Current Event- Removing Plastic from the Ocean

This video is a guy who came up with an idea to remove the plastic from the ocean. His idea is to implement something that attach to the seabed, and then let it clean by itself. This system is very passive- don’t need to do with machines and don’t require a lot of people because the sea will clean by itself. I learn that because of the current, the plastic will concentrate in the same areas. So, it makes it easier to clean.

I think that this is a very good idea to make our world become a better place for every organisms to live in. Before plastic fragment into micro-plastic, we should clean it by using his idea. If we don’t care about this, there will be millions pieces of plastic in the ocean and it will make it harder to maintain it.




Current Event -South African Girls Protest for Their Rights

There is prestigious high school in South Africa named Pretoria. This school cost about $2000 for every girl to go to learn. Even though, those girls can get high education, there are still problems about racism. Girls are not allowed to wear Afros because they think that it is untidy and not appropriate with school uniforms. So, many girls come together to protest and even their parents and people in the community. According to the school: “All hair styles should be conservative, neat and in keeping with the school uniform.” This clearly show that just because of the hairstyles, girls have to skip school and come to protest for their rights.


Humans of Cambodia

In this Expertise, I and my team tried very hard to interview Cambodian as many as possible. During our interview, we recorded what they were saying and take pictures of them. After that, we listened to their audios and note down the most interesting parts about them. We had to go through many processes because we interviewed them Khmer. So, we had to translate it to English, word by word, based on the recording. We tried to be as accurate as possible about our translation. Our goal in this Expertise is trying to make a blog and let other people to learn more about our people daily life activities, life condition, and what are their challenges in their life, etc.

CPR (Help Your Life)

In my school, most students and I had chosen one topic to learn about it. Also, you just don’t choose any topic to learn, but you chose the topic that you are passionate and curious about. So, I chose CPR because I am interested in it and I really want to help other people when they have a heart attack. Every Tuesday from 12:40 – 2:00 pm I had to do a lot of research to complete this topic. I spent about one month to accomplish this, but in every week I only did on one day. So, in total I only did this topic in four days. So, if there is any confusion or questions or you think it is wrong, you can comment at the bottom of the page.

What is CPR?
CPR (Cardiopulmonary Resuscitation) means a way of trying to save someone’s life who has stopped breathing and whose heart has stopped beating etc,. There are two ways to do CPR: mouth-to-mouth or chest compression.

What is the background behind CPR?
In 1956 Peter Safar and James Elam invented mouth-to-mouth resuscitation. Then in 1957 United States military think that mouth-to-mouth resuscitation is very helpful, so they take that to teach their military incase their heart has stopped beating. Since 1960 CPR was developed. In 1981 Dr. Friedrich Maass performed the first chest compression in humans.
History about CPR 

What is the purpose of CPR?
The main purpose is to restore partial flow of oxygenated blood to the brain and heart. If the heat stopped beating that is mean no blood are moving, so the blood can’t bring oxygen to your cell. If your cell don’t get enough oxygen you will die, so someone have to do CPR to you because you are really need oxygen to be able to breathe.

How to do chest compression?
-hands are straight on the center of the chest
-one hand cross over another hand (straight hands)
-use your palm to push down 2 inches deep
-100 compressions per a minute

-Check if the scene is safe
-Make sure that person lay on a flat surface
-Tap the person’s shoulders to check for response “ARE YOU OK?”
-If no response, shout for help
-If someone responds – have them call to emergency number
-Check the pulse for no more than 10 seconds (at neck or hand)
-Begin to do CPR
-Put hands on breastbones
-Arms straight above the chest
-Push hard and fast, 2 inches deep
-Repeat compression until AED1 arrives

Why they stop doing mouth-to-mouth CPR?
In 2010, (International Liaison Committee on Resuscitation) studies and found that breathing (mouth-to-mouth) wasn’t necessary. Also, it is help less than chest compression and it is too complicated to do it.

Important Note
If you get to train, you can do 30 compressions with two breathe, but if you are not the trainer, better to do only chest compressions.

You don’t need to do CPR to the person that doesn’t have heart attack. If you tap a person, and then they say I am okay, they you don’t need to give CPR to them.

Shared with Other People
On Friday 11, September 2015, there were a water safety presentation at Olympics Stadium pool in Phnom Penh. At there, they showed us how to rescue drowning people. One of the best part of the field trip was when I shared my CPR to some students that were there. I also met one woman who was presenting about CPR to the kids. So, I joined with her and help her to translate to the kids.

Also, there was a group that tries to dive underwater to find bomb that were left under the water. They found one bomb underwater in 2015 May, then they took it out from underwater. They noticed that the bomb was dropped down when America and Vietnam War.

Technovation is a global competition that inspires every girl to join and create an app that can help to change their country. Liger school picked 13 girls to join this program and I was the one of them too. The location that we worked at was DI (Development Innovation) in Phnom Penh (main city). We had three weeks to complete this competition and we did it every weekend. At DI there were not just Liger school girls that joined, we had some girls come from other schools too. So, in all we had five teams (3 teams of all Liger and 2 teams of other schools). For my team, we had five members.  The first week, our mentors told us to think of the ideas that we can help to change Cambodia. I joined with a team of three girls and we came up with the idea of helping farmers and customers. We presented our idea to other girls and to our mentors. A lot of people voted for us, so we had to find two more girls to join in our team. So, two more girls came to our team. We discussed in a team and we had to come up with the name of the team and the app name. Our team name was Ligeek and our app name was ImEx (stands for imports and exports). The second week our mentors introduced us to some basic coding that we will code our app in there. We used appinventor2 to code our app. For my group we divided into two groups. One was business plan group and the other was coding group. I was in business plan group because I like to write and I hate coding. From week three until week 10 we just coded and wrote something about our app into our business plan. In those weeks, we had to do some surveys in order to have some proof that farmers are really faced with those problems and also customers. In week 11, we made two videos, one video was the pitch video and the other one was about app demo. In the last week, we had to submit our app resources and everything that we had done to our judges in the U.S.A.

After two weeks (est.)  Technovation (judges in U.S.A) sent us back the results if we won this competition or not. We were really proud of ourselves because my team was the semi-finalist team representing the region of Asia, New Zealand, Europe and Australia (middle school).  But we were a little bit sad because we weren’t the finalist team, but we still are proud of ourselves that we were the semi-finalist team.

Now, in my school (Liger) we still are continuing to develop our app. Even though we are not the ones that are in the competition, we are still  making the app in order to help change Cambodia. So,  if you are a coding teacher or an expert in that, maybe you can help us to make this app run. I hope that one day there will be a mentor or teacher that can help us.
