Rakwon

Rakwon is a science 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 Rakwon rather than just read about it. In short: Rakwon (Korean: 락원; lit. 'paradise') is a video conferencing software. It can be accessed through Kwangmyong.

Key takeaways

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

Reference excerpt

Rakwon (Korean: 락원; lit. 'paradise') is a video conferencing software. It can be accessed through Kwangmyong. It was developed by the Kim Il Sung University in North Korea. This virtual meeting system houses functions for sending videos and voice files, accessing electronic documents simultaneously, and for performing real-time multi-media tasks and virtual meetings. Due to the restrictions on travel in North Korea, the technology can prove to be instrumental in connecting people in remote areas with institutions located in the capital city. Early photos of Rakwon indicate that it runs on North Korea's Linux operating system, Red Star OS. Newer versions of Rakwon seem to be working on Microsoft Windows.

History Rakwon was first reported by an article from Chosun Sinbo in January 2012, which claimed that the video conferencing software, developed by the Kim Il Sung University, won a gold prize at a technology festival in September 2011. In 2019, Korean Central News Agency reported that the group that developed Rakwon had won the prestigious "February 16 Science and Technology Prize", a top national science and technology award in the DPRK, for that year. The report claimed Rakwon "had been introduced throughout the country". The software wasn't mentioned in news releases until 2020. Throughout the COVID-19 pandemic, Korean Central Television regularly reported and highlighted use of the Rakwon software in workplaces and factories in the country. The meeting on 23 June 2020, when Kim Jong Un led a preliminary meeting of the Central Military Commission via Rakwon, was the first time that an online meeting was managed by Kim as well as the first entirely online meeting. In a news report, a meeting screen showed 37 organizations participants. The list indicated that Rakwon network was widely used by North Korea's industrial enterprises and now links together central and provincial government organizations. In 2021, one of the biggest North Korean annual expos, the National Exhibition of IT Successes (전국정보화성과전람회), took place online through Rakwon. As nobody outside North Korea has access to the software, international video conferences are conducted with foreign video conferencing software.

Worked examples

Example 1 — a first encounter with Rakwon

Start with the simplest possible case. Write down what Rakwon claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Rakwon 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 Rakwon 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 Rakwon

In research: Rakwon appears in science 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 Rakwon 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: Rakwon is common in secondary-school and first-year university syllabi. It links to neighbouring topics Internet in North Korea, Videotelephony, so understanding it makes those chapters shorter.
In everyday life: Look for Rakwon 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.
