There's a reason why scabs form!

There is a reason why everything happens.
When you get a wound, bleeding and scabs don't just happen.
It's just that things happen in places we can't see, so we don't really know why or how things happen.
Wounds don't magically heal overnight.
It is the result of each and every cell in our body doing its part.
"At That Time, In The Wounds" is a book that shows what happens inside and outside the body until the wounds heal and new skin grows.
By showing the process of wound healing through the external aspects that we are familiar with and the internal aspects that we are not familiar with, we help children understand life activities in an organic and integrated way.
By learning more about the invisible world through this book, you will come to understand your body more deeply and love and cherish it more.


How can the wounds on my body heal?
The internal and external wound healing process of our body

During gym class, the main character, 'I', falls while playing soccer and gets a wound on his knee.
When a wound occurs, the skin tears and bleeds.
At the same time, bacteria that were outside begin to enter the body through the wound.
To prevent blood from leaking out, blood vessels constrict and platelets gather at the wound site.
A bandage is placed over the wound of 'me' who received first aid at the infirmary.
Inside the bandage, platelets and proteins clump together to form a scab, and white blood cells eat bacteria that have entered the body.
As cell division begins beneath the scab and new skin begins to sprout, everything inside and outside of my body falls into place.

This book cross-references what happens inside and outside our bodies when we are injured, revealing the inner workings of our bodies that we never knew existed.
It teaches us about the physiology of our body by providing answers to questions such as, 'Why do wounds bleed?', 'Why does bleeding stop after a while?', 'Why do scabs form?', and 'Why do wounds sting?'
We've all had the experience of scratching a wound because we couldn't stand the itchiness, and the scab fell off and started bleeding.
This book clearly shows why you should never scratch a scab, no matter how itchy it is, and guides you to manage your wounds properly.


There is someone or something working hard behind the scenes!
A book that raises interest in the invisible world

Author Kim Seong-eun, who has consistently written articles that convey knowledge in an easy and fun way at a level suitable for children, began writing this book out of curiosity about a world that clearly exists but cannot be seen.
This book, which explores the hidden side of phenomena that occur around us every day but are rarely looked into, tells the story of small but great lives that do their part in unseen places.
Not only does it vividly show us the healing process that occurs within our bodies through situations of injury, it also helps us develop the ability to view our bodies in a more organic and integrated way.


What makes this book shine even more are the illustrations by author Lee Su-hyeon.
The illustrations, which depict blood components such as 'red blood cells, white blood cells, and platelets' as cute and attractive characters that bring out their characteristics, make us feel much more familiar with the components of our body that are often perceived as unfamiliar and difficult.
Additionally, it vividly portrays each scene based on accurate information, allowing us to accurately understand the phenomena occurring inside and outside our bodies and immerse ourselves in the story.
Like scenes where blood vessels constrict to prevent blood from leaking out, and platelets and proteins clump together to seal a wound.


The accuracy of the information was enhanced through multiple revisions by Dr. Namgung In, an emergency medicine specialist.
I hope that through this book, young readers will gain a true understanding of what happens in places we cannot see, and furthermore, become interested in the invisible world that is still working diligently today.
