  • In the celebration of the $50^{th}$ anniversary of the Korean Earth Science Society, the whole articles published in Journal of the Korean Earth Science Society (JKESS) were quantitatively analyzed. JKESS has played a major role in exchanging academically among earth science education specialists and in educating next generation for the last 36 years since it was founded in 1979. The total number of 1544 articles in thirty five volumes about the earth sciences and the earth science pedagogy has been published by August, 2014, and the number of the yearly published articles has been increasing. Regarding the research area, 69.3% was published in earth sciences and the other 30.7% was in earth science education; the percentage of research articles in geology, atmospheric science, environmental science, oceanography, and astronomy was 55.2, 17.6, 16.0, 6.0, and 5.2%, respectively. The number of research articles on atmospheric science and environmental science has recently been increasing, whereas, earth science education research articles have been" decreasing, which was similar to the pattern seen fifteen years ago. We thought that one of the reasons was related to a new journal named, "Journal of the Korean Society of Earth Science Education" started to publish in December, 2008. The number of articles authored or co-authored with foreigner scholars was totaled 53, which is only 3.4% of the entire number of published articles. It suggests that international advertisement via public relations as well as the development of English homepage be necessary. In order to become an excellent registered academic journal, it is the time to comprehensively discuss how to improve both the quality growth and the quantity of JKESS. According to the Ministry of Education, it is now in its planning stage to convert the current registration system of the academic journals to the autonomous evaluation system in academia. Therefore, we recommend that Journal of the Korean Earth Science Society be prepared for the upcoming future change.

  • 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.

  • The purposes of this study were to analyze the level of Earth science vocabularies in the 10th grade textbooks with the Science Word Analysis (SWA) program and to investigate the vocabularies selected by the 10th grade students as difficult ones. For this purpose, we extracted the Earth science vocabularies from eleven textbooks, and classified into scientific and non-scientific vocabularies with the SWA program based on the standard Korean language dictionary. In addition, we investigated the difficulty of each vocabulary by surveying five hundred sixty students with a questionnaire. Results showed that the frequency of the scientific vocabularies that were beyond the designated level was the largest among any other levels in all textbooks. Most of the vocabularies selected by students as difficult ones to understand were classified into out of the level. From these results, it were suggested that the students' cognitive level should be considered when developing science textbooks and difficult vocabularies should be replaced with easy ones without a change of meaning.

  • The purpose of this study is to evaluate the content knowledge and problem solving process used by pre-service earth science teachers while discriminating faults on geological maps. For this, we collected and evaluated data on fixation duration and gaze plot, while pre-service earth science teachers (N=12) solved the problem on faults interpretation using an eye tracker (Tobii Pro Glass 2 model). The results were as follows. First, most of the pre-service earth science teachers know the concepts of the normal and reverse fault but they do not know the procedural knowledge essential for fault interpretation on geological maps. Second, the pre-service earth science teachers did not draw a geological cross-sectional map to interpret the fault on the geological map and interpreted the fault based on two-dimensional information collected from the geological map rather than three-dimensional information. Therefore, it is essential to improve the teaching and learning environment so that pre-service earth science teachers who will become earth science teachers in the future can learn procedural knowledge essential to comprehend natural phenomena including understanding natural phenomena. The results of this study can substantially help organize a new earth science curriculum or develop materials on teachers' education in the future.

  • A system for continuous-wave coherent Doppler lidar (CW lidar), made up of all-fiber structures and a coaxial transmission telescope, was set up for wind measurement in Hefei (31.84 N, 117.27 E), Anhui province of China. The lidar uses a fiber laser as a light source at a wavelength of $1.55{\mu}m$, and focuses the laser beam on a location 80 m away from the telescope. Using the CW lidar, radial wind measurement was carried out. Subsequently, the spectra of the atmospheric backscattered signal were analyzed. We tested the noise and obtained the lower limit of wind velocity as 0.721 m/s, through the Rayleigh criterion. According to the number of Doppler peaks in the radial wind spectrum, a classification retrieval algorithm (CRA) combining a Gaussian fitting algorithm and a spectral centroid algorithm is designed to estimate wind velocity. Compared to calibrated pulsed coherent wind lidar, the correlation coefficient for the wind velocity is 0.979, with a standard deviation of 0.103 m/s. The results show that CW lidar offers satisfactory performance and the potential for application in wind measurement.

  • The purpose of this study was to compare what meanings of earth science pre-service teachers and primary pre-service teachers about science books and reading through science disciplinary reading and how their thoughts on science education are reflected in the science disciplinary reading process. For the study, 24 third-year students majoring in earth science education and 25 second-year students majoring in primary education were selected as subjects for the study at a teacher training college located in the central part of Korea. As a result of the study, first, earth science pre-service teachers used disciplinary reading a lot to acquire knowledge of science content, but primary pre-service teachers used it for the purpose of using it in class, scientific interest, and curiosity solution. Second, earth science pre-service teachers and primary pre-service teachers showed differences in their thinking in using science related books for science education. While earth science pre-service teachers rarely described the use of science books in their classes, primary pre-service teachers actively described science classes. Third, from the perspective of science disciplinary reading, primary pre-service teachers were more actively emphasizing the meaning of disciplinary reading compared to earth science pre-service teachers. In light of the research results that the reading activity in science has a lot of effect, it is thought that a wide range of research on science disciplinary reading should be conducted as a teaching strategy in school field classes.
