Geological terminology used in Korea which has been politically separated for the last 50 years, were compared. For this study, geological terminology used in 'Geology of Korea' published in North Korea (1996), 'Geology of Korea' published in South Korea (1999) and other geological publications were compared. Among the 1272 geological terminology used in North Korea, 49 are for geochronology, 201 for mineralogy, 199 for petrology, 257 for structural geology, 93 for paleontology, and 473 for general geology. Out of these geological terminology, 657 (51.7%) have the same pronunciation and meaning as those used in South Korea 370 (29.1%) are analogous words, and 245 (19.2%)cannot be understood because of differences in the means of expression. Differences in geological terminology used in the two Koreas are thought to be mainly caused by language used only in North Korea, different foreign language interpretation, different initial law application, new connecting word construction, and influence from different cultures.

The purpose of this study was to analyze the geological terms used in the elementary school science curriculums from 1876 to present. We collected the data of geological terminologies based on what is being used in the revised 2007 national curriculum. In this study, data was divided into three periods according to political events, "The Modern Enlightenment Period (1876~1910)", "The Japanese Colonial Period (1910~1945)", and "The Current Curriculum Period (1945~present)". During the early modern enlightenment period, translated Chinese characters' terminologies by western scholars in Qing-China were used in science books. The late modern enlightenment period, we used many translated Japanese textbooks in schools, which naturally introduced the way that Japan's terminology is used. In the Japanese colonial period, Korean students had to study science subjects written in Japanese characters, so they had used Japanese terminologies of science. After the liberation of Korea from the Imperial Japan, there was an efforts to make new Korean terminologies of geology under the new current national curriculum. However, the terminologies used in Korean textbooks ended up using and borrowing the same way that the Japanese-Sino terms of science used later.

The purpose of this study was to analyze the characteristics of the geology-related contents in the 1st~7th elementary science curriculum. Our analysis was based on the analytical frameworks of geology-related contents (the structure of the contents, the amount of teaming, the contents of the experimental activities, the transitions of the terminology, and the change in the number of illustrations). The results are as follows: 1. Consistently covered contents were limited to weathering of the rock and soil, igneous rock, sedimentary rock, metamorphic rock, and the change of the earth's, fold and fault, earthquake and volcano, geologic stratum and fossil. 2. The geological contents account for (average), 11.5% (maximum), and 5.1% (minimum) of the elementary science curriculum. Most contents covered in the curriculum were rock and soil, and the change of the earth's surface. 3. Continuously covered experimental contents were the weathering and soil, igneous rock, change of the earth's surface, geologic stratum and fossil. 4. The terminology on the rock was the most frequently changed. Whenever the curriculum changed, the addition, deletion, or renaming of terminology led to confusions. 5. In terms of the transition of illustrations, the pictures replaced the figures or diagrams as the representative illustration methods as the science or the textbook compilation skill develope. The cartoons or tables were also used increasingly in order to help the children to understand and pay attention to study.

This study examined whether the "self-guided interpretation" media in the Yeoncheon area of the Hantangang River UNESCO Geopark are intelligible for visitors. Accordingly, two on-site investigations were conducted in the Hantangang River Global Geopark in September and November 2022. The Yeoncheon area, known for its diverse geological features and the era of geological attraction formation, was selected for analysis. We analyzed the readability levels, graphic characteristics, and alignment with science curriculum of the interpretive media specific to geological sites among a total of 36 self-guided interpretive media in the Yeoncheon area. Results indicated that information boards, primarily offering guidance on geological attractions, were the most prevalent type of interpretive media in the Yeoncheon area. The quantity of text in explanatory media surpassed that of a 12^th-grade science textbook. The average vocabulary grade was similar to that of 11^th- and 12^th-grade science textbooks, with somewhat reduced readability due to a high occurrence of complex sentences. Predominant graphic types included illustrative photographs, aiding comprehension of the geological formation process through multi-structure graphics. Regarding scientific terms used in the interpretive media, 86.3% of the terms were within the "Solid Earth" section of the 2015 revised curriculum, with the majority being at the 4^th-grade level. The 11^th-grade optional curriculum terms comprised the second largest portion, and 13.7% of all science terms were from outside the curriculum. Notably, variations in the scientific terminology's complexity was based on geological attractions. Specifically, the terminology level on the homepage tended to be generally higher than that on information boards. Through these findings, specific factors impeding visitor comprehension of geological attractions in the Yeoncheon area, based on the interpretation medium, were identified. We suggest further research to effect improvements in self-guided interpretation media, fostering geological resource education for general visitors and anticipating advancements in geology education.

The increament of crustal thickness, continental growth and evolution, plate tectonic movements, and mega-impacts of meteorites have been worldwidely studied in the subdivision of Precambrian. In many subdivision methods of Precambrian Eon and Eonthem, the division based on the principle of the Plate tctonic movement referred internationally, is as follows, $L^AT_EX$ The rationality of this subdivision and some problems in the currently adopted stratigraphic subdivision of Precambrian Eonthem will by commented, and the validity of English and Korean Geological terminology on the Precambrian stratigraphy of northeastern Asia will be discussed also.

Jeju island has a special ground layer called 'Sumgol' due to the geological characteristics. The terminology 'Sumgol' is generally defined as the rain fall flows through the Sumgol without blocking and smaller size than cave, which men cannot enter. This paper presents the influence of the Sumgol on ground stability under various loading conditions using numerical simulations when the airport is constructed. The results showed that the vertical settlements of each section are within the allowable settlement.

Upon the human exploration era of the Moon, this paper introduces lunar topography and geologic fundamentals to space scientists. The origin of scientific terminology for the lunar topography was briefly summarized, and the extension of the current Korean terminology is suggested. Specifically, we suggest the most representative lunar topography that are useful to laymen as 1 ocean (Oceanus Procellarum), 10 maria (Mare Imbrium, Mare Serenitatis, Mare Tranuillitatis, Mare Nectaris, Mare Fecundatis, Mare Crisium, Mare Vaporium, Mare Cognitum, Mare Humorum, Mare Nubium), 6 great craters (Tyco, Copernicus, Kepler, Aristachus, Stebinus, Langrenus). We also suggest Korean terms for highland, maria, mountains, crater, rille, rima, graben, dome, lava tube, wrinkle ridge, trench, rupes, and regolith. In addition, we introduce the standard model for the lunar interior and typical rocks. According to the standard model on the basis of historical impact events, the lunar geological eras are classified as Pre-Nectarian, Nectarian, Imbrian, Erathostenesian, and Copernican in chronologic order. Finally, we summarize the latest discovery records on the water on the Moon, and introduce the concept of water extraction from the lunar soil, which is to be developed by the Korea Institute of Geoscience and Mineral Resources (KIGAM).
