한국지구과학회 창립 50주년을 맞아 1979년 창간 한 이후 36년간 지구과학과 지구과학교육 전문가들의 학술교류와 다음 세대 교육에 큰 역할을 한 한국지구과학회지에 출판된 논문을 정량적으로 분석하였다. 한국지구과학회지를 통하여 2014년 8월 기준 35권 1,544편의 논문이 실렸고, 년 간 실리는 논문 수도 증가하여 왔다. 한국지구과학회지에 실린 논문들은 지구과학 내용학 관련 논문이 69.3%, 지구과학 교육학 논문이 30.7%이며, 내용학 논문 중 지질학 55.2%, 대기과학 17.6%, 환경과학 16.0%, 해양학 6.0%, 천문학 5.2%의 분포를 보였다. 최근 들어 대기과학과 환경과학 논문 수가 크게 증가하고 있으나, 지구과학 교육학 관련 논문수는 15년 전 수준으로 감소하였다. 이는 2008년 12월 창간호를 낸 대한지구과학교육학회지의 창간과 관련이 있는 것으로 보인다. 한국지구과학회지에 게재된 외국인 저자들의 공동 참여 논문 수는 53편으로 전체 논문의 3.4%에 불과하여 한국지구과학회지가 우수등재학술지로 정착하기 위해서는 학회지의 양적인 팽창 뿐만 아니라 질적인 성장에도 관심을 기울여야 할 것으로 생각되며, 영문 홈페이지 개선과 함께 국제적 홍보가 필요하다고 생각된다. 교육부는 앞으로 학술지 등재제도의 지나친 문제점의 발생으로 학술지 등재제도 폐지를 통한 학계 자율평가체제로의 전환을 구상 중이며 한국지구과학회지도 이러한 미래의 변화에 대해 철저히 준비하여 학회의 위상을 제고하여야 할 것으로 생각된다.

Curriculum reform has been a significant emphasis for most of countries all over the world for the past few years. It was the first time for Taiwan to develop a new Science and Life Technology curriculum Standards (SaLTS) for grades 1 through 9 compulsory educations. The SaLTS features integrated science content with the aim at motivating students to learn science and encouraging students to apply science to their everyday life, which is practically well aligned with the philosophical essence and foundations of Earth Systems Education (ESE). This paper calls attention to the importance of the inclusion of ESE into the forthcoming science curricula of Taiwan and worldwide and provides some exemplary ESE-inspired curriculum and instructional modules that have been successfully implemented in the secondary schools of Taiwan. Hopefully, this paper can shed some lights on the future development of the ESE-based science curricula, instructional modules, and teacher preparation programs.

The purpose of this research is to accomplish the goal of science education based in the seventh science course of study by suggesting the plan for development of executable method in the learning process of Earth Science education and establishing a practical model to evaluate its achievement. Furthermore, the idea of this research is to recognize a way of using and consideration at practical use of the model. Since the purpose of the educational evaluation is to maximize the efficiency of school studying, there are some negative aspects in our current method of evaluation to achieve the purpose. New system has been introduced into the educational evaluation to resolve such a critical issue. Despite some positive aspects in the system, it could not be escaped from the multiple choice and pens examination. This could be caused by in various limitations, especially the insufficiency of teachers' awareness and the data about the Performance assessment. This research is to develop and use the practical model for the Performance assessment in consideration of current educational circumstances of Junior and High school. The model of the Performance assessment in this research is to sufficiently evaluate student's ability and skill in the learning process of Earth Science education. Hence, it is dedicated to the education for human being and improve quality in the learning process of the Earth Science education among the modern society, which is characterized globalization and information. Furthermore, it may promote the growth of various character of students and increase creativity and skill for the problem solving.

Unarmored dinoflagellates, in the family Kareniaceae, include harmful or toxic bloom-forming species, which are associated with massive fish kills and mortalities of marine organisms worldwide. The occurrence and distribution of the toxigenic species in the family Kareniaceae were investigated in the brackish and coastal waters of Korea between July 2018 and October 2020. During the survey, we collected seven newly recorded species; Karenia papilionacea, Karlodinium digitatum, Karl. veneficum, Karl. zhouanum, Takayama acrotrocha, T. helix, and T. tasmanica. A total of fifteen strains of the seven taxa were successfully established as clonal cultures and examined using LM, SEM, and molecular phylogeny inferred from LSU rDNA sequences. Herein, we present the taxonomic information, morphological features, and molecular phylogenetic positions of the unrecorded dinoflagellate species collected from Korean coastal waters.

SAR (Synthetic Aperture Radar) is an imaging radar which can scan and image Earth System targets without solar illumination. Most Earth observation Shh systems operate in X-, C-, S-, L-, and P-band frequencies, where the shortest wavelength is approximately 1.5 cm. This means that most opaque objects in the SAR signal path become transparent and SAR systems can image the planetary surface targets without sunlight and through rain, snow and/or even volcanic ash clouds. Most conventional SAR systems in operation, including the Canada's RADARSAT-1, operate in one frequency and in one polarization. This has resulted in black and with images, with which we are familiar now. However, with the launching of ENVTSAT on March 1 2002, the ASAR system onboard the ENVISAT can image Earth's surface targets with selected polarimetric signals, HH+VV, HH+VH, and VV+HV. In 2004, Canadian Space Agency will launch RADARSAT-II, which is C-band, fully polarimetric HH+VV+VH+HV. Almost same time, the NASDA of Japan will launch ALOS (Advanced land Observation Satellite) which will carry L-band PALSAR system, which is again fully polarimetric. This means that we will have at least three fully polarimetric space-borne SAR system fur civilian operation in less than one year. Are we then ready for this new all weather Earth Observation technology\ulcorner Actual imaging process of a fully polarimetric SAR system is not easy to explain. But, most Earth system scientists, including geologists, are familiar with polarization microscopes and other polarization effects in nature. The spatial resolution of the new generation of SAR systems have also been steadily increased, almost to the limit of highest optical resolution. In this talk some new applications how they are used for Earth system observation purpose.

Since 1990, Agency for Defense Development is operating the non-magnetic laboratory for the development of key technology for the underwater magnetic stealth part, the research of the magnetic application weapons and the technical support for Korean Navy. Recently, we installed the new three-axis earth magnetic field simulator and the measurement system in the non-magnetic laboratory which is replacing the existing outdated facility. In this paper, we deal with the detailed design result of the earth magnetic field simulator and the measurement system. Also, we describe the effective method to separate the permanent and the induced magnetic field from the measured data for a scaled model ship using the earth magnetic field simulator and the measurement system.

In this paper, we aimed to examine the flowering dates of cherry blossom and the peak dates of maple leaves in South Korea, by the combination of temperature observation data from ASOS (Automated Surface Observing System) and NDVI (Normalized Difference Vegetation Index) from MODIS (Moderate Resolution Imaging Spectroradiometer). The more recent years, the faster the flowering dates and the slower the peak dates. This is because of the impacts of climate change with the increase of air temperature in South Korea. By reflecting the climate change, our statistical models could reasonably predict the plant phenology with the CC (Correlation Coefficient) of 0.870 and the MAE (Mean Absolute Error) of 3.3 days for the flowering dates of cherry blossom, and the CC of 0.805 and the MAE of 3.8 for the peak dates of maple leaves. We could suppose a linear relationship between the plant phenology DOY (day of year) and the environmental factors like temperature and NDVI, which should be inspected in more detail. We found that the flowering date of cherry blossom was closely related to the monthly mean temperature of February and March, and the peak date of maple leaves was much associated with the accumulated temperature. Amore sophisticated future work will be required to examine the plant phenology using higher-resolution satellite images and additional meteorological variables like the diurnal temperature range sensitive to plant phenology. Using meteorological grid can help produce the spatially continuous raster maps for plant phenology.

중력계는 주로 지하 광물자원 탐사 및 지구조석과 같은 장주기 이벤트를 관측하는데 사용되고 있다. 최근 연구자들은 이 중력계를 이용하여 대형 원거리 지진 및 지진상시잡음 관측과 같은 몇몇 새롭고 흥미로운 사실들을 발견하였다. Micro-g LaCoste사의 gPhone에 적용된 zero-length spring suspension 기술은 초저주파 신호도 훌륭히 관측 가능하게 하며, 이는 Earth's hum이나 심지어 대형 지진해일 등을 관측하는데 큰 도움을 줄 수 있음을 시사한다. 이 연구에서는 충남 금산에서 2008년 11월 부터 2009년 7월까지 9개월간 임시로 설치/운영하였던 gPhone 자료를 분석하여 원거리 대형 지진관측 및 상시지진잡음의 계절적 변화에 관한 사전결과를 보고하고자 한다.
