Mental Maths Activities That Are Beneficial

Posted on by

Considered a complex subject, most students find it intimidating and for most of them, as they age, it becomes more complicated. Though this is the case, it is an important part of life as it equips them with the necessary skills to face real life.

Easy Answers
Mental maths should be introduced from kindergarten grades to students who have a lower capacity of understanding maths. This should be done with easy to answer questions. If it is in a class setting, then the students should be presented with simplified math equations and the first one to get the right answer should shout it out. As this progress, it will eventually reach a point where the entire class shouts out the right answer as a team. As they age and get more equations correctly, then more complex math should be introduced. In this instance, students can use time tables, basic algebra and division facts. For instance this could be something that Y plus four equals 10 and the students should answer what Y is.

Complex Math
A large percentage of maths used in day to day life is mental math tricks. For instance, someone working at a store should figure out what 60% of $20 is, a driver is supposed to figure out how many hours he will drive to cover a 230 mile trip among others. This proves that math is an important part of life and as such, it is ideal to ensure that students solve mental maths equation every day. However, when carrying this out, it is important to ensure that it is age appropriate. For seventh graders 60% of $ 230 is ideal while for fourth graders 10% of 100 is appropriate. Students should be given the time to read the equation and work it out before providing the answers.

Story Problems
This is another important mental maths activity to indulge in. It should be on situational stories and students should be encouraged to work them out mentally. Also known as multi-mental math they are the best. This is attributed to the fact that they require more thought for the answer to be processed as well as mimicking the manner in which maths is used in real life situations. However, it is important to outline the equation in a manner that is easy to understand. Though challenging, these simple mannerisms when employed in the right manner, help students develop an instinctive accuracy handling mental maths.

Psychological Effects Of Facebook

Posted on by

Some time ago, there were reports about the signs of people addicted to Facebook or other social networking sites, for example, you change the status of more than two times a day and comment on the industrious friends status changes. You also diligently read the profile of a friend of more than two times a day even though he was not sending messages or to tag you in photos.

A recent report from The Daily Mail says, addicted to social networking sites like Facebook or MySpace can also be harmful to health because it triggers people to isolate themselves. The increasing isolation of self can change the way genes work, confusing the immune response, hormone levels, arterial function, and damage to mental performance. This is indeed contradicts the aim of the establishment of social networking sites, where users promised hereafter to be able to find old friends or comment on what is happening on your current partner.

A relationship starts to become dry when the individual no longer attend a social gathering, to avoid meeting with friends or family, and prefer to linger staring at the computer (or phone). When finally interact with peers, they become restless because of the separated from his computer.

The user eventually drawn into an artificial world. Someone whos friends are mainly foreigners who just found on Facebook or Friendster will find it difficult to communicate “face-to-face”. This behavior can increase the risk of serious health, such as cancer, stroke, heart disease, and dementia (senility), thus by Dr Aric Sigman in The Biologist, the journal was released by The Institute of Biology.

The meeting is face-to-face has an effect on the body that are not visible when sending e-mail. Levels of hormones such as oxytocin which encourages people to hug or interact with each other to change, depending on whether or not near the user. Several genes, including genes related to immune system and response to stress, act differently, depending on how often a person does social interaction with others.

According to him, the electronic media is slowly destroying the ability of children and young adults to learn social skills and reading body language. One of the most frequently posed changes in daily habits British population is a reduction in interaction with their peers in the number of minutes per day. Less than two decades, the number of people who say that no person can be consulted on important issues to be redoubled.

Physical damage is also very possible. When using the mouse or press the keypad phone for hours every day, you can experience injury repetitive pressure. Back disease is also common in people who spend a lot of time sitting in front of the computer desk. If at night youre still busy commenting your friends status, you also lack the time to sleep. Loss of sleep time in a long time can cause prolonged drowsiness, difficulty concentrating, and depression of the immune system. Someone who spends his time in front of the computer also will rarely exercise so addicted to this activity can lead to a weak physical condition, even obesity.

No wonder if Dr Sigman worried about the direction of this problem. Social networking sites should be a flavor of our social life, but we found very different. In fact these sites do not become a tool that can improve the quality of life, but rather a tool that makes us the wrong direction, he asserted.

However, if your Facebook activities are still just sign in, confirm friend requests, and then sign out, it seems you do not have to worry about would be exposed to the risk of cancer, stroke, and even suffering from dementia.

Group B Strep Leaves Baby With Quadriplegia And Mental Retardation After Pediatrician Missed Signs

Posted on by

A Group B Strep infection can have severe consequences on a baby and can develop and cause injury suddenly and quickly doctors generally agree that antibiotics should be administered as soon as a baby shows signs of infection rather than wait for test results which can take 48-72 hours. If test results later come back negative, antibiotics can be stopped. Failure to recognize the signs of infection or to treat them immediately with antibiotics may result in medical malpractice.

Consider, for example, a reported case in which the baby’s mother had tested negative for Group B Strep during the pregnancy and neither the mother nor the baby showed any of the risk factors for neonatal sepsis (such as preterm delivery, rupture of the membranes lasting longer than 18 hours prior to delivery, and infection of the placental tissues and amniotic fluid).

The pediatrician was present in the delivery room. Within three hours of being born the baby started experiencing respiratory distress, had problems feeding, and his extremities started showing diminished perfusion (which can lead to decreased tissue oxygen delivery).

The pediatrician was called two times by the nurses about these developments. The pediatrician ordered pulse oximetry but did not examine the baby. Pulse oximetry is a noninvasive method of monitoring the oxygenation of the baby’s hemoglobin. The results were normal as were the results of the CBC and urine bacterial antigen tests ordered by the pediatrician after the baby’s birth. Over the course of the next 11 hours after the initial onset of symptoms, the baby’s respiratory and feeding problems seemed to resolve but the perfusion problems did not change.

The pediatrician claimed to have examined the baby 14 hours after birth. There was no record in the chart of the pediatrician conducting a full examination of the baby. There was only an entry indicating that the baby was normal in all respects, active, pink, alert and feeding well. The pediatrician then left the hospital.

Entries in the chart over the course of the next 12 hours documented that the baby’s perfusion problems continued. Then, 26 1/2 hours after being born the baby again developed respiratory and feeding problems. The staff called the pediatrician approximately 1 1/2 hours after these symptoms returned.

The pediatrician immediately returned to the hospital, diagnosed the baby with septic shock, and transferred him to the Intensive Care Unit. The baby required resuscitation. He was transferred five hours later to a medical center where he could receive more specialized care and remained there for an extended stay.

The baby had suffered from meningitis due to a Group B Strep infection. The meningitis, in turn, resulted in quadriplegia and mental retardation. Had the pediatrician administered antibiotics prior to leaving the hospital, the baby would not have developed meningitis and would not suffer from quadriplegia or mental retardation.

A lawsuit was filed on behalf of the baby and his parents. The case went to trial where the plaintiffs presented evidence that the pediatrician (1) should have conducted a full sepsis workup 3 hours after delivery, when the baby first started showing symptoms (2) should have immediately started the baby on antibiotics and (3) should have left clear instructions for the nurses to contact him immediately of any change in condition. The jury returned a verdict in favor of the plaintiffs and the law firm that represented them reported the case then settled for $1.0 Million, the policy limits.

This case illustrates the importance of reacting quickly to signs of infection in a newborn. While the pediatrician took the position that the initial respiratory and perfusion problems were explainable as side effects of issues other than infection, that the feeding problems had resolved before he left, and that the test results were negative, the fact remains that the baby did have a Group B Strep infection and that early administration of antibiotics, as most doctors would recommend, would have prevented his lifelong disabilities.

The flat wart is a viral skin disease. Its pathogens are like common warts. It is a skin neoplasm caused by infection of papillomavirus HPV3 and HPV5. The virus is mainly infected by direct contact. It can also have indirect infection through contaminated objects. Its performances are dispersed distribution with soft nature, smooth top, miliary size and pale brown color. It is above the surface of skin papules. There are many ways for the treatment of flat warts, but the effectiveness has not been quite sure.
