CBSE INTRODUCES ON SCREEN MARKING

CBSE INTRODUCES ON SCREEN MARKING

ATTENDING OSM WORSHOP AT DPS RANIPUR

Today attended a workshop on OSM( ON SCREEN MARKING). 

Its time to digitize our world. CBSE is all geared to introduced its changed pattern of evaluation OSM. In the first phase batch of 2013- 2014 class X answer sheets would undergo this changed system of evalaution. Answer sheets would be thoroughly scanned and would be opened as scanned copy on the desktop. Using the software the evaluator through his user Id would be allowed to access the scanned answersheets. This would reduce the discrepency of leaving any attempted question as unchecked

Word of advice for the students ;

1. Attempt paper very neatly.

2. Leave lines between questions

3. Write correct question number.

4. Attempt questions sequentially. Subparts of the questions should be attempted together.

LETS SEE HOW THIS OSM REALLY WORKS. HAPPY OSMing!!!!!!!!

Dengue: Symptoms, causes and treatment

The alarming rise in cases of dengue across cities in the country has become a cause of worry.

What is dengue?
Dengue is a disease caused by a family of viruses that are transmitted by mosquitoes. Dengue cannot be spread directly from person to person, i.e., is not contagious. A person can only become infected by the bite of a mosquito that is infected with the dengue virus. It is important to note that these mosquitoes bite during the daytime as well as nighttime.

Symptoms
Dengue usually begins with chills, headache, pain while moving the eyes, and backache. Persistent high fever is characteristic of dengue. Other symptoms to watch out for are exhaustion, backache, joint pains, nausea, vomiting, low blood pressure and rash.

Treatment
Because dengue is caused by a virus, there is no specific treatment for it; treatment of dengue is typically concerned only with the relief of symptoms. People who show the symptoms mentioned above should immediately consult a physician. It is important to drink plenty of fluids, stay hydrated, and get as much rest as possible.

Dengue hemorrhagic fever (DHF)
DHF is a more severe form of dengue and can be fatal if untreated. It tends to affect children under the age of ten, and causes abdominal pain, hemorrhage (bleeding), and circulatory collapse (shock).

Prevention
There is no vaccine to prevent dengue. Prevention of dengue requires eradication of the mosquitoes that carry this virus. This means high standards of hygiene and sanitation. Avoid areas littered with garbage. All containers of stationary water (like drums or buckets) should be covered or discarded, including flower vases and pets' feeding bowls. If your area is infested with mosquitoes, wear long sleeves, use mosquito repellants and fumigate if necessary.

GLOBAL HANDWASHING DAY 15 October 2012

Dos and don’ts of hand washing

80% of all infectious diseases are transmitted by touch. Hand washing is one of the easiest and best ways to prevent infection. Let’s learn how to do it right.

Infections can come from anywhere. Washing your hands from time to time might not keep you away from all of them, but it can definitely help avoid a few. Hand washing is simple, requires just water and soap or in absence of that, a sanitizer.

Why you should wash your hands

People interact with each other, shake hands, go to various places, use various objects and even use common washrooms. It is important to remain germ-free after doing all this. Touching your nose, mouth or eyes with unclean hands can also infect you. Frequent hand washing does not make you germ-free but reduces the transfer of bacteria, viruses and other microbes to a certain limit.

When you should wash your hands

Wash your hands before:
·         Cooking or eating food
·         Wearing or taking off contact lenses
·         Cleaning wounds and giving medicine
·         Treating a sick person
·         Playing with a new born baby
Wash your hands after:
·         Having food
·         Coming home from anywhere
·         Using pesticides or other agents like mosquito or cockroach killers
·         Using the toilet
·         Touching and playing with animals
·         Cleaning wounds or treating a sick person
·         Blowing your nose, sneezing or coughing into your hand
·         Using chemicals in the garden, throwing garbage or any other such household chores that includes some dirty work and requires you to use your hands

How to wash your hands

You wash your hands everyday and might think it is a silly to read a “how-to” on it but it is always better to refresh your ideas and remind yourself on how to do things right.
Generally, handwash/soap and water are used to wash hands. The simple steps are as follows:
·         Wet your hands
·         Apply soap or hand wash
·         Form lather
·         Rub both the hands. Try to clean in between fingers, under the nails and the back of your hands along with wrists. Rub for some 20 seconds
·         Pat dry with a clean or disposable towel or use air dryer.

When to use a sanitizer

Alcohol based sanitizer can be used when water and soap are not available. It is important that your sanitizer contain at least 60% alcohol.

How to use a sanitizer

·         Take a small quantity of sanitizer in your hands and rub it to wet your hands completely.
·         Rub it till your hands are dry.

Kids and hand washing

Good habits must be cultivated from childhood. Kids must be encouraged to wash hands regularly. The best way to teach them is by being a good example. Tell them to sing a line of their favourite song as they wash their hands to stop them from rushing the process
It is okay for the kids to use sanitizers. They are not harmful. Teach them how to use it properly. Warn them strictly to rub till the alcohol dries. Store the container out of their reach or they will be tempted to use it time and again either for the smell or for the cold feeling it gives for few moments before getting dried.

Wash your way to health

Though soap may not kill every virus it comes across, it definitely decreases the viral count and brings it below the infectious threshold. It is neither time consuming, nor does it take any major effort. Wash your hands often to fall sick less often.
