Health, Disease and Case Study

Health: The state that your body is in, all the systems are working properly, physically and mentally, and the body is active. The general condition of the person.
Disease: Something that disturbs the natural functions of the body, some being caused by a substance entering the body and others by genetics.

Different types of diseases:
- Lifestyle diseases: Diabetes, obesity
- Social diseases: AIDS, Syphilis, Herpes
- Genetic diseases: Down syndrome, Dwarfism, Hemophilia, Breast Cancer
- Infectious diseases: Chicken pox, Influenza, Cholera
- Microbial diseases: Micro plasma
- Environmental diseases: Minamata disease

Minamata Disease (environmental disease):

Minamata disease is a neurological syndrome which affects the nervous system. It is caused by mercury poisoning and some of the symptoms include:
  • Ataxia
  • Numbness in the hands and feet
  • Muscle weakness
  • Vision problems
  • Damage to hearing and speech
In extreme cases some symptoms that can occur are:
  • Insanity
  • Paralysis
  • Coma
  • Death
The disease can be passed to a baby in the womb as a foetus, in a congenital form. Children born to poisoned mothers can be born blind, dead, with mental retardation and gnarled limbs. It was first discovered in Minamata city, Japan. It was caused by toxic pollution released from a chemical factory.


Pandemic 2 Results:


Bacterium
Background info: The disease is drug resistant and can mutate quickly and unexpectedly. It is fairly lethal and somewhat visible because of the sores, diarrhoea and nausea.
Cause – pathogen (Bacteria)
Incidence: towards the end of the game there were 85747364.797 infected people a day, and so far 167978670 deaths.
Risk factors: Health complications, hypersensitivity, dementia
Symptoms (sneezing, coughing, fever, sores, diarrhoea, nausea, pulmonary edema, dementia, hypersensitivity and kidney failure)
Treatment (vaccine)‍
Control (closing shipyards, airports, schools, transits, borders, hospitals, extermination of insects and rodents, enforcing curfews, martial laws in effect)
Prevention – (closing schools and hospitals, closing airports and shipyards)
Prognosis - The areas of the world that were not affected by the disease were Australia, Japan, New Zealand, Greenland and Madagascar. In the beginning the disease spread quite slowly but when I added new symptoms the disease spread quickly. Scientists and medical practitioners attempted to create a vaccine but once it was deployed, it didn’t have the desired effect.
I predict that if I continue the game the disease will eventually wipe out a large amount of the population of the severely infected areas, such as, India, South & North Africa, and Europe.

Hi there Bec,
You`re off to a really good start here.
You can add all homework where possible, eg. such as the Malaria One World practice homework.
Good analysis of the game above,

MALARIA - ONE WORLD



Global issues related to the spread of Malaria.

  1. Global Warming



  1. It infects 300 million people worldwide.



  1. 40 % of the world are at risk of being infected.


SOCIAL



How can social groups (communities, families, friends, neighbourhoods) act to reduce the spread of Malaria?

They can help by raising awareness and money to send to charities to help fight Malaria.

Request international aid for nets support vaccination research etc.



How are social groups limited in the way they could help to reduce the spread of Malaria?

They can’t actually go out and stop Malaria. Social groups can only help if they have funding and enough money. They need to have volunteers and people that have enough time to help out.



How do social groups benefit from the control of Malaria?

Social groups can make a name for themselves helping with the control of Malaria. They may be able to grow their organization so they can help out in other areas. People that work for an organization can have a fulfilling job.



How are social groups harmed by the spread of Malaria?

Social groups could catch the disease themselves.

_

ECONOMIC



What are the financial advantages of reducing the spread of Malaria?

Families can save money on medication.

Government can put more money into healthcare, into communities and research on other diseases and issues.



What are the financial obstacles to reducing the spread of Malaria?

Distribution and transport.

The medication could be expensive.

Need to pay nurses and other medical experts.

The vaccine needs to be very widespread.



POLITICAL



How can international, national, state and local governments act to reduce the spread of Malaria?

Use tax money to support research for Malaria.

Raise awareness. National governments can provide support for local governments trying to reduce Malaria.

Can work together to fasten the processes that are involved in reducing the spread of Malaria.

Providing medical assistance to the locals.





How are governments limited in the way they can help to reduce the spread of Malaria?

Don’t have an infinite amount of money.

Already have problems they need to solve.

There may be corruption in the government.

The government may not have the support of its people.







ENVIRONMENTAL



How is the environment harmed by the spread of Malaria?

The environment becomes contaminated with Malaria through mosquitos and monkeys.

Not very hygienic when disposing of bodies.

Labs and other research facilities for Malaria may not be environmentally friendly.



How does a healthy environment help to reduce the spread of Malaria?

A healthy environment with less heat caused by pollution means that people won’t attract as many mosquitos.

In a healthy environment the mosquitos wouldn’t reproduce as fast.

Landfills aren’t overflowing.



What does an unhealthy environment bring about an increase in the spread of Malaria?

Malaria strives in unhealthy situations as it spreads through contaminated mosquitos that are most prominent in regions with less or no medical help and hygienic necessities such as showers, toilets, clean water etc.

People are less able to get medical assistance when infected and so they could then affect other people.

An unhealthy environment would only worsen the symptoms of Malaria making it a more painful ordeal.



CULTURAL



What are some cultural beliefs that help to overcome the spread of Malaria?

Tribes can perform ceremonial dances that help to keep the disease away.

Some traditional herbal remedies that are within tribes or cultural groups may help with the symptoms of Malaria.

Some cultures may have specific methods to keep mosquitos away.



What are some cultural beliefs that limit efforts to overcome the spread of Malaria?

May refuse to accept medical help.

May think they should just overcome it, a test of manhood.

May not want to accept help from other cultures than their own.



ETHICAL



How do laws help to reduce the spread of Malaria?

May make it compulsory to get a vaccination.



How are laws limited in the way they can reduce the spread of Malaria?

People may reject the vaccination due to their own personal beliefs.



MORAL



How do people’s beliefs about what is right or wrong help to reduce the spread of Malaria?

People may believe that it is unjust to let people die of Malaria.



How do people’s beliefs about what is right or wrong limit efforts to reduce the spread of Malaria?

People may think that it’s not their position to try and “play God.”

Hi Bec,
I've rearranged the headings in your table to put them in the correct order for referencing.
Great work adding the in-text referencing also.

Homework July 17th 2012



Gears are usually wheels with teeth and have been used by human cultures for centuries.

Common examples of uses of gears:
  • Used in clocks
  • Cars
  • wind up toys
  • oil rigs

Gears can be used to magnify and/or change the direction or speed of movement.

Driving gear: The gear that inputs the force or movement.

Driven gear: The output of the force or movement. This gear is moved by the driving gear.


Gears can be joined through physical contact and also through a chain or belt. Gears joined by contact always move in opposite directions. Gears joined by a chain or belt often rotate in the same direction. This is because the belt has the ability to transfer the same rotary motion.

Gears on a pushbike are used as force and distance magnifiers. The gears that are used a force magnifiers work on the basis that the driving gear (effort force) is smaller than and transfers motion to the driven gear (load/resistance force). The large wheel moves more slowly but with more force. The distance magnifiers of a pushbike work on the basis that that the driving gear (effort force) is larger than and transfers motion to the driven gear (load/resistance force). The load moves faster but with less force. This is known as a distance or speed multiplier.

Gears used as distance magnifiers increase the speed of a pushbike as they involve moving the load faster to increase distance. The load wheel moves faster therefore rotating more, therefore covering a larger distance.
