Women’s Health Research

Both women and men share similar health challenges, but the differences are such that the health of women deserves particular attention. While there are many commonalities in the health challenges facing women around the world, there are also differences due to various conditions in which they live. I think it is very important for women to have access to knowledge related to their own health, not only about the reproductive system because they are going to a mother and wife, but about all aspects of her body. Therefore this will be amazing research to scrutiny the women’s health in all aspects, and especially seeing the different perspectives towards the women’s health system in Cambodia. My aim is to 1, Determine the current health services for women in the rural areas in Cambodia and what they are lacking. These include: (a), the area of they are living; (b), the income/poverty around their area. 2, Dictate the current women and girls health in Cambodia; major health concern, establish the needs for women and girls based on their service which also could link to their knowledge of their own health.


Valence Shell Electron Pair Repulsion

  • Valence Shell Electron Pair Repulsion – allows us to predict the shape of molecules to better learn their properties (they are 3-D versus 2-D Lewis structures)
  • Molecules will assume arrangements that minimize the repulsion between the electron pairs around the central atom. 

VSEPR Models: Two bonded pair

VSEPR Models: Three bonded pairs of electron

VSEPR: Four bonded pairs of electron

VSEPR: Five and Six bonded pairs of electron

Polarity – based on the shape of the molecule

    • In a polar molecule, there is a net unequal sharing of the electrons.
    • If two dipoles are at angles they will NOT cancel out.
    • In a non-polar molecule, there is a net equal sharing of electrons.
    • If two dipoles are in opposite directions they will cancel each other.
    • This can be determined by looking at electronegativity and shape.





Heterogeneous vs Homogeneous mixtures

  • What is the different between Heterogeneous and Homogeneous mixtures?
  • Three phrase or states of matter gas, liquid and solid.

Homogeneous – a mixture that is dissolvable in each other

Heterogeneous – a mixture that is separated from each other


  • Homogeneous mixtures examples
    • Air
    • Sugar water
    • Rainwater
    • Vodka
    • Vinegar
    • Dishwashing detergent
    • Steel
  • Heterogeneous mixture examples
    • Cereal in milk
    • Vegetable soup
    • Pizza
    • Blood
    • Gravel
    • Salad dressing
    • Oil with water
    • Mixed nuts
    • A bowl of colored candles
    • Soil
    • Ice in Soda
  • Heterogeneous mixtures are more common than a homogeneous mixture


Healthcare in Cambodia – One2One

On August, 31st, 2018, our Healthcare exploration visited MoPoTsyo to gain insights into healthcare and healthcare perspective in Cambodia. MoPoTsyo—a shorter term for Patient Information Centre—is an NGO that works with patients with chronic diseases, especially diabetes. We were there to talk to Dr. Maurit. He was a really fun man to talk to. He took us through mini biology lessons and explain different diseases and condition. From his talk, we learned that diabetes is not a disease, rather it a condition where the person is unable to produce insulin (type I), or unable to use their insulin effectively (type II). You might be wondering what is insulin is, well, it’s just a fancy name for a hormone that helps your body to regulate its sugar level. Back to where I trailed off, not only did we talk about Cambodia, we also discuss the sugar credit (in Thailand) where the tax paid by food production company is proportional to the sugar content of their product and various food scandal. Then, we talked about the improvement(s) Cambodian public hospitals can make, and learned about MoPoTsyo’s work. What they do is really cool, they offer blood testing service and education program. They also a longer training program, where people were taught about diabetes, and later take a test to ensure that they are qualified to teach their peers and raise awareness of diabetes.

Engineering Biography

Hedy Lamarr

Born: November 9, 1914

Died: January 19, 2000 (age 85)

Citizenship: Austria (1914-1953), United States (1953-2000)

Occupation: Actress, Inventor

Hedy Lamarr was born on November 9, 1914. She was an Austrian-born American film actress and inventor. Lamarr won a beauty contest in Vienna at the age of 12. As a child, she showed an interest in acting and was fascinated by theatre and film. She became a film star from the late 1930s to the 1950s. Her best-known films are Algiers, Boom Town, I Take This Woman, Comrade X, Come Live With Me, H.M. Pulham, Esq, and Samson and Delilah.

At the age of 18, Lamarr married Mandl. Her marriage eventually became unmanageable, and she decided to separate herself from her husband. She described her husband as an extremely controlling husband who strongly objected to her acting career. She even claimed she was kept a virtual prisoner in their castle home.  After leaving Mandl, she met Louis B. Mayer, head of MGM. He brought her to Hollywood in 1938 and began promoting her as the “World’s most beautiful woman” and she gets famous ever since.

During the World war II, Lamarr wanted to join the National Inventors Council, but the NIC member told that she could better help the war effort by using celebrity to sell war bonds. Because of her participation, there were many war bonds purchases during that time. Throughout her entire time in the film industry, Lamarr enjoyed her biggest success playing Delilah the most. The film was the highest-grossing film of 1949 and also won two Oscars.

Besides working in the filming industry, Lamarr also worked in her spare time on various hobbies and inventions. She improved traffic stoplight and a tablet that would dissolve in water to create a carbonated drink. The beverage was unsuccessful but later on, in 1997, Lamarr received the Electronic Frontier Foundation Pioneer Award and the Bulbie Gnass Spirit of Achievement Bronze Award, given to an individual whose creative lifetime achievements in the arts, science, business, or invention fields have significantly contributed to society.

Lamarr died in Florida, on January 19, 2000, of heart disease, aged 85. She was given an honorary grave in Vienna’s Central Cemetery in 2014. Despite the fact that Lamarr was an actress, she was also the first woman to receive the invention Convention’s BULBIE Gnass Spirit of Achievement Award, known as the “Oscars of inventing.” This amazing history should be spread and hear by everyone because Lamarr, an actress, and woman had broken the world stereotype by inventing the “secret communication system” that we are now using every day.

Last but not least, the three characteristics that help Lamarr reached her goals must be persistence, patience, and positivity. Lamarr was not just a pretty actress, in addition, this Lamarr seems to play an important role during and after the World War II broke. She wanted to solve the problem of communication at that time, but her first attempt wasn’t a success due to sociocultural discrimination. I understand that sometimes there are people that are going to say “no” to what we want and need but successful people do not give up, so did Lamarr.

Completing the Square

Completing the Square in Circle Equation

Circle of equation : (x – h)2 + (y – k)2 = r2

Center point :  (h,k)

Radius: r

To find the standard form of the given circle equation by factoring we can use a technique called completing the square. This will help us to quickly identify the circle’s center point (h,k) and the radius.

(Please click on the picture to see it clear)

Center Point and Radius

Keep in mind that the factored form of a circle equation reveals the center point (h,k) and the radius. In the above example, (3, -4) is the center point and the radius is the square root of 26.

Photography inspired poetry

Students are required to write three different type of poems such as the Found poetry, Photography poetry, and the Metaphor poetry. The poems can be written in any perspective reflected on any books that students had read. Here is my Photography poetry that was written in a perspective of a seed growing at the dump. I was inspired by this lovely picture of a poor little boy scavenge at the River of the Victory dump which best known as the largest municipal dump in Phnom Penh.

I’ll grow out of anger,

I’ll grow out of fear,

I’ll grow out of where YOU, people called dump,

To prove you I’m massive.


I water myself,

Night and morning with my tears,

And I grow both day and night,

Till it bore an apple bright.


You once called me a groundless seed,

You trapped me miserably,

But you never knew that this browny-little seed,

Seeks its own nutrition, out of this toxicity.


(Deep breath)….

And now, maybe I’m not a beautiful tree.

But, I’m not alone.

Thanks to this municipality, or this yard, or this large, awful, stingy, rubbish, landscape. 

You gave me the moon, the star, the sun, the cloud, and you proved to me that I’m no longer the unwanted seed.

Bonjech Ponler

“Bonjech Ponler” is a title of a 4 minutes songs that had created by the Human Agency Company collaborating with the Liger students and Phare Ponleu Selpak. It was my pleasure to be selected as the fellow in a film production in a purpose of introducing Cambodia culture to the whole world. There were eight students selected for this two weeks project which required everyone to travel down to Battambang province to meet all of the crew and actors there. Human Agency is a company who “produce content-powered platforms for the most recognized brand names on the planet.” They’ve done many videos, their crews are from all over the world and their requirement is to finish the film in just two weeks. It was fun working with them; we did so many activities such as planning idea, designing scenes, producing music, writing song, filmmaking and interview many people.

Maker Faire 2018

Maker Faire is an all-ages gathering of tech enthusiasts, crafters, educators, tinkerers, hobbyists, engineers, science clubs, authors, artists, students, and commercial exhibitors. All of these “makers” come to Maker Faire to show what they have made and to share what they have learned. At the early of March, I had an opportunity to present my technology fashion project at this event. Click here to read more on my project. Furthermore, I got the chance to network and observe the craftiness from a lot of Cambodians, which could imply that Cambodians are intelligent, talented, and creative. It’s satisfying to see that we are developing in the STEM areas, I can’t wait to see the development, yet to come.

Rabies in Cambodia

Rabies is a viral disease that causes inflammation of the brain in humans and other mammals. Rabies transmission can occur through the saliva of animals and less commonly through contact with human saliva. In Cambodia, there are 600,000 dog bites per year and 60% of them are children under 17 years old. Institut Pasteur du Cambodge, is one of our partner had come out to our school and did a short presentation about Rabies. It is very impressive to meet them as well as knowing that they are the only organization that give out Pre- and post-exposure vaccination to people all around Cambodia. In addition to this, we also meet the other two organization which are Animals Rescue Cambodia (ARC) and Phnom Penh Animal Welfare Society (PPAWS), whose are working closely with animals. We got a chance to travel down to Mondulkiri with PPAWS and held a Rabies campaign there for two days. We gave out rabies vaccines to dogs and cats as well as desexed them in order to keep control of their population. On the 7th of February our students with ARC, held another campaign nearby to provide a free vaccination to dogs and cars. We did around 170 dogs & cats in totals for just one day which is a really good sign for us.

Vaccine before dog/cat bite

  • Dose 1: As appropriate
  • Dose 2: 7 days after Dose 1
  • Dose 3: 21 days or 28 days after Dose 1

Vaccine after dog/cat bite or scratch

  • Dose 1: As appropriate
  • Dose 2: 3 days after Dose 1
  • Dose 3: 7 days or 28 days after Dose 1
  • Dose 4: 21 or 28 days or 28 days after dose 1
