Goal

Add explicit References / 참고문헌 entries to the new chapters being created under the #402 restructure plan, plus existing notebooks that lack them. nmisp already cites international authors in mechanics/linux chapters (Pytel et al., William Shotts) — extend the same pattern to the Python-content chapters.

Two distinct sources, different scopes

These are different categories of source and should be cited at different "weights." Don't conflate them.

1. Nakakuki Kenji — Python for Engineers (book) — broad scope

• Korean edition (the one read by the course author): 나카쿠키 켄지, 심효섭 역, 엔지니어를 위한 파이썬, 제이펍, 2017. ISBN 979-11-88621-02-6. (source repo)
• Original Japanese: 中久喜 健司, 科学技術計算のためのPython入門 ――開発基礎、必須ライブラリ、高速化, 技術評論社, 2016. ISBN 978-4-7741-8388-2. (source repo)

Role: architectural reference for the Python toolbox content (numpy, scipy, matplotlib, pandas) covered across 03_python_basics/ and 06_python_advanced/. This is a textbook-weight citation, comparable to Pytel et al. for the mechanics chapters.

2. utokyo-ipp.github.io — narrow scope

• University of Tokyo, Pythonプログラミング入門, https://utokyo-ipp.github.io/ (CC BY-NC-ND 4.0).

Role: structural influence on the testing/debugging chapter (#392) only. Not a textbook-weight citation; just a "this idea was shaped partly by this public curriculum" link in the chapter's Further reading cell. Do not list in the README — that would over-weight a single-chapter influence.

Where to add

• README — add a ## References / 참고문헌 section listing the Nakakuki book alongside existing references (Pytel et al., Shotts). utokyo-ipp does not belong here.
• 06_python_advanced/10_testing_debugging.ipynb (Pedagogy: add testing & debugging notebook under 06_python_advanced/ #392 ) — ## Further reading cell at the end with the utokyo-ipp link, framed as a structural influence on the chapter.
• First notebook of 03_python_basics/ (per Pedagogy: split 20_python_review into focused notebooks under 03_python_basics/ #391 ) — Reference cell citing Nakakuki as the Python-content architectural source.
• First notebook of 06_python_advanced/ — same Nakakuki citation.

Format

Match the bilingual pattern already used in 30_num_int/30_T_section_centroid.ipynb and 60_linear_algebra_2/110_Beam_Reaction_Force.ipynb:

참고문헌 : 저자, 제목, 출판사, 연도.<br>Ref: Author, Title, Publisher, Year.

For Nakakuki, cite the Korean translation primarily (the read edition) with the Japanese original in parentheses or on a second line.

Why

• Fair credit signals scholarship and is a virtue of open-source educational material.
• The Meta: 00_introduction restructure — motivation chapter + 03_python_basics + 06_python_advanced #402 restructure reshapes the Python content significantly; tracking which references shaped which chapter helps future contributors and translators stay aligned.
• Distinguishing scope (textbook vs. one-chapter influence) keeps the citations honest.

Acceptance

• README has a ## References / 참고문헌 section listing Nakakuki + existing references.
• Pedagogy: add testing & debugging notebook under 06_python_advanced/ #392 notebook ends with a Further reading cell that includes the utokyo-ipp link.
• First notebooks of 03_python_basics/ and 06_python_advanced/ each cite Nakakuki.
• All new citations are bilingual (Korean + romanized/English where appropriate).
• utokyo-ipp does not appear in the README.

Dependency

• Notebook-level citations need their host notebooks to exist first (per Pedagogy: split 20_python_review into focused notebooks under 03_python_basics/ #391 , Pedagogy: add testing & debugging notebook under 06_python_advanced/ #392 , etc.). README citation can land independently any time.
