Global Risk Report 2

This blog is about the global report base on the facets that may happen which the authority list in different risk: 
1.     Fragile Societies under Pressure.
Base on the report, the fragile of societies is increasing now and one of the major drivers to the fragility of societies is rising socio-economic inequality within countries. Therefore, the question that I come up here is which countries highly in “rising socio-economic inequality” condition?
Well, I hardly found the answer for this question, but there’s an article from the internet. It reports on inequalities in mortality between two broad socioeconomic  between men and women in 6 countries, Finland, Sweden, Norway, Denmark, England/Wales, and Italy (Turin). After that the report shows that the inequalities in total mortality have increased in all six countries. Therefore, I might conclude that socio-economic inequality is happen all around the world.


2.     Preparedness at the Regional Level Is Different
In the report, they mention about the geopolitical risk, saying that it can also impacts on other risks. So the question is how geopolitical risk cans impacts on other risks. From an article I read on the internet, they say that geopolitical risk is in the top 10 global risk and when people focus on that risk, it make a shift from the focus on economic risk that prevailed between 2007 and 2014.

3.     Economic Risks: Out of the Spotlight?
In this report, there are paragraph that mention low interest rates have also fuelled the risk of asset bubbles. So my question is what are asset bubbles? The asset bubbles are created when the prices of asset like house, stocks, gold become over-inflated and rise quickly over time. It's a bubble when investors bid up the price beyond any real sustainable value.


4.     Environment – High Concern, Little Progress
The report mention the nexus of food, water energy and climate so I kind of wondering the relation of these substances. So the question I come up for this article is how food, water, energy and climate relate? Later, in the article, they list some issues that are relate to the climate like overfishing, deforestation and the inadequate management of sensitive ecosystems such as coral reefs are increasing the stress on food and water systems.
5.     Technological: Back to the Future
With high technology come more troubles. The article had mentioned about the “Internet Thing” also entail new risks. One of the risks they mentioned was security risk. They’re saying that the current Internet infrastructure was not developed with such security concerns in mind. And my question is what are the other risks that the “Internet Thing” might cause? To answer this question, I have taken a look using the “Internet Thing” to find out what risks it might bring. The Internet can also be considered a dangerous place since it can be access everywhere. Therefore, beside the security risk, which can affect to your business’ document, knowing unclearly who you are doing business with on the internet also bring risks like cyber criminals, bullies, and corrupt businesses.

6.     Preparedness at Regional Level is Different

This article states that each region has to prepare to handle their problem. For example, North America identifies failure/shortfall of critical infrastructure, large-scale cyber attacks and failure of climate-change adaptation as the three risks for which it is least prepared. Sub-Saharan Africa is considered least prepared for infectious diseases and unemployment… Moreover, there is a figure on the article point out that the East sides of Asia, where I live, have to prepare for interstate conflict. So my question is what some interstate conflicts that we have to prepare are? In my opinion, the conflict that might lead to war between countries is the important interstate conflict that we have to prepare. Take the conflict between Vietnam and China about the 981 rig for an example. That conflict might easily lead to war if one side didn’t abdicate. However, a question how to prepare for such an important interstate conflict is a hard question to answer. 

Motivation

Hi, my name is Duy and today I'm going to tell you a little bit about myself. I'm a 11th grade student study in an international school, By the time I'm writing this blog it's almost one o'clock in the morning. The other friends of mine must be in bed at this time. So why I have to do this? What is my motivation for doing this.

The answer for that is my grade. Yes, it's nearly the end of the final semester I my grade will determine whether I'll pass this class or not. Unlucky, I'm at the edge of failing and there will be tones of problems happen with my family if I fail this class. So that is the motivation for me to keep doing this blog.

Motivation can understand through the dictionary is an external aspect cause people to be continually to do a job, a role or a subject, to make an effort to attain a goal. Everything we do in this world needs a motivation. There are a lot of theories about motivation and one of them is the Maslow's Hierarchy Theory. Maslow has created the need of hierarchy, and they were listed in 5 levels, from low-to-high order. Every single human has to satified with lower needs before moving to higher-needs. Base on Maslow, people are all trying to reach the highest level. Therefore, they have to satisfy the lower-level and that is their motivation.

Like I mentioned, everything we do need a motivation. This theory of mine can also apply to fix some of the 21st century issues. What motivate us to fix an issue? Take nuclear energy for an example and you want poor people, hunger to pay attention on that problem. Well, they might not even care of it because they’re too hungry. Their lower level needs of the Maslow’s Hierarchy of them aren’t satisfied. Therefore, they won’t able to reach the top-level: problem solving. Because of this, to motivate a person to take a part in fixing the world’s issues, you have to make sure their lower-level needs are satisfied.

Nuclear Energy

What is nuclear energy?
The energy generated during the combustion of oil, coal, gas and energy generated when explosives detonated called the energy generated by the chemical reaction, energy is generated by the movement of electrons orbiting nuclear. Atomic energy is the energy produced during the nuclear fission or nuclear fusion.



How nuclear energy happen?
In the atomic nucleus, the nucleons (protons or neutrons regardless), at very little distance, will attract each other very strongly. Through this link energy that protons and neutrons together in the nucleus unstable. When nuclear fission or nuclear fusion, the binding energy of the nucleus will be released called atomic energy.

Nuclear energy factory is the factory that create power and record the energy from nuclear power. However there is possibilities that accidents will happen. On 26.04.1986, the accident at Unit 4 of the Chernobyl nuclear power plant from the capital Kiev Ukrainian republics of the former USSR is about 130 meters north.
The reactor has a capacity of 3200MW using graphite as retardant and water quality thermal load is light. This is a particular type of reactor developed by Russia.
The accident occurred while testing to stop power supply from outside, to see the rotation inertia of the turbine, the generator will gain much power.
From a wide range of errors, such as operating personnel actions violated the principle of operation, making the device automatically stops the oven does not work, the priority for the completion of the test, to deviate from the plan, reactor running at low power is unstable, then violated the principle of the control rods. Therefore, the reactor power increased rapidly, overheating fuel, steam generated intense, leading to damaged pipe pressure, part of the reactor and oven building.
According to the authorities, 31 people died in this accident (which, one person died from burns while extinguishing the fire and another was missing) and 203 people hospitalized due to acute radiation exposure. Because the reactor and the building was destroyed, and so the radioactive material inside the reactor leak out. As soon as the accident occurred, around 135,000 residents within a radius of 30 km from the plant to flee.



Fixing these problems might lower the chance of  facing the accidents:
- The defects of the management system of the factory
- The functional defects of sealed radioactive materials
- Violates the principle of operation, operating personnel lack knowledge
