Looking Back on 2024 and 2025, and Still Dreaming of a New Start

When my most recent biotech workplace shut down, I found myself at a crossroads. I still had the energy to dream of building a biotech startup, but after watching two companies I worked for shut down, I couldn’t even convince myself it would succeed.

So, instead, I took a different path. I enrolled in a free nursing course, a CNA program near my home, because I wanted to learn how I could continue helping others. That choice took me back in time to 1997–1998, when I worked with my college seniors in the psychology therapy club Torch Band and visited juvenile detention centers and psychiatric hospitals. Later, in 2008, I also learned about sandplay therapy. Those memories resurfaced as I began my new journey in nursing. After receiving my CNA certification, I worked at a nearby memory center while also preparing for pre-nursing courses. Since my previous college studies hadn’t included all the required U.S. nursing prerequisites. For example, I had taken animal physiology but not human physiology, so I needed to fill such gaps. At the memory care where I worked for a while, I noticed that quite a few seniors struggling with memory loss also had glaucoma. I can’t say that’s scientifically proven. I just noticed that some studies failed to show significant statistics on the connection. Someday, if I have the time, I’d love to dig into Korea’s public medical insurance datasets and explore the common mechanisms behind these conditions in more detail. What made me truly happy was seeing positive changes in the seniors with memory problems I cared for.

Maybe my interest in nursing was also influenced by my first daughter. In high school, she joined a medical club, and before college, she even took part in a high school internship program at Scripps Hospital. Later, even after choosing computer science as her major at UC Davis, she pursued EMT training. But in the summer of 2025, both of us stepped away. I quit my role as a care manager, and she stopped EMT training. That early summer, she was struck by a virus and diagnosed with meningitis. For nearly a month, her life was at risk, and I stayed by her side, helping her fight to survive. It brought back memories of my own hospitalization, when I spent a month with a high fever and no diagnosis. I still remember that near-death moment. Even in that split second, the experience remains etched vividly in my mind.

Even now, I still want to learn more about clinical care, but at the age of 50, it feels too late, less enjoyable, and not quite aligned with my current situation. While taking some pre-nursing courses, I also began exploring computer-related courses online and still hope to keep learning new things. My dream of starting a biotech company inspired me to explore publishing ventures, try self-publishing, and eventually start a nonprofit with my younger daughter. She is actually the founder and guiding force behind the BunnyPals Foundation. BunnyPals started as a small club for kids who had bunnies, but now it has grown to include writing and craft clubs, as well as Korean language learning. I hope to help children nurture creativity, compassion, and environmental awareness through artistic expression, storytelling, and community engagement. I also dream of helping them become authors of their own creative works.

Part of me still dreams of returning to research or building a research-focused nonprofit or startup. I wait for that dream. 

Looking back, my life has been a journey of choices. Some I treasure, some I wonder about. For example, I once had the chance to pursue medical school or clinical psychology, but I didn’t. Do I regret it a little? Yes. But deep down, I know that even if I could go back, I might still choose this same path.

As an undergraduate in Korea, I never knew clinicians could also be researchers. I simply wanted to discover something new and contribute to patients’ well-being as a scientist. Also, I know if I chose a different path, I would have never researched. Now, though, I believe that for most people, education and lifestyle changes should come before medication.

To my juniors, including my daughters, I hope you’ll always find the resources you need for your career paths and that you’ll follow not just ambition but also your heart. May you always be wise enough to find balance between life, work, and money.

GoJoseon—The first kingdom in Korea

Records about Gojoseon are found in the book Samguk Yusa (written by Buddhist monk Iryeon), which says that it was founded in 2333 BCE by Dangun Wanggeom.

According to the Dangun myth, Hwanung (a heavenly being who descended to earth) had a son named Dangun with Ungnyeo (a bear who transformed into a woman). The country that Dangun established was called Joseon.
Later in history, another kingdom called Joseon appeared, as you know, so historians use the name Gojoseon (“Old Joseon”) to refer to the earlier kingdom. Chinese historical texts such as the Shan Hai Jing and Guanzi also mention Joseon.

Gojoseon was based on a Bronze Age culture but broadly seems to cover the late Neolithic and early Iron Age and was said to have the Law of Eight Prohibitions. Among them, three laws are still passed down and known:

  1. A person who commits murder shall be executed.
  2. A person who injures another must compensate with grain.
  3. A person who steals shall become a slave. To redeem themselves, they must pay a fine of 500,000 coins.

It is believed that Gojoseon’s territory may have reached as far south as present-day Seoul.

In Korea, many dolmens (ancient stone tombs, Goindol in the Korean pronunciation) can still be found throughout the Korean Peninsula.


If you want to see a representative example, you can visit LegoLand in Chuncheon, South Korea, where such remains as Neolithic pit houses and Goindols scattered. In fact, it is known that the land beneath LegoLand contained many archaeological things, and the construction of the park was heavily opposed. Despite this, LegoLand was eventually built on the site.

 You can check it out on this website! But the information is written in Korean.


There is one Korean drama, Tae Wong Sa Shin Gi based on the Gojoseon legend.

Unfortunately, there are still no officially English-dubbed versions. JustWatch and Netflix only provide non-English versions.

There is some OST series of Tae Wong Sa Shin Gi on YouTube.

and….

I found Ep2 (Eng Sub) of Tae Wong Sa Shin Gi on YouTube

배 | Boat

2021/3/26 김수영 씀

바다에
배한척
배 안엔 혼자

  비가 온다
폭풍이 친다
파도가 널 뛴다

  시간만 많다면
허락이 된다면
배를 지키고 싶다
바다가 잠잠해 질때까지

  배에 사람을 테우고 싶다
사람을 테울만큼 사이즈의 배이고 싶다

  배를 버려야 하는 때인지
지켜야 하는 때인지
알수 없다

  단지 내가 아는건
배 밖
육지엔
날 지키고자하는
내가 지켜야하는
사람들이 있다는것이다.


The Boat

March 26, 2021, written by Sooyoung Kim

Adrift on the sea,

a solitary boat

and I, its only soul.

Rain begins to fall.

The storm roars.

Waves rise and crash like beasts in revolt.

If only time were on my side,

if only I had permission

I would stay,

guarding this boat

until the waters quiet,

until the storm forgives.

I dream of filling this vessel with others,

of becoming a boat

wide and strong enough to carry them.

But I do not know

whether this is the time to let go

or the time to hold on.

All I know is this:

beyond the bow,

on distant land,

there are those

who would shield me

and whom I must protect

in return.

존재 | Existence

길을 걷는다
문득 발  아래 개미를 인식한다
 
내가
존재하고
내가
일 하는 방식이
나도 모르는 사이
죽어나가는 개미를
만들어 낸다면
 
나도 열심히
거인들의 발아래에서
죽지 않기 위해
피해다니는 형국이라면
 
때론
이것이 사는 것이라면
 
내 발아래 개미를 깨닫는 순간도
내 위 거인의 발바닥을 느끼는 순간도
그닥 유쾌한 경험은 아니다
Walking down the street
Suddenly I realize the ants under my feet

If my existence and the way I work
creates ants that die without me knowing

If I also work hard
to avoid dying under the feet of giants

If sometimes this is living

The moment I realize the ants under my feet and also
the moment I feel the soles of the giants' feet above me
are not very pleasant experiences

Cabbage looper | Owlet Moths | Trichoplusia ni

May 22, 2025 by Sooyoung

Today, I searched for Trichoplusia ni (cabbage looper) and the reason why it is used for protein expression.

The cabbage looper is a medium-sized moth commonly called owlet moth, and it is known for its distinctive looping movement as a caterpillar. So, the caterpillar is commonly called a cabbage looper, and the adult cabbage loopers are called owlet moths.

A picture of owlet moth from webpage, russellipm.com

You may visit YouTube to see Looper. 🐛

Why it is used for protein expression and how the technology has been developed:

Trichoplusia ni (cabbage looper) is used for protein expression due to its ability to produce recombinant proteins at high levels and with good quality, particularly for SECRETED proteins. Its insect cell lines, such as Tni-FNL, have demonstrated superior protein production compared to other winged insect (lepidopteran) cell lines of Spodoptera frugiperda (fall armyworm moth). Furthermore, some Trichoplusia ni cell lines (Tni-FNL) have shown improved growth rates and the ability to grow at lower temperatures. 

Who developed:

The High Five (BTI-Tn-5B1-4) cell line, derived from the cabbage looper (Trichoplusia ni) eggs, was first developed by the Boyce Thompson Institute for Plant Research in 1970. Another Trichoplusia ni cell line, Tni-FNL, was developed by researchers at the National Cancer Institute in 2018.

What we think about protein expression:

Protein yield, Scale-up, Toxicity, Post-translational modification, growth characteristics, how could be advanced further…..

What is life?

by Moon family May 11, 2025

On the way home from school, Grace and I discussed what life is. First, Grace said, life needs WATER. Dried things have no life in there, and we discussed eating, pooping and peeing – METABOLISM. Life needs metabolism for ENERGY. 

The discussion has been continued, and today during the mother’s day dinner time, we added TEMPERATURE. Corpses have no body temperature she said. Finally, her dad, my hus added SPIRIT, and then,

What else? Grace tried to add OXYGEN, but we did not agree on it, because humans need OXYGEN, but not for all living things.  

On this question of “What is life”, I felt that it is very interesting. We could think of the simple question in the view of everything from tiny unicells such as bacteria to the bigger organisms like humans and even the universe. I thought about himan vital signs such as breathing and blood pressure as well.

Suddenly, i murmured the unscientific idea that all things have life because they have birth and extinction. 

We might continue thinking of what life is.
