Japan's Economic Growth

We are all aware that Japan is a very developed country nowadays. Japan is one of the leading countries not only in Asia but in the whole world. But the question is, How did Japan able to attain this?

Several years ago, Japan had their rapid increase in their economic growth. Their average economic growth during that 1960s to 1970s is around 7.5%. But this rapid grow leads to different environmental crisis and different diseases, these are the Itai-ita disease, Minamata disease and the Yokkaichi Asthma.



First of all, the Itai-Itai disease or it hurts it hurts disease. This disease is cause of cadmium poisoning. It leads to kidney failure and bone softening. Due to cadmium poisoning, fishes in the river died. The water in the river became contaminated and this is the one being use to irrigate the rice. And because of this, the rice absorbed heavy metals. And people were able to eat these contaminated rice. All of these happened because of the mining companies.

Another disease that arouse in Japan is what we call the Minamata Disease. This disease is cause of Mercury poisoning. During the 1956, it was the Chisso Corporation's chemical factory that releases methyl mercury in the industrial wastewater. This toxic contaminated the Minamata Bay and the Shiranui Sea. And because the bay and the sea is contaminated, and the very main source of food of people is the water. People were able to ate contaminated sea foods. This disease is much severe than of the Itai-itai disease. It is not only human who are affected in disease, but also the animals. One of the most affected animal is the cat. There even came the dancing cat fever.

Lastly is the Yokkaichi Asthma. This is due to the burning of petroleum and crude oil. This lead to the huge release amount of the sulfur oxide. And because of this, there came severe smog which causes different diseases, some of these are the chronic obstructive pulmonary disease, chronic bronchitis, pulmonary emphysema and bronchial asthma. People were not able to sleep at night because of their asthma.

Because of these, Japan decided to focus on their laws regarding economy and environment. People wants a change, they rallied and asked the Government to stop this economic growth. They rather choose to pay high amount to their needs than to have this rapid economic growth. They wants to have economic growth but with consideration to the environment and to the people.

After several years, they have proven that these companies were the main reason of the environmental problem. Because of this, the companies were subjected to pay the damages they have done to the people. Trillions and Billions of money were release because the damage is too big. After these, Japan made solutions were they can have economic growth while protecting the environment. And as of now, I could say that Japan is one of the cleanest country. For I have proven it with myself.




We can see here that they have still maintained the beauty of nature as they have their economic growth. Here it proves that people are the powerful one, they are the one that who rule their country. And it is good to see that Japan accepted all changes for them to improve their lives. Because in the end, they are still the one who will benefit in these changes. Now, Japan is continue to grow and Japan is continue to care for their nature. Everyone follows the rules and regulations, and anyone who had disobeyed their laws will be punish in the right manner and in the right time. I hope that in our very own country, the Philippines, we will be able to have this economic growth and people will have to accept all changes that will benefit both. Changes are made to improve not to destroy, so if we want improvement we must accept all changes that will happen. Let us not look for our own benefit but the benefit of everyone. And if we really want to improve, let us start the change in ourselves.

Shell Eco-Marathon Asia 2014 DBTC

Shell Eco-Marathon aims to promote fuel's efficiency. They help the students be aware of the current environmental issues we are facing. It encourages students to build a car which can reach far places with less fuel consumption. Shell decided to have the event proper here in the Philippines due to the 100th year celebration of Shell Philippines.

For this year competition, our school Don Bosco Technical College decuded to make two different vehicle. First, the Hybrid Electric Vehicle or the HEV. And the other one is the Battery Electric Vehicle or BEV. These two cars has its environmental friendly purposes other than of being fuel efficient vehicles. In the Battery Electric Vehicle, one of the part of it is made up of water hyacinth. This plant is very abundant in our country. As the name implies, it grows in the water which could cause flood because of canal blocking. The students decided to use the made fabric matte out of water hyacinth. With this, it could help reduce the water waste. On the other hand, the Hybrid Prototype Vehicle is a retractable car. This vehicle aims to lessen the space being consumed. We all know that there are lots of vehicles in the world and every day manufacturers continue to make cars. And if vehicles will be retractable then it would consume lesser space not only in the road but also in their parking areas.

I am a cadet for the Hybrid Electric Vehicle, yet I also helped the Battery Electric Vehicle. I together with my co-cadets focused in the making of the vehicle's shell. And here is the step-by-step procedure we made.

Pattern Making:
-At first we printed out the design where the scale is 1:1.
-We connect the papers like a jigsaw puzzle.
-We put it in the plywood and cut it with a jigsaw cutter.
-We make it stand and fill the lacks with the paper we used.
-We made use of the used Styrofoams to form the pattern.
-Make the surface flat with the use of sandpaper.
-With the use of Glasurit Patty with Hardener, we get the pattern and make it smooth.
-Apply Blue gel coating.
-Put the fiber matte (Grade 450)
-Apply again Blue gel coating.
-Let it cure for a day and add Glasurit Patty with Hardener and make it smooth.
-Add Acrylic Patty and Primer.
-Lastly, make the surface smooth with sandpaper.

Molder Making:
-Cut strips of illustration board. Approximately 1-1.5 in.
-Put the strips in the middle, make it stand with masking tape.
-Put more strips in the flooring. This will help the mold to be remove easily.
-Apply releasing wax 10-15 times.
-Apply Blue gel coating once.
-Put the fiber matte (Grade 600)
-Apply Clear coating.
-With the use of aluminum roller make the fiber matte flat to the surface of the pattern.
-Apply more fiber matte in the corners and curves and add more clear coating.
-Make sure all matte are flat to the surface of the pattern.
-Let it cure for a day.
-Remove the illustration board in the middle.
-Put some modeling clay or simply put masking tape in the middle.
-Repeat the steps from applying wax up to curing.
-Cut pipes into two and make it pointed.
-Drill the middle, where the two mold will connect.
-With the use of a Rubber mallet and the pipes, carefully remove the mold to the pattern.
-With bold and nut connect the two pieces of mold.
-Add masking tape in the middle.
-Put masking tape in the bottom and cut it with a grinder.

Vehicle's Shell with lamination
-Apply clear releasing wax.
-Add more releasing wax 15 times.
-Apply again clear releasing wax.
-Apply clear coating twice. Make sure to apply it very thin.
-Let it cure for a day.
-Carefully place the carbon fiber.
-Add clear coating and make it flat with aluminum roller.
-To make it stiff put Black gel coating.
-Put the fiber matter (Grade 300)
-Put clear coating once and make sure to make it flat with aluminum roller.
-Let it cure for a day.
-Remove it from the mold.
-Make the surface smooth and cut the hallow part of the shell.

Vehicle's Shell through lamination
-Apply clear releasing wax.
-Add more releasing wax 15 times.
-Apply again clear releasing wax.
-Apply Black gel coating.
-Put the fiber matter (Grade 300)
-Put clear coating once and make sure to make it flat with aluminum roller.
-Let it cure for a day.
-Remove it from the mold.
-Make it smooth with sandpaper.
-Clean it with Lacquer Thinner.
-Apply clear coating twice. Make sure to apply it very thin.
-Let it cure for a day.
-Carefully place the carbon fiber.
-Add clear coating and make it flat with aluminum roller.
-Apply clear coating around 10-15 times.
-Make the surface smooth and cut the hallow part of the shell.

Vehicle's Shell finishing
-Make it very smooth with sand paper from grade 120-2000.
-Clean it with dish washing liquid and make it dry.
-Add rubbing compound.
-Add clear releasing wax.
-Add turtle wax.
-Rub the whole surface with a clean cloth until it shines.

The shell making took us around 2 months in making. In the process, we are asked to wear face mask, long sleeves, pants, and shoes. This is for safety reasons. The components of the chemicals we are using are the following.

Blue Gel Coat
-1 liter Polymer 31-006
-1/4 liter Polystyrene-Monomer
-3 tablespoon Blue Toner
-hardener (when applying)

Clear Gel Coat (Mold)
-1 liter Polymer 31-006
-1/4 liter Polystyrene-Monomer
-4 tablespoon Cobalt
-hardener (when applying)

Black Gel Coat
-1 liter Polymer 31-006
-1/4 liter Polystyrene-Monomer
-3 tablespoon Black Toner
-hardener (when applying)

Clear Gel Coat (Shell)
-1 liter Polymer 31-200
-1/4 liter Polystyrene-Monomer
-4 tablespoon Cobalt
-hardener (when applying)

Base from our professor, these chemical are extremely dangerous to our health. That is why, we are required to drink about a liter of water after a work. We were also advised to intake vitamin C to prevent sick. We were also advise to wear gloves because cobalt mixed with hardener is extremely dangerous. It is flammable and could burn the skin.

These are the steps we took in making our vehicles' shell. We had protective gears in the making and now, we are living safely. And we are looking forward for a better making in the better place for the Shell Eco-Marathon Asia 2015.

A way to Zero Waste..

Last December 18, 2013, we had our Zero Waste Christmas Party in Don Bosco Technical College. This celebration targets to have a party where we enjoy as we prevent to harm our mother nature. As of now, we are facing different environmental problems and the key to solve these problems is in our own hands. As a student we can help to be part in solving this and in a celebration we can contribute in solving by targeting a total zero waste party.

I stand as the organizer of this party. We had invited all the Mechanical Engineering Students to become part of this celebration. We invited them not only to have fun but to make them aware of the current situation of our environment.

On that day, since our batch stand as the very organizer of everything. We divided our class and assigned the foods to be brought. We chose pot lock because having foods prepared by us, has the assurance that it has produced with less waste and contains less preservatives or maybe, nothing at all. Our foods for that day were roasted chicken, pancit, rice and lumpiang togue. For our drinks, we have water and buko juice. And lastly, for dessert, homemade gelatin and mais con yelo. We had fun and very satisfied considering our food are healthy and delicious.

After the simple eating celebration. Since everyone were satisfied, we had decided to have our game after some rest. Our games were egg relay, longest line and agawan base. In here, we promote the importance of perspiration. After being satisfied and full, we need to make ourselves fit and healthy.

We know we cannot easily achieve a zero waste Christmas party. That is why we consider this as a way to Zero waste. For us to achieve this, I have brought the plates, spoons, forks, serving spoons, and the juice container. We have coordinated with the school's cafeteria for some more plates. Our cups were made of paper. We bought this because it is an environmental friendly cups. Left over foods were gathered together in a container. All Calamansi seeds were collected. We decided to plant it and make use of the left over foods as a fertilizer. Waste were segregated accordingly and were placed to the garbage can properly. After that event we had cleaned the whole area including the corridor in our place. Currently, our Calamansi seed is now a plant, continue growing and producing seeds. I take care of our Mechanical Engineering plant and hoping to keep it until the end.

Therefore, we have seen that we had fun and help in solving the environmental problems we are facing. We have waste yet it is sure that these waste were properly segregated. It is less than of the usual waste being produced in a celebration. I am sure that we will be able to fully solve our environmental problems if we will be celebrating like what we had. We must all be aware about these problems and probable solutions we can do. And someday, we will be living peacefully and green fully.
