)

·       X-rays or body scans (links to image/video files)

The digital divide or information literacy

              The digital divide or information literacy

Q1) define digital divide.

A1) The idea of the "digital divide" refers to the growing gap between the underprivileged members of society, especially the poor, rural, elderly, and handicapped portion of the population who do not have access to computers or the internet; and the wealthy, middle-class, and young people living in urban and suburban areas who have access.

Q2) Identify the main effects of digital divide on society.

A2) 1- A person who doesn't have all the newest gadgets becomes an outcast in society.

2- Older generations face great difficulties connecting with the younger ones, an age group gap is created.

3- These poorer nations are unable to afford the initial start up cost to be able to invest into technology to allow their nation to be able to have and maintain internet access. This puts these countries at a competitive and economic disadvantage

4-  By a country not having internet access, it means that schools are unable to teach IT skills and take advantage of the vast amount of information available on the web.

Q3) Explain a real case study on bridging the digital divide gap.

A3) many organisations have sent many of their employee to courses either in the same country or in a foreign countries to learn more about modern technology. many organisations have sent their employee to workshops to improve their ICT skills. other organisations have sent them to courses paid by the organisation itself for the employee to learn ICT for those who have a little knowledge about it. also sometimes the organisation would allow employee who have a vast knowledge about ICT to help or teach other employee who who aren't good at ICT.
