Han Jeoung-ae

Han Jeoung-ae is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Han Jeoung-ae rather than just read about it. In short: Han Jeoung-ae (Korean: 한정애; Hanja: 韓貞愛; born 8 January 1965) is a South Korean politician and a three-term parliamentarian representing Gangseo District of Seoul at the National Assembly from 2016. Han also served as Minister of Environment under President Moon Jae-in from 2021 to 2022.

Key takeaways

Han Jeoung-ae belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Han Jeoung-ae to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Han Jeoung-ae from memory before moving on to harder problems.

Reference excerpt

Han Jeoung-ae (Korean: 한정애; Hanja: 韓貞愛; born 8 January 1965) is a South Korean politician and a three-term parliamentarian representing Gangseo District of Seoul at the National Assembly from 2016. Han also served as Minister of Environment under President Moon Jae-in from 2021 to 2022.

Trade unionist After graduating from Pusan National University, she worked at Korea Occupational Safety and Health Agency. After completing her doctorate studies in the UK, she returned to the Agency. In 2005 she became the head of its trade union. And in 2006 she became the deputy chair of Federation of Korean Trade Unions's public servants bureau. She continued to take leadership roles in the trade unions before entering politics for the 2012 general election. From 2006 to 2011, she has taken multiple roles in formulating labor-related policy, such as a member of sub-committees of then-Economic and Social Development Commission (now-Economic, Social and Labor Council) and the highest governing bodies of National Pension Service and National Health Insurance Service, as a trade union representative.

Parliamentarian In the 2012 general election, she was placed as the number 11 of the party's proportional representation list. In the 2016 general election, she defeated the former Gangseo District mayor from the opposition party. She has taken multiple roles in her party and its preceding parties including one of members its Supreme Council, its deputy floor leader and its spokesperson as well as deputy chair and senior deputy chair of its Policy Planning Committee. In 2018 she received Lush Prize in lobbying category for her legislative work in supporting alternative safety testing to animal testing. In 2020 she was elected as the chair of National Assembly's Health and Welfare Committee responsible for scrutinising Ministry of Health and Welfare, Ministry of Food and Drug Safety and related agencies. In August 2020 newly elected leader of her party, Lee Nak-yeon, appointed her as the chair of party's Policy Planning Committee and she subsequently resigned from the elected chair of the Health and Welfare Committee. In September Lee appointed her and Yang Hyang-ja as the co-deputy chair of party's K-New Deal Committee led by party floor leader Kim Tae-nyeon.

Minister President Moon Jae-in nominated Han as his next Minister of Environment on 30 December 2020. Democratic party leader Lee Nak-yon replaced Han with Hong Ik-pyo to chair the party's policy planning committee.

Education Han holds two degrees - a bachelor in environmental engineering from Pusan National University and a doctorate in industrial engineering from University of Nottingham. She also completed postgraduate programme in environmental engineering at Pusan National University.

Worked examples

Example 1 — a first encounter with Han Jeoung-ae

Start with the simplest possible case. Write down what Han Jeoung-ae claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Han Jeoung-ae before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Han Jeoung-ae ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Han Jeoung-ae

In research: Han Jeoung-ae appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Han Jeoung-ae in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Han Jeoung-ae is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1965 births, 21st-century South Korean politicians, 21st-century South Korean women politicians, so understanding it makes those chapters shorter.
In everyday life: Look for Han Jeoung-ae outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
