Chonsangryolchabunyajido is an astronomical chart made in the late fourteenth century.
It dates back to 1395, based on the Koguryo’s astronomical chart carved on a stone.
The Koguryo’s astronomical chart (a table of constellations carved on a stone of about 2 meters in length and 1.2 meters in width) made between the late fifth century and the early sixth century shows 1 467 stars that were visible in the night sky of Pyongyang at that time. They are categorized in 282 constellations in a circle. The black ink copy of them on a piece of paper was used as base data for astronomical observation and calendar compilation.
Chonsangryolchabunyajido (122.8cm wide and 209.9cm long) was considered a very scientific and accurate astronomical chart in those days.
As one of the precious cultural legacies demonstrating the astronomical development of our country in the middle ages, it provides valuable information for the study of astronomical history.

Kim Chaek University of Technology International Conference―2025 was held on the subject “Science and Technology―Power for Development and Strategic Means” from November 11 to12.
Presented there were 120-odd scientific and technological papers of great scientific value and practical significance.
Drawing some universities and scientific research institutes from several countries including Russia and China, the conference was divided into five sections: Earth and Environmental Science, Metallurgy and Material, Mechanical and Energy Engineering, Automatics and Information Technology, and Basic Science, Chemical Engineering and Bioengineering.
Many academic findings achieved in the scientific research were reported from many papers including “Effective Non-seismic Technologies for Exploring Reservoir of Oil and Gas”, “Effect of Laser Power and Scanning Speed on Properties of Laser-Induced Graphene”, “A Method for Improving Accuracy of Positioning based on RSS Model in 3D Wireless Sensor Networks”, etc.
During the conference, the university hosted a reception for the participants.
The conference served as a good occasion of exchanging valuable experiences and knowledge.

November has two seasonal divisions―riptong and sosol.
Riptong refers to the beginning of winter while sosol indicates the start of snowfall. The former falls on 7th or 8th and the latter falls on 22nd or 23rd of November.
What is important in the Korean people’s dietary practices was to make kimchi and to steam soybeans for making soybean paste of the next spring.
Regarding kimchi as important food supply for winter, the Korean people have long attached great importance to preparing kimchi. The materials and recipes were different in different parts of the country.
At this time every year, people made whole cabbage kimchi and other kinds of kimchi of different tastes and aromas peculiar to different localities including watery radish kimchi, wrapped-up kimchi and leaf-mustard kimchi.
The housewives of several families cooperated to make kimchi in turn and they regarded offering their fresh kimchi to their neighbours first as a moral practice.
Steaming and making balls of soybean for making soybean paste in the next spring was also an old custom handed down from generation to generation.
The folk games of this season include some indoor games like yut-game, paduk, Korean chess, etc. suitable for cold weather conditions and some outdoor games including kite-flying, shuttlecock, etc. enjoyed by children.
