End of Year Reflection

This year has been a long year. I joined a student organization called the Korean Student Association as treasurer, got into my major BME, and already done with half of my university life. In academics it has been rough and good. My autumn semester has been a little bit rough and it was hard to get good grades. My spring semester has been a motivating time for me in my studies. I feel like I studied a lot harder this semester compared to the semesters before and I am satisfied with my performance! I hope semesters to come would be as good as it was this semester.

Vision Statement

My vision for the remaining time on campus is to maintain and get a higher GPA. As much as everything else is important, I also feel GPA is a big part in getting a job in the future. I will be starting undergraduate research over the summer so I would like to learn a lot more deep into my major. Next summer I would like to get an internship opportunity. For now, focusing on academics while keeping up with my participation in student organization is the focus.

BME Project

For my BME 2700 Numerical Simulations class, I had to do a project with my partner Andy Denney as a FEM (Fundamental Engineering Modeling) project. We observed the structural deformation of biomedical stents. The original stent model was downloaded from the COMSOL application gallery in a file called the Shape Memory Alloy Self-Expanding Stent. The geometry of one of the work planes was altered to modify the stent in different forms of degradation. A Bezier polygon that connected points was used for the dent model and an ellipse was used for the hole model. Applications of union, split, and delete entities were used for both models to finalize the modification. Figure 1 below shows the original stent designs and the changes made to each design from a work plane perspective. Some key assumptions during the study were keeping the material of austenite constant throughout each model and that each functional unit of the stent would have the same mode of degradation for the whole stent. The material was kept constant since we aimed to observed the effect of degradation on a stent. Different materials could affect stress distributions in different ways, so a constant material is crucial to observe stress changes purely from degradation. The original model had the functional unit of the stent extruded and revolved to form the whole stent. Because of that, a modification made to one functional unit of the stent would impact every other unit of the stent.

Abstract

Hello, I am Andrew Choi and I am a biomedical engineering major. I just finished my second year in college. My e-portfolio will include some of my everyday life in OSU, and also academic things like projects I do, and also posts about undergraduate research I will be starting during the summer. Hope you enjoy looking through my e-portfolio!

End of semester reflection

Throughout this semester, I especially developed my time management. During high school, I mostly waited until the last minute to do all of my homework, and didn’t even think about doing any schoolwork until after I eat dinner. Even though I may be in a classroom less time than during high school, I realized I needed to put in more effort to school work than I used to. I started to use my time more efficiently. Instead of waiting until after dinner, I used the time in between classes to study and do homework. After coming to college, I feel like I am actually learning things instead of just mostly memorizing like I did during high school. Some of my significant improvements are: previewing class material, using time efficiently, and having a goal of finishing homework 1 or 2 days before the due date.

GOALS of Honors and Scholars

The GOALS of the honors and scholars program include global awareness, original inquiry, academic enrichment, leadership development, and service engagement. Global awareness is developing awareness of diversity. Ohio State is one of the most diverse campuses with students from all over the world. By being Korean, I already contribute to the diverse community, and I am open to everyone to share my culture and learn the other person’s unique culture. Original inquiry focuses on research or projects that leads students to become creative. I plan to try to get involved in a research lab after my sophomore year. Academic enrichment is going towards academic excellence. With my goal of becoming a dentist, I am planning out my classes for the next four years of undergraduate years, and also focusing on my current academics by reviewing and studying the class content every day after classes. Leadership development is for students be become a leader in all kinds of aspects. Currently, I am not sure about how I could become a leader but I will try to find opportunities that I can thrive as a leader. However, one example of me being a leader is through my engineering class. By motivating the other students in my group, I am able to lead the group to all equally work on projects for the class. Service engagement is serving the community. I will try to not just serve for the required 10 hours, but more for the community.

Scholars Event Experience

On September 1st, the Ohio State University men’s soccer team faced Lehigh University’s men’s soccer team at Jesse Owens Stadium. As a scholars community, we went to watch the game. Even though I knew the OSU had many different sports teams, the only team that I really knew about was the football team. It was an interesting experience to watch and especially since the Buckeyes won the game! From this experience, I gained insight into other sporting events that happen in OSU.

About me

Hello I am Andrew Choi. I am in the biological sciences scholars program and major in biomedical engineering. Some experiences that shaped me is the different places where I lived in the past. I lived in South Korea for about 8 years and then moved back to the US during my freshman year of high school. The different cultures I experienced helped me to understand the diversity of many different people. I thought the Ohio State University will be a good place more me to experience even more diverse cultures by meeting new people from all around the world.

I chose the scholars program because of the community. I liked how the people around me in the program are students who are eager to learn. Also, since some of my peers have similar interests of pre-dental, I thought it would be a good way to share information and go towards the dental track. Also, the mentor opportunities and the connections to faculty members, alumni, etc by the scholars program attracted me to join it.

I am a freshman at Ohio State majoring in biomedical engineering. I would like to go towards the pre-dental course to become a dentist.
