Ergonomics is about the safety and wellbeing of people in the workplace.

Some important factors of ergonomics are:

Chair– the chair is one of the most important things to get right. The ideal chair is easy to adjust, have the backrest slightly reclined (1oo° – 110°) and  have a firm, wide and well padded seat. The seat of the chair should be a little slanted back because it forces you to lean into the backrest which helps you to maintain a good  posture. The chair should be adjusted to a comfortable position but allows you to have your feet on the ground. For smaller users a footrest is recommended.

Desk– The desk should allow the computer to be 60 – 78 cms off the ground. A thin desk ( less than 2.5 cms) is recommened because it allows you to have more leg room. The desk should also be big enough to hold all the equipment required.

Monitor– The monitor should be adjusted so the top of the screen is just below your eye level. You should be using maxium contrast but minimum brightness. The monitor should be positioned directly in front of you.

Keyboard and mouse – A detachable keyboard is a good idea because it allows you to position it to where it is comfortable for you. You shouldn’t pound or overreach  the keys as this sends shockwaves up your arm which can lead to health problems. The mouse should be placed on a level surface within easy reach. The index finger should be on the left button , the middle finger should be on the right button and the rest of the fingers should be on the right.

 Ergonomics is an important topic to learn about because it allows computer users to become aware of the various health problems that can occur. Some health problems that can occur are Occupational Overuse Syndrome (OOS) and Repetitive Strain Injury (RSI) which include discomfort in the muscles and tendons. Factors that can cause  OOS and RSI include a bad setup of computers / furniture, a poor workstation layout and poor planning for VDU ( Visual Display Unit) work.

 For individuals to keep free of health problems care should be taken when choosing  furniture and hardware. The layout of the workstation is also important to help reduce the amount of noise (e.g. don’t position the workstation near printers and photocopiers), glare and reflections (e.g. away from windows). To avoid eye strain the computer user should blink often to prevent their eyes drying out , stare off into space occasionally, adjust screen brightness, dust screen off regularly and use a glare screen in case of excess glare. Frequent work breaks are required to help prevent eyestrain and other health problems. A ten minute break every hour is a recommended amount break time. Micropauses are a short break of about five – ten seconds every three minutes. Micropauses help to restore blood flow and help you to be more productive with your work.

 There are several exercises that can help to relax your muscles and tendons. Some of the exercises are:

1. Let your shoulders go loose and shake your arms. Shrug your arms straight up and do. 

  2. Rotate your shoulders in circles as big as you can in both directions. Hold your body still and let your arms hang.head to shoulder exercise

3. Hold your shoulders still and your head forward. Bend your head towards one of your shoulders. Return your head to the normal position and repeat on other shoulder. shoulder.                                                                        This is  a diagram of  exercise 3. →

 9 to 3 (one side of the room to another)

 Close your eyes for a few seconds to relax them. Open your eyes. Begin at 12 and circle your eyes around to 3, 6, 9 and then back to 12. Remember that 12 is the ceiling and 6 is the floor.IMGP9206

 The school computer lab could be improved by purchasing wrist rests , anti- glare screens for the computers that require them, adjustable chairs and document holders (to improve posture by not having to lean over the keyboard).

During the school holidays I went to Tunarama with my friends for a birthday party. There weren’t many rides at Tunarama this year as there had been in previous years. My friends and I went on two of the rides- The Magic Carpet and the Energy Storm. We first went on the Magic Carpet which is a ride which has two rows of seats and takes you up high into the sky. You stay on the top for a few seconds and then it spins you down really fast and then back up again to the top. As you spin down it makes your stomach feel really weird. The pressure of the wind as you go down and back up again makes you push up against the seat next to you.

The Energy Storm was  more scary then The Magic Carpet. On the Energy Storm there are three blocks of seats. The Energy Storm starts off by spinning your block around. Without even realising as it gets faster you start to go higher up off of the ground. Once you are up high enough your block is turned upside down and you are spun around faster than before. The Energy Storm does this a few times but at different speeds. It started off spinning slow and then got really fast.

Once the Energy Storm had finished I felt sick along with a few of my friends. We gave the rides a rest for a moment and went for a walk around to see what else was there. Nothing else really interested us so we went shopping along the front street. We went into about every store but I think out of all of  us only one thing was brought. We then had lunch and by the time we had walked back to Tunarama it was time for me and one of my friends to leave.

Number 173

Unjournallying #173.
The Bulwer-Lytton fiction contest is held every year to recognise the author
of the worst possible opening line for a book. (Find more information at, where www stands for “Wretched Writers Welcome.”)
To enter, contestants simply submit the worst sentence they can imagine to begin a book.

The contest is in “honor” of Edward George Bulwer-Lytton, who began a book
in 1830 with this long sentence: “It was a dark and stormy night; the rain fell in torrents-
except at occasional intervals, when it was checked by a violent gust of wind which
swept up the streets (for it is in London that our scene lies), rattling along the housetops,
and fiercely agitating the scanty flame of the lamps that struggled against the darkness.”

Try your hand at writing a really bad sentence for the contest.

To me, the ocean is full of terrible and viscious creatures that are lurking in the deep dark sea, where they are cleverly disguished by the darkness of the water and the seaweed.

I found this task a little hard. I didn’t really know what to write and how to write it.

Tomorrow When The War Began


Posted by Froggy | Posted in Uncategorized | Posted on November 26, 2010

Tomorrow when the war began is probably one of the best movies I have seen in a while. It’s really intense and action packed with bombs going off here and there. It was really loud though but I think that would be because it was at the cinema and there were only six other people there , serious.  The movie was about some teenagers going on a camp before the school holidays ended. Their camping trip is turned upside down when they see a series of army planes flying overhead. They go back early and find the town deserted all except for the showground…. That’s all I’m going to tell you. If you want to find out more watch it. Just in case you didn’t read it before in this post if you go to the cinema and there are less than 6 other people there , sit as far away from the speaker as possible.

Tomorrow When the War Began

Family and Friends :)


Posted by Froggy | Posted in Uncategorized | Posted on November 25, 2010

My friends and family mean everything to me. Without them I wouldn’t be able or wouldn’t want to do many things that I do do. I mean , without my family I wouldn’t be able to play sport or go on camps because my parents usually pay for that. Also without my family I wouldn’t have anyone to go home to after a hard day at school or anyone to really talk to at home if I am having problems with my friends. Eventhough I don’t always act like I love them because they are embarassing or just annoying really I do and wouldn’t know what to do without them.

My friends  are the reason I go to school and play sport. As the years go by you learn that your friends are like tattoos – some are permanent and will stick by you when you need them and some are temporary that are only in your life for a short time.Without my friends I wouldn’t know how I would get through those 6 hours of school. My friends are fun and energetic – what more could you ask for ? Sometimes they get in trouble because a few of them have big mouths but that just brings more fun.
