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 is to compare by learner groups(K-12, geology-related majoring students, science teachers) how geologic fieldwork education cases in domestic and foreign papers for recent 20 years reflect the elements of inquiry in field geology. The total number of analyzed cases is 53(58 for double counting), and the analysis was conducted on the elements of inquiry in field geology and their sub-element. As a result, there was a clear difference between the cases of geologic fieldwork education for K-12 and college students majoring in geology-related disciplines, in the way of reflecting elements of inquiry in field geology. Because most of K-12 target fieldworks were designed based on the curriculum, it mainly included 2-3 elements of observations, representations, and/or abductive reasoning. On the other hand, because fieldworks for geology-related major students aim to train geologic experts, it diversely contained four or five of the elements of inquiry in field geology, including spatial thinking and diachronic thinking in a high proportion, and also frequently used activities that require specialized skills such as geological mapping. Fieldworks for science teachers were found to have mixed features of K-12 and geology-related major students. Considering the diversity of included inquiry elements, similarities with the activities performed by geologists, and the autonomy of learners, it was analyzed that geologic fieldwork for geology-related major students was more close to authentic geologic inquiry than fieldwork for others. Based on the results of this study, we suggested implications for improving geological fieldwork as authentic science inquiry.

문명이 발전함에 따라 인류는 자연을 이용하는 방법을 깨우치기 시작했다. 그래서 인류가 시작한 최초의 자연과학을 지질학이라고 할 수 있다. 고대 그리스의 학자 헤로도투스, 스트라보 등이 지질학의 출시를 이루고 있으며 종교개혁 이후 레오나르도 다빈치가 등장했으나 종교적 박해로 그의 주장을 올바르게 펴지 못했다. 17세기 아일랜드 대주교 어셔와 덴마크 출신 의사 스테노 등이 암석 등 지구의 생성과정을 본격 연구했고 18세기 들어 스코틀랜드의 허튼이 관찰한 풍화와 침식의 과정이 발표됨으로써 현대 지질학이 탄생된 것이다.

We should treat carefully the one related to human rights among a large number of decision-making in our daily lives. As it is necessary to obtain physical evidences in the process of criminal investigation for solving a certain crime based on the principle of evidence, it leads to an increase in demand for forensic science and forensic geology. Forensic geology could be regarded as a fusion discipline of geology and forensic investigation and it is principally concerned to the study on the connection of a suspect and a crime scene with soil evidence which could be experimented using geological data and methods. So these results could be used as valuable information in a court. After its academic foundation has been builded since the last 1970s, its research objects have been expanded from soil evidence like rocks, minerals, soils, sediments to sociocultural, political, military and medical objects like ancient relics, mines, corpses. Its role is expanded from the simple finding of a particular location to the examination of archaeological theories and historical facts, the testimony of the cause of environmental pollution and the chronic demonstration of geological distribution of plants and anthropological origination. And these bring this discipline promptly to accept developed geological methodologies and to satisfy various forensic geological needs. Specialized forensic investigation institutes work actively for the R&D activities of forensic geology. In Korea, national institute of scientific investigation works a small part of forensic geological activities in total activities of forensic investigation. In conclusion, we concern to the importance of systematic discussion of building in proper position of forensic geology through its R&D methods, application cases of its performance and etc. based on geological characteristics in our country by a specialized geoscience institute.

Since the mid-twentieth century, geology has gradually evolved as an interdisciplinary context in South Korea. The journal of Economic and Environmental Geology (EEG) has a long history of over 52 years and published interdisciplinary articles based on geology. In this study, we performed a literature review using topic modeling based on Latent Dirichlet Allocation (LDA), an unsupervised machine learning model, to identify geological topics, historical trends (classic topics and emerging topics), and association by analyzing titles, keywords, and abstracts of 2,571 publications in EEG during 1968-2020. The results showed that 8 topics ('petrology and geochemistry', 'hydrology and hydrogeology', 'economic geology', 'volcanology', 'soil contaminant and remediation', 'general and structural geology', 'geophysics and geophysical exploration', and 'clay mineral') were identified in the EEG. Before 1994, classic topics ('economic geology', 'volcanology', and 'general and structure geology') were dominant research trends. After 1994, emerging topics ('hydrology and hydrogeology', 'soil contaminant and remediation', 'clay mineral') have arisen, and its portion has gradually increased. The result of association analysis showed that EEG tends to be more comprehensive based on 'economic geology'. Our results provide understanding of how geological research topics branch out and merge with other fields using a useful literature review tool for geological research in South Korea.

This study is a research synthesis analyzing how field geology education is conducted in domestic and foreign countries in the recent 20 years and how it reflects the characteristics of authentic geologic inquiry. For these purposes, we first drew five elements of inquiry in field geology (observation, representation, abductive reasoning, spatial thinking, and diachronic thinking) considering the field geologists' actual research method as well as its pedagogical significance in science education. We developed analysis criteria for field geology education. The 53 cases were analyzed based on each element of inquiry in field geology and its sub-elements, and also the tendency of overall elements. As a result, observation and representation were included in most cases, but there appeared less frequency in order of abductive reasoning, spatial thinking, and diachronic thinking. For observation, the ratio of purposive observation and autonomous observation is high. For representation, both visualizing and linguistic type of representation and free-form representation appear frequently. For abductive reasoning, the step of generating hypothesis is often included and the hypothesis tends to be about the geological formatting process. For spatial thinking, type of self-location and perception of the spatial configuration of the structure appear at a high rate. For diachronic thinking, type of stratigraphic sequence is the most frequent. The proportions of the cases including three or more elements of inquiry in field geology consist 87% of the total. We suggested implications for improving geological fieldwork as authentic science inquiry in the future.

Earth Science is the study of Earth, where diverse organisms live, and it mainly focuses on the healthy, wealthy, and comfortable environment for our descendants. UNESCO and IUGS recently established the International Working Group on Medical Geology (1996), IGCP 454 Medical Geology (2000-2004), and International Medical Geology Association (IMGA, 2006) with the primary concerns of increasing awareness of Medical Geology among scientists, medical specialists, and the general public. Medical Geology and IMGA have been very successful in informing(educating) about the relationship between geological factors and health problems in humans and animals in the world through numerous international meetings, seminars, workshops, symposiums, and publications. Since there is a close correlation between Earth Science and Medical/ Dental Sciences as shown in the Medical Geology and IMGA, Earth Science, as with other areas in science, (i.e., Biology, Chemistry and Physics) should be included in the Medical Education Eligibility Test (MEET) and Dental Education Eligibility Test (DEET) for the Medical and Dental Graduate School. In this brief note, services and activities of UNESCO IGCP 454 Medical Geology and IMGA are introduced, sothat the inclusion of Earth Science as a subject requirement in the MEET and DEET can be considered. Such outcome will balance the development of Science Education in Korea.

In this study, an investigation was conducted on the features, events, and processes (FEP) that could impact the long-term safety of the natural barriers constituting high-level radioactive waste geological repositories. The FEP list was developed utilizing the IFEP list 3.0 provided by the Nuclear Energy Agency (NEA) as foundational data, supplemented by geological investigations and research findings from leading countries in this field. A total of 49 FEPs related to the performance of the natural barrier were identified. For each FEP, detailed definitions, classifications, impacts on long-term safety, significance in domestic conditions, and feasibility of quantification were provided. Moreover, based on the compiled FEP list, three scenarios that could affect the long-term safety of the disposal facility were developed. Geological factors affecting the performance of the natural barrier in each scenario were selected and their relationships were visualized. The constructed FEP list and the visualization of interrelated factors in various scenarios are anticipated to provide essential information for selecting and organizing factors that must be considered in the development of mathematical models for quantitatively evaluating the long-term safety of deep geological repositories. In addition, these findings could be effectively utilized in establishing criteria related to the key performance of natural barriers for the confirmation of repository sites.
