@leonard773737,
Thank you for your patience.
You can use the FontsManager class to embed any TTF font into your PowerPoint presentation like this:
with open("MyFont.ttf", "rb") as font_data:
presentation.fonts_manager.add_embedded_font(
font_data.read(), slides.export.EmbedFontCharacters.ALL)
In this case, the font will be displayed correctly in PowerPoint, its presence in the operating system is not required.

It works.
but pptx file changed “readonly”.
how can I change file for “write” attribute?
Thanks for help 
@leonard773737,
If your presentation has been marked as “Read-Only”, you can remove this protection as follows:
file_name = "MyPresentation.pptx"
with slides.Presentation(file_name) as presentation:
presentation.protection_manager.read_only_recommended = False
presentation.save(file_name, slides.export.SaveFormat.PPTX)

Thank you for the files. I am working on the question and will get back to you as soon as possible.
@leonard773737,
Fonts have embedding permissions, which are set by the type foundry. In your case, the EBS Hunminjeongeum R font is read-only embedded, so the message appears in PowerPoint. You can use a different font.
