Masters Degree COMPLETED!


Finally, Master in Biomedical Engineering by one of the world’s most reputed universities in Health Science – Yonsei University – South Korea.

It was a huge challenge, to deal with the distance of the family, with the daily workload from 9am to 11pm in the laboratory, a lot of research, study, weekends, evenings and holidays, always under a lot of pressure, Intelligent and in the subjects of the masters, many presentations and much homesickness.

Breaking the boundaries every day became mandatory, resilience and emotional control were put to the test.

A growth of immeasurable value, experience and acquired baggage that will accompany me throughout my life.

I will be eternally grateful to my family and friends, especially my wife who has always battled alongside me, overcoming limits with me always giving my support, my parents and my sister for the immense support they have always given me and with much love. I am very grateful to FAPETI / UNITAU for this great opportunity and for all the support that I have been given to participate in this project.

This is not my conquest, it is our conquest, and I hope to share it with many people and be able to help them in their achievements and to re-enter the world with this great opportunity.


My Last Semester at Yonsei University

This semester will be my last one on the Master Course in Biomedical Engineering and also my last semester in South Korea. After finish, I will go back to Brazil.


This image represent my performance in the Master Course at Yonsei University and my hard work as well. It was not a simple task to reach this point. I have completed 33 credits and now I have to take just a Map Study Class, which will help me with my master thesis about Brazil’s Regulatory Systems for Medical Devices issued by ANVISA (National Health Surveillance Agency) supported by INMETRO and ANATEL.

I am very glad I took this until the end, and for the fact that I have been prepared to help my country in the Smart Medical Ship project and many other that will come.

It is not all finished yet, so I will preserve the thanks part for the end.

Thanks for following me here.  🙂

See you in the next post.

Medical Devices Training

Hello everyone.

Two weeks ago I posted that I visited 2 companies in Seoul, InBody and i-Sens and now  visited one more, Mediana in Wonju.

They will provide some medical devices which will equip the Smart Medical Ship  in which I work here in South Korea at Yonsei University in a partnership with Brazil’s Universities UNITAU – Universidade de Taubaté and State University of Amazonas and other institutions you can check bellow.


Check post:

The visit was recorded, and now, you can check the videos here and get detailed  knowledge about these devices.

For those who are Portuguese speakers, there are Portuguese subtitles in the video. It required a hard work, but it is very important to make this information accessible to Brazilians.

The first video is a full version about InBody and i-Sens, without any jump cut, therefore, is quite long video and this one specifically do not have subtitles.


The following videos videos are edited with the most important information about the devices and have Portuguese subtitles.

CareSens II – i-Sens Glucose Meter

i-Smart Pro 30 Electrolyte Analyzer – i-Sens


Mediana E40 – Electrocardiograph


Mediana M20 – Patient Monitor


Thanks for reading and watch.

Visit to i-sens and InBody – Seoul, South Korea.

Yesterday, I visited two Medical Devices Korean companies in Seoul, South Korea, i-sens and InBody. Both of them will provide some equipments that will operate in the Smart Medical Ship in Amazônia, Brazil. It was an amazing day of training, getting knowledge about how the devices work. We tested and learn about the i-Smart 30 Pro Electrolyte Analyzer, CareSens II Glucose Meter, and InBody products like the Body Composition Analyzer, Blood Pressure Monitor and Standiometer for automatic Height Measurement. These companies work with high technology which will improve the way people are diagnosed and treated.

My experience doing a Master Degree in Biomedical Engineering in South Korea: Part 01

Hello Everyone. Today I would like to share a part of my experience as a Master Course student in Biomedical Engineering. How it happened? What is like to do a Master Degree program abroad? What is like to be far away from family, friends and face many hours of work and studies?

Well, I have to say that I´m quite sure that is difficult enough. Before I start, I need to give the context.

In 2015 I graduated in Aeronautical Engineering and worked in an undergraduate research about Radar Absorbing Structures (RAS) using carbon and glass fiber and thin films with metal deposition by plasma assisted process in vacuum chamber. I did this for two and a half year until I graduate.

At the same time I was Teacher of a technician course of Computer Graphics (during 4 years) and for 1 year after graduation worked as University Professor of design.

Because of my work in the Materials Laboratory with RAS at UNITAU I was invited to be part of a project of a Smart Medical Ship (SMS) that is being developed by Yonsei University (Wonju – South Korea) and Taubaté University (Taubaté – SP – BR). This SMS will operate in the city of Manacapuru – AM – Brazil and it will be used to improve the health care of the riverside population, what is already an amazing motivation to enter the program and do something good for my country.

So then, I started to prepare myself, all the documents, prepare for the TOEFL Test, which is necessary to enter Yonsei University Master Course program, rent my house in Brazil, I just got engaged with my wife and I had to leave without her and my family, and it was a very difficult part, so I had to be emotionally prepared.

So, what is like to study abroad in a completely different culture at the opposite side of the planet and entering in a new area?

I came to Korea on March 15th of 2017 to start this journey, and the first step was the Korean Language Course.

It was a really complex language course because after came here I never saw even the Korean alphabet in my whole life, so it was whole different new world for me. I did 4 month of course, from Monday to Friday, during five hours a day, and the course really flies, the rhythm is very fast. I had many tests and exams and I had do adapt to this new life. The course time was from 9 am to 1h50 pm and after this I usually had lunch and go to Bio Signal Process Laboratory where I work at the Medical Industry Techno Tower, inside Yonsei University.

The default workload of the Lab is from 9h30 am to 11pm from Monday to Friday and 9h30 am to 6 pm on Saturdays, so it is hard work but I will talk about this later.

The Korean course was pretty difficult since I did not had any contact with this language before, but with many studies, today it is possible for me to handle a basic Korean.

I used to take many notes on my handbook to get trained to write in Korean, and I did many writing exercises on a homework book, which was crucial to develop my Korean skills.

Take a look at some pictures of my studies:

The main purpose of this course for me was to get more involved in the language and Korean culture to be easier to adapt to the new life. Most of the students of my classes was Chinese and most people here in Korea does not speak English which make it even more challenging.

To prevent this post to be too long and boring to read, I will divide in sections and continue in another post. Thanks for visiting my website and see you in the next post.

Medical Image Processing

Hello everyone. Today I want to share a little project of Medical Image Processing (MIP). This project was proposed by the MIP professor here at Yonsei University as a homework on my Master course class, and I decided to do it using a GUI in MatLab instead do only the code and generate figures, I think is more organized to use the GUI. I am able to share the code, if you want this project to study, send me a message by the contact form in this website, it will be a pleasure to send the files.

The task is:

Image manipulation 

  1. Choose any kind of image and set the image size as 256*256.
  2. Divide the above image into 8 pixel x 8 pixel blocks, calculate the average of each block and make a 32 x 32 image using the average.
  3. Reduce the contrast of the image to ½.
  4. Change R,G,B components of the image to 255-R , 255-G, 255-B.
  5. Change the color components to RB, GR, B
  6. Change the color image to a gray image.
  7. Change right and left of the image like a mirror.
  8. Rotate the image 15 degree.

Medical Device Box Patent

First Korean Patent application due to a Medical Device Box Project that will be used by the crew of the Smart Medical Ship in Manacapuru – Amazônia – Brazil, helping to improve the outside attendance to the riverside population. Developed with the Bio signal Processing Laboratory team at Yonsei University – South Korea. The Korean government investment in this project will help to save many lives and improve Brazilian people healthcare. This is a model that can be replicated to other remote areas which does not have good healthcare assistance. I am very proud to be part of this project. A partnership between UNITAU (Taubaté University – BR) and Yonsei University (KR). #medicaldevices #universities #research #healthcare #Brazil #biomedicalengineering
